Removal and disassembly of the ZIL-5301 diesel engine
To dismantle the power unit, it is recommended to install the bus on an inspection pit, above which there is a lifting device

The ZIL-5301 vehicle with division along the sides uses a flangeless two-cavity brake chamber, designed to act on the master brake cylinder and installed together with it on a bracket on the front panel of the cabin under the hood of the vehicle

Wheel speed sensor and ABS electronic unit ZIL-5301
Wheel speed sensors are designed to determine the angular velocity of the wheels and transmit a signal to the ABS electronic unit

ZIL vehicles and their modifications are equipped with a mechanical five-speed gearbox with synchronizers (Fig. 1).

The pressure regulator (Fig. 1) is designed for automatic regulation of pressure in the pneumatic system within 0.65 - 0.8 MPa, as well as for protecting pneumatic drive units from oil contamination and excessive pressure increase in the event of failure of the regulating device

The cylinder head is a cast iron casting, in the internal cavities of which there are inlet and outlet channels closed by valves

Installing the cylinder head and valve mechanism D-245
If it is necessary to replace the valve seats, use a set of special mandrels shown in the figures

All seals and gaskets of the pump and its drive must be replaced during assembly.
The pump is assembled in the reverse order of disassembly.
After repair, the pump must be tested for performance on a special stand.

When buying rear hubs for a car, you need to consider that there are old-style and new-style hubs.
Let's look at the main differences between the hubs so as not to confuse them during installation.

ZIL-5301 Rolling Bearings
The figure shows the locations of the bearings and their designations according to the spare parts catalog.

Electrical diagram of the electro-pneumatic door drive ZIL-5301
An electro-pneumatic door closing drive is used on buses and special vehicles. The electrical diagram of the drive is shown below

The oil-moisture separator is designed to clean compressed air from moisture and oil, and to prevent condensate from freezing in air lines and pneumatic drive units.

The ZIL-5301 and its modifications are equipped with a voltage regulator mod. 4202.3702 (installation of mod. 206.3702 or 207.3702 is possible), designed to work with the generator mod. 2022.3771, and having two isolated terminals "Ш" and "+"

On the ZIL-5301, in addition to the voltage regulator relay, which is located to the left of the driver's seat below, there is also an excitation winding relay
