Cylinder distortion
Check the gasketed surface of the cylinder for distortion with a straightedge and thickness gauge, taking a clearance reading at several places as indicated.
If the largest reading at any position of the straightedge exceeds the limit, replace the cylinder.
Cylinder distortion:
- Service Limit: 0.05 mm (0.002 in)
- 09900-20803: Thickness gauge
Cylinder bore
Inspect the cylinder wall for any scratches, nicks or other damage. Measure the cylinder bore diameter at six places.
Cylinder bore:
- Standard: 81.000-81.015 mm (3.1890-3.1896 in)
- 09900-20508: Cylinder gauge set
