Check for twist
Maximum twist:
0.05 mm (0.0020 ln.) per 100 mm (3.94 ln.)
If twist is greater than maximum, replace the connecting rod as·
sembly.
14. iNSPECT PiSTON PIN Oil CLEARANCE
(a}
Using a caliper gauge, measure the inside diameter of the
connecting rod bushing.
Bushing inside diameter:
1ZZ--FE 20.012 - 20.021 mm (0.7879 - 0.7882 ln.)
2ZZ-GE 20.011 - 20.023 mm (0.7878 - 0.7883 ln.)
(b) 2ZZ-GE:
Using caliper gauge, measure the inside diameter of the
piston bushing.
Bushing inside diameter:
20.013 - 20.025 mm (0.7879 - 0.7884 in.)
(c)
Using a micrometer. measure the piston pin diameter.
Piston pin diameter:
1ZZ--FE 20.004 - 20.013 mm (0.7876 - 0.7879 1n.)
2ZZ-GE 20.004 - 20.016 mm (0.7876 - 0.7880 in.)
(d)
Subtract the piston pin diameter measurement from the
bushing inside diameter measurement.
Standard oil clearance:
1 ZZ--FE 0.005 - 0.011 mm (0.0002 - 0.0004 in.)
2ZZ-GE
Piston x Piston pin
0.005 - 0.013 mm (0.0002 - 0.0005 ln.)
Piston pin x Connecting rod
0.005 - 0.009 mm (0.0002 - 0.0004 in.)
Maximum oil clearance:
0.05 mm (0.0020 ln.)
If the oil clearance is greater than maximum, replace the bush­
ing.
