Differential Gears Rotating Resistance; Installation; Drive Pinion Into The Carrier - Meritor MS-113 Maintenance Manual

14. Install the capscrews through both differential
case halves and into the ring gear. Use a
CRISSCROSS pattern to tighten the capscrews
to 105-115 lb-ft (140-155 N•m). Figure 4.7.
15. Inspect the differential gears rotating
resistance. Use the following procedure.

Differential Gears Rotating Resistance

1. Make an inspection tool using an axle shaft
that matches the spline size of the differential
side gear. Cut the shaft to approximately
12-inches (304.8 mm). Weld a nut onto the end
of the shaft. Figure 4.8.

Assembly and Installation
2. Place the differential and ring gear assembly
in a vise. Install soft metal covers over the vise
jaws to protect the ring gear.
3. Install the tool into the differential until the
spines on the tool are engaged with one
side gear.
4. Place a torque wrench onto the nut onto the
tool and rotate the differential gears. Read the
value indicated on the torque wrench.
If the torque value is greater than 50 lb-ft
(68 N•m): Disassemble the differential case
and inspect parts for wear or damage.
Repair or replace parts as necessary.
Reassemble the differential case and repeat
Steps 2 through 4.

Installation

Drive Pinion into the Carrier

1. Install the drive pinion inner bearing cup into
the carrier.
2. Apply axle lubricant onto the carrier pinion
cage bore and inner bearing cup.
3. Apply axle lubricant onto the pinion inner and
outer cone.
4. Install the drive pinion into the inner bearing
cup in the carrier. Install the outer bearing cup
into the pinion case.
5. Coat the pinion cage seal bore with GL-5 gear
oil prior to installing the new seal. To obtain
this lubricant, refer to the Service Notes page
on the front inside cover of this manual.
6. Install a new seal into the pinion cage.
7. Install a new O-ring onto the pinion cage.
8. Apply axle lubricant on the pinion cage thread
and pilots, O-ring and outer bearing cone.
9. Place the pinion cage onto the carrier. Use
your hands to screw the pinion cage into the
carrier to verify that the cage is correctly
installed.
10. Install the yoke locknut onto the drive pinion
shaft. Do not install the yoke at this time.
