We'll check on the spot

In fact, both the installation of the new engine itself and the modernization of products required the factory workers to make a number of design changes. The updated Sadko has a strengthened frame, new double-cone synchronizers in the gearbox, different driveshaft crosspieces, and there are a lot of small innovations. Polyamide pipelines of the fuel system, new power unit supports, the design of the steering mechanism was measured, and a heated filter separator.

The new engine, since it is equipped with an electronic control unit, required, in turn, electronic drives for the accelerator pedal, speedometer and tachometer. The first thing you notice when you get into the cab is that the odometer now has no wheels. And for some reason, once again today I felt warm and good: an old, familiar, one might say, dear car, but in a new interpretation. But the changes did not affect the well-known bent gearshift lever, the steering column is still not adjustable, and the wiring and contacts in some places look like they were made by a schoolboy in a labor class, and even then with a C grade.

It’s okay, everything can be brought to mind, it would be for the sake of it - I have no aversion to this car, even if I flog it! And I am perfectly aware that if it were any, the most shabby “bourgeois,” I would not forgive him for anything like that! And rightly so! The amount that its manufacturers are asking for the new Sadko is a textbook example of the relationship between price and no, not quality, but rather a combination of qualities, a set of capabilities, consumer and operational properties. Now let's go! On the landfill road, virgin lands, country roads, snow, ice, asphalt.

Scheme GAZ 3309 diesel

Scheme GAZ 3309 diesel four-stroke, turbocharged, liquid-cooled, with a displacement of 4.75 liters and a power of 147 hp. The diesel engine is equipped with a high-pressure fuel pump with a booster pump.

Scheme GAZ 3309 Diesel D-245 is a 4-stroke piston four-cylinder internal combustion engine with an in-line vertical cylinder arrangement, direct injection of diesel fuel and compression ignition.

The main elements of the GAZ 3309 diesel engine are: cylinder block, cylinder head, pistons, connecting rods, crankshaft and flywheel.

To ensure high technical and economic indicators of the diesel engine, turbocharging with intermediate cooling of the charge air is used in the intake system.

The use of a turbocharger with adjustable boost pressure in the supercharging device allows for improved throttle response on a diesel engine, provided by increased torque values at low crankshaft speeds.

Generator circuit GAZ 3309

Generator circuit 5101.3701 GAZ 3309 with diodes and voltage regulator YA120M1. Old style diode bridge BPV 56-65-02 with two wires. The GAZ 3309 generator consists of a housing, stator winding, rotor, diode bridge and built-in voltage regulator.

The GAZ 3309 generator circuit, thanks to a system with additional diodes, allows you to receive current from the output of additional diodes, and not from the generator output as before. Thanks to this scheme, battery discharge through the generator excitation winding is practically reduced to zero. The current in a similar circuit of the GAZ 3309 generator flows only inside the generator itself, without using external circuits and the ignition switch (except for the initial excitation).

Verification methods

Given the external similarity of the electrical equipment, the automaker reasonably assumed the possibility of errors when servicing the car independently, the price of which was high. Therefore, I provided automatic protection of elements from accidental short circuits:

The generator excitation winding circuit is protected using a protection relay, as well as a separating diode;
While the engine and generator are running, the relay contacts are open;
If a wire breaks or short circuits, the current flowing through the relay winding will increase;
The opposing winding will create a magnetic field, the core will retract and open the relay contacts (see also the VAZ 2101 wiring diagram).

GAZ 3309 GAZ 3309 diesel dump truck
GAZ-3307 is a medium-tonnage truck, produced since 1990 at the Gorky Automobile Plant. The machine is quite reliable, but sometimes some malfunctions occur, including electrical equipment for gas 3307. Any of its elements can fail. To find and fix problems, use the car's electrical diagram. Anyone can learn to read and understand it.

Truck GAZ 3307

Description

The electrical circuit of the GAZ-3307 is a drawing on which there are pictograms of the electrical elements of the car, connected to each other by switching lines indicating wires. The equipment is located approximately where it is when looking at the machine from above, although deviations (sometimes significant) are possible. On the left are usually the headlights and sidelights of the front of the car, to the right are the electrical equipment of the engine compartment, interior and rear lights.

Electrical circuits are available in black and white and color. The latter are easier to read; the colors of the lines are the same as those of the corresponding wires. Often electrical components are shown in the form of pictures (instrument panel, starter, headlights, etc.), they can be recognized without looking at the “legend” (the explanatory text under the diagram or on the side of it). An example of a color wiring diagram is shown below.

