Engine Block: Inspection

The cylinder walls should be checked for out-of-round and taper with Special Tool C-119. See Fig 1. If the cylinder walls are badly scuffed or scored, the cylinder bore can be machined oversize. Oversize piston and rings are available.

Measure the cylinder bore at three levels in directions A and B. See Fig 1. Top measurement should be 12 mm (0.50 in.) down and bottom measurement should be 12 mm (0.50 in.) up from bottom of bore. (Refer to ENGINE - SPECIFICATIONS)  for cylinder bore and piston specifications.
