Use tool (A) to install the toric ring and seal ring (6) on shaft (8). Install the ring until tool (A) makes contact with the end of the shaft.
Illustration 5 g00523424
Use a depth micrometer (11) to measure the distance between seal ring (6) and the shaft. Measure the distance at four locations that are separated by 90 degrees. The difference in these measurements must not be more than 0.8 mm (0.0315 inch).
If adjustments to seal ring (6) are necessary, use tool (A) to adjust the seal ring on the shaft.
Repeat Steps 5 through 7 for installation of the toric ring. Also, install the seal ring on the other side of the track roller.

Lubricate the O-ring seal on the seal ring with isopropyl alcohol.
Position the O-ring seal and seal ring (4) in retainer (1). Use tool (A) to install the seal ring in the retainer. Install the O-ring seal and seal ring (4) until the O-ring seal makes contact with the bottom of the retainer.
Use depth micrometer (11) to measure the distance from the surface of the retainer to the surface of seal ring (4). Measure the distance at four locations that are separated by 90 degrees. The difference in these measurements must not be more than 0.08 mm (0.0315 inch).
If adjustments to the seal ring are necessary, use tool (A) to adjust the seal ring in the retainer.
