Caterpillar Elevated Sprocket Tractors, Low Sprocket Tractors, Track-Type Loaders, Skidders/Timberking, Excavators/Front Shovels Parts Catalog

If you’re ordering undercarriage parts for a D8T or a 963C and you don’t have the right part number, you’re wasting time and money. That’s where this Caterpillar Elevated Sprocket Tractors, Low Sprocket Tractors, Track-Type Loaders, Skidders/Timberking, Excavators/Front Shovels Parts Catalog comes in. 971 pages of factory data. No aftermarket guesswork. I’ve seen guys order a carrier roller for a D6R only to get one that’s off by half an inch because the parts counter used a generic cross-reference. That doesn’t happen when you have the actual OEM publication in front of you. This is the 5th Edition Undercarriage Parts Sales Kit from Caterpillar.

Call me old-school, but I trust a factory file over any third-party compilation. The book lists part numbers for link assemblies, track pins, bushings, seals, sprockets, shoes, rollers, idlers, and guards. It also covers proper track sag specs—something that’s often ignored until the machine starts throwing chains. If you’ve ever had to explain to a shop foreman why a track job failed after 200 hours, you’ll appreciate having the exact specs.

971 Pages of Factory Undercarriage Data

That’s not a typo. This PDF runs 971 pages, and every page is indexed by model and part number. The table of contents alone covers 16 major groups: Elevated Sprocket Tractors, Skidders/Timberking, Low Sprocket Tractors, Track-Type Loaders, Excavators/Front Shovels, Mini Hydraulic Excavators, Multi-Terrain Loaders, Classic, Nexus, Paving Products, Mobile Track, Product Information, Conversion Guide, and a Part Number Index. The index starts on page 924—if you need to find a specific number fast, that’s where you go. No flipping through 200 pages of thumbnails.

Which Models Are Covered in This Parts Catalog?

Everything from the D3 through the D11, plus the 500-series skidders and the entire TK line. For example, under Elevated Sprocket Tractors you get D5N, D5M, D4H, all the 561s, D6N, D6M, D5H, D6R, D6H, D7R, D7H, 572R, D8T, D8R, D8N, 587T, 587R, 583T, 583R, 578, D8L, D9L, 589, D9T, D9R, D9N, D10T, D10R, D10N, D10, D11R, D11N.

Skidders/Timberking and Low Sprocket Tractors: What You Get

If you maintain a fleet of 527 skidders or an older D6C, this catalog has the undercarriage breakdown. The Skidders/Timberking section starts on page 197, and Low Sprocket Tractors on page 251. Each model gets its own parts breakout with OEM numbers. Don’t expect service procedures—this is a parts catalog, not a repair manual. But if you need to order a set of track links for a D5H skidder, you’ll find the exact group number.

Verify Part Numbers Before You Order

I can’t tell you how many times I’ve seen a job go sideways because someone ordered a “close enough” sprocket. The Product Information section (page 885) gives you the breakdown on LINK ASSEMBLIES, TRACK LINKS, TRACK PINS, TRACK BUSHINGS, TRACK SEALS, SPROCKETS, TRACK SHOES, TRACK HARDWARE, TRACK ROLLERS, CARRIER ROLLERS, IDLERS, and GUARDS. There’s also a Conversion Guide starting on page 911 that covers determining competitive undercarriage conversions for link assemblies, track shoes, sprockets, rollers, carrier rollers, and idlers. That’s gold when you’re swapping aftermarket components and need to know the OEM cross.

Some online sources claim to have undercarriage part numbers, but they’re about as reliable as a Mass Air Flow Sensor (MAF) reading on a clogged filter. Trust the factory file. If you work on older models, the Caterpillar Undercarriage Parts Sales Kit, 3rd Edition might cover some gaps, but this 5th edition is the one to have. For engine parts, check out the Caterpillar C15 2006 Parts Catalog – Factory OEM 884 Pages. And for other machines, the CATERPILLAR TA22-M4WD Parts Manual July 2006 is worth a look.

Product Information Section: Link Assemblies, Sprockets, and Rollers

This section is where the catalog earns its keep. It breaks down each undercarriage component with dimensions, cross-references, and application notes. Need a track roller for a D10T? The Product Information pages list the part numbers by series and size. The same goes for idlers, carrier rollers, and sprockets. The conversion guide helps when you’re dealing with a machine that’s been retrofitted with a different undercarriage system. And the Part Number Index on page 924 lets you search by number instead of model—handy when you’ve got a bolt bin full of unlabeled hardware.

One more thing: this catalog is a reference for sales and parts ordering. It’s not meant to replace the official Numerical Parts Record, but it’s faster for daily use. Caterpillar themselves state that in the introduction, and I respect that. I’ve used it to verify parts for a D8R track adjuster rebuild and for a 953C loader final drive seal job. Every number checked out.

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog only—no torque values, no step-by-step rebuilds. Pair it with the service manual for repair work.

How do I find the correct track shoe part number for my D6R?

Go to the Elevated Sprocket Tractors section starting on page 3. Find the D6R sub-section. Under the track shoe entry, the catalog lists the OEM part number, width, and hole configuration. Cross-check with the Product Information section (page 885) for bolt torque patterns and hardware. If you’re converting from a different shoe type, use the Conversion Guide (page 911) to match dimensions. I’ve used this exact method to order shoes for a D6R that had been swapped to aftermarket pads—took about 10 minutes. The Part Number Index on page 924 also lets you look up by known number if you have an old part in hand.
