carbon dioxide, or dry ice, freezing of the cup is used,
remember to permit the cup and hub to warm to
ambient temperature after insertion and then to tap
them with a soft steel drift and hammer to seat.
2. Lubricate inner bearing cone (4) with lubricant
specified in Section 300-0020, LUBRICATION
SYSTEM and install in wheel (6). Place washer (3) on
bearing, drive or press new seal (2) into position, and
install snap ring (1). Install seal with lip towards
bearing. Apply a light coat of gear oil to seal lips and
special seal bushing on spindle.
Note: If new 'Buna' seal is used, be sure it is installed
in thewheel bore with the dirt seal (square lip) toward
the machine frame. Pack seal valley with EP grease.
Install snap ring (1).
3. If removed, install brake drum on wheel (6) and
secure with mounting hardware as removed at
'Removal'. Make sure brake drum and wheel (6) are
clean where they contact each other, so that the drum
will run true.
4. Wrap spindle threads carefully with masking tape to
protect the seal and threads. With suitable lifting
equipment slide wheel (6) and drum assembly onto the
spindle carefully to avoid damaging spindle threads.
Remove protective tape from spindle threads.
5. Lubricate outer bearing cone (9) with lubricant
specified in Section 300-0020, LUBRICATION
SYSTEM. Install outer bearing cone (9) on spindle and
seat in outer bearing cup (5).
6. Apply a smear of oil or grease to the threads of
spindle and install spindle nut (10) on spindle. Make
sure nut turns freely for full thread length. If nut binds,
either replace with new nut or chase the threads so
nut will turn freely.
7. Attach fishtail assembly (See Special Tools) to
wheel (6) assembly and fabricated tool assembly
across wheel (6) assembly, as described during
disassembly.
8. Rotate wheel (6) assembly and tighten spindle nut
(10) to a seating torque of 1 360 Nm (1 000 lbf ft), or
until wheel starts to bind, while rotating and bumping
wheel (6) assembly to ensure adequate seating of the
wheel bearings.
9. Back off spindle nut (10) until the wheel turns freely
(approximately 1/2 turn).
10. Start the wheel rotating and torque tighten spindle
nut (10) to 740 Nm (550 lbf ft).
Note: Always rotate wheel when tightening spindle nut
(4), see Section 160-0050, WHEEL, RIM AND TYRE,
'Bearing Adjustment', for explanation.
11. Secure spindle nut (10) with screws (11).
12. Install planetary gear assembly and fill planetary
and differential assemblies with lubricant specified in
Section 300-0020, LUBRICATION SYSTEM. Refer to
Section 160-0040, PLANETARY GEARING.
13. Install tyre on wheel as described under 'Mounting
Tyre on Wheel'.
TYRE INFLATION
WARNING
To prevent personal injury and property
damage, the tyre and rim assembly should be
placed in a safety cage before inflating. If no
safety cage is available or tyre is on the
machine, the tyre and rim assembly should be
wrapped with safety chains or with lash cables
before inflating.
Even with these precautions remember that
air-blast is a potential hazard. Tyre inflation
should be carried out away from busy working
areas.
WARNING
To avoid personal injury and property damage,
never stand or sit in front of a mounted tyre
during tyre inflation. Use a clip-on air chuck
with a long hose and stand to one side while
the tyre is being inflated.
WARNING
To prevent personal injury and property
damage, always prevent flammable vapours
that could produce tyre explosions, from being
pumped into tyres during inflation, by
observing the following precautions:
A.
Use an air compressor and reservoir located
inside a heated building, when available, so
that alcohol, methanol, or other flammable
antifreeze liquids are not needed in the air
tanks to prevent moisture freezing in the tank
and lines in subfreezing outside temperatures.
