Checking the tightening of the cylinder head mounting bolts

Check the tightening of the cylinder head mounting bolts after the break-in period and every 40 thousand km of run on a warmed-up diesel engine in the following order:

Carburetor K-151V (Fig. 1) - vertical, emulsion, two-chamber, with a falling mixture flow and sequential opening of the throttle valves

The GA3-66 vehicle is a two-axle truck, with a payload capacity of 2 tons, all-terrain, with drive on both axles. It is designed to replace the same type of GAZ-63 car produced by the plant
