9. Make adjustment to fthe track as follows:a. Move the machine forward for a distance that is two times the length of the machine. Let it come to a stop without the use of the brakes.b. Put a tight line between the grouser tips at the sprocket and front idler.c. Measure distance (X) from the line to the lowest point of (sag) of the grouser tips. Put 5P960 Multipurpose Grease in the track adjuster and adjust the track until distance (X) is 140 10 mm (5.5 .4 in.). This is the sag (curve) in the track between the sprocket and the front idler.d. Do not tighten the track more if distance (Y) is 165 mm (6.5 in.) or more. The track will have to be removed and reconditioned. 10. Install the track adjuster cover (1) and O-ring seal (10) on the roller frame.Disassemble Tracks
1. Put the track pin to be removed in position behind the front idler.2. Put blocks (3) in position under the front of the track.3. Put blocks (2) in position under the track to keep the track away from the track roller frame when the pressure is released in the track adjuster.4. Release the pressure in the track adjuster. See Separation Of Tracks.5. Put tool (A) in position as shown. Use tool (A) to keep the track in position when the track pins are removed.6. Remove the bolts, and use two persons to remove four track shoes (1) over the track pins to be removed. 7. Fasten a hoist to tooling (B). Put tooling (B) in position against the track pin.8. Push the track pin out of the track with tool (B), and install tool (C) to hold the track together until the other track pin is removed.9. Put tooling (B) in position against track pin (4). Push track pin (4) out of the track, and install tool (C). Remove tooling (B) from the track. 10. Put tooling (D) in position between links (5) and (6). Use tooling (D) to spread the links apart far enough to move link (7) away from links (5) and (6).11. Remove tooling (C) from links (5), (6) and (7).
Do not damage the face of the seals when the links are moved apart.
12. Fasten a hoist to link (7). Move the link away from links (5) and (6). Put a block under link (7) to keep it away from links (5) and (6). 13. Put tooling (D) in position between links (8) and (9). Use tooling (D) to spread the links apart far enough to remove link assembly (10).14. Fasten a hoist to link assembly (10).15. Remove tool (C) from links (8) and (9) and link assembly (10), and remove the link assembly. The weight of the link assembly is 31 Kg (68 lb.). 16. Remove seal assemblies (11) from links (5) and (6). 17. Put the link assembly in position in tooling (E) as shown.18. Remove link (6) from the bushing with tooling (E).19. Remove the other
