NOTE: Inspect the piston, piston pin and connecting rod
when they are at room temperature.

(0.8646 - 0.8648 in)
Service Limit: 21.953 mm (0.8643 in)
2. Zero the dial indicator to the piston pin diameter.
3. Check the difference between the piston pin diame-
ter and piston pin hole diameter on the piston.
NOTE: Check the piston for distortion or cracks.
Piston Pin-to-Piston Clearance:
Standard (New): -0.005 to +0.002 mm
(-0.0002 to +0.0001 in)
Service Limit: 0.005 mm (0.0002 in)
4. Measure the piston pin-to-connecting rod clearance.
Piston Pin-to-Connecting Rod Clearance:
