NOTICE
The bearing in track roller (9) can be damaged when shaft (8) is installed in the track roller.

2. Fasten a hoist to shaft (8). The weight of the shaft is 19 Kg (41 lb). Carefully position the shaft in track roller (9) .

   Note: Before you install Duo-Cone seals (4) and (6) see the topic "Duo-Cone Inverted Seals - Install" in this module.

3. Put toric stabilizers (7) in position on both ends of shaft (8) .

4. 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.

5. Use a depth micrometer to measure the distance between seal ring (6) and the shaft. Make the measurements at four locations at 90 degree intervals. The difference in these measurements must not be more than 0.80 mm (.031 inch).

6. If adjustments to the seal ring (6) are necessary, use Tool (A) to adjust the seal ring on the shaft.

7. Repeat Steps 4 through 6 in order to install the toric ring and the seal ring on the opposite side of the track roller.

8. Use Tool (A) to install the O-Ring seal and seal ring (4) in position in retainer (1). Install the O-Ring seal and seal ring (4) until the O-Ring seal makes contact with the bottom of the retainer.

9. Use a depth micrometer to measure the distance from the surface of the retainer to the surface of seal ring (4). Make the measurements at four locations at 90 degree intervals. The difference in these measurements must not be more than 0.30 mm (.012 inch).

10. If an adjustment to the seal ring is necessary, use Tool (A) to adjust the seal ring in the retainer.

11. Put O-Ring seal (5) in position in the groove in retainer (1) .

12. Put 1U-6396 O-Ring Assembly Compound on the O-Ring seal. The assembly compound helps keep the seal in place on the retainer.

13. Make sure that the faces of the seal rings are clean and free of any foreign material.

14. Put a thin film of clean oil on the face of the seal rings.

15. Put Tool (B) in position in the bore of retainer (1) and the seal ring. Use Tool (B) to put the retainer and the seal ring in the original position on the track roller.

16. Use Tool (B) to hold the seal ring and retainer (1) in the correct position. Install bolts (3). Tighten the bolts evenly in order to keep the retainer in alignment with the track roller. Tighten the bolts to a torque of 135 ± 15 N·m (100 ± 10 lb ft).

17. Repeat Steps 8 through 16 in order to install the retainer on opposite side of the track roller.

18. Use Tool (C) to pressure test the track roller. Use the following procedure.

    1. Put air under a pressure of 280 kPa (41 psi) in the roller shaft. The air must be free of water.

    2. If there is a pressure reduction in ten seconds or less, there is a leak in the track roller. The track roller must be disassembled and checked.

19. Use Tool (D) to check the end play of shaft (8). The end play must be 0.25 to 0.85 mm (.010 to .033 inch).

20. Fill track roller shaft (8) with 500 mL (17 oz) of SAE 30W oil.

21. Put clean oil on the stopper. Install the stopper in the end of shaft (8). Install the stopper to 10 ± 4 mm (.393 ± 0.16 inch) below the surface of end of the shaft.

22. Use Tool (E) to install the plug in the stopper. Install the plug so that the plug is flush with the surface on the end of the stopper.

End By: Install the track rollers.
