You can buy and install the UAZ 5-speed ADS gearbox without making any changes to the vehicle design.
UAZ gearbox
Many owners domestic cars often encounter malfunctions in the gearbox on the UAZ. But a Russian person is built in such a way that he always prefers to postpone repairs until later. As a result, the UAZ gearshift lever often starts to junk.
From the transmission, the rumble of gears is constantly heard, and sometimes the box stops responding altogether. It's time to start repairing it or replacing it with a better one, for example, the ADS checkpoint or the Daimos checkpoint.
Five-speed gearbox for UAZ Patriot
The Russian organization Avtodetal-Service (ADS) specializes in the production of gearboxes for UAZ vehicles. 5-speed gearbox "ADS Expert" is supplied to Ulyanovsk Automobile Plant where current models of domestic SUVs are equipped with it. It is a one-piece crankcase and is synchronized in all forward gears.
The gearbox is completed with both spur and helical transfer case... Modern boxes "ADS Expert" have the following features.
- By increasing the length of the gear change lever, the gearbox mechanisms function more smoothly.
- Redesigned transfer case rod equipped with return spring mounting bracket hand brake, which makes it much easier to assemble the gearbox during installation.
- The general gearbox layout and the selective gear changer have changed somewhat. This made it possible to prevent oil leakage and protect the gearbox sheathing from the penetration of earth and water.
- A special sensor is mounted in the design, which provides uninterrupted power supply to the rear lights.
- The filler opening of the transmission chamber is 2 cm lower. This is done to improve the circulation of oil inside the gearbox. Its getting into the transfer case is completely excluded.
In addition to ADS Expert, in 2013 an improved version of the gearbox from Daimos, based on electric 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 has also changed cardan shaft: it was shortened and the intermediate support removed.
Gearbox repair
5-speed gearbox "Daimos" is also suitable for other UAZ models, including Simbir, Hunter and UAZ-3160.
To install a gearbox of a new model on the UAZ Hunter, it will be necessary to change the floor hatches of the car body to more modern ones. The other 2 car models will require a little modernization, since it is necessary to cut a hole in the floor for the gearshift lever.
During the installation work, qualified assistance will be needed, therefore it is recommended to entrust the replacement of the gearbox to a licensed service station.
If you want to replace some parts of the gearbox yourself, use the instructions for complete disassembly and assembly of the gearbox for UAZ. In this case, the repair can be carried out without the use of a lift and outside help.
Necessary tools and preparatory work
Dismantling the UAZ gearbox will require the following tools and materials:
- a set of open-end and socket wrenches from 10 to 36;
- a special wrench for tightening the flat nuts (you can use a bicycle one);
- a set of Phillips and flathead screwdrivers;
- service wrench with straight and curved end (pliers);
- copper synchronizer or rod for working with gears;
- a small piece of metal pipe for holding keys when tightening nuts in hard-to-reach places;
- core chisel and heavy hammer;
- a set of gaskets for the UAZ gearbox;
- quality sealant that will be used to install the gaskets.
When choosing a set of keys, it is important that they are as compact and thin as possible. Most fasteners are in an awkward position for dismantling, so choosing the right keys will save you time and hassle.
It is advisable to take gaskets for the current model, but if your car is of an old model, for example, with a UAZ 3303 gearbox, any set for the previous generation of cars will do.
If there is a need to update the gearbox, you will need to buy special sets of hardware for the gearbox and transfer case. The second set can be problematic as it is not easy to find in auto parts stores.
The scheme of the UAZ gearbox has its own peculiarities of connecting the transfer case and the gearbox. Of course, this type of construction provides a huge advantage, but it is difficult to remove it yourself, since the unit weighs about 80 kg. Without outside help, you will have to lift the car with a hand winch. In this case, you need to make sure that she has reliable support. For example, a metal frame or a sturdy beamed ceiling. The structure must be able to easily support the weight of your vehicle.
Before starting work, place the machine on a level surface. Then it is necessary to drain the oil from the gearbox and transfer case. In spite of common system feed, each has separate drain plugs. While the grease is running out, you can remove the front seats, dashboard and 2 hatches, which are located at the bottom of the body. After the oil has drained to the end, you need to put the plugs back in place.
Dismantling of the unit connecting the checkpoint and the transfer case
Disassembled box UAZ
Begin by unscrewing the frame crossbar, which is located under the handbrake system. Dismantle the front universal joint by disconnecting it from the transfer case flanges. Disconnecting the front axle couplings will help facilitate this process. The rear universal joint must be removed from the upper side of the body.
The clutch system must be dismantled, you should start by untwisting the fasteners of the input shaft splines, while the hose is pushed into the bell. Loosen the 4 bolts that hold the clutch fork trim and remove the spring. Then unscrew the function cylinder controller and remove the plug.
The transfer case and gearbox will need to be well wrapped with a cable or rope and left for a while. Unscrew the pillow mounts and hardware holding the gearbox on the bell. This is done gradually and evenly. You can completely unscrew the bolts and nuts only if the box has moved slightly away from the bell. It is recommended to make temporary support for the machine motor using a jack, otherwise its lower part will hang and interfere. After successfully disconnecting the transmission, you can remove it completely.
It is best to replace worn parts inside the bell with new ones. This is especially true for studs, as their threads grind off very quickly.
