The ignition setting must be done with great accuracy, since even with small errors in the installation, fuel consumption increases sharply, and engine power decreases. In addition, there may be cases of breakdown of cylinder head gaskets, burnout of valves, piston bottoms,
jumpers between adjacent compression chambers in the head, etc. phenomena caused by detonation.
The opening of the current by the interrupter when setting the ignition should occur on the GAZ-51 and ZIM-12 engines at the moment corresponding to the top dead center of the compression stroke in the first cylinder, and on the M-20 and GAZ-69 engines, not reaching it by 4 °. Accordingly, the rotor must be located against the cover electrode connected to the wire going to the spark plug of the first cylinder.
If the oil pump and distributor were removed from the engine (for example, when repairing or replacing), then they must be correctly installed in their places to be able to install the ignition.
The procedure for installing an oil pump on the engine is described in the "Lubrication System" section of Chapter I when describing the oil pump.
To install the ignition distributor on the engine, you must:
a) set the engine crankshaft to the top dead center position of the compression stroke in the first cylinder;
b) make sure with the help of the mandrel shown in fig. 160 a that the oil pump is installed correctly. In this case, the pointer of the mandrel, inserted all the way into the hole for the distributor, should be directed vertically upwards, as shown in Fig. 160 b, with a deviation from the specified position of not more than 5 ° in any direction;
c) install the protrusion on the distributor shaft of the GAZ-51 and ZIM-12 engines so that it is perpendicular to the plane passing through the axes of the distributor shaft and the holes in the plate for attaching the distributor to the block (Fig. 161 a), and on the distributor of engines M- 20 and GAZ-69 so that it is in a plane parallel to the plane passing through the axis of the distributor shaft and the center of the swivel of the octane corrector rod with the bottom plate, and would be shifted towards this rod (Fig. 161 b);
In this case, the current-distributing contact of the distributor rotor must be turned towards the cover electrode connected to the wire going to the spark plug of the first cylinder;
d) carefully insert the distributor into the block so that the hole or the middle of the arc slot in the lower mounting plate of the octane corrector, intended for the screw fastening the distributor to the block, would be located against the corresponding threaded hole in the block boss.
When installing the distributor, it is necessary to ensure that its shank does not touch the walls of the hole in the block, and does not turn into its body. In this case, the protrusion on the distributor shank must fall into the slot on the oil pump shaft;
e) insert and tighten the screw that secures the lower mounting plate of the distributor to the block boss. To install the ignition, you should:
a) adjust the gap between the contacts of the distributor breaker, as indicated above;
b) set the crankshaft to a position corresponding to the top dead center of the compression stroke in the first cylinder (on GAZ-51 and ZIM12 engines) or 4 ° short of it (on M-20 and GAZ-69 engines);
c) disconnect the tube of the vacuum regulator; d) remove the distributor cover and make sure that the rotor is against the electrode in the cover connected to the wire going to the spark plug of the first cylinder;
e) after making sure that the engine compartment lamp is in good condition (turning it on and off), remove the end of its wire from the coupling and connect it with an additional piece of wire to the low voltage terminal of the induction coil to which the distributor breaker wire is connected, and turn the lamp lever to on position;
f) set the arrow of the octane-corrector scale against the "O" division. This is done for distributors equipped with a device for smooth adjustment of the octane-corrector by rotating two nuts intended for this purpose, which, after setting the arrow to "O", should be carefully locked by tightly wrapping by hand. For distributors of an earlier release, without the specified device, the arrow is set to "O" by turning the distributor body directly by hand, with a preliminary loosening of the screw securing the installation clamp to the octane corrector plate, which, after setting the arrow to "O", should be tightened again to fix the arrow and the distributor housing in this position;
g) turn on the ignition and, without violating the zero setting of the octane corrector, carefully turn the distributor housing clockwise so that the breaker contacts are closed, then slowly turn the housing counterclockwise until the light flashes, which will correspond to the moment the breaker contacts start opening. You need to stop the rotation of the distributor exactly at the moment the light bulb flashes. If this fails, the operation must be repeated by turning the distributor housing to its original position.
