Piston: Testing and Inspection
INSPECTION
1. Check the piston for distortion or cracks.
NOTE: If the cylinder is bored, an oversized piston must be used.
2. Measure the piston diameter at a point 21 mm from the bottom of the skirt.
NOTE: 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): 84.980-84.990 mm (3.3457-3.3461 in.)
B: 84.970-84.980 mm (3.3453-3.3457 in.)
Service Limit:
No Letter or A): 84.970 mm (3.3453 in.)
B: 84.960 mm (3.3449 in.)
3. Calculate the difference between the cylinder bore diameter and piston diameter.
Piston-to-Cylinder Clearance:
Standard (New): 0.020-0.040 mm (0.0008-0.0016 in.)
Service Limit: 0.05 mm (0.002 in.)
If the clearance is near or exceeds the service limit, inspect the piston and cylinder block for excessive wear.
Oversize Piston Diameter:
0.25: 85.230-85.240 mm 13.3555-3.3559 in.)
0.50: 85.480-85.490 mm (3.3653-3.3657 in.)
