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:
MP-T model
7.6 — 38.1 N
(0.776 — 3.88 kgf, 1.7 — 8.6 lbf)
VTD model
6.8 — 47.5 N
(0.69 — 4.84 kgf, 1.52 — 10.67 lbf)
7) Crimp the locknut in two locations.
8) Measure dimension "B" of the drive pinion shaft.

9) Calculate the thickness "t" (mm) of the drive pin-
ion shim.
t = 6.5±0.0625 – (B – A)
10) Select three or less shims from following table.

Drive Pinion Shaft Assembly
E: INSPECTION
• Make sure that all component parts are free of
scratches, holes and other faults.
• Adjust the tooth alignment. <Ref. to 4AT-99, AD-
JUSTMENT, Drive Pinion Shaft Assembly.>
F: ADJUSTMENT
1) Remove the liquid gasket from the mating sur-
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.
Tightening torque:

3) Rotate the drive pinion a few times using ST1
and ST2.

5) Apply red lead evenly to the surfaces of three or
0.250 (0.0098)
four teeth on hypoid driven gear. Rotate the drive
0.275 (0.0108)
pinion back and forward several times. Remove the
oil pump housing, and check the teeth contact pat-
tern.
If the teeth contact is inappropriate, adjust the
backlash or thickness of the shim. <Ref. to 4AT-
106, ADJUSTMENT, Front Differential Assembly.>
