Cylinder Block - check status
1. Upon detection of external defects (cracks and chips), repair or replace the unit. It is recommended to check for internal defects in the engine block, which must pass a block to the studio Car. 2. Check the roundness and taper of the cylinder, measure the diameter in three dimensions, in directions parallel and perpendicular to the axis of the unit (see photo). If the results are different from the standard, the unit should be returned to the workshop repair. After the restoration of the block need pistons and rings of the repair sizes. 3. If the state of the cylinder acceptable wear of the cylinder and the gap between the cylinder and the piston do not exceed the established norms, the cylinders need othon-ningovat (photo). The work is recommended to perform in the service station. 4. Check the deformation of a demountable plane of the cylinder (see photo). If the deviation from a plane exceeds norm, the unit should be abraded in the workshop car service. The thickness of the material taken from the unit should not exceed the thickness of the material removed from the head. If the total size, which decreased after grinding igolovka unit exceeds 0.2 mm, the head and the unit should be replaced.
