Cylinder Bore
The cylinder walls should be checked for out-of-round and taper with Tool C119 or equivalent (Fig 1) (Refer to SPECIFICATIONS ). 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 1). Top measurement should be 10 mm (3/8 in.) down and bottom measurement should be 10 mm (3/8 in.) up from bottom of bore. (Refer to SPECIFICATIONS ).
