MAINTENANCE AND REPAIR OF GMP U 35.615 (Amkodor)

LLC "Spetsdorservice" offers high-quality and fast repair of GMP U36.615, assistance in determining the malfunction, full diagnostics and replacement of faulty parts of the gearbox. For the full-fledged operation of the Amkodor loader, it is necessary to monitor the state of its main working part - the gearbox U 36 615. It is necessary to monitor the condition of parts and mechanisms, the inclusion of the necessary transmission in these conditions, the operation of the turbine.

From this article you will learn about the reasons for the malfunction of the GMP U35.615, as well as the possibility of repairing parts that are out of order. The article is illustrated with illustrative examples of parts and recommendations for replacement / repair and can serve as an instruction for the operation of the U35.615 gearbox.

Causes of breakdowns of torque converters GMKP U35.615

In U35.615 gearboxes for Amkodor, I-20 oil is used to transfer torque energy from the engine to the gearbox, so its correct operation is of great importance. It is important that the oil does not overheat and clog, does not exceed a certain level and pressure.

For example, the pressure must be maintained at a level not lower than atmospheric. The turbine is protected from too high or low pressure by a regulating valve, which ensures the correct operation of the U35.615 TGD-340A torque converter

To avoid overheating the oil, you should carefully monitor the change in speed, for example, during a long idle period with the ignition on, the torque energy is converted into heat and the liquid heats up.

The oil level in the U35.615 turbine (GT-1709900) also affects overheating and, as a result, the power drop. The formation of gas bubbles in the oil will reduce the performance of the transmission.

Slipping is the state of the turbine of the Amkodor U-35.615 gearbox in which the PZ-40 or NSh pump continues to rotate, and the turbine remains in place.

In this case, the hydraulic transmission U35.615 is in the "FORWARD" or "REVERSE" mode (but not NEUTRAL) and a large load is applied, or a breakage of the blades leads to the machine stopping when the engine continues to work.

Damage assessment

GMP U35-615 is the soul of your loader. In case of any malfunction of parts, the possibility of reuse should be objectively assessed, taking into account the daily maintenance and operating conditions of the Amkodor GMP.

GMP (hydromechanical transmission) is used for installation in transmissions of machines of the timber industry complex, as well as municipal, earth-moving, agricultural, road-building equipment. It is used to transfer a power flow within 100 kW, coming from the engine to the drive of the driving axles. In this case, the torque and rotational frequency are transformed in direction and magnitude.

GMF is used to provide:

· Changes of gears under the influence of load, as well as disconnection of the engine from the leading wheelset (neutral gear);

· Smooth change of speed and traction force in automatic mode on each of the gears within the limits of the transformation ratio, as well as the gear ratio of the hydraulic transformer.

Repair of GMP Amkodor includes a hydraulic system, as well as hydraulic and mechanical transformers.

· A hydraulic transformer that transfers mechanical energy through a circulating fluid flow. It is able to automatically smoothly change the transmitted torque within certain limits, adjusting the parameter depending on the external load. It is used to achieve stable operation of the engine when the external load drops or increases, as well as to minimize the effect of dynamic loads. GT is also used to improve the durability of the transmission and engine.

· The mechanical converter is used as a unit that transforms the rotational frequency and torque in direction and magnitude. The change is made using constant mesh gears for a certain amount - from gear to gear. The gears are regulated within a certain range under the load of the clutches, and when changing from one range to another, under the load of the gear clutch.

Powering the hydraulic transformer and controlling the clutches in the hydromechanical transmission requires equipping the hydraulic system, located both on the GMF itself and outside it.

Today, over a long production period, among manufacturers of domestic special equipment (as well as special equipment manufactured in the CIS countries) - motor graders, front loaders, forklifts or other self-propelled vehicles - the most common transmission model is hydromechanical transmission U35.615, U35.605 and gearbox U35.606.

The indicated transmission models, although they are produced at different factories, differ little in principle from each other. They have almost complete interchangeability, and the distinctive features are more related not to different models by manufacturers, but to modifications in terms of applicability.

