To make the modifications, see the Tool Guide, Undercarriage Tools, Group 4, Page 2. Track Disassembly
1 Put the damaged part of the track on 6" (152.4) blocks; use the 5P2380 Track Tool Arrangement to push the pin out far enough to inspect for a wear step. If there is no wear step, completely remove the track pin. If the track pin does have a wear step, push the pin out two-thirds of its length. Remove the tools and cut the pin with a cutting torch, then push the remainder of the pin back into the housing. Remove the next pin.2 Put 7F9540 Hydraulic Puller (1) between the links to open the links far enough to permit separation of the track chain.3 With the 5P2380 Track Tool Arrangement, frame (2), bushing pusher (3) and ram adapter (4), remove the bushing from the link.4 Inspect the bushing and seals for damage. Remove the bushing from the other link.Track Assembly
1 Put bushing adapter (2) in frame (1) with the counterbore toward the ram. Use bushing pusher (3) and ram adapter (4) to push bushing (5) into link (6) until the bushing is at the bottom of the counterbore in pin adapter (2).2 Clean each end of bushing (7) with lint free paper and put SAE 90 oil on each end.3 Install pilot pin (8) in the bushing with the end of the pin that has a chamfer in the bushing.4 Clean thrust rings (9) and (10) and seals (11) with lint free paper; put SAE 90 oil on the seals. Install the thrust rings on pilot pin (8).5 Use the 5P2380 Track Tool Arrangement, pilot pin (8), bushing adapter (2), bushing pusher (3) and ram adapter (4) to assemble the links and bushing as shown.6 If a new pin is used, put lubricant on rubber stopper (12) and put it in 5P1725 Plug Installer. Use 5P1725 Plug Installer (13) and install rubber stopper (12) in pin (14). If the lubrication equipment is available, the pins need not be filled with oil at this time. If the equipment is not available and the plug is in rubber stopper (12), use a small punch and push the plug into the drilled passage of pin (14).
