DIFFERENTIAL (Continued)
(14) Measure and verify differential side gear end
play. (Refer to 21 - TRANSMISSION/TRANSAXLE/
MANUAL/DIFFERENTIAL - ADJUSTMENTS).
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 bear-
ing plate-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. 91). 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.
