Note: Bearing (12) has a flange.

5. Lower the temperature of bearing (12) .

6. Use Tooling (A) and a press in order to install bearing (12) in the outside bore of the carrier roller. The outside bore can be identified by three threaded holes (H) in the track carrier roller.

7. Install the bearing until the flange on the bearing contacts the counterbore in the track carrier roller.

8. Install the new O-ring seal in the collar. Apply clean oil on the O-ring seal.

9. Use a press to install collar (11) on shaft (8). Install collar (11) until dimension (X) is 129.2 ± 0.2 mm (5.09 ± 0.01 inch).

10. Use the following procedure to determine shaft end play.

    Note: Do not install the Duo-Cone seals in the track carrier roller or collar (11) at this time.

    1. Install shaft assembly (8) in the track carrier roller without the Duo-Cone seals.

    2. Install retainer (7) and socket head bolts (6) on the end of shaft assembly (8) .

    3. Use Tool (C) to measure the end play of shaft assembly (8) .

    4. The end play of the shaft assembly must be 0.20 mm (0.01 inch) to 0.75 mm (0.03 inch). Bearing (12) controls the amount of shaft end play.

    5. Disassemble the track carrier roller, but do not remove collar (11) from shaft (8) .

Note: The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, apply clean SAE 30 oil on the contact surfaces of the metal seals. For more information concerning the assembly and installation of Duo-Cone Seals, refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install" in this manual.

17. Install cover (3) on the track carrier roller and three socket head bolts (1) .

Note: There are two types of carrier rollers: The rollers are welded or the rollers are cast. The rollers that are welded will have a weld bead. The rollers that are cast will have no welds.

18. Put the track carrier roller in a vertical position.

19. The capacity of the welded track carrier roller is 120 ± 5 mL (4.08 ± 0.17 oz). The capacity of the cast track carrier roller is 85 ± 5 mL (2.89 ± 0.17 oz).

20. Fill the track carrier roller with clean SAE 30 oil.

21. Apply a thin coat 5P-3413 Pipe Sealant on the threads of plug (2) .

22. Install plug (2) .

End By: Install the track carrier rollers. Refer to Disassembly and Assembly, "Track Carrier Roller - Install" in this manual.
