DIFFERENTIAL
DESCRIPTION
The T850 differential is a conventional open
design. It consists of a ring gear and a two-piece dif-
ferential case. The differential case contains the pin-
ion and side gears, three floating pinion shafts, and a
pinion shaft retaining ring (Fig. 104). The differential
case is supported in the transaxle by tapered roller
bearings.
OPERATION
The differential assembly is driven by the interme-
diate shaft via the ring gear. The ring gear drives the
differential case, and the case drives the halfshafts
through the differential gears. The differential pinion
and side gears are supported in the case by pinion
shafts and thrust washers. Differential pinion and
side gears make it possible for front wheels to rotate
at different speeds while cornering.

(10) Install thrust buttons 8491 to both bearing
journals and press halves together using an arbor
press (Fig. 127).
(11) Install ring gear into position, start three ring
gear-to-differential case bolts by hand (120É apart),
and install alignment pins 8470 (Fig. 128).
(12) Torque three ring gear bolts to draw ring gear
into position. Remove alignment pins, install remain-ing ring gear-to-differential case bolts and torque to
95 N´m (70 ft. lbs.) (Fig. 129).
(13) Install tapered roller bearings using installer
8473 and an arbor press (Fig. 130). Insert button
8491 on opposite journal to protect journal and/or
bearing during press operation. Repeat the same
operation on opposite side.

(14) Measure and verify differential side gear end
play. (Refer to 21 - TRANSMISSION/TRANSAXLE/
MANUAL/DIFFERENTIAL - ADJUSTMENTS).
ADJUSTMENT - DIFFERENTIAL TURNING
TORQUE
NOTE: Differential turning torque should only be
measured with the geartrain out of the transaxle. If
measurement is taken with transaxle assembled, an
inaccurate measurement will result.
NOTE: All differential cover-to-case bolts and exten-
sion housing-to-case bolts must be installed and
torqued to obtain accurate measurement.
(1) If transaxle is assembled, remove geartrain
and leave differential in place. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/MANUAL - DISASSEMBLY)
(2) Install differential cover and torque differential
cover-to-case bolts to 54 N´m (40 ft. lbs.).
(3) Install extension housing and torque extension
housing-to-case bolts to 28 N´m (250 in. lbs.).
(4) Place transaxle on work bench so axle center-
line is parallel to the ground.
(5) Install turning torque tool C-4995 to differen-
tial at side opposite extension housing.
(6) Using in. lb./N´m dial indicator, rotate differen-
tial case multiple times and record measurement
(Fig. 131). Differential turning torque should be
within 2.3-3.4 N´m (20-30 in. lbs.). Refer to shim
chart for proper shim selection. If turning torque
measured is less than 2.3 N´m (20 in. lbs.), install a
thicker shim. If turning torque measured is greater
than 3.4 N´m (30 in. lbs.), install a thinner shim.
