OUTPUT FLANGE SHIM SELECTION
This procedure is used when the output flange is
replaced. Replacement of the output flange requires
installation of the correct size shim to maintain bear-
ing preload.The shim must protrude from the
new output flange the same distance that the
original shim protruded from the original
flange.
(1) Stand the original output flange on end with
shim side pointing up.
(2) Place original shim into groove in top of flange.
(3) Place a straight edge across the shim.
(4) Using feeler gauge, measure the distance
between the straight edge and the top of the flange
(Fig. 15). Record this measurement.
(5) Repeat steps Step 1 through Step 4using the
new flange and the original shim.Record this
measurement.
(6) If measurements are not equal, use a new shim
that protrudes from new output flange. Make sure it
protrudes the same amount.
(7) For Example: The original shim protrudes
0.075 inch from the original output flange. Place the
original shiminto the new output flange. The pro-
trusion of the shim in the new flange is 0.085 inch.
This indicates that a 0.010 inch thinner shim is
required to maintain the original protrusion.(8) Install output flange and torque flange nut to
244 N´m (180 ft. lbs.).
(9) Check the turning torque of the pinion before
installing the rear cover into the P.T.U. The turning
torque should be between 2.0 N´m and 2.5 N´m (17
in. lbs. and 22 in. lbs.).

T850 MANUAL TRANSAXLE
DESCRIPTION
The NV T850 5-speed transaxle (Fig. 1) is a con-
stant-mesh manual transaxle that is synchronized in
all gear ranges, including reverse.The transaxle consists of three major sub-assem-
blies: the input shaft, intermediate shaft, and differ-
ential assembly. The transaxle shift system consists
of a mechanical shift cover, rails, forks, and cables.
The unique design of this shift system provides a
higher mechanical advantage, resulting in less fric-
tion and lower shift cable loads for smoother, more
positive operation.

(17) Remove 1-2/5-R shift rail (Fig. 40). (18) Install lifting bar 8489.
(19) Lift geartrain (w/reverse idler gear assy.) out
of transaxle and install on fixture 8487 (Fig. 41).
(20) Remove remaining shift rail and forks from
geartrain (Fig. 41).
(21) Remove lifting bar from geartrain.
NOTE: At this point, differential bearing turning
torque should be measured to ensure proper shim
selection upon reassembly.
(22) Reinstall and torque extension housing and
measure differential turning torque. (Refer to 21 -
TRANSMISSION/TRANSAXLE/MANUAL/DIFFER-
ENTIAL - ADJUSTMENTS)
(23) Remove differential cover bolts.
(24) Remove differential cover. If necessary, use a
soft tipped hammer to aid in removal.
(25) Remove extension housing.
(26) Remove differential assembly. Note orienta-
tion of shim, oil slinger, and differential side bearing
races (Fig. 42).

NOTE: When assembling this transaxle, always use
NEW snap rings.
NOTE: Before assembling transaxle, differential
turning torque must be measured and adjusted.
(Refer to 21 - TRANSMISSION/TRANSAXLE/MANU-
AL/DIFFERENTIAL - ADJUSTMENTS). Differential
turning torque must be measured with geartrain out
of case.
