How much oil should be poured into the gas 53 box?

Technical specifications

We looked at how the GAZ-53 gearbox works. Her characteristics were quite good. Let's consider the transmission capabilities.

The unit is equipped with a three-way lever, and the transmission has forward speeds and one reverse gear. The weight of the unit is 56 kilograms. The oil in the GAZ-53 gearbox is poured into a special 3-liter container.

About the causes of malfunctions

Often the main cause of all breakdowns in this box is from an insufficient amount of gear oil or its absence at all in the gearbox mechanism. Also, the incorrect use of the mechanism is often the cause of the malfunction. Often, breakdowns are associated with natural wear of gears. Less often - with a manufacturing defect (since in the USSR they were made “for centuries”). If the truck is operated in extreme conditions for a long time, this also leads to failure of the unit.

Description of the motor device

The engine of the ZMZ 53 model has become compact. And throughout the years when the engine was produced, the cross-section of the combustion chamber, stroke and diameter of the pistons remained the same. And the V-shaped arrangement of the cylinders allows the engine to increase torque and make the engine more powerful.

In the design of the Gas 53 modification engine, in the first years of production, the manufacturer used K126B carburetors. These elements had two chambers. And a mesh filter device was placed in front of the carburetor. Thanks to this, environmental standards were observed.

The design of the Gas cylinder engine also includes:

Lubrication system;
cooling system.

Recently, engineers have been installing updated cylinder heads. The valves were placed at the top of the engine. All this contributed to improving the technical parameters of the Gas 53 engine.

The operating order of the cylinders was the following combination: 1-5-4-2-6-3-7-8. Engineers installed a combined lubrication system. The oil is supplied with pressure and sprayed. Thus, the wear of the motor and its parts during operation was reduced.

Attention! The oil is purified using a centrifuge. The pressure is obtained through a pump, which is driven by gears.

The lubricant in the radiator is cooled. Circulation passes through all vehicle systems. Therefore, the car can drive equally well in both cold and hot weather. The engine does not overheat and starts easily in harsh winters.

There are several types of engine models. However, the design did not undergo major changes in any new model.

There were other modifications as well. However, they had only an experimental type of development. Never used in mass-produced vehicles.

GAZ-53. gearbox: characteristics, design, maintenance and repair. Spare parts GAZ-53

The GAZ-53 truck is the famous Russian “toiler”. The car was produced serially from 1961 to 1993. But, despite the cessation of production in these years, this car is still found in the fleets of most companies. Also, this car is considered to be owned by personal owners. Due to the fact that the truck was assembled perfectly, the same high-quality, non-durable spare parts were used for assembly, the GAZ-53 managed to survive to this day. The only thing that sometimes raises questions about the 53rd LAWN is the box. Let's look at how such a unit is structured; ordinary faults are not repair methods.

Story

The trucks assembled as the first ones not designated with the “F” indices were equipped with six-cylinder power units, not counting the rear axle from the GAZ-51 model. How much oil to pour into the box of an alpha 50 cc moped? The box was also taken from the car for this reason, but before they were modernized. It should be noted that, if desired, you can change the GAZ-53 gearbox to a GAZ-51. As annoying as it may sound, such a substitution is rarely the most ideal. The gearbox that was installed on the GAZ-51 was distinguished by different gear ratios; it was not created to work with engines of the lowest power. The assembly of the GAZ-53F models was completed, and the GAZ-53A began to be created instead. This model was equipped with a V8 engine; to work with this unit, engineers had to modify the box and not develop the latest design of rear drive axles. Old units showed poor results during testing and were not even able to cope with the loads.

In early batches of the GAZ-53, the gearbox was equipped with synchronizers, which were designed to make switching smoother. In later versions, for this reason, it was decided to abandon them - engineers began to consider them archaic.

GAZ-53 gearbox device

A mechanical four-speed gearbox (the only one for the GAZ-53) was installed on the truck. The gearbox was equipped with five speeds - four front, one rear. Changing the oil in a Ford Fiesta gearbox is quite simple and How much oil is in a Ford Fiesta gearbox? There are three shafts inside.

The unit consists of a metal body, a cover equipped with forks for switching, shafts, and gears. The device also contains a gear block for reverse gears and not bearings. The design has a clutch for connecting fourth not third gear.

Principle of operation

The GAZ-53 gearbox operates according to the following scheme. The front part of the input shaft is fixed in the crankshaft bearing. The primary shaft is connected to the secondary shaft at the rear via a needle bearing. The torque is transmitted through the intermediate shaft. Any transmission has different gear ratios. Using this fact, the speed and thrust are changed. The smooth gear on the GAZ-53 gearbox is 4th, just like on most cars.

How does the checkpoint work?

When the lever is moved to the left from neutral, one of its parts moves the shift fork, not the rod, which forces the first gear gear to move backward, and does not engage it with the gear responsible for first gear. The latter is installed on the intermediate shaft. When the clutch is engaged, the torque is transported through the gears, which are constantly in mesh, towards the intermediate shaft to the secondary shaft.