When setting the moment of the beginning of the opening of the contacts, lightly press the distributor rotor with your finger, trying to turn it counterclockwise (that is, against the direction of rotation) in order to select the side clearance in the distributor drive;
h) while holding the distributor body from turning, fix its position in one way or another (depending on the design of the octane corrector);
i) connect the tube of the vacuum regulator, put the cover of the distributor and the central wire in place. Check the correct connection of the wires from the candles to the distributor, starting with the first cylinder. They, counting clockwise, must be connected in the following order: 1-5-3-6-2-4 (on GAZ-51 and ZIM-12 engines) and 1-2-4-3 (on M-20 engines and GAZ-69);
j) put the hatch cover of the ignition installation in its place on the clutch housing and connect the wire of the engine compartment lamp to the coupling (in its original place).
The final check and fine-tuning of the ignition setting by listening to the operation of the engine while the car is moving is carried out using an octane corrector, the movement of the arrow of which, and with it the distributor housing, by one division of the scale corresponds to a change in the setting of the clamp -
ganiya 2 degrees, counting on the crankshaft.
When the distributor housing is turned clockwise, the ignition setting will be later; when turning counterclockwise - earlier.
Checking the operation of the engine during the final fine-tuning of the ignition is carried out as follows:
a) warm up the engine to a temperature of 70-80°C;
b) moving in direct gear on a flat road at the speed indicated in Table. 38, give the car acceleration by sharply pressing the accelerator pedal. If at the same time slight and short-term detonation is observed (mistaken by drivers for the "knock" of fingers), the ignition timing is set correctly. In case of strong detonation, turn the distributor housing one division of the octane-corrector scale clockwise, and in the absence of detonation - one division counterclockwise;
c) after such an adjustment, it is necessary to check the ignition setting again in the manner indicated above.
You should always work with an ignition system that, when the engine is heavily loaded, gives only a slight, quickly disappearing detonation. Ignition too early, when constant detonation is heard, is very harmful to the engine, as it reduces its durability and can lead to emergency breakdowns. If the ignition is too late, there is a loss of throttle response, fuel consumption rises sharply, the engine overheats (especially the exhaust manifold).
In operation, fine-tuning the ignition setting on the move of the car should be done every time after adjusting the gap in the breaker, after installing the ignition and after changing the grade of gasoline.
One of the few trucks that Russia can be proud of. All GAZ-53 systems meet all the requirements for trucks intended for operation on all types of roads. The only system with which some problems can be associated is the ignition of the car.
Tipper truck based on GAZ 53
The ignition system in gasoline internal combustion engines (ICE) is designed to ignite the gasoline mixture in the cylinders at the time of its compression. There is no such system on diesel engines - diesel fuel ignites due to a high compression ratio and its injection under high pressure.
The GAZ-53 has a non-contact transistor ignition system, the primary circuit of which produces a voltage of 12 volts. The ignition system is considered to be a battery one, consisting of sources of electric current, which can be a battery, an ignition coil, a switch, a distribution sensor, and another, which most often causes problems, since it needs to be adjusted, candles with tips, an additional resistor, a switch ignition wires of low and high voltage.
the drawing shows a complete diagram of the GAZ-53 ignition system
The ignition system is one of the most important systems in a car, since the operation of the engine, as well as the fuel consumption of the entire car, depends on its proper operation. To suppress radio interference created by high-voltage wires and candle tips, distributed resistance is installed on the former, and suppression resistors on the latter.
A B 116 brand coil is installed in the ignition system, the purpose of which is to convert low voltage current into high voltage.
In turn, the coil consists of a transformer in which an iron core is mounted. The primary winding is wound on top of this core, and the secondary winding is wound under it. The transformer itself is a steel case, which is hermetically sealed, inside it, along with the core, oil is poured. 
To service this transformer, a plastic cover is provided that can withstand high voltage.
