3. Remove nut/locknut (38) securing output yoke/
flange (39) on transmission (1). Pull output yoke/flange
(39) from transmission (1).
4. Remove bolts (10) and lockwashers (11) securing
mounting brackets (9) to transmission (1). Remove
mounting brackets (9).
5. If necessary, remove isolation mounts (12) from
mounting brackets (9).
ASSEMBLY
Numbers in parentheses refer to Fig. 1.
Note: Tighten all fasteners without special torques
specified to standard torques listed in Section
300-0080, STANDARD BOLT AND NUT TORQUE
SPECIFICATIONS.
1. Secure mounting brackets (9) to transmission (1)
assembly with bolts (10) and lockwashers (11).
Tighten bolts (10) to a torque of 156 Nm (115 lbf ft). If
removed, install isolation mounts (12) to mounting
brackets (9).
2. If removed, fit new ring (31) to trunnion (2) and mount
trunnion (2) to the front of transmission (1) with small leg
to the top and facing away from transmission (1).
3. Make sure that transmission input shaft is in its
most outward position and the bearing is seated
against the shaft shoulder.
4. Coat input shaft splines and lip of oil seal with a thin
layer of EP, NLGI molybdenum grease. Install input
yoke (37) on input shaft by tapping lightly until the
yoke is seated. If input yoke (37) is a tight fit, heat
input flange (37) to 121° C (250° F) maximum prior to
assembly. Two methods which may be employed are:
a. Heat in controlled temperature furnace for a
minimum period of 45 minutes.
b. Submerge flange in heated oil for 15 minutes.
5. Use proper combination of shims (35 & 36) to obtain
a 0.2 - 0.3 mm (0.008 - 0.012 in) gap between retainer
face of input yoke (37) and end of input shaft. Fit
retainer (34) and secure with bolts (32) and strip (33).
Tighten bolts (32) to a torque of 130 - 156 Nm
(96 - 115 lbf ft).
6. Coat output shaft splines and threads, and lip of oil
seal with a thin layer of EP, NLGI molybdenum
grease. Install output yoke/flange (39) on output shaft
by tapping lightly until the yoke is seated. If output
yoke/flange (39) is a tight fit, heat output yoke/flange
(39) to 121° C (250° F) maximum prior to assembly,
using either of the methods described in step 3.
7. Secure output yoke/flange (39) on output shaft with
nut/locknut (38). Tighten nut (38) to a torque of
950 - 1 355 Nm (700 - 1 000 lbf ft).
8. After assembly has cooled, check torque of bolts
(32) and nut/locknut (38) and retighten to their required
torques.
INSTALLATION
Numbers in parentheses refer to Fig. 1.
Note: Tighten all fasteners without special torques
specified to standard torques listed in Section
300-0080, STANDARD BOLT AND NUT TORQUE
SPECIFICATIONS.
WARNING
To prevent personal injury and property
damage, be sure wheel chocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
1. Position transmission (1) assembly under the
vehicle and attach a suitable lifting device to the eye
bolts on top of transmission (1).
2. Carefully lift transmission (1) assembly into its
mounting position and lightly secure trunnion (2) to the
frame (mounting face to the front of the frame
mounting brackets) with bolts (3), washers (4) and
locknuts (5). Install bolts (3) from the rear of the
assembly.
3. Install bolts (6), hardened washers (7), snubbing
washers (43) and nuts (8) securing mounting brackets
(9) to frame mounting brackets. Securely tighten bolts
(6) to a torque of 278 Nm (205 lbf ft).
4. Securely tighten bolts (3), securing trunnion (2) to
frame mounting brackets, to a torque of 156 Nm
(115 lbf ft).
5. Remove lifting device and lifting eye bolts from top
of transmission (1).
6. Install filler hose (16) to filler tube (17) and adaptor
(25) and secure with clamps (15).
