Inspection of Piston Pin Hole
Measure piston pin hole inner diameter, and replace
piston if the inner diameter is over the limit.
Piston Pin Hole : Standard Value
23.00 mm (0.9056 in)
Functional Limit :
23.03 mm (0.9067 in)
6.
Inspection of Piston Pins
Measure piston pin outer diameter, and replace piston pin
if the outer diameter is over the limit.
Piston Pin Outer Diameter : Standard Value
23.00 mm (0.9056 in)
Functional Limit :
22.97 mm (0.9045 in)

Inspection of Piston Pin Clearance
Calculate piston pin clearance, and replace piston and
piston pin together if the clearance is over the limit.
Calculation of Piston Pin Clearance :
Piston Pin Hole Inner Diameter - Piston Pin
Outer Diameter
Standard Value :
0.015 - 0.025 mm (0.00059 - 0.00098 in)
Functional Limit :
0.040mm (0.0016 in)
Use the maximum values of piston pin hole inner
diameters and piston pin outer diameters
measured respectively.
