(10) Install the UD clutch pack. Leave out upper
disc, until snap ring is installed (Fig. 250).
(11) Install the UD clutch flat snap ring (Fig. 251).
(12) Install the last UD clutch disc (Fig. 252).
(13) Install the OD/UD clutch reaction plate and
snap ring (Fig. 253) (Fig. 254). The OD/UD clutches
reaction plate has a step on both sides. Install the
OD/UD clutches reaction plate tapered step side up.
NOTE: Snap ring ends must be located within one
finger of the input clutch hub. Be sure that snap
ring is fully seated, by pushing with screwdriver,
into snap ring groove all the way around.

(15) Install input clutch assembly to the Input
Clutch Pressure Fixture±Tool 8391 (Fig. 257).
(16) Set up dial indicator on the UD clutch pack as
shown in (Fig. 258).
(17) Using moderate pressure, press down and
hold (near indicator) the UD clutch pack with screw-
driver or suitable tool and zero dial indicator (Fig.
259). When releasing pressure on clutch pack, indica-
tor reading should advance 0.005±0.010.
CAUTION: Do not apply more than 30 psi (206 kPa)
to the underdrive clutch pack.
(18) Apply 30 psi (206 kPa) to the underdrive hose
on Tool 8391 and measure UD clutch clearance. Mea-
sure and record UD clutch pack measurement in four
(4) places, 90É apart.
(19) Take average of four measurements and com-
pare with UD clutch pack clearance specification.
Underdrive clutch pack clearance must be 0.94-
1.50 mm (0.037-0.059 in.).
(20) If necessary, select the proper reaction plate
to achieve specifications:
UNDERDRIVE REACTION PLATE THICKNESS

(22) Install OD pressure plate waved snap ring
(Fig. 261).(23) Install the OD/Reverse pressure plate with
large step down (towards OD clutch pack) (Fig. 262).

(25) Measure OD clutch pack clearance. Set up
dial indicator on top of the OD/Reverse pressure
plate as shown in (Fig. 265).
(26) Zero dial indicator and apply 30 psi (206 kPa)
air pressure to the overdrive clutch hose on Tool
8391. Measure and record OD clutch pack measure-
ment in four (4) places, 90É apart.
(27) Take average of four measurements and com-
pare with OD clutch pack clearance specification.
The overdrive (OD) clutch pack clearance is
1.07-3.25 mm (0.042-0.128 in.).
If not within specifications, the clutch is not
assembled properly. There is no adjustment for the
OD clutch clearance.
(28) Install reverse clutch pack (two frictions/one
steel) (Fig. 266).
(29) Install reverse clutch reaction plate with the
flat side down towards reverse clutch (Fig. 267).
