Meritor Maintenance Manual MM-15103 (Issued 07-17)
When you turn the adjusting rings, always use a tool that
engages two or more opposite notches in the ring. An
adjusting ring tool can be used for this purpose. If the tool does
not correctly fit into the notches, damage to the lugs will occur.
2. Use an adjusting ring tool to loosen the adjusting ring that is
opposite the ring gear. A small amount of end play will show on
the dial indicator. Figure 5.59.
Figure 5.59
3. Use one of the following methods to move the differential and
the ring gear carefully to the left and right while you read the
dial indicator.
A. Insert two pry bars between the bearing adjusting rings
and the ends of the differential case. The pry bars must
not touch the differential bearings. Figure 5.60.
B. Insert two pry bars between the differential case or the
ring gear and the carrier at locations other than described
in Step A. The pry bars must not touch the differential
bearings. Figure 5.61.

4. Tighten the bearing adjusting ring until the dial indicator reads
ZERO end play. Move the differential and ring gear to the left
and right as needed. If necessary, repeat Step A or Step B.
5. Tighten each bearing adjusting ring one notch from ZERO. The
side bearings of the differential should have a preload of
15-35 lb-in (1.7-3.5 N폷m). Figure 5.62.
@
This procedure should expand the caps 0.002-0.009-inch
(0.05-0.23 mm), and place the correct preload on the bearings
when they are installed into the banjo housing.
