Removal Procedure
Tools Required
J 8614-01 Pinion Flange
Holder
- Remove the bolt and retainers.
Important: Observe and mark the positions of all the driveline components, relative
to the propeller shaft and the axles, prior to disassembly. These components
include the propeller shafts, drive axles, pinion flanges, output shafts,
etc. Reassemble all the components in the exact places in which you removed
the parts. Follow any specifications, torque values, and any measurements
made prior to disassembly.
- Mark the installed position of the propeller shaft and the pinion flange.
Reassemble the propeller shaft and the pinion flange in the same position.
- Remove the propeller shaft from the pinion flange.
3.1. | Use a piece of tape to hold the bearing caps. |
3.2. | Secure the propeller shaft up and out of the way in order to not
put any stress on the universal joints. |
3.3. | Make an alignment mark on the pinion stem, pinion flange, and
the pinion flange nut. Record the number of exposed threads on the pinion
stem for reference. |
- Measure the amount of torque required to turn the pinion using an inch-pound
torque wrench. Record this measurement for reassembly. This will give combined
pinion bearing, seal, carrier bearing, axle bearing, and seal preload.
- Remove the pinion flange nut and washer.
- Use J 8614-01
in order to
hold the pinion flange.
- Remove the pinion flange. Place a container under the flange in order to retrieve
the lubricant.
- Remove the oil seal. Use a seal removal tool. Do not damage the
carrier.
- Inspect the seal surface of the pinion flange for tool marks,
nicks, or damage, such as a groove worn by the seal. Replace the flange if
necessary. Refer to
Drive Pinion Yoke Replacement
.
- Inspect the carrier bore for burrs that may cause leaks around
the outside of the seal.
Installation Procedure
Tools Required
• | J 23911 Pinion
Oil Seal Installer |
- Install a new seal using J 23911
.
- Apply seal lubricant to the outside of the pinion flange and the
sealing lip of the new seal.
Important: Do not hammer the pinion flange onto the pinion stem.
- Install the pinion flange.
- Install the washer and nut.
Tighten
• | Tighten the nut on the pinion stem to the same position as marked
in removal. |
• | Tighten the nut 1.59 mm (1/16 in) beyond the alignment
mark. |
• | Align the propeller shaft with the alignment marks made previously.
Use J 8614-01
in order to
hold the pinion flange. |
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the propeller shaft to the pinion flange.
- Install the bolts and retainers.
Tighten
Tighten the bolts to 45 N·m (33 lb ft).
