Loosen the track tension as previously described (Par. 6 (2)) by turning the adjuster counterclockwise. 3. Take out the lock wire from the master link pin. Using a heavy punch bar and sledge, drive out the master link pin as shown in lliust Back the tractor until it is at the end of the track chain. Put a plank flush against the rear of the track when the track chain is flat on the ground. Back the tractor off the track chain and onto the plank as shown in lliust. 6. The plank should be approximately the same thickness as the track chain and yet narrow enough to fit between the track roller shields, and long enough for the entire tractor to rest upon it. NOTE: If the old track chain is to be removed and replaced with a complete new chain, remove the old chain as described above and place the new chain on the ground ahead of the tractor, with the open link end flush with and against the front of the old chain. 8. TRACK CHAIN REPAIR To repair or replace worn track pins. bushings or links, a hydraulic track press will be necessary. The operation and procedure instructions for each track press will vary. so that specific disas sembly instructions will be found with the manufacturers operational instructions. For further information regarding the hydraulic track press, refer to "SERVICE TOOL" manual, ISS-I002. Interlocking Type Chain. To replace a damaged section of track. remove the track shoes. and cut out the damaged section with a cutting torch. Remove the end links as outlined in the following step: Rebuild the section onto the track by pre.ssing individual standardlinks. link pins and bushings with a hydraulic track press. When joining track sections together. master links, master link bushings. and a master link pin can be used in the coupling link; or, the section can be joined as outlined in step 2. CAUTION: When assembling the track chain, maintain.00 to.045 inch clearance between track links. A-5J70 liiust_ 5 - Removing the Master Link Pin. liiust. 6- Driving the T-ractor onto the Track Chain. END WITH BUSHING HERE \,, 2. To replace an individu~l link that is damaged, remove the track from the tractor. After the track is free and extended flat. remove three or four of the track shoes adjacent to the damaged part. Cut the pins and bushings of the damaged link with a torch. The cuts should be made as close to the inside faces of the inner links as possible (lliust. 8) to provide sufficient clearance between the links for the removal of the remaining- pin and bushing sections. CAUTION: Be careful not to damage the inner faces of the links when cutting the bushings and pins. The pieces of the pins and bushings remaining in the links must now be securely welded together at the cuts. See lliust. 8. It is impo.rtant that the welds be strong enough to ISS (6-64)
