7. INSPECT MAIN BEARING CAP BOLTS
Using vernier calipers, measure the minimum diameter of the
elongated thread at the measuring point.
Standard outside diameter:
10.76 -- 10.97 mm (0.4236 -- 0.4319 in.)
Minimum outside diameter:
10.40 mm (0.4094 in.)
If the diameter is less than minimum, replace the bolt.
8. CLEAN PISTON
(a)
Using a gasket scraper, remove the carbon from the pis-
ton top.
(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)
Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 35.5 mm (1.40 in.)
from the piston head.
Piston diameter:
STD
2RZ--FE: 94.923 -- 94.933 mm (3.7371 -- 3.7375 in.)
3RZ--F: 94.933 -- 94.943 mm (3.7375 -- 3.7379 in.)
O/S 0.50
2RZ--FE: 95.423 -- 95.433 mm (3.7568 -- 3.7572 in.)
3RZ--F: 95.433 -- 95.443 mm (3.7572 -- 3.7576 in)
(b)
Measure the cylinder bore diameter in the thrust direc-
tions.
(c)
Subtract the piston diameter measurement from the cylin-
der bore diameter measurement.
Standard oil clearance:
2RZ--FE: 0.057 -- 0.080 mm (0.0022 -- 0.0031 in.)
3RZ--F: 0.047 -- 0.070 mm (0.0019 -- 0.0028 in.)
If the oil clearance is greater than maximum, replace all the 4
pistons and rebore all the 4 cylinders. If necessary, replace the
cylinder block.
HINT:(Use new cylinder block): Use a piston with the same
number mark as the cylinder bore diameter marked on the cylin-
der block.
