This guide covers Caterpillar D6M-LGP machines with serial prefixes 2RN, 4GS, 4JN, and 5NR converting from SystemOne to conventional swamp undercarriage.

A SystemOne to swamp conversion replaces the sealed SystemOne undercarriage with a conventional track setup using specialized 34" swamp-style track shoes. This is a full undercarriage conversion that requires replacing all mating components simultaneously — track chain, swamp shoes, lower rollers, top carrier rollers, idlers, sprocket segments, and recoil springs. The swamp shoe configuration provides greater flotation for operation in wet or soft ground conditions.

A complete CAT D6M-LGP SystemOne to swamp conversion requires 2 conventional 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. All components must be replaced at the same time since SystemOne and conventional parts are not interchangeable.

The CAT D6M-LGP SystemOne to swamp conversion 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.

No. SystemOne and conventional undercarriage components are not interchangeable. A full conversion to swamp track requires replacing all mating components simultaneously — track chain, swamp shoes, rollers, idlers, and sprocket segments. Attempting a partial replacement will result in incompatible components and accelerated wear.

After converting your CAT D6M-LGP to conventional swamp track, the chain and hardware specifications are: Pitch 7.50", Bolt Diameter 3/4", Link Height 119mm, and Bushing Outside Diameter (O.D.) 65.0mm. The swamp configuration uses the same chain and hardware as the standard conventional setup, differing only in track shoe style.

Track hardware is typically sold separately. When installing swamp track shoes as part of a D6M-LGP SystemOne to swamp conversion, you will need the appropriate track bolts and nuts. It is recommended to use new hardware throughout the conversion.