Black and white diagrams are usually more detailed and often provide additional information (for example, thin lines show current conductors inside devices). The color of the wires is indicated by a letter (H - black, Z - green, and so on). The numbers (2; 0.5 and others) in the breaks in the switching lines indicate the cross-sectional area of the wire in square millimeters. There are standard pictograms and conventional images of certain devices. Next to them (sometimes on a callout) is a number or letter with numbers. This is the designation of the element whose name is indicated in the “legend”.

Troubleshooting

If any device fails, using an electrical circuit it is easy to check whether it has failed or whether the electrical circuit has been interrupted somewhere.

Power supply circuit for a GZ-3307 car. To do this, you will need a test light with wires and clamps or a tester turned on in voltmeter mode (voltage detection). We connect one clamp of the light bulb (tester) to the input contact of the element being tested, the other to the “ground”, that is, the negative terminal of the battery or any part of the frame, body or engine (cleaned of paint).

...and beyond

We get stuck, we shake, but we crawl, and we can’t reduce the speed - there won’t be enough torque, and if we add more, we slip, but still, even if it’s just a gram or a millimeter, we’re still crawling. And why were we given this hill? Oh, yes, testing and photography... If you slow down, you’ll be afraid of stalling, and then you’ll definitely never move again without outside help, if you add, you’ll skid in vain, or worse, you’ll dig in. Where is the golden mean? Go and look... At this very moment, the new modern diesel engine with electronic control shows itself in all its glory: attempts to stall begin only when the speed approaches 500 min -1, and you can safely spin it up to slightly clear the tread of loose snow to the maximum permissible 2300 min -1, and only after a good forty minutes of such cruel cycles, when the transfer case was switched on in a low range, with complete blocking, the warning lamp of the starting overheating of the coolant blinked a couple of times. But as soon as you reduce the load a little and add heating, the temperature calmly drops to a safe 80º. Here it is, the treasured “hill”. Now the long-awaited photo shoot is taking place, and the car is on a smoke break. After such a “special stage”, out of old habit, I want to check the tightness of all threaded connections and the condition of other fasteners. This is our own gas car! But now it no longer stalls at idle, does not choke from lack of torque, does not throw black soot into the exhaust pipe and does not consume tons of expensive fuel. Well done keep it up!

GAZ 3309 starter: where is it located, how to remove, replacement

GAZ 3309 is a popular truck that was produced in the USSR; later, another modification of the vehicle began to be produced in Russia; its main difference was that the gasoline engine was replaced with a diesel engine, which is labeled as MMZ D-245.7E4.

It has several modifications, the most popular version is an engine that produces 125 “horses” and complies with the Euro-4 environmental class. It is worth noting that there is another diesel engine, but it is less common.

The car is still in production, despite all its modern competitors, and the GAZ 3309 is still a frequent participant in road traffic in our country. The whole secret is the simplicity of the device and the reliability of spare parts. Of course, any mechanism has its own resource, and the GAZ 3309 also has breakdowns. Let's touch on the issue of the starter of this car in more detail.

Types of faults

Sometimes people mistakenly blame the starter, but in the end it turns out that it is not the fault. The thing is that the starter works in conjunction with other systems and components of the car (starting-charging circuit).

In general, all starter failures can be divided into two large groups:

Mechanical faults,
Electrical breakdowns.

Each group has its own nuances, so it is worth considering them in detail.

Electrical breakdowns

If the starter does not turn the engine at all or does so very slowly (with insufficient power to start the engine), you must first check the electrical circuit. This must be done from the battery to the starter.

The rechargeable battery (AB) should be given special attention in this matter. Need to check:

Charge (the battery must be fully charged),
Ground contacts (they must be reliable and well secured),
Wire from the solenoid relay terminal (integrity and good contact),
Wire from the battery to the starter (integrity and good contact),
Contact group of the ignition switch (serviceability).

The above-mentioned problems occur when it is possible to turn the key in the ignition switch, but there is no activation of the retractor relay (the armature does not rotate) or there is a break in the winding of the traction relay, as well as a short circuit of the turns or to ground. In addition, slow turning of the flywheel may indicate problems with the electrical part of the starter.

If there are no visible visual faults with the starter, then you need to dismantle it in order to examine it more carefully. Thus, it is possible to determine whether the commutator is burning or to find a short circuit in its plate.

But the experience of studying the issue suggests that the most common electrical malfunction is wear or hanging of the brushes.

Now we can distinguish three main breakdowns from this category of faults:

Poor contact between the brushes and the commutator,
Broken traction relay,
Armature commutator wear.

Mechanical problems

If the starter works, but the engine does not start, then the problem is from this category. In this case, you need to check the following details:

Overrunning clutch lever,
Clutch ring,
buffer spring,
Flywheel crown.