Where to start dismantling the checkpoint
Dismantle the handbrake lever so that it does not interfere. After that, unwind the hardware connecting the checkpoint and the transfer case. Most often, this cannot be done in one motion, since the parts are held together with a sealant. We'll have to hit the knot well to sever them. It is very important to keep an eye on the spare parts, after disconnecting nothing should be lost. It is advisable to place them in one container and set aside until assembly.
The transmission and transfer case should be inspected for worn parts. To disassemble these parts, you need to try hard, since the bolts and nuts are in hard-to-reach places.
The input shaft has a roller bearing that has no cage, so in most cases it crumbles when dismantled. After assembling it, you need to pay attention to how the last video is placed. If the roller enters easily, it will have to be replaced, as this indicates wear on the part.
UAZ cars (loaf) have the most capacious body. The body of the machine is made of durable material. The vehicle is equipped with security systems, durable power unit, which is capable of developing a power of more than 100 Horse power, transmission system.
All-wheel drive passenger-and-freight UAZ, which has increased cross-country ability, began to be mass-produced at the Ulyanovsk Automobile Plant in the mid-1960s.
UAZ transmission components
On machines of the UAZ - 452 family of a new model there is manual gearbox(four-stage). Synchronizers of the inertial type provide easy shifting of gears. The five-speed ADS gearbox is synchronized in all forward gears.
A 5-speed manual transmission Daimos (DYMOS) can be installed on the UAZ. This transmission is distinguished by its reliability. The average resource of its work is 300,000 km of run. Filler plug located in the middle of the box, drain from the bottom. It seems possible to unscrew them with a hex wrench. When the oil is drained, a special container should be prepared. New fluid must be filled up to the level of the oil filler hole on the box. The dipstick allows you to accurately determine to what mark the liquid is poured. An alternative to the stylus is a long nail. For preventive purposes, it is necessary to measure the oil level every 15,000 km.
The presence of mechanics on this option vehicle fully justified. It is important to use such a car on rough terrain, off-road. In addition, there will be no towing problems.
The gearbox has external shift levers. The lever in the cab moves freely both parallel and perpendicular to its axis.
The machine is equipped with a transfer case. In the design of the transfer case on the UAZ 452: drive axle shafts, gears. All of the listed components are located in a cast iron crankcase. The crankcase and cover are connected with nuts. The shift fork rods are securely fixed in the cover.
There is a slot, bearings. There is a helical gear wheel for the speedometer drive. The intermediate shaft is fixed on the bearings of the "loaf". This box contains reliable straight-toothed gears.
Thus, the gearbox on the UAZ 452 consists of many components and assemblies. This unit needs regular maintenance.
The need for diagnostics of the UAZ model 452 gearbox
This vehicle must be diagnosed if the control began to deteriorate, characteristic squeaks were heard, when a gear change occurs or the gear began to spontaneously change. The transfer case of the UAZ should be checked if the adhesion of the wheels to the road has noticeably deteriorated, a hum began to appear, and a growing noise during its operation.
During the passage of MOT, the masters must check the system for oil leaks, the level of lubrication. All worn parts in the transmission system must be replaced with new ones. Also, diagnostics involves the implementation of lubrication of the axis of the levers, adjustment of the front rods.
Routine diagnostics in a professional auto repair shop allows you to accurately determine the existing nature of the problem with the box, to eliminate existing problems at an early stage.
Causes of breakdowns
As a rule, the need to replace the main components at the checkpoint arises with their natural wear and tear.
Causes of gearbox breakdowns
The main reason for oil leakage from the gearbox is the presence of an increased fuel level in the system. For the checkpoint on the UAZ, use quality oil... If the liquid is not of the proper quality, then this may cause characteristic noises from the side of the box. When the synchronizer or its parts are worn out, a difficult gear change is always noted. Pay attention to the details of the switching mechanism. When the teeth of the gears are deformed, self-switching of gears is often noted.
Gearbox removal process
It is quite possible to carry out repair of the checkpoint on the UAZ 452 with your own hands. This requires:
- a set of wrenches, including the wrenches needed to tighten the nuts;
- screwdrivers;
- hammer;
- chisel;
- pliers.
Dismantling algorithm.
The vehicle must be on level ground. It is necessary to drain the oil from the two boxes by unscrewing the drain plugs. Next, the front seats, the hatch halves, the clutch release fork, the transverse frame, the gearshift levers from the boxes are removed.
Removable speedometer shaft, suspension mounts in the chassis, levers brake system... As a result, the outlet to the clutch housing is opened. The box is fixed on it with fastening nuts, which must be unscrewed, then the UAZ gearbox is gently pulled out together with transfer case before the splined shaft exits the flywheel. The driver will need an assistant to remove the box.
Assembling the UAZ gearbox requires proper attention. When self-assembling, the driver may have difficulties with installing the input shaft into the clutch system. During this process, it is necessary to actively move the box so that the shaft falls into the splines.
As soon as the disassembly into separate component parts has taken place, the box must be rinsed in kerosene and dried. All component parts are checked for integrity. First of all, this applies to the crankcase, shafts. If the threads on the shafts are damaged, they must be replaced. The machine is considered dangerous to operate if the gears are chipped.
Thus, timely repair of the UAZ “loaf” checkpoint helps to extend the resource of the box.
