(b) Using a groove cleaning tool or broken ring, clean the pis-
ton ring grooves.
(c) Using solvent and a brush, thoroughly clean the piston.
NOTICE:
Do not use a wire brush.
9. INSPECT PISTON OIL CLEARANCE
(a) 1ZZ − FE:
Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 25.6 mm (1.008 in.)
from the piston head.
(b) 2ZZ − GE:
Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 12.0 mm (0.048 in.)
from the piston bottom.
Piston diameter:
1ZZ
− FE:
78.925 − 78.935 mm (3.1073 − 3.1077 in.)
2ZZ − GE:
81.975 − 81.993 mm (3.2274 − 3.2281 in.)
(c) Measure the cylinder bore diameter in the thrust direc-
tions (See procedure in step 5).
(d) Subtract the piston diameter measurement from the cylin-
der bore diameter measurement.
Standard oil clearance:
1ZZ
− FE:
0.065 − 0.088 mm (0.0026 − 0.0035 in.)
2ZZ − GE:
0.007 − 0.038 mm (0.0003 − 0.0015 in.)
Maximum oil clearance:
0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace all the 4
pistons. If necessary, replace the cylinder block.
