TS5,19,64
Start By:
a. separation of tracks
1. Remove the oil from the final drive housing.
2. Remove bolts (1) and locknut (2).
3. Remove nut (3) from the sprocket shaft.
Typical Example
4. Install tooling (A) as shown. Make sure there is 6.35 mm (.250 in) clearance between 6F8343 Adapter (5) and sprocket hub (4). Fasten a hoist to tooling (A). Loosen sprocket hub (4) from the sprocket shaft.
 |
Do not remove 6F8343 Adapter (5) of the sprocket hub can fall when the tooling is removed. |
 |
5. Remove tooling (A) except for 6F8343 Adapter (5). Fasten a hoist to the sprocket hub as shown. Remove 6F8343 Adapter (5) from the sprocket shaft. Remove sprocket hub (4). The weight is 52 kg (115 lb).
6. Remove gasket (6) from the hub.
Typical Example
7. Remove outer half of Duo-Cone seal (7) from the sprocket hub.
8. Remove inner half of Duo-Cone seal (8) from the retainer.
Install Sprocket Hubs
TS5,19,61,66,71
NOTE: The rubber seals and all surfaces that make contact with the seals must be clean and dry with no damage to the surface. After installation of the seals, put oil on the contact surfaces of the Duo-Cone seals.
NOTE: See the topic, Installation Of Conventional Duo-Cone Seals, before installing any of the Duo-Cone seals.
1. Install the inner half of the Duo-Cone seal in the retainer with tool (B).
Typical Example
2. Install the outer half of the Duo-Cone seal in the sprocket hub with tool (B).
| NOTICE |
|---|
The splines in the sprocket hub and shaft must be clean and free from burrs. |
3. Fasten a hoist to the sprocket hub. Put sprocket hub (4) in position on the sprocket shaft.
Typical Example
4. Install tooling (C) and fasten a hoist. Use tooling (C) to install the sprocket hub on the sprocket shaft with a force of 311 to 355 kN (35 to 40 ton).
5. Use tooling (D) to check the distance from the shoulder of the sprocket shaft to the face of the sprocket hub. The distance must be 3.00 ± 0.8 mm (.118 ± .03 in).
6. Install gasket (6).
7. Install nut (3) that holds the sprocket hub on the sprocket shaft. Tighten the nut to a torque of 334 ± 33 N·m (243 ± 24 lb ft)
8. Put 7M7260 Liquid Gasket Material between the locknut (2) and the sprocket hub face. Install locknut (2). If the bolt holes do not make an alignment with the holes in the sprocket hub, turn nut (3) clockwise only enough to install locknut (2).
9. Fill the final drive housing with oil to the correct level. See the Operation And Maintenance Manual.