To engage the third speed, the selector is moved from neutral to the right, and then forward. Under the influence of the fork, the synchronizer clutch will begin to move backward, then this mechanism will begin to affect the synchronizer. Here the torque comes from the gearbox input shaft through gears that are constantly coupled. The moment is transported through the intermediate shaft to the secondary shaft of the box.

To engage fourth speed, the selector must be moved from neutral to right. Then the lever is turned back. The clutch will move forward and the synchronizer ring will engage the input shaft.

Replacement is carried out on a lift or in an inspection ditch. Then, after balancing the speeds, the gear will engage.

To use reverse gear, you need to overcome the force of the safety system that allows you to conduct accounting (software). The lever must be moved to the right.

Synchronizer device and operating principle

As already seen above, the first samples have the basic GAZ-53 gearbox. Its device means synchronizers. Let's look at how they work and how they are structured. With the help of a synchronizer, 3rd and not 4th gear is engaged. This mechanism is actually a hub, which is attached to the secondary shaft of the gearbox. On its outer surface there are slots along which the coupling moves. The latter is controlled by a fork. In the grooves of the hub there are blocking “crackers”, not locking springs. Bronze blocking rings are placed along the edges. The rings have an internal cone and a gear ring on the outside. The third gear has special tapered surfaces on the input shaft gear. When switching, the blocking rings contact all these surfaces, and then they develop friction. For this reason, the rotation speeds of the shafts and gears are equalized. Gears shift more smoothly.

The unit is equipped with a three-way lever, and the transmission. forward speeds and one reverse gear. The weight of the unit is 56 kilograms. The oil in the GAZ-53 gearbox is poured into a special 3-liter container. Let's look at the gear ratios of this transmission. For first gear – 6.55. For the second – 3.09.

How much and what kind of oil should I buy for the engine? The fourth speed is direct, and the gear ratio is 1. The reverse speed has a parameter of 7.77.

Signs of transmission failure

On a GAZ-53, the gearbox rarely fails. Malfunctions can be identified by certain signs. Breakdowns are accompanied by noise and extraneous sounds when the unit is operating.

Malfunctions will be indicated by noise near the place where the unit is installed. Sometimes the transmission cannot be switched on. And if it turns out that serious effort is required. this is also a sign of a breakdown. If any gear does not work and does not engage, the speed drops, it is worth inspecting the transmission in more detail. Also, noise during movement indicates a breakdown. Often on the GAZ-53 the gearbox did not allow the lever to be moved to neutral. Because of this, it was impossible to turn off the transmission.

About the causes of malfunctions

Often the main cause of all breakdowns in this box is from an insufficient amount of gear oil or its absence at all in the gearbox mechanism. Also, the incorrect use of the mechanism is often the cause of the malfunction. Often, breakdowns are associated with natural wear of gears. Less often. with a manufacturing defect (since in the USSR they made it “for centuries”). How much brake fluid does a Ford Focus need? If the truck is operated in extreme conditions for a long time, this also leads to failure of the unit.

Extraneous sounds when the unit is operating

The transmission may make different sounds depending on what mode it is in. If an extraneous sound is heard only when the clutch is fully depressed, then the reason is the bearing. It is located on the transmission input shaft. If you put the car in gear and drive, the grinding noise indicates broken or worn teeth on the gears. Extraneous sounds when fourth gear is engaged indicate wear on the input shaft, as well as the bearings on this shaft and on the secondary one. If there is no oil in the unit, the transmission will make noise regardless of the operating modes.

Disassembling the GAZ-53 gearbox with subsequent troubleshooting and replacement of parts will help to identify the exact cause of the sounds. However, sometimes it is difficult to determine the breakdown upon inspection. Maximum attention is paid to the element located next to the noisy transmission. The box often howls. This is especially pronounced when driving at low speeds. For the 53rd LAWN, this sound is quite normal.

Gears are difficult to engage

Often, if the gears are poorly engaged, it is not the gearbox mechanism that is to blame, but the clutch. The first step is to diagnose the clutch parts, and also make sure that the pedal is depressed normally.

If third and fourth gears do not engage, the cause is often a malfunction of the synchronizers or clutch in these gears. The speeds will be difficult to engage if there is no oil. Failure or wear of the gear selector mechanism will prevent the transmission from operating normally. Often the cause is wear of the rods. It's also worth checking the springs. Repair involves disassembling and replacing worn or damaged spare parts - GAZ-53 spare parts, despite its age, can still be purchased.

Gears are flying out

This can happen for a number of reasons. The first one is one of the banal ones. If there is severe wear on the gearbox shift fork, then the gears will not engage completely - then they will fly out. Urgently! How much oil should I put in Q7 4.2? The second reason is significant wear of the gear seats on the secondary shaft. How much oil is in a Hyundai Accent engine? How much to fill? Often the gear itself wears out a lot. This is the cause of the malfunction. To restore the operation of the box, it will be enough to replace the failed elements.

