4. Check the condition of the O-ring seal that is used in collar (11). If the seal is damaged, use a new part for replacement. Install the O-ring seal in the collar. Put clean oil on the O-ring seal.

5. Use a press to install collar (11) on shaft (8). Install collar (11) until dimension (X) is 129.2 ± 0.2 mm (5.09 ± .01 inch).

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

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

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

   2. Install retainer (7) and socket head bolts (5) and (6) on the end of shaft assembly (8) .

   3. Use Tooling (C) to measure the end play of shaft assembly (8). The end play of the shaft assembly must be 0.20 mm (.008 inch) to 0.75 mm (.030 inch). Bearing (12) controls the amount of shaft end play.

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

Note: Refer to Disassembly and Assembly Manual, "Duo-Cone Conventional Seals - Install" for more information.

Note: The rubber seal 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.
