Block and Piston Inspection
1. Remove the piston from the engine block (see page
7-18).
2. Check the piston for distortion or cracks.
3. Measure the piston diameter at a point 16 m m (0.6
in) from the bottom of the skirt. There are two
standard-size pistons (No Letter or A, and B). The
letter is stamped on the top of the piston. Letters
are also stamped on the block as cylinder bore
sizes.
Piston Diameter:
Standard (New):
No Letter (or A):
B:
85.980—85.990 mm
(3.3850 3.3854 in.)

Measure wear and taper in direction X and Y at 3
levels in each cylinder as shown. If measurements
in any cylinder are beyond the Oversize Bore
Service Limit, replace the block. If the block is to be
rebored, refer to step 6 after reboring.
