Removal and installation of the engine

Before removal of the engine it is necessary to reduce pressure in system of fuel submission. For this purpose disconnect shoe twist of electric pump wires from twist of wires of injection system, start the engine, give it to work up to a stop, and then switch starter for 3 seconds for alignment of pressure in pipelines.

Detach a wire from the plug «minus» of the storage battery. Remove the air filter; unscrew a nut fastening the central injection unit and tack on a cover to the cylinder head, disconnecting from the filter hoses. Disconnect wires from injectors and close aperture of the central injection unit with the technological muffle.

Disconnect hose lead and drain the fuel from pipes on the engine. Close an aperture of the pipes and hoses to prevent them from dirt and the fuel leakage. Disconnect a cable of a drive throttle shields from the unit central injection and from an arm on an inlet pipe.

Disconnect vacuum hoses going to absorber and the gauge of absolute pressure from the central injection unit, and also to hose of crankcase ventilation system of the engine. Disconnect wires from all devices of system injection, established on the engine. The removal of the engine is carried out regularly. The installation of the engine is carried out in the order, opposite to removal. After installation adjust a drive of an accelerator and check up the system injection work, as is specified in the repair Manual of central fuel injection system.

Steering system

The mechanism for transmitting the rotary motion of the steering wheel to the steering-gear arm is arranged in the steering-gear case. It is bolted to the frame. In case of a frameless construction, it is attached to a member of the body.

Many motor vehicles, especially passenger cars, are now equipped with the rack-and-pinion steering. It consists of a straight-guided rack arranged at right angles to the driving direction, and a spur-gear pinion, attached to the end of the steering column, engaged with the rack.

This type of steering requires a minimum of joints; as a result, it features long service life and minimum steering slack. It is especially used in case of axleless front-wheel suspension. A friction shock absorber is arranged behind the spur-gear pinion to prevent road shocks from being transmitted to the steering wheel.

The operation of the steering system should not require great effort. The force to be applied to the steering wheel depends on the load of the front wheels. In some special cases it is required to assist the driver's effort by means of a pneumatic or hydraulic servo-steering unit. Generally, this unit consists of a compressed-air cylinder. By means of the piston rod, its piston acts directly on the steering control arm of the front axle, while turning of the steering wheel guides the front wheels and additionally actuates the control valves of the compressed-air cylinder. Thus, rather effortless steering is achieved.

Furthermore, adherence to the specified type pressure is important for a good steering. Besides, troubles in the steering system may be traced back to wrong position of the front wheels.
