ZIL-5301 rear axle gearbox
The car and bus are equipped with a leading rear axle with a single-stage hypoid final drive (Fig. 1).
The final drive ratio is 3.273 or 3.45.
The differential is a bevel gear with four satellites.

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

Adjusting the tension of the differential bearings and monitoring the lateral clearance in the engagement of the main gear
The lateral clearance in the engagement of the main gear, which has increased due to wear of the teeth, is not reduced by adjustment, because this leads to a disruption of engagement and, as a consequence, to increased wear of the teeth, increased noise or breakage of the teeth

The vehicle is manufactured and designed for operation at ambient temperatures from plus 40 to minus 40°C, relative air humidity up to 80% at 20°C, air dustiness up to 0.1 g/m 3

Requirements for the ZIL-5301 timing mechanism parts
The timing mechanism consists of a camshaft, intake and exhaust valves, as well as parts for their installation and drive: tappets, rods, rocker arms, adjusting screws with nuts, plates with crackers, springs, struts and rocker arm shafts
