Checking Transfer Gear/Output Shaft
Assembly End Float
The transfer gear/output shaft and its associated
components are manufactured using a ‘Setright’ system.
Measure the rolling torque at the yoke
1h
. Provided
components have been assembled correctly the torque will
be between 0.6 and 2.2 Nm (0.5 and 1.6 lbf ft).

Powershift Gearbox
Assembly
Using suitable lifting equipment locate the gearbox rear
casing in a work cradle. Clamp the casing in position at the 3
clamping points as shown at
A
.
DO NOT ATTEMPT TO ASSEMBLE THE GEARBOX UNLESS
IT IS SAFELY LOCATED IN A SUITABLE WORK CRADLE.
Where ‘oil’ is referred to, use new, clean transmission oil of
the correct specification for the gearbox. See
Section 3,
Lubricants and Capacities
.

Assemble the Transfer Gear/Output Shaft
Note 1:
Before fitting the transfer gear/output shaft assembly
1d
, fit the layshaft outer bearing cup to the casing (shown at
E
).
Position the casing as shown at
D
.
Note 2:
The inner and outer taper roller bearing assembly
(comprising double outer cup
1a,
inner bearing
1c
, spacer
1e
and outer bearing
1f
) is a matched set. Keep all the
components together in their original relationships.
Components from another set are not interchangeable. If any
components are worn or damaged the whole assembly must
be renewed as a complete matched set.
a
Make sure that you have fitted the layshaft outer bearing
cup, see
Note 1
above. Fit the bearing double outer cup
1a
into the casing. Note the correct way up of circlip
1b
,
with the chamfer uppermost. Make sure that the circlip
locates fully in its groove as shown at
B
. The tangs of
the circlip must not overhang the inner diameter of the
bearing cup 1
a
. An incorrectly located circlip can foul
and damage the outer bearing.
b
Push the inner bearing
1c
onto the transfer gear/shaft
1d
followed by spacer
1e
.
d
Locate the transfer gear assembly in the casing from
inside. Using service tool 892/01083 retain the gear in
position (shown at
C
). If the gear is not held in position
the bearings may be damaged during assembly.
c
Using service tool 892/01084 push on the outer bearing
1f
. Using service tool 892/01085 fit a new oil seal
1g
.
Make sure the seal is pushed square to the housing.
e
Fit yoke
1h
followed by thick washer
1j
and bolt
1k
. Hold
the yoke using service tool 892/00812 and torque
tighten the bolt to 400 Nm (295 lbf ft).
f
If applicable fit the speed sensor
11f
. Make sure that the
sealing ‘O’ ring is correctly located and then torque
tighten the bolt to 28Nm (20 lbf ft).
