Car device

ZIL for emergency service

The “bull” design is considered traditional for medium-capacity rear-wheel drive trucks. The main part of the machine is a rigid frame on which the power units (diesel engine, manual gearbox and clutch) are installed. The cabin and spring units with shock absorbers are also attached to it. Through the chassis of the ZIL 5301 car, the rear and front axles are attached to the frame.

Several types of diesel engines are used on domestic trucks of this brand. All of them are manufactured at the Minsk Automobile Plant. The gearbox is only mechanical.

Truck accessories include:

  • Power steering.
  • Pneumatically assisted hydraulic brakes.

The oil in the power unit must be changed every 10 thousand kilometers. On a serviceable engine, it is not necessary to add lubricant during operation.


But the described car has many disadvantages. Of these, we highlight the most basic:

  1. Sloppy build quality.
  2. The components of the car are not very reliable.
  3. Levers to adjust the driver's seat break quickly.
  4. In winter, the cabin does not heat up to a comfortable level. This is due to the fact that the diesel engine takes a long time to heat up and cannot provide efficient interior heating.
  5. The cab of the truck is poorly made. Gaps can be detected at the joints with the naked eye. While driving, people often complain about drafts, especially during the cold season.
  6. Starting a diesel engine at ZIL in winter is a rather difficult task. It is necessary to preheat the power unit using an electric torch device or an engine preheater.
  7. The starter of the car is powered by 24 volts, and the rest of the electrics are powered by 12 volts. To start the engine successfully, the driver has to switch the starter contacts from one battery to another weekly, since only one of the two power sources is regularly charged.
  8. The rear axle often breaks, resulting in costly repairs.
  9. The manual transmission does not allow efficient acceleration when the vehicle is fully loaded.
