INSPECTION AND REPAIR 1
A
5. Measure each piston ring end gap using a feeler
gauge, replace if necessary.
End gap
TOP
: 0.20-0.40 mm (0.008-0.016 in)
Second: 0.15-0.30 mm (0.006-0.012 inj
Oil rail : 0.20-0.70 mm (0.006-0.028 in)
Maximum: 1.0 mm (0.039 in)
Piston and Piston Pin
1. Measure the piston pin hole diameter in X and Y
directions at four places.
Diameter:
19.988-20.000 mm (0.7869-0.7874 in)
2. Measure the piston pin diameter in the same
manner.
Diameter:
19.974-19.980 mm (0.7884-0.7866 in)
3. Check the piston pin to piston clearance.
Clearance:
0.008-0.026 mm (0.0003-0.0010 in)
4. If the clearance exceeds the maximum, replace the
piston and/or piston pin.
Connecting Rod
I. Measure the connecting rod small end bore
Diameter:
19.948-19.961 mm (0.7854-0.7859 in)
2. Check the interference between the small end
bore and piston pin.
Interference:
0.013-0.032 mm (0.0005-0.0013 in)
