The block of cylinders


At full dismantling of the block of cylinders carefully clear and remove extraneous particles from cavities and oil channels. Completely remove the rests of cleaning liquids. Will pay on this special attention. If there is a possibility, blow the block of cylinders dry air.
For backlash definition in interface of the piston to the cylinder measure diameter of pistons. At engines of all types it becomes in the bottom part of a skirt of the piston. The received values write down. Further diameters of cylinders as it is described more low are measured. For this purpose use нутромер:

1. Measure diameter of the cylinder at height of 10 mm from the top edge and 10 mm from the bottom edge.
2. In addition measure diameter on half of height of the cylinder.
3. Specified above measurement are carried out in a direction of longitudinal and cross-section axes of the block of cylinders. Thus, for each cylinder it is carried out six measurements. A difference between top and bottom measurements - it конусность, a difference between diameters in longitudinal and cross-section directions - ovality of the piston. Any of received diameters should not be less, resulted in Specifications. There are some repair sizes of pistons. The block of cylinders can be chiseled in appropriate way. The interfaced surface of the block of cylinders should be checked up on неплоскостность also as it becomes concerning a head of cylinders. The surface is checked in longitudinal, cross-section and diagonal directions. Maximum неплоскостность - no more than 0.10 mm.