The first had a contact-transistor ignition system, then it became a non-contact electronic. Since the contact (or contact-transistor) system is already hopelessly outdated, we will consider a non-contact system. The GAZ 53 ignition system consists of a low-voltage and high-voltage circuit. The low voltage circuit includes:
The following elements are present in the secondary (high-voltage) circuit:
- Secondary winding short circuit. It has a large number of turns and a thin copper wire.
- Ignition distributor GAZ 53. The distribution part of the distributor consists of a shaft, a distributor cover and a slider.
- High voltage wires and tips. Through them, a high-voltage impulse is supplied to the spark plugs.
- Spark plug.

When the ignition is turned on by turning the key in the lock in the primary circuit, a magnetic field is created in the breaker. When the distributor shaft rotates, the current in the primary circuit is interrupted and the magnetic field disappears. At this moment, a high-voltage pulse appears in the winding of the secondary circuit, which is distributed over the cylinders.
Ignition faults
Malfunctions in the system lead to interruptions in the operation of the engine, in some cases the internal combustion engine does not start.
This is what the ignition lock looks like in a gas 53 car
The most common causes leading to interruptions in the operation of the motor: 
The distributor itself fails infrequently and usually works out its intended resource.
Installing and adjusting the ignition
If the engine does not develop power and heats up more than normal, one of the reasons for this phenomenon may be delayed ignition.

GAZ 53 tuning options
At the same time, pops can be observed in the carburetor (intake manifold). To fix this problem, you need to set the ignition, make it early. You can also set it according to the mark, according to the strobe, but practice shows that the ignition timing is insufficient. For some reason, "old-fashioned" methods are more effective and in many cases work for sure.
The piston of the first cylinder is installed in V.M.T. at the end of the compression stroke. The crankshaft is turned until the mark on the crankshaft pulley (hole) is aligned with the TDC mark on the ignition setting indicator mounted on the maximum speed limiter sensor cover. 
Then turn the crankshaft (counterclockwise) until the mark on the pulley aligns with the mark 9 on the pointers of the maximum speed limiter sensor.
After that, the bolt securing the upper plate of the octane corrector to the breaker body is loosened. Connect the control light with one wire to ground, and the other to the breaker terminal. Turn on the ignition and slowly turn the breaker housing counterclockwise until the bulb lights up. This will correspond to the beginning of the opening of the contacts.
Then tighten the breaker mounting bolt and put the rotor and distributor cover. From the segment against which the rotor plate is installed, a wire is connected to the spark plug of the first cylinder. The remaining wires are connected to the spark plugs clockwise in the order of operation of the engine cylinders 1-5-4-2-6-3-7-8 (Figure below).
When setting the ignition on the GAZ-53 engine, you need to turn the crankshaft so that the risk on its pulley does not reach the central risk on the TDC indicator, which is attached to the engine, by four divisions.
If the ignition is too early or too late, the engine overheats, loses its power, increases fuel consumption and there are interruptions in its operation.
Correcting the ignition angle on a running engine:
- The motor is idling, we get to the distributor mounting bolt (key 10) and loosen it;
- Slightly turn the distributor counterclockwise, fasten the bolt;
- Gasping the engine, we check the throttle response of the engine. If fingers begin to ring, move the distributor back a little, clockwise. Empirically set the required lead angle.
- We check the operation of the engine on the go. If the gas 53 engine starts to work normally, further adjustment is no longer required.
As you know, trucks use such an electrical system where current consumers are connected to sources with only a single wire (the other wire goes to ground).
Wiring GAZ 53 in this regard is no exception. We will find out in this article what are the main differences between this circuit and trace the power supply circuits of the main current consumers.
First of all, we note that any electrical circuit of a car, including one such as the GAZ 53, is equipped with the following elements:
- GPT - alternating current generator;
- KTS - contact-transistor ignition system;
- start heater;
- wiring of different voltages, connecting all the elements into a single circuit.
Attention. The electrical circuit of the GAZ-53 truck is not designed for non-standard loads.
Therefore, it is forbidden to start the engine if the cable from the generator to the regulator is damaged or if it “sparks”.
Ignition system
Let's start with the ignition system. It is known that it is battery operated, with a voltage in the circuit of 12 V.
