We replace the oil in the gearbox after 20-30 thousand kilometers.
We change the oil after the trip, while it is warmed up and has increased fluidity
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
The lubrication system is combined, with oil supplied to the rubbing surfaces under pressure and splashing and automatic control of the oil temperature by a thermal valve
Replacing the cylinder head gasket of the ZMZ-405, -406 GAZ-2705 engine
The cylinder head gasket is replaced if it is damaged
Checking the level and adding fluid to the power steering reservoir
The reservoir is located on the left side of the engine compartment, next to the washer reservoir
Removing the sliding door and disassembling its moving mechanism
We work together or three, as the door is heavy
The vehicle's on-board circuit (except the starter circuit) is powered through two fuses
The power steering pump is removed for replacement or repair
Emerging defects in the hydraulic steering pump:
The engine must be thoroughly cleaned of dirt before disassembly
Replacing wheel bearings and axle cuffs
Release the handbrake by placing stops under the front wheels
Replacement of chains and gears of the gas distribution mechanism ZMZ 406 GAZ-2705
You will need: a 6-point hex key, 12-point, 13-point, 14-point sockets, a small chisel, a hammer
The ignition system - battery-operated, contactless - consists of an ignition coil, a switch, an ignition distributor sensor, spark plugs, spark plug tips, low and high voltage wires. The ignition system diagram is shown in the car electrical equipment diagram
The cylinder head can be removed with the intake pipe and exhaust manifold. If the cylinder head is removed from an engine installed on a car, you must first perform the following operations:
- - drain the liquid from the cooling system;
Adjustment of the steering mechanism is necessary when the vehicle's directional stability is low at high speed (you can't feel the steering wheel at high speed)
The cylinder block is cast from gray cast iron and is made in the form of a monoblock with the crankcase part lowered below the axis of the crankshaft
The crankshaft is cast from high-strength cast iron, five-bearing, has eight counterweights for better unloading of the supports
