Cylinder Block Inspection/Repair

CYLINDER BLOCK INSPECTION/REPAIR





1. Measure the distortion of the cylinder block top surface in the six directions as shown.
^ If the distortion is not as specified, repair by grinding or replace the cylinder block.
Cylinder block distortion 0.15 mm (0.0059 inch) max.
Cylinder block height 221.5 mm (8.720 inch)
Grinding 0.20 mm (0.0078 inch) max.





2. Measure the cylinder bores in X and Y directions at 35 mm (1.38 inch) below the top surface.
^ 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.
