Cars UAZ (loaf) have the most capacious body. The case of the machine is made of durable material. The vehicle is equipped with security systems, a stogious power unit that is capable of developing the capacity of more than 100 horsepower, the transmission system.
All-wheel drive cargo-passenger UAZ, which has increased permeability, began to produce serially at the Ulyanovsk Automobile Plant in the mid-1960s.
The components of transmissions of the UAZ.
On the machines of the OAZ - 452 family of a new sample there is a mechanical gearbox (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. The filler cork is 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. A new liquid must be poured to the oil-free hole in 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 vehicle variant is 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, brake levers are subject to me. 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. When self-assembling, the driver may have difficulties with the installation of the primary shaft into the clutch system. With this process, you must 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.
OJSC "Arzamas Machine-Building Plant" is a city-forming enterprise Arzamas and one of the largest enterprises of the Nizhny Novgorod industry. Founded in 1972 as an Arzamas plant of automotive 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. To date, this is a plant with a specialization in the production of armored personnel carriers of BTR-80, BTR-80A, BTR-80K, Bram-K, UNH, modernized by BTR-60PBM, BTR-70M, BRDM-2A, special vehicles "Vodnik", " Tiger ", as well as on the manufacture of parts and components to cars produced by JSC 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 the rear - 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" a lot of useful tips and stories about ARCP are collected.
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.
Box gear UAZ
Many owners of domestic cars often face faults in the gearbox on the UAZ. But the Russian man works so that he always prefers to postpone the repair for later. As a result, the lever PPC UAZ is often starting to flure.
From the transmission constantly comes the root of the gear, and sometimes the box and stops responding at all. It's time to do it with repair or replacement to a more perfect, for example, PPC ADS or PPP "Daimos".
Five-speed gearbox for UAZ Patriot
The Russian organization "AVTODOMETAL-SERVICE" (ADM) specializes in the production of CAT for UAZ cars. The 5-speed PPC "ADS Expert" comes to the Ulyanovsky Auto Plant, where the current models of domestic SUVs are equipped. It is a one-piece carter and synchronized on all transmissions of the front turn.
The gearbox is equipped with both sprinkle and a dispensing box. Modern boxes "ADS Expert" have the following features.
- By increasing the length of the gear shift lever, the box mechanisms function more smoothly.
- The recycled distribution frame rod is equipped with a brake back brake mounting bracket, which makes it much easier to collect gearbox in the installation process.
- The overall gear scheme and the selected gear change device have changed somewhat. This made it possible to prevent oil leakage and secure the PPC cover from the penetration of the Earth and Water.
- A special sensor is mounted in the design, which ensures uninterrupted nutrition of the rear lights.
- The transfer of the gearbox camera hole is shifted by 2 cm below. This is done to improve the circulation of oil inside the CAT. His getting into the dispensing box is completely excluded.
In addition to the ADS Expert, in 2013, an improved version of the transmission from the Daimos company, based on electrical control, was developed for UAZ Patriot. This made it possible to completely eliminate the use of the RCP lever. Instead, a special washer is built in. The rear drive shaft has changed: it has shortened and removed the intermediate backup.
Repair of gearbox
The 5-speed PPC "Daimos" is suitable for other UAZ models, including a symbir, Hunter and UAZ-3160.
To install the gearbox of a new sample on UAZ Hunter, you will need to change the germ hatch bodies for more modern. The remaining 2 auto models will require a small upgrades, because in the floor it is necessary to cut a hole for the gearbox lever.
When carrying out installation work, you need qualified assistance, so it is recommended to entrust the transfer of the transmission licensed one hundred.
If you want to independently replace some gearbox details, use the instructions of the full disassembly and the CAT assembly on the UAZ. In this case, the repair can be carried out without the use of lift and third-party help.
Required tools and preparatory work
Disassembly of the gearbox UAZ will require the following tools and materials:
- a set of horn and end keys of 10 to 36 sizes;
- a special wrench for tightening the stovered nuts (you can use cycling);
- set of crosses and flat screwdrivers;
- service-key with a straight and curved end (passage);
- copper synchronizer or stem for work with gears;
- a small segment of a pipe made of metal to hold the keys when screwing nuts in hard-to-reach places;
- chisel-core and heavy hammer;
- set of gaskets for CAT UAZ;
- high-quality sealant to be used to install pads.
Selecting the set of keys, it is important that they are as compact and thin. Most attachments are in an uncomfortable position, so the competent choice of keys will save you time and nerves.
The gaskets are desirable to take for the current model, but if your car is an old sample, for example, with a BEA 3303 gearbox, any set for the past generation of cars will suit.
If there is a need to update the gearbox, you will need to buy special sets of hardware for the checkpoint and dispensing box. With the second set there may be problems because it is not so easy to find in auto parts stores.
The scheme of the PPC UAZ has its own characteristics of the dispensing box and the checkpoint. Of course, this type of construction gives a huge advantage, but it is hard to remove it yourself, because the node weighs about 80 kg. Without third-party help, you will have to raise a car through a manual winch. At the same time, it is necessary to take care that she has a reliable support. For example, a metal frame or a durable beam ceiling. The design should easily withstand the weight of your car.
Before starting work, you need to install the car on a uniform surface. Then it is necessary to drain the oil from the checkpoint and the transfer box. Despite the general feed system, each of them has separate plugs for drain. While the lubricant follows, you can dismantle the front seats, dashboard and 2 hatches that are located on the bottom of the body. After the oil stalks to the end, you need to return the plots in place.
Dismantling a node that binds the checkpoint and distribution
Disassembled box of UAZ
Start with the development of the frame crossbar, which is located under the system of manual brake. Remove the front cardan, disconnecting it from the dispensing box flanges. Easy this process will help shut down the front-line bridge clutch. Rear cardan needs to be dismantled from the top side of the body.
The clutch system must be dismantled, it should be started with the spout of the fastener of the valve shaft slots, while the hose is pushed inside the bell. Split 4 bolts that hold the clutch plug overlap, and remove the spring. Then unscrew the functional cylinder controller and pull the plug.
The dispensing box and gearbox will need to wrap a cable or rope and leave for a while. We will develop custods and hardware holders on the bell. This is done gradually and evenly. It is possible to completely spin bolts and nuts, only if the box moved away from the bell slightly. It is recommended to make a temporary support for the machine of the machine using a jack, otherwise its lower part will hang and will interfere. After successfully disconnecting the gearbox, you can completely remove it.
Worn parts inside the bell are best replaced with new ones. In particular, it concerns the studs, since their carving is very quickly stepping.
Where to start disassembly gearbox
Remove the hand brake lever so that it does not interfere. After that, unlock hardware connecting the gearbox and dispensing box. Most often it is not possible to make one movement, as the details are fastened with sealant. We have to be carefully hit by the node to disconnect them. It is very important to followpacts, after separation, nothing should be lost. It is advisable to put them in one container and postpone to the assembly.
The gearbox and dispensing box must be viewed for worn items. To disassemble these details, you need to try as you should try, because bolts and nuts are in hard-to-reach places.
In the primary shaft there is a roller bearing, which does not have a clip, so in most cases it is scattered when dismantling. After its assembly, you need to pay attention to how the last video is located. If the roller is easily entered, it will have to be changed, as this testifies to the wear of the part.
