FIT NEW AUXILIARY OIL SEAL

Apply 15 - 20gm of Meritor Hub Grease, Blue Lithium EP2 to the
cavity of the new seal, working the grease in evenly around the
circumference of the seal.
Apply a light smear of Meritor Hub Grease, Blue Lithium EP2 to
the bore of the oil seal.
Press the new oil seal onto the oil seal driver (Meritor CVA part
No.MST 3106) ensuring the 'oil side' marking on the seal is visible
(i.e. faces away from the plate of the driver) such that the seal will
be installed the correct way round in the hub.
Locate the nose of the driver into the bore of the inner bearing
cone and drive the seal fully home ensuring the seal remains
square to the hub at all times (Fig. 4.23). The seal will bottom out
on the inner hub shoulder and the outer face will remain proud of
the hub when fully installed.

LC Hub Re-fitment Procedure

CLEAN SPINDLE BEARING JOURNAL

Prior to re-assembling the hub onto the spindle, check the spindle
for damage and remove any fretting or rust on bearing journals
using medium grade emery cloth strip. Also ensure the inner
bearing abutment shoulder is clean and free from damage.
Clean the oil seal journal, removing brake dust or corrosion from
adjacent areas.

CHECK SPINDLE END THREAD
Any minor damage can be repaired using a die nut and holder
(Meritor CVA part numbers MST 3108 and MST 3109).
Apply 1 to 2 grams (volume 1 to 1.5 cm
White Paste T' to the axle spindle in the area 'A' (Fig 4.24). Refer
to Section 11 Lubricants for the Meritor CVA Optimol part
numbers.
Spread the grease evenly around the spindle's circumference
using a suitable soft brush. Using the excess grease on the brush,
apply an even film around the circumference of the bearing journal
shoulder, area 'B' (Fig 4.24). This will reduce spindle wear and
assist future removal of the hub assembly.
CAUTION
: If the quantity of Optimol White Paste
exceeds 2 grams in area 'A', there is a risk that the
end clamp load will relax, resulting in a loose end nut.

Ensure the hub bearing bores are clean and free from any excess
grease.
Apply 0.5 to 1 grams of Optimol 'Optimoly White Paste T' to the
outboard bearing bore only and spread evenly around the
circumference. Refer to Section 11 Lubricants for the Meritor
CVA Optimol part numbers.
CAUTION:
Only use the grease supplied with
replacement components/kits, or that specified.
Under no circumstance should any other type of grease be
used.
