Bobcat LT112, MX112, LT203, LT204, MT112 2001 Parts Catalog

If you’ve ever ordered a part for a Bobcat trencher from an aftermarket source and got the wrong tooth or chain, you know the frustration. That’s why I tell every tech: start with the factory parts catalog. This is the 2001 Bobcat Volume 6 Attachments Parts Manual, covering the Bobcat LT112, MX112, LT203, LT204, MT112 trenchers, compactors, and vibratory roller. 395 pages of exploded diagrams and genuine part numbers. Not a reprint, not a scan of a scan – original OEM print from Bobcat Company.

Volume 6 Contents: Trenchers, Compactors, and the Roller

This catalog is Volume 6 of the Bobcat attachment parts series (P/N 6901467). Inside you’ll find sections for trenchers (pages 11-302), trench compactors, and the vibratory roller. The trencher section alone covers Loader X-Change Frame, undercarriage for LT and TX models, excavator mounting frame, dowsing group, hydraulic circuitry, hydrostatic motor, trenched gearbox, chains & teeth, chain repair parts, and then model-specific breakdowns for MT112, MX112, LT112, LT203, LT204, LT213, LT303, LT304, and LT313. That’s a lot of ground.

Precision matters.

MT112 and MX112 Trencher Sections – What’s In There?

Pages 33-36 cover the MT112 trencher assembly. Pages 37-40 cover the MX112. Each includes part callouts for every bolt, spacer, and tooth holder. If you need the hydrostatic motor for LT112 or MX112, that’s on pages 41-42. The spacer kit and tooth kits for those models appear on pages 47-52. Having these pages on your workbench means you can read a part number straight off the diagram and order it right the first time.

Page 11: Loader X-Change Frame and Undercarriage

Page 11 shows the Loader X-Change Frame used to mount these trenching attachments to Bobcat loaders. The undercarriage for LT and TX trenchers is on pages 13-14. If you’ve ever fought with a misaligned mounting bracket, you know why having the factory drawing matters. The bolt pattern, the weld locations, the exact bracket dimensions – it’s all there.

Hydraulic Circuitry and Hydrostatic Motor Specs

Two pages of hydraulic circuit diagrams for the trencher (pages 21-22) and three pages for the hydrostatic motor (pages 23-25). These aren’t cartoons; they’re OEM schematics with port identifications and pressure line routing. When you’re troubleshooting a slow trencher chain, you need to check the motor. The part numbers for seals, shafts, and housings are right on those pages.

Get the Right Part Numbers With OEM Drawings

Aftermarket catalogs often use generic part numbers or skip supersessions. This Bobcat catalog includes the original part numbers as released in 2001. If Bobcat later superseded a part, you’ll need the OEM number to cross-reference. Aftermarket books also tend to leave out the small but critical items like spacer kits, seal kits, and tooth kits that are listed here for LT112 and MX112 on pages 47-52 and for LT203 on pages 69-72. Missing a spacer means a loose chain – and a broken trencher.

Real-World Use Case: Ordering a Tooth Kit for LT203

Let’s say you have an LT203 trencher and need new teeth. Open to page 71-72: Tooth Kits – LT203 Trencher. You’ll see the exact kit number, the individual tooth part numbers, and the retainer pins. No guessing. Call your Bobcat dealer or order online with confidence that the part will fit. That’s the value of a factory parts catalog: it eliminates the “maybe this fits” game.

FAQ

Does this parts catalog include service procedures or torque specs?

No. This is a parts catalog only. It contains exploded views, part numbers, and ordering information. For service procedures, you need the Bobcat service manual for your specific model.

Which models are covered in this Volume 6 catalog?

Volume 6 covers trenchers (including the LT112, MX112, LT203, LT204, MT112 and many others up to LT313), trench compactors, and vibratory roller attachments for Bobcat loaders. The full list of trencher models is found in the table of contents on page 3. If you work on any compact utility loader attachment from that era, this catalog is essential for correct part identification. Additionally, it includes detailed exploded diagrams for every subassembly, such as the dowsing group, hydraulic circuitry, hydrostatic motor, chain and tooth assemblies, and specific spacer and tooth kits for each model. Having this catalog means you can identify the exact part number without relying on guesswork or aftermarket cross-references that often mismatch.
