------ WARNING! ------

Personal injury or death can result from grease and oil coming out of the relief valve.

Grease and oil are under high pressure coming out of the relief valve and can penetrate the body.

Do not watch the relief valve to see if grease is escaping. Watch the track or track adjustment cylinder to see if the track is being loosened.

Make sure the vent holes are clean before the tension is released on the track.


------ WARNING! ------

Personal injury can result from the track coming off of the roller frame.

The track can move off the track roller frame very quickly when a separation of the track is made.

Keep away from the front of the machine when the track is removed from the track roller frame.


  1. Put the machine on a flat, level surface.

  2. Position the master pin in a horizontal line through the center of the idler.

  3. Release the tension on the track assembly. Refer to Operation and Maintenance Manual, "Track Adjustment - Adjust" for the proper procedure.

    Note: The two track bushings may fall out of the track links when the track assembly is separated.

  6. Remove cotter pin (4) from the master pin. Use a hammer and a punch to remove master pin (3) from the track links. Separate the track links, and locate the two track bushings.

  7. Attach a suitable lifting device to the track assembly. Raise the track assembly off Tooling (A). Remove Tooling (A) from the track assembly and lower the track assembly to the floor.
