A feature of the ZMZ-40524 engine control system is:

We replace the brake disc if cracks or severe scuffing appears on its surfaces, as well as if it is worn to a thickness of less than 19 mm

Remove the steering column lining

Disconnect the wires from the brake light switch

We remove the brake cylinder for replacement, as well as to replace the cylinder repair kit

Removal and installation of the flywheel ZMZ 406 GAZ-2705

The flywheel is removed to replace the rear crankshaft oil seal, to replace it if the toothed rim used to start the engine with the starter is damaged, and to grind the surface under the clutch driven disc

Removing the fan belt

Loosen the belt tension (not shown in the photo), to do this, loosen the tightening of nut 1 and adjusting bolt 2 and turn bracket 3 with tension roller 4 to the engine cylinder block

On cars of the GAZelle family of different years of production and configurations, three combinations of instruments can be installed: the old model produced before 2003, the new model produced since 2003 for cars with engines ZMZ-4063, ZMZ-40522, UMZ-4215 and new production model since 2003 for cars with ZMZ-40524 and UMZ-4218 engines

The main brake cylinder with a two-section reservoir and a sensor for emergency drop in brake fluid level is attached to the vacuum booster

Replacing the cylinder head cover gasket ZMZ-406 GAZ-2705

Over time, during operation, the gasket under the engine head cover loses its elasticity and strength and oil leaks from under the cover

The main brake cylinder, with two sequential pistons 10 and 17 and a two-section reservoir 4 with sensor 6 for an emergency brake fluid level drop indicator, is attached to the cover of the vacuum booster

The car is equipped with two rectangular headlights with a halogen double-filament lamp AKG12-60+55-1, power 55/60 W (low/high beam) and an A12 side light lamp with power 4 W

• - clean all mating surfaces of the block from gaskets stuck and torn during disassembly;

When the force on the brake pedal increases, it is necessary to check the functionality of the vacuum booster

Steering column switches

The car uses two steering column switches mounted on the steering column.

On some vehicles, the sound signal is turned on by the turn signal and headlight switches, and on others - by the windshield wiper and washer switch

The pressure regulator is attached to the left frame side member

It adjusts the brake fluid pressure in the brake circuit of the rear wheels, depending on the vehicle load, which increases directional stability when braking
