TE9000 / 93000 Service
Inspect the rollers, bearing cage and raceway for damage and debris.
Re-grease the inner bearing to supplement the grease lost during the
removal of the oil seal. Be certain to work the grease deep into the cage
and rollers.
Check the raceway for any damage before the inner bearing cone is
replaced.
Press the inner bearing fully home into the cup as this helps the location
of the oil seal driver.
Fit the oil seal onto the driver (Meritor Part No. 21221510), note that the
oil seal cannot be fitted successfully without the correct driving tool.
Make sure the 'oil side' is facing away from the face of the driver
with the outer face of the seal fully seated. Failure to seat the seal in
this way can cause the seal to be fitted skew.
Locate the nose of the driver into the inner bearing cone and drive the seal
home (fig. 18). Check that the outer most rubber edge of the seal is
flush with the face of the hub all round.
OUTER BEARING:
Remove the retaining clip, washer and outer bearing cone (fig. 17). Similar
to the inner bearing, check the condition replacing any grease lost by
working grease deep into the bearings rollers and cage.
Check the raceway for damage and the hub cavity fill before replacing the
outer bearing.
Fit the retaining washer and clip to hold the cone in place ready for re-
mounting the hub.
20B. 3 YEAR/300,000 KM MAJOR HUB SERVICE
Remove the retaining clip, washer, inner and outer bearing cones (figs 17
and 18) and clean off all grease to inspect the bearings. Do not use water,
steam or air jets to clean the bearings.
Wipe clean the hub cavity removing all the old grease and any debris. All
surfaces must be totally clean.
Look carefully for:-
Cage damage
Corrosion on the raceways/rollers
Metallic debris
Pitting
Metallic flakes
Damage to rollers/raceways
Bearings must be replaced if there are any of the above defects. Small
defects will propagate and lead to bearing failure.
If there are any discoloured bands on the rollers and raceways inspect the
bearing very carefully. It can be an indication of some of the defects
FIG. 17 described above. Treat with extreme caution if the grease smells burnt.
If there is any doubt about the condition of a bearing discard and fit a new
one.
Always replace cup and cone together.
ALWAYS USE GENUINE ROR BEARINGS – STANDARD ISO BEARINGS
CANNOT BE USED.
Check the bearing cups are hand tight within the hub bores. If a cup is
loose the hub must be replaced.
Following a complete hub and bearing clean down use a 400ml tube of
Meritor Hub Grease Blue Lithium EP2 which is sufficient to re-lubricate
both the inner and outer bearings and the hub cavity.
