Adjusting the preload of the pinion bearings on the ZIL-5301 vehicle

The tapered roller bearings of the pinion must be adjusted with a preload by selecting adjusting washers 9, of which two pieces are installed.

Brake valve of the ZIL-5301 parking brake system

The valve can be installed to the right of the driver's seat or on the dashboard

Check the angular free play of the steering wheel with the engine idling, shaking the steering wheel until the steering wheels begin to turn

All parts of the boost corrector (BC) to be assembled must be clean, and the rubbing surfaces must be lubricated with engine oil

Wiping parts with a wiping material is not allowed.

ZIL-5301 engine coolant pump

The design of the liquid pump is shown in the figure.

The liquid pump body as an assembly must be tested with water under a pressure of 0.2±0.01 MPa for 2 min. In this case, no leaks or drops are allowed.

Installing the steering gear of the ZIL-5301 vehicle

Install the steering gear with hydraulic booster on the frame using the KZ-0352 device and secure it with bolts

Adjusting the fuel supply ZIL-5301

To adjust the amount and uniformity of fuel supply by the pump sections, do the following.

Before adjusting the pump for uniformity and amount of fuel supply by each section, check:

Assembly of the 4UTNI-T-1111005-50 high-pressure fuel pump for the ZIL-5301 vehicle

Before assembly, the low-pressure cavity of the pump must be flushed with diesel fuel under a pressure of 1.8-2.0 MPa. filtered M10G2 motor oil should be used to lubricate the pump and regulator parts

Adjusting the contact patch in the main transmission gears of the ZIL-5301

After adjusting the main transmission bearings, it is necessary to check the engagement of the teeth of the driving and driven bevel gears (on the paint on the contact patch) and, if necessary, adjust the engagement and set the required gap between the teeth.

The ABS modulator is designed to control the air supply to the pneumatic chambers of the main cylinders

Front suspension - dependent, leaf spring, attached to the frame with elastic hinges.

Guide apparatus and elastic elements - longitudinally located asymmetrical leaf springs

An electro-pneumatic door closing drive is used on buses and special vehicles. The electrical diagram of the drive is shown below

Possible malfunctions of ZIL-5301 brakes

If, when you press the brake pedal, you feel a sharp braking of the front brake with it being pulled to the side, then the front wheel pads have clearly worn out completely, and because of this, the brake disc is worn out

Usually vibration on ZIL-5301 is felt most at a speed of 60-70 km/h

If vibration occurs when driving ZIL-5301:

Reinforced version of the ZIL-5301 clutch

Since April 2001, a reinforced version of the clutch has been installed on vehicles.

The damper part of the driven disk has been reinforced: the damper springs are vulcanized with rubber and look like a rubber cylinder

Assembly and installation of the ZIL-5301 cardan transmission

Before installation on the vehicle, the cardan transmission must be fully assembled

Laying the D-245 crankshaft

Before assembly, each crankshaft must be checked on a magnetic or ultrasonic flaw detector for the absence of micro and macro cracks; and also for compliance of the selected set of main bearing shells with the size of the main journals