Hydromechanical Gearbox - GMKP U35.605 and Gearbox - Gearbox U35.606 produced in the Republic of Poland until the mid-90s (currently out of production); GMKP were used on all front-end loaders with a carrying capacity of 2.0 to 4.5 tons, as well as on motor graders and Rybinsk rollers; KPP U35.606 and KP-13.42 were used only on motor graders;

Hydromechanical Transmission - GMP U35.615 produced in various modifications at Amkodor OJSC (Republic of Belarus), Kalugaputmash OJSC and Murommashzavod OJSC (discontinued at both enterprises due to financial difficulties); GMP U35.615 are used on front-end loaders.

Hydromechanical transmission - this name is used in everyday life or in unofficial literature.

The above terms are synonymous and mean essentially the same thing.

Our company produces a full range of spare parts for these transmissions and supplies consumables.

Having its own technical center, Agrodorservice is actively engaged in overhaul of hydromechanical transmissions, performing work in the shortest possible time and with high quality. The unique test bench allows testing of hydromechanical transmissions in dynamic and “stop” modes.

The use of high-quality spare parts during transmission repair, production culture during assembly and careful performance of acceptance tests allow us to give a guarantee for the work performed.

The actual repair of the transmission with testing and delivery of finished products to the warehouse takes about 5 days.

When installing the GMKP on the machine, the mechanic must check the connection and serviceability of the pressure sensors (there are 2 of them in the hydraulic system of the GMKP), the temperature sensor, check the level and quality of hydraulic oil, the operability and flow sections of the cooling radiator of the hydraulic system of the GMK.After the final check of the connection and serviceability of all external elements and cardan shafts, start the machine for the first time with the installed hydromechanical transmission. It is not permissible to operate the GMKP in the presence of extraneous noise, overheating of the hydraulic fluid, with reduced or increased pressure in the hydraulic system, lack or low level of hydraulic oil, a clogged cooling radiator, without a filter or with an old filter, as well as cardan shafts that have a large imbalance, a faulty gearbox power take-off (POM), or any other malfunctions.

Operation of the transmission must be carried out in strict compliance with the requirements set forth in the GMKP operating manual supplied with the machine documentation.

The gearbox is one of the most important parts of a car, and its importance cannot be overemphasized. The gearbox determines the performance and speed of the vehicle, so it requires serious maintenance and close attention. But with all the care, gearboxes often break down, so you have to think about repairs.

The most common are the K-701 checkpoint, the K-702 checkpoint and the K-703 checkpoint, but they often have some minor problems. They can be easily eliminated by disassembling the gearbox yourself and making a defect. But it is important to know what you are doing, because in inexperienced hands, even simple disassembly of the gearbox can lead to serious damage. Therefore, first read the relevant literature or consult with knowledgeable people, and only then repair the checkpoint.

The K-144 gearbox model looks more reliable in this regard, as well as transmission options from another series - T-130, T-150 and T-170. Of this list, the most fragile is the T-130, which has a fairly wide list of frequent damage. For example, when the clutch is engaged, the gear may not engage, or while the engine is running, the gear may be randomly disengaged. In addition, the T-130 suffers from overheating of the oil and difficult disengagement of gears, as well as knocking and noise. That is why the T-150 and T-170 were introduced, which have much fewer potential breakdowns, and their malfunctions occur much less often.

Special attention should be paid to GMF, or hydromechanical transmissions. The most common and generic name for these is automatic transmission. It is worth highlighting such models as GMP U35.605, U35.607, U35.615, which are among the most popular and well-known, as well as reliable. In the first model, a little more often than in others, it is necessary to repair fluid couplings and change bearings, and in the second, to change the oil, while in the U35.615 it is difficult to highlight any specific shortcomings.

GMP, unlike a conventional checkpoint, is not recommended to repair yourself - it is better to leave this business to professionals who will carry out repairs quickly and efficiently, while the price for such repairs will not seem overpriced to you.

And even if you have an ordinary checkpoint, then you should not repair it without the necessary knowledge in this area - it is better to entrust this business to professionals or carefully study the necessary information in order to be confident in your abilities. And only then can the checkpoint be repaired, preferably in the presence of a knowledgeable comrade.

The power take-off gearbox takes over the main load when working with heavy Amkodor equipment. In case of improper operation of equipment or its use in difficult conditions, POM repair will inevitably be required. The problem is not so much the fact of a breakdown of the power take-off gearbox, which can be replaced, but the consequences of operating equipment with a faulty gearbox.
