Assembly Procedure for the Track Carrier Roller on CIPI Undercarriage Arrangements which are Based on 330 and 330B Track Type Excavators

Reference: Refer to Undercarriage Reconditioning Bulletin, SEBF8568, "Hydraulic Excavator Roller Disassemble and Assembly Procedures" for the disassembly and assembly procedures for the track carrier roller.

1. Thoroughly clean all of the parts of the track carrier roller prior to assembly.

Note: Do not reuse bearings (12) and (13). Use new parts for replacement.

Note: Bearing (13) is a straight bearing.

2. Lower the temperature of bearing (13). Use Tool (A) and a press to install bearing (13) in the inside bore of the carrier roller. Install the bearing until the bearing is even with the shaft counterbore in the carrier roller.

Note: Bearing (12) has a flange.

3. Lower the temperature of bearing (12). Use Tool (A) and a press 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. Install the bearing until the flange on the bearing contacts the counterbore in the track carrier roller.

4. Check the condition of the O-ring seal that is used in collar (11). If the O-ring seal is damaged, use a new part for replacement. Install the O-ring seal in the collar. Apply 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 132.4 ± 0.20 mm (5.21 ± .008 inch).

6. 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 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). The end play of the shaft assembly must be 0.25 mm (.010 inch) to 1.25 mm (.049 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: 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 Conventional Duo-Cone Seals, refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install" in this manual.

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

13. Put the track carrier roller in a vertical position. Fill the track carrier roller with 180 ± 10 mL (6.12 ± .34 oz) of clean SAE 30 oil. Apply a thin coat of 5P-3413 Pipe Sealant on the threads of plug (2). Install plug (2) .

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