Cylinder Bore

CYLINDER BORE
Use a cylinder gauge to measure the cylinder bore diameter in both the axial and thrust directions. Each measurement should be made at six points.

CAUTION: Be very careful not to allow any material to accidentally drop into the upper surface of the cylinder block. Be very careful not to scratch the upper surface of the cylinder block.

Cylinder Bore Inside Diameter
Limit 93.530 (3.6823)





If the measurement exceed the specified limit, the cylinder block must be replaced.

Diameter
Grade A 93.400 mm - 93.410 mm (3.6772 inch - 3.6776 inch)
Grade B 93.411 mm - 93.420 mm (3.6776 inch - 3.6779 inch)
Grade C 93.421 mm - 93.430 mm (3.6780 inch - 3.6783 inch)
