22. Measure clearance between retaining plate and snap ring. If not
within specified clearance, select proper retaining plate.
23. Install needle bearing to transmission case.
CAUTION:

Take care with the direction of needle bearing. Refer to
AT-260, "
Locations of Adjusting Shims, Needle Bearings,
Thrust Washers and Snap Rings" .

Apply petroleum jelly to needle bearing.
24. Install revolution sensor to transmission case. Tighten revolution
sensor bolt to the specified torque. Refer to AT-250, "
Compo-
nents" .
CAUTION:

Do not subject it to impact by dropping or hitting it.

Be careful not to damage harness with the edge of case.

Do not allow metal filings, etc., to get on the sensor's
front edge magnetic area.

Do not place in an area affected by magnetism.
25. Install new rear oil seal into the rear extension (2WD models) or
adapter case (4WD models) until it is flush with component face,
using Tool or suitable drift.
CAUTION:

Apply ATF to rear oil seal.

Do not reuse rear oil seal.Specified clearance “A”:
Standard: 0.7 - 1.1mm (0.028 - 0.043 in)
Retaining plate:
Refer to AT-323, "
