Grease is under high pressure. Grease coming out of the relief valve under pressure can penetrate the body causing injury or death. 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. Loosen the relief valve only one turn.

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.

5. Use Tooling (A) to remove master pin (2) from the track assembly. Make sure that the pilot pin is installed correctly in the track assembly prior to removing Tooling (A) .

6. Start the machine and move the track assembly until pilot pin (3) is in the position that is shown.

7. Put Tool (B) under the track grouser, as shown. Move the track assembly onto Tool (B) just enough to remove the load off of pilot pin (3) .

8. Remove pilot pin (3) from the track assembly.

9. Move the machine forward in order to clear the track assembly from the undercarriage frame assembly.

10. Remove the washers and spacers from the track assembly at the master pin joint.

11. Fasten a suitable lifting device to the rear of the track assembly. Raise the track assembly, and remove Tool (B). Lower the rear of the track assembly to the floor.

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.

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

4. Remove cotter pin (3) from the master pin. Use a hammer and a punch to remove master pin (2) from the track links. Separate the track links, and locate the two track bushings. Slowly move the machine forward until the track assembly is off the sprocket, the track carrier rollers and the front idler.

5. Fasten a hoist to the rear of the track assembly. Raise the track assembly off Tool (A). Remove Tool (A). Lower the rear of the track assembly to the floor.
