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:

    1. Use air that is free of water in order to pressurize the track roller to 280 kPa (41 psi).

    2. 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.
