1. Measure the diameter of the piston pin.

Piston Pin Diameter:

B16A2 engine:

Standard (New): 20.994 - 21.000 mm (0.8265 - 0.8268 inch)
Oversize: 20.997 - 21.003 (0.8267 - 0.8269 inch)

D16Y5, D16Y7, D16Y8 engines:

Standard (New): 18.994 - 19.000 mm (0.7478 - 0.7480 inch)
Oversize: 18.997 - 19.003 (0.7479 - 0.7481 inch)

NOTE: All replacement piston pins are oversize.

2. Zero the dial indicator to the piston pin diameter.

3. Measure the piston pin-to-piston clearance.

NOTE: Check the piston for distortion or cracks.

If the piston pin clearance is greater than 0.024 mm (0.0009 inch), remeasure using an oversized piston pin.

Piston Pin-to-Piston Clearance:
