This guide covers Caterpillar D6M-XL conventional undercarriage machines with serial prefixes 2YS, 3WN, 4HS, 5WR, 6LR, and 9ZM.

Common replacement components for the Caterpillar D6M-XL include the Track Chain (HD TLA SALT, OEM 1102976), Track Shoes (22" or 24"), Lower Rollers — Single Flange (OEM 1210824) and Double Flange (OEM 1210827), Top Carrier Rollers (OEM 6Y3908), Front and Rear Idlers (OEM 1901546), and Sprocket Segments (OEM 6I8078). These are commonly replaced during routine maintenance and complete undercarriage rebuilds.

The standard track specifications for the CAT D6M-XL conventional undercarriage are: Pitch 7.50", Bolt Diameter 3/4", Link Height 119mm, and Bushing Outside Diameter (O.D.) 65.0mm. These specifications apply to all serial prefixes covered by this guide: 2YS, 3WN, 4HS, 5WR, 6LR, and 9ZM.

CAT D6M-XL track shoes are available in 22" and 24" widths. The correct width depends on your machine's original configuration and your application requirements. Wider shoes provide greater flotation on soft ground, while narrower shoes offer better traction on firm terrain. Confirm your machine's original shoe width before ordering.

When replacing your CAT D6M-XL track chains, inspect the track shoes, sprocket segments, lower rollers, carrier rollers, and front and rear idlers. Replacing worn mating components at the same time helps maximize the lifespan of your new track chains and prevents premature wear on the new components.

The Caterpillar D6M-XL uses two lower roller design variants. The Former Design features integrated end collars (OEM 1210824 for Single Flange, 1210827 for Double Flange). The Latest Design uses separate end caps (OEM 3104912 for Single Flange, 3104915 for Double Flange). It is important to match the replacement roller to the design variant already installed on your machine, as the mounting configurations differ.

A complete CAT D6M-XL undercarriage rebuild typically requires 2 track chains, track shoes (22" or 24" width, 2 sets), lower rollers (quantity varies by position — single flange and double flange), top carrier rollers (2 per side), front and rear idlers (2 per side), and sprocket segments (14 per side). Additional hardware such as track bolts and nuts may also be required depending on wear.

No. While the D6M, D6M-XL, and D6N are related Caterpillar dozer models, their undercarriage specifications differ. The D6M-XL uses a 7.50" pitch track with 119mm link height and 65.0mm bushing O.D. Always confirm the exact model and serial number prefix when ordering replacement undercarriage parts to ensure correct fitment.
