What makes the CAT D6M-LGP swamp undercarriage different from the standard conventional setup?
The D6M-LGP swamp configuration uses specialized 34" swamp-style track shoes (OEM 1070715) instead of standard single grouser shoes. Swamp shoes have a wider, flatter profile that distributes machine weight over a larger surface area, providing greater flotation in soft, muddy, or wet ground conditions. All other undercarriage components — track chain, rollers, idlers, sprockets, and recoil springs — are the same as the standard conventional setup.
What is included in a complete CAT D6M-LGP swamp undercarriage rebuild?
A complete CAT D6M-LGP swamp undercarriage rebuild requires 2 track chains, 90 swamp-style track shoes per side, lower rollers (quantity varies by position), 2 top carrier rollers per side, 2 idler assemblies, 2 sprocket segment groups, and 2 recoil springs. The key difference from a standard rebuild is the use of 34" swamp-style shoes instead of standard grouser shoes.
What track shoe is used on the CAT D6M-LGP swamp configuration?
The CAT D6M-LGP swamp configuration uses a 34" swamp-style track shoe (OEM 1070715). This shoe has a wider, flatter profile than standard single grouser shoes and is designed for operation in wet, muddy, or soft ground conditions where maximum flotation is required.
What should be inspected when replacing CAT D6M-LGP swamp track chains?
When replacing your CAT D6M-LGP track chains on a swamp-configured machine, inspect the swamp track shoes, sprocket segments, lower rollers, top carrier rollers, and idlers. Replacing worn mating components at the same time helps maximize the lifespan of your new track chains and prevents premature wear.
What are the track specifications for the CAT D6M-LGP swamp undercarriage?
The track specifications for the CAT D6M-LGP swamp undercarriage are the same as the standard conventional setup: Pitch 7.50", Bolt Diameter 3/4", Link Height 119mm, and Bushing Outside Diameter (O.D.) 65.0mm. The swamp configuration differs only in track shoe style, not in chain or hardware specifications.
Are track bolts and nuts included with CAT D6M-LGP swamp track shoes?
Track hardware is typically sold separately. When replacing Caterpillar D6M-LGP swamp track shoes, you will need the appropriate track bolts and nuts. It is recommended to use new hardware when installing new track shoes to ensure proper torque and retention.
