CYLINDER INSPECTION

CYLINDER DISTORTION

• Check the gasketed surface of the cylinder for distortion with

a straightedge and thickness gauge, taking a clearance read-
ing at several places 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: 77.000 – 77.015 mm (3.0301 – 3.0307 in)
