Repair ZIL-5301
The ZIL-5301 "Bychok" is a light-duty truck whose specifications vary depending on the model, but generally speaking, it features a 4.75-liter diesel engine (producing between 109 and 130 hp), a payload capacity of approximately 3–3.5 tons, and a top speed of 95 km/h.
Key features include rear-wheel drive, a five-speed manual transmission, and reinforced suspension with leaf springs.
The final drive can be adjusted or repaired without removing the rear axle from the vehicle.
The preload of the final drive bearings, the lateral clearance in the engagement and the contact patch are adjusted at the factory and, as a rule, they do not require adjustment during operation.
