Disconnect the wire from the negative terminal of the battery.

Remove the distributor cap.

During repairs, brake pads and wheel cylinders or parts included in them usually need to be replaced, for the removal of which there is no need to remove the entire brake mechanisms

UAZ vehicles are equipped with a four-cylinder, four-stroke, overhead valve, carburetor engine with liquid cooling

Maintenance of the K-126GU carburetor (for engines mod. 4178)

The K-126GU carburetor is used to complete the 4178 model engines, as an option to replace the K-151V carburetor

Carburetor K-131 (Fig. 1) - vertical, balanced, with falling flow, single-chamber, double-diffuser

Restore the normal size of the gaps between the pads and brake drums and reduce the pedal stroke using eccentrics, in which the hexagonal heads of the axles are brought out through the shield

If the amplifier fails, only the force from the driver’s foot is transmitted to the pistons of the master cylinder through pusher 33 (see Fig. 1), control valve, buffer 20 and rod 7

Fill the hydraulic drive only with special brake fluid according to the instructions in the lubrication table in the following order:

Motor power supply system diagrams are shown in Fig. 1, 2, 3.

The reliability and durability of the engine, as well as the dynamic performance and efficiency of the vehicle as a whole largely depend on the state of the power system.

Procedure for disassembling and assembling carburetors K-151V, K-151E and K-151U

Disassemble the carburetor in the following sequence:

Transmission of torque to the drive axles is carried out by open-type cardan shafts (Fig. 1), each of which has a movable spline connection and two cardan joints

The non-contact ignition system (Fig. 1) includes the following devices:

– sensor-distributor;

Removing and installing the engine on vehicles of the UAZ-31512 family

Before removing the engine from a vehicle mounted on an inspection ditch, do the following:

The durability of a repaired engine largely depends on its running-in on a stand and the operating mode of the car during the first 1000 km

The main defects of the cylinder head that can be eliminated by repair include: warping of the plane of contact with the cylinder block, wear of seats and valve guides

In the article we will consider possible malfunctions of the front axle of the UAZ-3151

The lubrication system diagram is shown in Fig. 1.

Repair of connecting rods comes down to replacing the upper head bushing and then processing it to fit a piston pin of a nominal size or to processing the bushing available in the connecting rod for a repair-size pin