It also consists of the following components:
- switch;
- sources supplying current;
- coils;
- resistor (additional);
- ignition distributor (distributor);
- candles with their tips;
- ignition switch;
- wiring.
Let us now consider each element of the ignition system separately and find out how it functions.
- Spark plugs for GAZ 53 must have a factory clearance of 0.85 mm. They must be with a nichrome electrode - A11, A11-1, A10-H and others will do. The order of ignition can be seen in the photo below.
- The ignition distributor is used in this car so that the frequency of rotation of its roller is one minute with uninterrupted sparking. Operates simultaneously with the ignition coil. The roller must rotate clockwise.
- Ignition coil - B114-B or B116 (more advanced). It generates high voltage pulses in the ignition system of a GAZ 53 car. It has a rated voltage of 12V and a secondary voltage of 17kV.
- The ignition switch amplifies the signal from the distribution sensor and the ignition coil. (See also the article.)
Note. To connect all of the above parts and assemblies of the vehicle's electrical equipment into a single circuit, low voltage wires are used.
They must be protected by PVC insulation.
Wiring
The basic rules that are observed in working with wiring are as follows.
- Careful attention is always paid to the GAZ 53 wiring, which may be subject to various influences. If the insulation of any wire is broken, then its metal component may touch the body of the car, thereby causing a short circuit. It is not worth saying what this leads to (burning of the insulation, the occurrence of a fire, etc.).
- It is important to take into account the fact that the wires, no matter how well they are insulated, are always subjected to mechanical stress during the operation of the car. In particular, it is possible to rub the wiring on the sharp edges of car parts, excessive sagging, etc.
- In addition, special attention should be paid to the cleanliness and tightness of the connection of wires to the clamps. Care must be taken to ensure that mixtures such as gasoline or oil do not get on the surface of the wires, which can destroy the insulation and shorten the life of the wires.
- It is imperative to check the serviceability of the jumpers located between the engine, frame and cab of the GAZ 53.
Wiring diagram protection
With self-maintenance of the car, the manufacturer correctly noticed the possibility of errors and provided for automatic protection of various elements from short circuits.
- The excitation winding circuit of the generator is specially protected by a relay and a separating diode.
- During the operation of the engine, the relay contacts always open.
- If a wire break or short circuit occurs, the current flowing through the relay increases.
Finally
An interesting video in this article, photos and diagrams will show everything clearly. There are many ways to check the wiring and its circuit, as well as equipment. Naturally, the automaker provided for the protection of the main positions, but it is very important to carry out an inspection with your own hands, as required by the instructions.
As you know, the price for such services at the service station is very high, and learning how to carry out the check yourself will help save a lot.

Reliable and economical operation of the engine depends on the smooth operation of the GAZ-53 ignition system. To eliminate radio interference caused by the ignition system, the high voltage wires have a distributed resistance, and the tips of the candles have suppression resistors. The diagram of the ignition system is shown in Fig.1.

The ignition coil GAZ-53, GAZ-3307 (B 116) is used to convert low voltage current into high voltage current.
The ignition coil B 116 is a transformer, on the iron core of which the secondary is wound, and on top of its primary winding. The core with windings is installed in a sealed steel case filled with oil and closed with a high-voltage plastic cover.
Winding resistance at a temperature of 15 - 35 ° C: primary 0.43 Ohm, secondary 13,000 - 13,400 Ohm.
Maintenance of ignition GAZ-53, GAZ-3307
To protect against possible breakdown of the plastic cover, the coil must be cleaned of dirt, dust and oil, check the reliability of fastening of high and low voltage wires.
When the engine is not running, the ignition must not be left on to avoid overheating of the coil, leading to its failure. The use of other types of ignition coils is unacceptable.
The causes of a malfunction of the ignition coil can be: insulation breakdown; interturn circuit; chips and cracks in the plastic cover; burnout of the cover, ignition coils due to a lack of high-voltage wire in the socket.
In the ignition coil windings, defects most often appear due to their overheating and operation with increased spark plug gaps. Overheating occurs mainly when the ignition is on and the engine is not running.
