MAINTENANCE MANUAL - Meritor

14. Use a press and a sleeve to press the shaft
of the drive pinion out of the outer bearing
cone. Do not press the shaft of the drive
pinion out of the helical driven gear.
15. Remove the outer bearing cone and the two
pieces of lead or solder from the outer bearing
cone.
16. Use a micrometer to measure the thicknesses
of the compressed pieces of lead or
solder. Add the measurements of the two
pieces and divide by two (2) to determine
the average size of the pieces. Add 0.004inch
(0.100 mm) to the average size. Use
this dimension to determine the size of the
spacer to install between the helical driven
gear and the outer bearing. See Table G.
TABLE G
17. Place a wood block under the head of the
drive pinion so that the inner bearing cone
on the pinion touches the inner bearing cap
in the differential case. Remove the supports
from the differential case. Figure 5.15.

CAUTION
Assembly and Installation
DO NOT APPLY PRESSURE AFTER THE
HELICAL DRIVEN GEAR TOUCHES THE
SPACER IN FRONT OF THE INNER BEAR-
ING ON THE DRIVE PINION. IF PRESSURE
IS APPLIED AFTER THE PARTS TOUCH
EACH OTHER, THE GEAR WILL DAMAGE
THE SPACER.
NOTE:
The inner bearing cone on the drive pinion
must touch the inner bearing cap in the differential
case, when the helical driven gear
is being installed.
18. Use a press and a sleeve to completely install
the helical driven gear on the drive pinion.
Use a sleeve on the hub of the gear that
fits inside the pinion bore. Press the gear in
the drive pinion until the gear touches the
spacer. Do not remove the wood block at
this time. Figure 5.14
19. Install the correct size spacer the shaft of
the pinion in front of the helical driven gear.
NOTE:
Verify that the wood block is still under the
head of the drive pinion. The inner bearing
cone on the pinion must touch the cap in
the differential case.
20. Install the outer bearing cone into the shaft
of the drive pinion. Figure 5.15.
A. Place the outer bearing cone on the shaft of
the drive pinion.
B. Place a sleeve in the top, inner race, of the
outer bearing cone.
C. Use a press to apply 2 tons (1814 kg) of
force on the bearing cone to install the cone
into the shaft of the drive pinion. Rotate the
differential case in both directions, while
the cone is being installed to verify that the
bearing cone is correctly installed.
21. Release the pressure and remove the differential
case from the press. Place the differential
case in a repair stand.
