TRACK CHAIN SPLIT LINK TYPE CHAINS
15 - 6
REMOVAL
1. Move machine forward until split link is on front lower half of front idler.
Relieve track tension per OPERATION & MAINTENANCE MANUAL.
Block up under shoe and remove split link bolts and shoe.
WARNING
When split link bolts and track shoes are removed, chain is free to
separate. Before disconnecting chain for any reason, be sure to re-
lieve all track adjuster pressure. This must be done for safety rea-
sons.
2. Move machine backward until sprocket is at end of chain. Place a plank
flush against rear of chain when it is flat on ground. Plank should be
approximately same thickness and width as chain and long enough so
that entire machine can rest on plank. Move machine off chain and onto
plank.
INSTALLATION
1. Position chain in front of plank with split link half with shoe surface
against plank. If chain is reversed from position shown above, severe
undercarriage wear will result. Block up front of chain. Drive machine
forward onto chain. As sprocket passes end of chain, pull chain over
sprocket and top idler. Stop machine when front idler contacts blocked
up chain.
2. Be sure machined surfaces of split links are clean. Interlock split link
halves in front of front idler. Align link side surfaces and install bolts to
check alignment. Remove bolts. Install track shoe and bolts and torque
to value given. Adjust track tension. Refer to OPERATION & MAINTE-
NANCE MANUAL
REMARK
Two methods for repairing a chain are available. One method is to repair
complete chain using a twin head table press. The other is to rebuild only
leaking joints using portable 91 mg (100 ton) track press.
COMPLETE CHAIN REBUILD
Disassembly
1. Using a slow speed drill and a 0.50 in or 12 mm drill bit, remove rubber
plugs (10) from pins (4). Position chain on press so that bushing end
(non threaded end) of split link (9 and 10) is toward rams. Remove track
shoes.
2. Install disassembly adapters on ram heads. Advance chain and lower
table so split link drops into saddle. Press pin out of right link (8), then
press pin out of left link (9). Remove loose split links from press.
3. Advance track chain so next link drops into saddle. Press pin (4) and
bushing (5) out of right link (7), then press pin and bushing out of left link
(6). Remove loose links, bushing and pin from press.
4. Repeat Step 3 with remaining sections of chain. Remove seals (11) from
chain links.