Gearbox repair

In fact, it is not difficult to repair the box, but a professional will do it faster. Self-repair is also possible if spare parts are available. GAZ-53 is a very repairable car. Finding spare parts for it is now not a problem, and you can buy them in the markets at an affordable price. Often, repairing a unit can be expensive. In this case, you can save money by replacing the box with a used one. The modern automotive market offers a lot of options. It is only recommended to agree in advance on the possibility of return in case of malfunction.

The plant produced many transmissions for these cars. Therefore, finding a used unit will not be difficult. Prices for units are affordable. You can also install a transmission from a GAZ-63 truck. It is completely identical and interchangeable.

Story

The trucks, which were among the first to be assembled and designated “F”, were equipped with six-cylinder power units, as well as a rear axle from the GAZ-51 model. The transmission was also taken from this car, but they were previously modernized. It must be said that, if necessary, you can change the GAZ-53 gearbox to a GAZ-51. But such a replacement does not always make sense. The transmission that was installed on the GAZ-51 had different gear ratios and was created to work with lower-power engines.

The assembly of the GAZ-53F models was completed, and the GAZ-53A began to be produced instead. This model was equipped with a V8 engine, so to work with this unit, engineers had to modify the transmission and develop a new design for the rear drive axles.

Gearbox for GAZ 53

GAZ-53 is a famous Russian heavy-duty vehicle. The first versions of the car became available in the early 1960s. This medium-duty vehicle has become widespread in the agricultural sector.

The main advantage of this technique is that it has high resistance to the loads that fall on it. Considering this, it is important to use it in extreme conditions. A trailer can be installed on the machine. The maximum permissible weight of a towed trailer can exceed 3 tons. This truck is easy to maintain. Decent speed is generated thanks to the gearbox.

The car is rear-wheel drive. In this case, the power plant and transmission are located in the front part. A manual gearbox with a dry single-plate clutch is installed as standard.

GAZ 53 box design

The gearbox on the GAZ 53 is one of the constituent components of the automotive system. On the latest generations of cars, the carrying capacity has reached 4.5 tons. The manufacturer chose a 3-way manual transmission (4 stages) as the transmission. The weight of the box is 56 kg. A number of GAZ-53 modifications support the installation of a transfer case.

The gearbox includes the input shaft. It communicates with the clutch driven disc. There are no differences between the input shaft and the GAZ 51 and 52 gearboxes. The transmission system includes a cardan drive. The cardan ensures the transmission of torque between transmission mechanisms. The cardan transmission consists of an intermediate and main shaft. In this case, the intermediate shaft communicates with the gearbox.

Scheme of the structure of the GAZ 53 gearbox

The secondary shaft is mounted on a roller and ball bearing. The clutch is installed in the crankcase. The sleeve is securely fixed to the shaft. A gearbox is installed in the rear axle housing. There is a gear differential (on the spider). The camshaft is made of steel and the gear is made of electrically insulating structural material.

The gear ratios for GAZ 53 are as follows: I (6.55), II (3.09), III (1.71), IV (1.00).

Thus, the GAZ-53 is a massive truck that has excellent technical equipment. The mechanical 4-speed gearbox is characterized by long-term performance.

Characteristics of faults with the gearbox

We list the main faults when it is advisable to repair the GAZ 53 gearbox.

Noise when the speed box is operating. In some cases, this may be due to wear of parts installed in the transmission system. As a rule, this happens after a long and active use of the vehicle. Sometimes tightening loose mechanisms can solve the problem. It is necessary to diagnose the car if noise begins to be noted when the speed limit changes.

The next problem is difficult gear shifting. There may be several reasons for this:

not adjusted clutch;
wear of gearbox components.

In addition to this, the spline connections of the coupling should be checked. All worn or faulty parts must be replaced. It is always necessary to make a choice in favor of proven products.

If 2nd and 3rd gears slip out, you need to check the synchronizers. Excessive heating of its housing helps reduce the life of the gearbox on the GAZ 53.

The gearbox on a GAZ 53 should be checked if the driver detects oil leakage through the seals. During long-term operation of the machine, you should check the play in the spline joints and the reliability of the bracket fastening.

Thus, breakdowns of the speed box are accompanied by noise and extraneous sounds. Maintenance must be carried out according to the schedule established by the vehicle manufacturer.

Features of repair work

Why does the gearbox fail? As a rule, malfunctions with the high-speed gearbox are a consequence not only of the natural wear and tear of its component parts, but also due to non-compliance with the rules of its operation.

During a major overhaul, it may be necessary to repair the input shaft of the GAZ 53 gearbox. This shaft includes a gear block. The design of the part itself is non-separable. In good condition, the shaft should not have external damage or roughness.

The gearbox input shaft takes on high loads. That is why this spare part was made of durable material. In some cases, professional metalworking and mechanical processing can help restore this part. Shafts and cardans should be periodically cleaned of dirt.

To remove the gearbox from the car, you need to drive the car into an inspection hole, remove the control lever, cover, and drain the oil. Next, disconnect the handbrake lever, rod, and unscrew the fastening bolts. Finally, the GAZ gearbox is disconnected from the clutch housing.

It is recommended to fill the gearbox with TAD-17 transmission fluid. As a rule, a gearbox requires 3 liters. It is recommended to replace every 50,000 km.
