Caterpillar D6R LGP Parts Catalog – OEM Factory Specs

I’ve pulled enough parts off a D6R LGP to tell you right now: if you order a track roller from a third-party catalog, you’re gambling with downtime. Aftermarket part-number lists get crossed up, superseded, or flat-out wrong. That’s why you need the Caterpillar D6R LGP Parts Catalog – the 7th Edition Undercarriage Parts Sales Kit that Cat dealers used. It’s 1056 pages of factory part numbers, no guesswork. If you’re rebuilding an undercarriage or sourcing final drive components, this is the document that keeps your job on track.

1056 Pages of Factory Part Numbers

This Parts Catalog isn’t a repair manual – it’s a parts identification bible. Every page carries OEM part numbers for the D6R LGP undercarriage system. You get the full Table of Contents starting with Elevated Sprocket Tractors on page 5, then Skidders, Low Sprocket Tractors, Track-Type Loaders, Classic, Nexus, Excavators/Front Shovels, Timberking, Mini Hydraulic Excavators, Multi-Terrain Loaders, Compact Track Loaders, Paving Products, Product Information, a Conversion Guide starting on page 993, and a Part Number Index on page 1006. Need a specific bushing or sprocket segment? The index points you right to the page.

Undercarriage: What the Catalog Exposes

Track chains, rollers, idlers, sprockets, final drive seals – this catalog breaks down every wear item for the D6R LGP. The introduction (page 5) states flatly that this book is a quick reference for dealer salespeople, not a substitute for the formal Parts Book. That means you get the high-volume, competitive, and new parts listed with application data. But the catalog gives you the factory part numbers you need to order correctly. It also includes Product Information sections with features and benefits for service commodities – useful when you’re deciding between standard and heavy-duty components.

Does This Catalog Include the Final Drive Parts?

Yes, but only through the Elevated Sprocket Tractors section. The D6R LGP is an elevated sprocket tractor, and the catalog lists final drive reduction gears, seals, and bearings under that section. However, if you need engine or transmission internals, this isn’t the right book – you want the Caterpillar C15 2006 Parts Catalog – Factory OEM 884 Pages for powertrain parts. Keep that on the shelf next to this one.

Source Validity: OEM vs Aftermarket

I’ve seen aftermarket “parts lists” that swap a D6R track roller number for a D6H number and call it close enough. That’s how you end up with a roller that doesn’t fit. This catalog is the 7th Edition from Caterpillar, printed with their part numbers, their supersession notes, and their application charts. The Automotive Industry Overview shows how critical OEM documentation is for heavy equipment – and this is the real thing. No reprints, no scanned third-party copy. You get the factory PDF.

Cross-Reference Part Numbers Correctly

Don’t just grab the first number you see. The conversion guide (page 993) lets you translate old part numbers to current ones. Use it. I’ve watched guys skip that step and order a discontinued roller, then wait two weeks for a return. The catalog also includes a Part Number Index starting page 1006 – alphabetical numerical list. That’s your quick lookup.

FAQ

Is this an OEM Caterpillar manual?

Yes, it’s the factory Parts Catalog, 7th Edition.

Can I use this to order replacement parts for my D6R LGP?

Absolutely. But read the introduction on page 5 – Cat says this book is a quick reference for dealer salespeople and should not replace the formal Parts Book for final order verification. What that means for you: the part numbers are correct, but always double-check with your dealer’s Numerical Parts Record before cutting a purchase order. The catalog covers high-volume undercarriage items, not every nut and bolt on the machine.

Does it cover engine or transmission parts?

No. This catalog focuses on undercarriage components for the D6R LGP – tracks, rollers, sprockets, idlers, final drives. For engine or transmission parts, you need the separate C15 or powertrain manual.

What format is the manual?

PDF, 1056 pages, searchable.

Every time I open this catalog on the shop tablet, I save an hour of calling parts houses with serial numbers. If you’re rebuilding an undercarriage or stocking spares for a fleet, having the factory numbers on hand cuts the bullshit. The Automotive Industry Overview confirms that OEM documentation is the standard – and this is it. Access the Factory Manual and get the right part the first time.
