(See Torque Specifications)

1. Install differential bearing cones onto hub of

support cases.

NOTE: To protect bearings during the following steps.
install bearing cups on bearing cones.
2. Apply lubricant to thrust washer surface and install

in differential support case.

3. Install differential assembly into differential support

case. Rotate differential assembly to assure proper
installation.

4. Install ring gear on differential support case,

aligning bolt holes. Make sure ring gear is seated.

NOTE: If old ring gear is used, make sure match marks
are aligned.
5. Lubricate and install the four planetary gear shafts

in the holes of the differential subassembly. Place
the planetary gears in position on the planetary
gear shafts.

NOTE: Remove any burrs from planet gear mounting
plate.
6. Position the planetary gear mounting plate on the

planetary gear shafts and dowels,

with the cham-

fered teeth facing the planet gears

. Tap the plate

with a soft hammer, if necessary, to seat the plate
against the differential subassembly.

NOTE: Be sure that the planetary gear shafts and dowel
pins are flush to below flush prior to installing thrust
plate.
7. Apply lubricant to each side of the differential

thrust plate and position the thrust plate on the
planetary gear mounting plate.

8. Place the support case on the ring gear and line up

the bolt holes. If old ring gear is used make sure
match marks are aligned.

NOTE: See Pg. 26 for M230-T export model assembly
instructions of ring gear bolts and retainers.
9. Install and tighten the ring gear bolts alternately

and evenly. Torque bolts to:

G Model 110-125 Lb-Ft (149-169 N-m)

M Model 160-180 Lb-Ft (217-244 N-m)
