Check

PERFORMANCE ORDER

1. Remove from the block of cylinders of the engine the rests of linings, hermetic, a dirt, oil, lubricant and other alien materials. Visually check up the block of cylinders on absence of a rust, corrosion, cracks or any other defects. 2.

Measure diameters of cylinders in opposite directions, in three planes on height of cylinders. If diameters of cylinders exceed admissible values, have ovality or конусность or the surface of cylinders is damaged or has development, the block of cylinders it is necessary to chisel and establish new pistons and piston rings of the repair size.
