THE NOTE
It is authorised to replace a head of the block of cylinders and a frame of cam-shafts only together.

After installation of cam-shafts the engine it should is impossible to get Hydrojacks within approximately 30 minutes to be besieged (differently valves will adjoin to pistons).
After works over клапанным the mechanism scroll the engine by hand not less than two turns to be convinced that any valve does not adjoin to the piston.
And манжетные consolidations it is necessary to replace consolidations.
