Keep away from the area near the machine when tooling (H) is used to lower the machine down to the floor.
14. Put tool (H) under the front of the tracks. Start the tractor and move it forward up and on tool (H). Remove tooling (F) from under the front of the tractor. Put tool (H) under the rear of the tracks. Move the tracks to the rear up and on tool (H). Remove tooling (G) from under the rear of the tractor. Remove tool (H) from the front of the tracks. Move the tractor forward and remove tool (H) from the rear of the tracks.15. Make an adjustment to the tracks. See TRACK ADJUSTMENT in LUBRICATION AND MAINTENANCE GUIDE or SPECIFICATIONSDisassemble Tracks
1. Remove the three track shoes over the area of the track that has damage. Remove the track. See, SEPARATION OF TRACKS. Put both ends of the track on 6 in. (15.2 cm) wood blocks.
As the track assembly is disassembled, do not cause damage to the parts. Put all of the parts in a position so the ends of the bushings, the thrust rings, pins and seals can not be damaged.
2. Push the track pin part of the way out of the track assembly with tooling (A).3. Check the track pin for a groove (wear step) caused by wear. If the track pin does not have a groove (wear step), remove it all of the way out of the track assembly. If the track pin has a groove (wear step), push the track pin out 2/3 of its length.
Do not remove the track pin all of the way. Damage to the pin bore and link will be the result.
4. Remove tooling (A). Make a separation of the track pin with a cutting torch. Hit the short end of the track pin with a hammer until it is inside the bushing.5. Remove the next track pin. 6. Put tooling (B) between the track links as shown. Push the links away from each other enough to make a separation of the track chain.
Use shim stock to protect the face of the seals when the track chain is pulled apart.
7. Remove thrust rings (1) from the links. 8. Remove the link, bushing (2) and link (3) with tooling (C). 9. Remove bushing (4) from the link with tooling (C).10. Remove the seals from the links. If either seal or bushing has damage, use new parts for replacement. Do not use parts from another track assembly.Assemble Tracks
Check all of the parts of the track assembly for wear and damage. Make sure the parts are clean and dry. Check the thrust rings for wear. New thrust rings are .437 .002 in. (11.1 0.05 mm) thick. 1. Put 1P3484 Pin Adapter (2) from tooling (A) in the frame (1) of the press arrangement with the counterbore toward the ram as shown. 2. Push bushing (4) into link (3) with tooling (A). Push the bushing until it makes contact with the pin