When the starter is running, the car engine does not start for the following reasons:

Clutch slipping (failure of the release lever, its jumping off the axis, wear of the clutch drive ring or wear of the buffer spring). Defective parts should be replaced.
If a grinding noise is heard during startup, this is wear on the flywheel ring teeth. The gear travel should be checked for any blockages, and the condition of the buffer spring should be checked for functionality.
If a very strange noise is heard, then you should check from the “pit” and engine compartment for such faults as wear of the bearing sleeve, journals on the armature shaft, loosening of the starter mounting bolts and damage to the teeth. In addition, the pole inside the starter may become loose.

Diesel problems

Let's leave the topic of owners, shareholders, holdings, marketing and finance today. It’s just that now the production program of the GAZ plant from Nizhny Novgorod includes an all-wheel drive truck model GAZ-33088 “Sadko” with a new modern diesel engine model YaMZ-534 from the ancient Russian city of Yaroslavl. It was this version of the long-lived medium-tonnage conveyor vehicle, which received the index 33088, that I was invited to test at the factory test site in the vicinity of Nizhny. Of course, I happily agreed.

At the beginning of their careers, few of the road transport workers of my generation thought that foreign rolling stock would dominate modern road transportation. And it is all the more interesting to return to the roots again, to get acquainted again with cars that have survived the harsh conditions of the Russian market, have been produced for many years, but are still in demand today.

Attempts to equip off-road medium-duty trucks with a compact and economical diesel engine from GAZ OJSC have been made more than once. However, until recently, the only workable option remained the notorious obsolete Minsk D-245 engine, which had many complaints. The Yaroslavl motor offered today was created not under license, but from scratch, in collaboration with the Austrian engineering company AVL. The characteristics of power, toxicity and torque (134 hp at 2300 min -1 ; 417 N∙m in the range 1200–2100 min -1 ) are quite at the modern level, the increase in price of the base car compared to the Minsk power plant is no more than 50,000 rub. Very tempting, but how efficient is it?

Malfunctions of the ignition system of GAZ-3307

For example, let's find a fault in the ignition system, which is one of the most important in a car. Failure or poor performance of any of the elements is a serious problem, especially while traveling. The engine stalls or runs intermittently, it is advisable to quickly find and eliminate the cause.

First, make sure that the problem is in the ignition system (there may also be a fuel supply malfunction). Remove the wire from any spark plug and bring its end to ground at a distance of 6–9 mm. When the engine is cranked by the starter, a spark should appear. Be careful, the circuit is under high voltage; you should work with rubber gloves or use improvised objects that do not conduct current, for example, wooden ones, holding the wire with their help. If there is no spark, remove the central wire from the distributor cover and check it in the same way as a spark plug.

There is a spark - the problem is in the breaker-distributor (item 3), if not - let's continue the search. Make sure that current is supplied to the induction coil terminal (item 5). To do this, connect the clamps of the control light to the corresponding connector and ground: the light should light up (with the ignition on). Similarly, check the output of the switch (item 4) with the + sign. If there is current, connect a light bulb (with a power of no more than 3 W) to the short-circuit terminal and ground. It should flash when the starter is turned on. If this happens, the ignition coil is faulty.

If the light is on continuously or does not light up, the switch is faulty (unfortunately, a typical problem on the GAZ-3307).

If current is not supplied to the coil, we determine according to the diagram the next element in the circuit - the ignition switch (item 9). Both contacts must be energized (with the ignition on); if only the incoming one is energized, then the lock is faulty.

The next element in the circuit is the fuse (item 7). It must be checked if there is no voltage at the incoming terminal of the ignition switch. If a fuse is blown, try to find the cause before replacing it. Most likely, this is a short circuit; its sign is a dark spot at the breakdown site. The wire must be cleaned, the burnt ends connected (if necessary) and carefully insulated.

On road…

Before the assault on the virgin snow, “Sadko” and I decided to take a ride along a straight and deserted winter highway.

- My friend, even twenty years ago I remember your hood lifting up at speed, diagonal swing, yaw, transmission noise.

– Nothing, but the speeds are now switched on much better, especially low ones, without the characteristic “belching”; and the maximum and, mind you, artificially limited to 85 km/h is now not an example of correct adjustment of the ignition and power supply of the huge ZMZ, but just the usual capability of a compact four-cylinder “in-line” from Yaroslavl. And you can forget about strong vibration.

This is my dialogue with the “lawn” on the eve of an off-road start, and at the very end of winter, when the snow is hard and dense, the depth of cover is the maximum for the season, and skeptics always talk about utopia on the eve of their usual spring aggravation...

conclusions

We hope that in this material we were able to provide a detailed explanation of the features of the car. And the video in this article and detailed electrical diagrams will allow GAZ 3307 owners to independently detect faults in electrical circuits and restore their operating parameters (see also GAZ 3110 wiring diagram).

