Piston: Testing and Inspection
Block and Piston Inspection
1. Remove the crankshaft and pistons.
2. Check the piston for distortion or cracks.
3. Measure the piston diameter at a point 10 mm (0.4 in.) from the bottom of the skirt. There are two standard-size pistons (/(slash) and B). The letter
is stamped on the top of the piston. Letters are also stamped on the block as cylinder bore sizes.
4. Measure the wear and taper in direction X and Y at three levels in each cylinder as shown. If the measurements in any cylinder are beyond the
Oversize Bore Service Limit, replace the block. If the block is being rebored, refer to step 7 after reboring.
