Cylinder Block

CYLINDER BLOCK





1. Measure the distortion of the cylinder block top surface in the six directions shown in the figure.

Distortion: 0.15 mm (0.006 in) max.

2. If the distortion exceeds the maximum, repair by grinding or replace the cylinder block. If the cylinder block height is not within specification, replace it.

Grinding: 0.20 mm (0.008 in) max.
Height: 221.5 mm (8.72 in)





3. Measure the cylinder bores in X and Y directions at the three points (A, B, and C) in each cylinder as shown. If the difference between measurements A and C or measurements X and Y exceeds the wear limit, replace the cylinder block or rebore the cylinder to oversize.

Note
^ The boring size should be based on the same size as an oversize piston and the same for all cylinders.
