PPC UAZ 5-speed Ulyanovskaya scheme. PPC: The right choice for UAZ. Causes of damage

OJSC "Arzamassky machine-building factory"He is a city-forming enterprise Arzamas and one of the largest enterprises of the Nizhny Novgorod industry. Founded in 1972 as the Arzamas factory of automobile spare parts of the Gorky Association for the production of cars. For 35 years of its activities, the plant became the leading enterprise of the Russian Federation for the production of wheel armored vehicles. Today is the factory. with a specialization in the production of armored personnel carriers of BTR-80, BTR-80A, BTR-80K, Bram-K, UNH, upgraded by BTR-60PBM, BTR-70M, BRDM-2A, special vehicles "Vodnik", "Tiger", as well as Production of parts and assemblies to cars manufactured by OAO GAZ. It is part of the GAZ Group Holding.

Mechanical five-speed gearbox 31606-1700010 For UAZ cars, it has a peculiar shift algorithm. Rear - where there should be the second. And the fourth is on the place of the back. The idea to arrange the rear transmission opposite the first is not so bad: it will pretty help the driver trying to get out of the "ambush". Turning on rear transmission - without "fool protection", without blocking. Changing the transmission procedure requires a certain addiction.

Earlier for cars UAZ, the choice of gearboxes is reduced to two four-step versions. The first is synchronized only by the third and fourth transmission and more "cargo" selection of gear ratios, higher reliability due to a smaller number of parts, the design allows you to disassemble and collect the mechanism in the field. To switch gear, double clutch disclosure is required. The second four-stage gearbox, which appeared in 1989 and produced in parallel with the first, synchronized on all transmissions. These gearbox differ as follows - at an uninfined box the course of the lever when the first transmission is turned on is twice as long than for the rest of the steps. At synchronized all transmissions are "equal."

On the UAZ cars produced in our century, five-speed gearboxes began to appear. One family from Ulyanovsk and the second from Arzamas. PPC from Arzamas promised to become more reliable than the Ulyanovsk "5th protest" with the withdrawal crankcase of the fifth transmission. But a kind of algorithm for switching gear confuse drivers of unusual logic of work. Yes, and reviews about the reliability of the CAT from Arzamas (or just ARCP) Not the most pleasant. At the Specialized Forum "Weazbuka" collected many useful Soviets and stories about the ARCPP.

In the future, 5-step gearboxes "Dymos" from Korea began to install 5-speed gearboxes of Korea and 5-speed gearboxes of OJSC Avtodetal-Service appeared in different modifications.

Cars UAZ (loaf) have the most capacious body. The case of the machine is made of durable material. Vehicle is equipped with security systems, hardy force aggregatewhich is capable of developing the power of more than 100 horse power, Transmission system.

All-wheel drive cargo-passenger uazik, which has increased patency, it was serially produced at the Ulyanovsk Automobile Plant in the mid-1960s.

The components of transmissions of the UAZ.

On the machines of the UAZ - 452 of the new sample present mechanical PPC (four-stage). Provide a lightweight transmission of inertial type synchronizers. The five-speed gearbox ADS is synchronized on all front turning transmissions.

On UAZ can be installed 5-MCAP DIMOS (DYMOS). This gearbox is distinguished by its reliability. The average resource of its work is 300,000 km run. Flashing plug Located in the middle of the box, drained below. They are possible to unscrew using a hex key. When the oil drops, a special container should be prepared. New liquid It is necessary to pour to the oil-free hole existing on the box. The probe allows you to accurately determine what the liquefit is flooded. An alternative to the probe can be a long nail. In order to prevent, every 15,000 km need to measure the oil level.

The presence of mechanics on this option vehicle Fully justified. Such a car is relevant to use the rough terrain, with off-road. In addition, it will not be tugging problems.

The gearbox has an external switch lever. The lever in the cockpit is freely moving both in parallel and perpendicular to its axis.

The machine is equipped with a handout box. In the design of the dispensing box on the UAZ 452: the trees of leading bridges, gears. All listed components details are in a cast-iron crankcase. Carter and cover are connected by nuts. Securely fastened in the shock shift rods.

There is a slot, bearings. There is a screw gear of the speedometer drive. On the bearings "loaf" recorded an intermediate shaft. On this box there are reliable gears with straight teeth.

Thus, the PPC on the UAZ 452 consists of a plurality of nodes and units. This node needs regular.

The need to diagnose gearboxes UAZ model 452

This vehicle necessarily shall be diagnosed if the control began to deteriorate, characteristic symptoms began to be heard when gear changes or transmission began to spontaneously change. A dispensing box of UAZ should be checked if the clutch of the wheels with the road has noticeably deteriorated, a hum of increasing noise occurs when it works.

During the passage, the wizard must check the system for leakage of oil, lubrication level. All worn items in the transmission system must be replaced with new ones. Also, the diagnosis implies the exercise of the lubrication of the axis of the levers, adjusting the forward thrust.

Planned diagnostics in the professional auto repair shop allows you to accurately determine the case of a challenge with a box, eliminate the existing problems at an early stage.

Causes of damage

As a rule, the need to replace the main component parts on the CAT occurs with their natural wear.

Causes of breakdowns

The main cause of the leakage of oil from the checkpoint is the presence of an increased level of fuel in the system. For PPC on UAZ, high-quality oil should be used. If the fluid does not have due quality, then due to this, characteristic noise from the box side can occur. When the synchronizer or its parts wear is always noted difficult to change the gear. Pay attention to the details of the switching mechanism. When deforming, the gears often marked the self-off of gears.

The process of removal of the checkpoint

Repair of the checkpoint on the UAZ 452 is quite possible to carry out their own hands. This requires:

• set of wrench keys, including the keys necessary for tightening nuts;
• screwdrivers;
• a hammer;
• chisel;
• pliers.

Algorithm dismantling.

The car should stand in a flat place. It is necessary to merge the oil from two boxes by unscrewing the plum plums. Next, the front seats are removed, the half of the hatch, the clutch shutdown plug, the transverse frame, the shift levers from the boxes.

Speedometer shaft, suspension supports in the chassis, levers brake system. As a result, access to the clutch can. It is fixed on the fastening nuts the box that must be unscrewed, then gently put forward the gearbox of the UAZ along with the transfer gearbox before the outlet of the flasteed shaft from the flywheel. To select the box, the driver will need an assistant.

The assembly of the CAT UAZ requires proper attention. For self-assembly The driver may have difficulties with the installation of the primary shaft into the clutch system. For this process It is necessary to actively move the box so that the shaft falls into the slot.

As soon as there was a disassembly on separate components, the box must be rinsed in kerosene, dry. All components spare parts are checked for integrity. First of all it concerns Carter, shafts. If the thread is damaged on the shaft, they must be replaced. The car seems dangerous to exploit if chips will be available on the gears.

Thus, timely produced repair of the PPC UAZ "Buanka" contributes to the extension of the resource of the box.

From 4-speed it is distinguished by the presence of synchronizers on all transmissions. The box has a much smoother switching. Improved dynamic characteristics. Auto is speeding up speed. Reduced general noise when working, due to which acoustic comfort improved, vibrations decreased. PPC UAZ 5-step ads relatively simple to repair. Thanks to the 5 transmissions and improve the engine operation, the fuel consumption was reduced by as 20%.

Having bought CPP UAZ 5-step ads you get example gearbox resource 300000 kmWhat is also higher than that of the predecessor. Also, the car will expand the speed range. The box is compatible with UAZ - 3303, 3741, 3962, 2206 with engines of the Ulyanovsk motor factory UMZ-4178, UMP-4213 (INS), UMP-4218.
