1. Fasten tooling (A) to the master links and sprocket as shown. 2. Move sprocket forward until the track is pulled up on the sprocket and the end of the track is forward of a vertical line through the center of the sprocket as shown. Remove tooling (A). 3. Install tool (B) between the first bushing in the link and the sprocket.4. Move the sprocket forward. Use tool (B) to guide the track over the track carrier roller and front idler. 5. Put tool (C) in position under the track shoe that is below the master shoe as shown.6. Move the track forward until the master links (1) are in alignment. 7. Put master shoe (2) in position on the master links as shown. Put 9M3710 Anti-Sieze Compound on the threads of the bolts that hold the master shoe. Install the four bolts and tighten to a torque of 180 30 lb.ft. (250 40 N m). Tighten the bolts 180° more.8. Tighten the relief valve to a torque of 25 5 lb.ft. (35 7 N m). If the fill valve was loosened, tighten it to a torque of 25 5 lb.ft. (35 7 N m). 9. Make an adjustment to the track. See TRACK ADJUSTMENT in D4E TRACTOR POWER TRAIN SPECIFICATIONS.Disassemble 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 as protection for 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,
