2.1.22. The block of cylinders

Forward arm of the block of cylinders of engine SOHC


Dismantling

PERFORMANCE ORDER
1. Remove a head of cylinders, a gear belt, a forward cover, a flywheel, pistons and a cranked shaft.
2. The special adaptation (09260-32000) turn out the gauge of pressure of oil.

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. Clear interfaced surfaces of a head of the block of cylinders and the block of cylinders of the lining rests. A metal ruler and щупом in six directions check up planeness of an interfaced surface of the block of cylinders.

Deviation from planeness: 0,05 mm
The maximum deviation from planeness: 0,1 mm

3. 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.

Nominal diameter of the cylinder: 75,5 mm
Конусность the cylinder: no more than 0,02 mm

4. If in the top part of the cylinder there is a step, cut off its special tool.
5. As spare parts pistons of four increased sizes are delivered: 0,25, 0,5, 0,75 and 1,00 mm.
6. At расточке cylinders till next increased size, sustain a backlash between the piston and the cylinder and be convinced, that pistons have the same increased size.

Measure external diameter of each piston a sort by a corner 90 to a piston finger, on distance of 12 mm from a piston skirt.

Backlash between the piston and the cylinder: 0,025-0,045 mm
