Apply Anti-Fretting Paste To Spindle; Refit Hub, Drum And Wheel Assembly - Meritor TE9000 Service Service Manual

TE9000 / 93000 Service
Dry the bearings of any solvent used for cleaning the bearings.
Thoroughly re-pack the inner and outer bearings with grease. Work the
grease deep into the rollers with your hands until the cages are solid
packed with grease. Always place greased bearings in a clean area
and protect from falling debris.
Press the inner bearing fully home into the cup. (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' (written on the rubber) is facing away from
the face of the driver, with the outer face of the seal fully seated on
the face of the driver. 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.
Replace the greased outer bearing.
Fit the retaining washer and clip to hold the cone in place until you are
ready to remount the hub.
Fill the empty cavity of the hub with the grease left in the 400ml tube. Do
not over fill with extra lubricant.

21. APPLY ANTI-FRETTING PASTE TO SPINDLE

Apply 'Optimol White Paste T' to both the inner and outer bearing journals,
approximately 1-2ml per journal. Smear the paste evenly over the bearing
areas and up the inner bearing abutment shoulder (fig. 19).
This paste will reduce wear and ease the removal of the bearing cones
during future maintenance.

22. REFIT HUB, DRUM AND WHEEL ASSEMBLY

Using a wheel dolly align hub, drum and wheel assembly with the axle
spindle, adjust position and height until brake drum fits over brake linings.
If the outer bearing is removed be certain to place it in a clean area before
it is reassembled in the hub.
To mount the hub assembly without the outer bearing, retaining washer
and clip in place, push assembly fully onto axle and guard against striking
the oil seal on the spindle end, replace the oil seal if any damage occurs.
Fit the outer bearing cone. Fit the outer bearing retaining washer with the
writing outer most and fit retainer clip.
If the outer bearing is still in place check alignment and height and align
key on retainer washer with key way on spindle end, gently push the
assembly fully onto the axle, guard against striking the oil seal on the
spindle end, replace the oil seal if any damage occurs.
Carefully examine the tabs and keyway locater for signs of wear or
damage, if any doubt exists use a new tab washer. Fit tab washer locating
in key way on spindle end, fit axle end nut hand tight and remove wheel
dolly.

Torque axle end nut to 150/175 Nm. Whilst tightening axle end nut rotate
wheel several times to seat wheel bearings (fig. 3).
Never torque the final stages of the end nut without rotating the hub.
Failure to do this can cause bearing damage and result in the hub
not seating properly.
Bend tab washer tab closest to a full flat on the end nut using a suitable
tool (Meritor Part No. 21221514).
Check the hub cap mounting face and gasket groove is free of debris and
damage, wipe clean the mounting faces.
Fit hub cap gasket (Meritor Part No. 21223797) to the hub cap with the
flat face of the seal against the cap. A 'smear' of grease within the
external hub cavity and on the back of the hub cap is good practise to
prevent corrosion in the event of any moisture ingress.
Fit hub cap and gasket to hub, tighten hub cap screws sequentially
observing the compression of the gasket around the fixings, finally torque
hub cap screws to 11/15 Nm (fig. 1). Over tightening will split the gasket.
Too little pressure on the gasket may not provide an effective seal.
