If the head of the block of cylinders did not act in film, it is necessary to put a hermetic layer on the top surface of a cover of a drive of the mechanism of a gazoraspredeleniye. Combine a leading gear wheel of the oil pump and the plug of a drive and establish into place a cover of a drive of the mechanism of a gazoraspredeleniye. Putting on a cover a sock of a cranked shaft, watch to damaging a cuff edge.
Establish into place bolts of fastening of a cover of a drive and tighten them the set moment.
