46 MAINTENANCE MANUAL
6. Place a protector in the head of the drive
pinion. Use a press to install the pinion into
the differential case so that the inner bearing
cone touches the bearing cap. At this time,
the helical driven gear will not be completely
installed on the drive pinion. Figure 5.12.
7. Place the differential case in the press so
that the threaded end of the pinion is toward
theTOP.Placesupportsundertheangeof
the differential case so that the case is level.
Place a wood block under the head of the
drive pinion so the inner pinion bearing cone
touches the inner bearing cap. Figure 5.13.
CAUTION
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.
8. Use a press and a sleeve to completely install
the helical driven gear onto the drive pinion.
Useasleeveonthehubofthegearthatts
inside the pinion bore. Press the gear into the
drive pinion until the gear touches the spacer.
Figure 5.13.
9. Cut two pieces of lead or solder approxi-
mately 0.5625-inch (14 mm) long and 0.625-
inch (16 mm) wide. Use the two pieces of
solder or lead as gauge blocks to determine
the correct thickness of the spacer between
the helical driven gear and the outer bear-
ing.
10. Place the two pieces of lead or solder so
that the pieces are opposite each other on
top of the helical driven gear.
11. Place the outer bearing cone into the cap
over the two pieces of lead or solder on top
of the helical driven
12.Removethesupportfromtheangeofthe
differential case. Place a sleeve on top of
the outer bearing cone. Use a press to ap-
ply 2 tons (1814 kg) of force to the outer
bearing cone. The force of the press com-
presses the lead or solder pieces to the
correct size. Do not apply more than 2 tons
(1814 kg) of force. Figure 5.14.
13. Release the pressure and remove the wood
block from under the head of the drive pin-
ion.
