MAINTENANCE MANUAL - Meritor

Preparation for assembly
J - Remove from the pinion rod manually the
adjusting wedges of the roller bearings. (figure
32).
Cleaning
The unit can undergo external washing, in order
to facilitate its removal and disassembly. In
this case, all the openings should be covered
to avoid the possibility of water or humidity entering
the unit.
Figure 32
K - Remove, if necessary the back roller bearing
cone using an appropriate extractor or
a press (figure 33).
L - Remove and discard, if necessary, the elastic
ring, using appropriate pliers.
IMPORTANT :
We do not recommend washing the unit with
water after it has been disassembled. When
this cleaning system is used, the water is retained
in the parts. This can cause oxidation
(rust) in critical parts and allow the circulation
of these rust particles in the oil. This
practice can lead to premature wear of the
roller bearings, gears and other parts. Thuds,
the unit should be totally disas-sembled
as it cannot be cleaned suitably in another
manner.
NEVER USE GASOLINE
Wash all the components which have ma-chined
or rectified surfaces (gears, roller bearings,
wedges, crosspiece) using appropriate solvents
with a petroleum base, such as: diesel oil
of kerosene.
Wash the cast parts (satellite box, bearing covers
and inside of the differential box) using the
afore mentioned solvents. CAUTIONly remove
all the joint particles. See the LIQUIDJOINT
section.
Clean the breathing plugs CAUTIONly (an air
jet can be used). If it is blocked or damaged,
replace it.
Figure 33
M - Remove, if necessary, the pilot roller bearing,
using an appropriate press (figure 34)..
CAUTION:
Blocked plugs cause an increase in
internal pressure in the unit, being
able to lead to oil leaking by the
sealers.
