Ring groove clearance:
Before checking, piston grooves must be clean, dry and free of carbon.
Fit new piston ring (1) into piston groove, and measure clearance between ring and ring land by using thickness gauge (2).
If clearance is out of specification, replace piston.
Ring groove clearance
Top: 0.03 - 0.07 mm (0.0012 - 0.0027 inch)
2nd: 0.02 - 0.06 mm (0.0008 - 0.0023 inch)
Piston Pin
^
Check piston pin, connecting rod small end bore and piston bore for wear or damage, paying particular attention to condition of small end bore
bush. If pin, connecting rod small end bore or piston bore is badly worn or damaged, replace pin, connecting rod or piston.
^
Piston pin clearance: Check piston pin clearance in small end.
Replace connecting rod if its small end is badly worn or damaged or if measured clearance exceeds limit.
Piston pin clearance in small end (standard): 0.003 - 0.014 mm (0.0001 - 0.0005 inch)
Small-end bore: 21.003 - 21.011 mm (0.8269 - 0.8272 inch)
Piston pin diameter: 20.997 - 21.000 mm (0.8267 - 0.8268 inch)