Before removing the GAZ-53, GAZ-3307 ignition coil for replacement, you should make sure that the wires are connected to the coil terminals in good condition and reliability. The coil should be checked on a special stand together with a transistor switch, an additional resistor and a distributor.
A good ignition coil should provide uninterrupted sparking on a three-electrode needle gap with a spark gap of 7 mm from 20 to 2300 min "1 of the distributor roller and an ambient temperature of 25 ° C. If the coil does not meet these requirements, it should be replaced.
Ignition distributor (distributor) GAZ-53, GAZ-3307
The distributor of GAZ-53, GAZ-3307 (24.3706) (Fig. 2) is a generator that generates voltage pulses to control the transistor switch and to distribute high voltage current pulses to spark plugs.
The distributor automatically adjusts the ignition timing depending on engine speed and load. Automatic adjustment of the ignition moment depending on the speed is carried out by a centrifugal regulator, and from the load - by a vacuum machine.

A roller 27 is installed in the housing 1 in two bushings 26. A centrifugal regulator with a rotor 10, on which a magnet 9 is mounted, is mounted on the upper part of the shaft. .
From above, the case is closed with cover 11, in which there are leads for high voltage wires from spark plugs and the ignition coil. Shaft 27 of the ignition distributor is driven by the camshaft gear.
The centrifugal ignition timing regulator of the GAZ-53 distributor automatically changes the ignition timing depending on the speed of rotation of the engine camshaft.
Ignition advance mismatch with the speed is usually associated with seizing the weights of the centrifugal regulator or with the weakening of their springs and causes detonation, a decrease in engine power, and an increase in fuel consumption.
The vacuum ignition advance controller automatically changes the ignition timing depending on the load on the engine.
Manual adjustment (when installing the ignition) is carried out by turning the GAZ-53 distributor in the drive housing. To rotate, loosen the distributor mounting bolt.
Turning the housing of the ignition distributor by one division of the scale corresponds to a change in the advance angle by 4 ° (according to the angle of rotation of the crankshaft).
Ignition installation GAZ-53, GAZ-3307
To install the ignition GAZ-53, GAZ-3307 with the distributor removed from the engine and its drive, you must:
Set the crankshaft to the top dead center position. the end of the compression stroke in the first cylinder; put the distributor drive on the engine;
Install the ignition distributor on the engine and high voltage wires; set ignition timing.
The procedure for connecting high voltage wires from the distributor to the candles is shown in Fig. 3.
Fig.3. The procedure for connecting wires to the spark plugs of the GAZ-53, GAZ-3307 ignition distributor
A - in front of the car
The ignition timing of the GAZ-53, GAZ-3307 is set after the distributor is installed in place in the following order:
Set the crankshaft to a position where it will go to 4 ° w.m.t. the end of the compression stroke in the first cylinder, which corresponds to the position of the pointer against the fourth risk on the crankshaft pulley;
Loosen the nut of the ignition distributor drive holder;
Remove distributor cover. Press the slider with your finger against its rotation (to eliminate the gap in the drive), carefully turn the distributor housing (distributor) until the red marks on the rotor and stator align, and in this position fix the drive holder nut.
Setting the ignition moment of a GAZ-53, GAZ-3307 car must be carried out with great accuracy. The presence of even a small inaccuracy causes increased fuel consumption, a drop in engine power.
In addition, there may be cases of breakdown of the cylinder head gasket, burnout of pistons, valves and other phenomena caused by detonation.
Therefore, the ignition timing is fine-tuned on the road while driving. This is done in this way: the engine warms up to the temperature of the liquid in the cooling system 80 - 90 ° C.
Moving in direct gear on a flat road at a speed of 25 km / h, sharply press the throttle pedal to failure and let the car accelerate to 60 km / h.
If at the same time a slight and short-term detonation is observed, disappearing at a speed of 45-50 km / h, then the ignition timing is set correctly.
In case of strong detonation, turn the body of the ignition distributor GAZ-5, GAZ-33073 by one division of the octane corrector scale clockwise (each division of the scale corresponds to a rotation of the crankshaft by an angle of 4 °).
