5) Tighten the new lock nuts using ST1, ST2 and
ST3.
Calculate the lock washer and lock nut specifica-
tions using following formula.
T2 = L2/(L1 + L2) × T1
T1: 116 N·m (11.8 kgf-m, 85.3 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST2 length 0.072 m (2.83 in)
L2: Torque wrench length

NOTE:
Attach ST2 to torque wrench as straight as possi-
ble.

6) Measure the starting torque of the bearing. Make
sure the starting torque is within the specified
range. If the torque is not within specified range, re-
place the roller bearing.
Starting torque:
7.6 — 38.1 N (0.776 — 3.88 kgf, 1.7 — 8.6 lb)
7) Crimp the locknut in 2 locations.
Drive Pinion Shaft Assembly
8) Measure dimension "B" of drive pinion shaft.

ion shim.
100 (10.2, 73.8) t = 6.5 ± 0.0625 – (B – A)

E: INSPECTION
• Make sure that all component parts are free of

scratches, holes and other faults.
• Adjust the tooth alignment. <Ref. to 4AT-91, AD-

face completely.
2) Install the oil pump housing assembly to the con-
verter case, and secure them by tightening the four
bolts evenly.
NOTE:
Use an old gasket or aluminum washer to prevent
damaging the mating surface of the housing.
