INSPECTION

Combustion Deck Face Measurement:

Measure the combustion deck face using a straight edge and a feeler gauge. The distortion of the combustion deck face is not to exceed 0.010 mm (0.0004 inch) in any 50.00 mm (2.0 inch) diameter. Overall variation end to end or side to side is 0.075 mm (0.003 inch).

If the surface exceeds the limit, refer to Cylinder Block Refacing.

Inspect the cylinder bores for damage or excessive wear.

Cylinder Bore Diameter:

Measure the cylinder bores. If the cylinder bores exceeds the limit, refer to Cylinder Bore Repair.

Inspect the camshaft bores for scoring or excessive wear.

Measure the camshaft bores. Refer to engine specifications at the rear of this section. Limit for the No.1 bore applies to the ID of the bushing.

If a bore exceeds the limit, refer to Camshaft Bore Repair.

Tappet Bore Diameter:

Inspect the tappet bores for scoring or excessive wear. If out of limits, replace the cylinder block.
