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

The clutch of the YaMZ-238 model is double-disc, dry, friction type, with a peripheral arrangement of cylindrical springs

Installing cylinder heads, valve rocker arms and adjusting valve clearances

The cylinder head mounting studs are screwed into the right and left rows of the cylinder block, having previously lubricated the threaded holes for the studs in the block with diesel oil

The engine consists of a crank and gas distribution mechanisms, as well as cooling, lubrication, power and control systems, and starting

Let's consider the malfunctions that may occur during engine operation:

  • - The crankshaft is not turned by the starter;