In the absence of detonation, turn the distributor sensor housing one notch counterclockwise. After correcting the ignition timing, check its correctness by listening to the engine while driving.
You should always adjust the ignition setting, which gives only a slight detonation when the engine is under heavy load. With early ignition, when a strong detonation is heard, the head gasket can be pierced and the valves and pistons can burn out.
With late ignition, fuel consumption rises sharply, and the engine overheats. A more accurate ignition setting is made using a stroboscope.

Instructions for setting the ignition. The cause of overheating of the motor and a drop in its power may be late ignition. This can be manifested by pops in the intake manifold. Therefore, you need to know how to set the ignition correctly.
The ignition system GAZ-53, GAZ-3307 - battery, non-contact transistor with a voltage in the primary circuit of 12V, consists of sources of electric current, an ignition coil, an additional resistor, a switch, an ignition distributor, spark plugs, candle tips, an ignition switch and low and high voltage. Installation is carried out by labels as follows: 1 . First you need to set the piston on the first cylinder to TDC and align the installation indicator mark with the mark on the crankshaft pulley. 2 . Next, the crankshaft must be turned counterclockwise until the marks 9 on the pointer and the marks on its pulley match.
It is necessary to set the ignition timing of the GAZ-53 accurately, since with deviations the engine power drops and fuel consumption increases. In addition, burnout of valves, pistons, breakdowns in the cylinder head gasket and other problems associated with detonation are possible. Therefore, the final adjustment is carried out on a running engine, which warms up to a coolant temperature in the range of 80 - 90 degrees. With the engine running at idle, you need to loosen the fasteners of the distributor with a wrench on "10" so that it can be turned. Slightly turning the distributor counterclockwise, tighten the mounting bolt. Pressing on the gas, how the power unit works. If you hear "ringing of fingers", that is, detonation occurs, turn the distributor clockwise in the opposite direction. By trial and error, we set the desired lead angle. The test is done on a moving vehicle. With stable operation of the power unit, tuning is no longer needed. Sometimes the distributor is pushed to the extreme position, and the adjustment was not enough. In this case, you need to check the position of the distributor drive relative to the engine. Checking with the engine off: 1 . First, marks are made on the front crankshaft pulley. They must match on the 1st and 6th cylinders. In order not to make a mistake, it is better to remove the valve cover from the first 4 cylinders and check the valves. With the correct position of the valve marks in the 1st cylinder will be free. 2 . Having removed the distributor, we examine how the drive is installed. If it is located parallel to the motor, then it needs to be replaced or repaired, adjustment, in this case, will not help. 3 . If the position of the drive is incorrect, you need to unscrew the fastening nut and remove the part. 4 . After the drive is fully installed in its place, you need to check that the groove for the distributor runs parallel to the internal combustion engine (in the direction of the car), and a small section of the bushing on the distributor looks at the 4th and 8th cylinders (towards the driver) . Empirically, you need to achieve the correct position of the distributor drive. Ignition adjustment should be carried out until, with a significant load on the engine power unit, only a slight detonation appears. If early ignition is set, this threatens to breakdown the cylinder head gasket and burn out the valves and pistons. If the spark jumps later, then the fuel consumption increases, and the motor may overheat. Fine-tuning is done with a stroboscope.

A serviceable GAZ-53 ignition coil must ensure uninterrupted sparking on a three-electrode needle gap with a spark gap of 7 mm from 20 to 2300 min "1 of the distributor roller and an ambient temperature of 25 ° C. If the coil does not meet these requirements, it should be replaced. The distributor of GAZ-53, GAZ-3307 (24.3706) (Fig. 2) is a generator that generates voltage pulses to control the transistor switch and to distribute high voltage current pulses to spark plugs. The GAZ-53, GAZ-3307 distributor automatically adjusts the ignition timing depending on the engine speed and load. Automatic adjustment of the ignition moment depending on the speed is carried out by a centrifugal regulator, and from the load - by a vacuum machine.
