Cylinder Block Inspection / Repair

Cylinder Block Inspection / Repair





1. Measure the distortion of the cylinder block top surface in the six directions. Repair by grinding or replace as necessary.
Cylinder block distortion 0.15 mm (0.006 inch) maximum
Cylinder block height 221.5 mm (8.720 inch)
Grinding 0.20 mm (0.008 inch) maximum





2. Measure the cylinder bores in X and Y directions at 35 mm (1.38 inch) below the top surface.
3. If the cylinder bore exceeds the wear limit, replace the cylinder block or rebore the cylinder and install the oversize pistons so that the specified piston-to-cylinder clearance is obtained.

Note:
^ Base the boring diameter on the diameter of an oversize piston. All cylinders must be the same diameter.
