The block of cylinders


Remove a head of cylinders, a gear belt, a forward cover, a flywheel, pistons and a cranked shaft.


The block of cylinders


    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 and other defects.
    Measure diameters of cylinders in opposite directions (And and), in three planes on height of cylinders (1, 2 and 3).
    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 is necessary for chiseling and отхонинговать, and also to establish new pistons and piston rings of the repair size.

Nominal diameter of the cylinder: 83 0,03 mm
Конусность the cylinder: no more than 0,01 mm

    If in the top part of the cylinder there is a step, cut off its special tool.
    As spare parts pistons of four increased sizes are delivered: 0,25, 0,5, 0,75 and 1,00 mm. 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. Standard measurement of external diameter of the piston is necessary to spend on distance of 2 mm from a skirt and to perpendicularly persistent surfaces. A backlash between the piston and the cylinder: 0,069–0,091 mm.
    Check up the block of cylinders on absence of damages and cracks. 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:

– On width: 0,042 mm;
– On length: 0,096 mm;
– On a diagonal: 0,012 mm.

Maximum permissible deviation from planeness: 0,1 mm.

The privalochnaja surface for a lining of the block of cylinders after repolishing should reduce height of the block of cylinders no more than–0,2 mm.

Расточка cylinders


    Pistons of the increased size which should be used to be defined on the basis of the greatest diameter of an aperture of the cylinder.
Increase in the size
0,25 mm
0,50 mm
0,75 mm
1,00 mm

Marks are beaten out on the piston bottom.

    Measure external diameter of the piston. On the basis of the measured size define the size расточки. The size расточки = Diameter of the piston 0,02 mm (size хонингования). Chisel each of cylinders till the settlement size.

For an exception of change of the size from temperature in process хонингования, process cylinders in the following sequence: №2, №4, №1 and №3.

    Хонингуйте cylinders before reception of the demanded settlement diameter (external diameter of the piston a backlash). Check up a backlash between the piston and the cylinder.

At расточке, chisel all cylinders till one increased size. Do not chisel only one cylinder till the increased size.
