Power Train Disassembly & Assembly
Wear safe clothing and gloves for protection from
injury when working with the hot ring gear.
2. Safely lift the ring gear from the tank of water
using a lifting tool.
3. Install the ring gear on the flange case half
immediately after the gear is heated. If the ring
gear does not fit easily on the case half, heat the
gear again. Repeat step 1.
4. Align fastener holes of the ring gear and flange
case half. Rotate the ring gear as needed.
5. If rivets were used to hold the ring gear to the
flange case half, replace them with bolts, nuts and
washers.
6. Install the bolts, nuts and washers that hold the
ring gear to the flange case half. Install the bolts
from the gear side of the assembly. The bolt
threads must be installed from the inside face of
the ring gear. The nuts with washers are tightened
from the back of the ring gear.
7. Tighten the bolts and nuts to a torque of 196 to
262 lb•ft (265 to 355 N•m)
a. After the bolts are installed, inspect for gaps
between the back surface of the ring gear and the
case flange. Use an 0.080 mm (0.003 inch) feeler
gauge and inspect at four points around the
assembly.
b. Inspect the flange case half and ring gear for the
problem that causes the gap. Repair or replace
parts.
c. After the parts are repaired or replaced, assemble
the ring gear on the flange case half. Repeat this
procedure starting on page 28, and these steps a
through c.
8. Install the bearing cones on both of the case
halves. Use a press and sleeve of the correct size.
