B. Inspect connecting rod bolts
Using vernier calipers, measure the minimum diameter of
the compressed bolt at the measuring point.
Standard diameter: 8.300-8.400 mm
(0.3268-0.3307 in.)
Minimum diameter: 7.95 mm (0.3130 in.)
If the diameter is less than minimum, replace the connect-
ing rod bolt.
C. Inspect piston pin oil clearance
(a) Using a caliper gauge, measure the inside diameter of
the connecting rod bushing.
Bushing inside diameter:
IPZ and 1HZ
29.008-29.020 mm (1.1420-1.1425 in.)
1HD-T
33.008-33.020 mm (1.2995-1.3000 in.)
(b) Using a micrometer, measure the piston pin diameter.
Piston pin diameter:
1PZ and 1HZ
29.000-29.012 mm (1.1417-1.1422 in.)
1HD-T
33.000-33.012 mm (1.2992-1.2997 in.)
(c) Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance: 0.004-0.012 mm
(0.0002-0.0005 in.)
Maximum oil clearance: 0.03 mm (0.0012 in.)
7. IF NECESSARY, REPLACE CONNECTING ROD
BUSHINGS
A. Remove connecting rod bushings
Using SST and a press, press out the bushing.
