shaft (7) .

4. Lubricate the bore of rim assembly (6) lightly with SAE 30W oil. Lubricate the outside
surface and seal of bushing assembly (10) lightly with SAE 30W oil. Use a press and
Tooling (C) to install bushing assembly (10) in rim assembly (6). Bushing assembly (10)
should just clear the retaining groove in rim assembly (6) .
5. Use Tooling (A) to install retaining ring (5) in rim assembly (6) .
NOTICE
The bushing assembly that is in track roller (6) can be damaged when
shaft (7) is installed in rim assembly (6). Use care when you position
shaft (7) .

6. Rotate the track roller assembly by 180 degrees. Install track roller shaft (7) in rim assembly
(6) .
7. Lubricate the bore of rim assembly (6) lightly with SAE 30W oil. Lubricate the outside
surface and seal of bushing assembly (10) lightly with SAE 30W oil. Use a press and
Tooling (C) to install remaining bushing assembly (10). Bushing assembly (10) should just
clear the retaining ring groove in rim assembly (6) .
8. Use Tooling (A) to install retaining ring (5) in rim assembly (6) .

Note: For information about Duo-Cone seals, refer to Disassembly and Assembly, "Duo-
Cone Conventional Seals - Install" for the machine that is being serviced.
10. Use Tooling (B) to install Duo-Cone seal assembly (4) in end collar (1) .

11. Install end collar (1) and lock ring (3) on track roller shaft (8) .
12. Repeat Steps 10 and 11 in order to install the remaining end collar (1) on the opposite end of
track roller shaft (8) .
13. Use Tooling (D) to pressure test the track roller by using the following procedure:
a. Use air that is free of water in order to pressurize the track roller to 280 kPa (41 psi).
b. Observe the pressure reading of the track roller. The pressure reading should remain
constant for ten seconds. A reduction in pressure in ten seconds or less indicates a
leak in the track roller. In the event of a leak, the track roller must be disassembled
and checked.
Typical example
14. Use Tooling (E) to check the end play of shaft (8). The end play should be 0.25 to 1.33 mm
(0.010 to 0.052 inch).
