Cleaning and Inspection
CLEANINGClean cylinder block thoroughly.
INSPECTION
Inspect all core hole plugs for evidence of leaking and replace as necessary. Examine block and cylinder bores for cracks or fractures.
The cylinder walls should be checked for out-of-round and taper with Tool C119 (Fig. 169). The cylinder bore out-of-round is 0.050 mm (0.002 inch) maximum and cylinder bore taper is 0.051 mm (0.002 inch) maximum. If the cylinder walls are badly scuffed or scored, the cylinder block should be replaced, and new pistons and rings fitted.
Measure the cylinder bore at three levels in directions A and B (Fig. 169). Top measurement should be 10 mm (3/8 inch) down and bottom measurement should be 10 mm (3/8 inch) up from bottom of bore.