Controls

The location of the controls is shown in Fig.
5.1. Rice. 5.1. Controls:

1 and 8 — nozzles for blowing the cabin glass;

2 — instrument panel;

3 - lever for switching direction indicators, headlights and sound signal. The lever has six fixed positions - I, II, III, IV, V and VI and four non-fixed positions “A” (Fig. 5.2 and 5.3).

* On some vehicles, the sound signal is turned on by the windshield wiper and washer switch (see Fig. 5.5).

If the switch lever is in position I and the central light switch is in position II, then the low beam headlights are on. By moving the lever to position II, the high beam headlights come on and the blue indicator light comes on.

When the switch lever is repeatedly moved from position I towards you along the steering column (non-locking position), the high beam headlights are signaled.

Rice. 5.2. Positions of the turn signal and headlight switch lever (with sound signal)

Rice. 5.3. Turn signal and headlight switch positions (without horn)

When you press the lever button (from any position) along the axis, a sound signal* is activated (without locking) - see fig. 5.2.

When the lever is moved from position I or II up to position VI or IV (right turn) or down to position V or III (left turn), the direction indicators turn on and a green flashing warning light comes on on the instrument panel. The switch has an automatic device for returning the lever to position I or II after the end of the turn. To briefly turn on the direction indicators, the switch lever must be moved to the corresponding non-fixed position “A”. When released, the lever returns to position I or II.

4 — steering wheel.

5 — switch lever for windshield wiper, windshield washer and horn*. When the lever is in position (Fig. 5.4): O - the windshield wiper is off; I — low speed windshield wiper is on; II — high speed windshield wiper is on; III - intermittent operation of the windshield wiper is turned on.

* On some vehicles, the sound signal is turned on by the windshield wiper and washer switch (see Fig. 5.5).

Rice. 5.4. Windshield wiper and washer switch positions (without horn)

Rice. 5.5. Windshield wiper and washer switch positions (with horn*)

When the lever is in position (Fig. 5.5):

0 — windshield wiper off; I — intermittent operation of the windshield wiper is on; II — low speed windshield wiper is on; III - high speed windshield wiper is on.

If the switch does not have a horn switch (Fig. 5.4), then moving the lever towards you (in the direction of the arrow) from position 0 briefly turns on the washer and wiper.

If the switch is equipped with a sound signal switch* (Fig. 5.5), then to turn on the washer and wiper for a short time, the switch lever must be moved from position 0 away from you (in the direction of the arrow “A”), and to turn on the sound signal* the lever must be moved (from any position) toward you (in the direction of arrow “B”).

The washer can be turned on from all positions of the lever.

* On some cars, the sound signal is turned on by the turn signal and headlight switch (see Fig. 5.2).

The windshield wiper only works when the ignition is on.

6 - removable fuse block panel. On the inside of the panel there are signs indicating the consumers protected by these fuses.

7 - glove box.

9 — knob for the control unit for electric headlight adjustment, depending on the vehicle load (Fig. 5.6).

Rice. 5.6. Handle of the headlight range control unit

When the corrector knob is in position:

0 – corresponds to an unloaded vehicle;

1 - corresponds to a fully loaded vehicle.

10 — control knob for air supply to the main heater. When the handle is in the upper position, only outside air enters the heater; when in the lower position, air from the cabin enters. At any intermediate position of the handle, a mixture of outside air and air from the cabin enters the heater.

11 — control knob for the main heater tap. When the handle is in the upper position, coolant from the engine cooling system flows into the cab heater radiator.

12 - battery switch.

13 — front axle activation lever.

14 — transfer case lever.

15 — gear lever.

20 — switch for electrical equipment, starter and anti-theft device (GAZ-33081); — ignition switch, starter and anti-theft device (GAZ-3308).

Rice. 5.8. Key switch positions

The switch key has four positions (Fig. 5.8):

I - electrical equipment is turned on (GAZ-33081); ignition is on (GAZ-3308);

II - electrical equipment is turned on - GAZ-33081 (ignition is on - GAZ-3308) and starter;

III - electrical equipment is turned off - GAZ-33081 (ignition is turned off - GAZ-3308) and the anti-theft device is turned on when the key is removed. To turn off the anti-theft device, insert the key and, slightly rocking the steering wheel left and right, turn the key to position 0.

When turning off the devices - GAZ-33081 (ignition - GAZ-3308), turn the key from position I to the fixed position 0. To avoid failure of the contact part of the device switch, do not leave the key in an intermediate position.
