Caterpillar 815B 1998 Parts Catalog

If you’ve ever ordered a part for a Caterpillar 815B Soil Compactor based on a third-party parts list and ended up with a seal that doesn’t fit, you know the frustration. That waste of time and money is what factory documentation eliminates. This is the genuine 1998 Caterpillar Parts Catalog for the 815B. 801 pages of OEM part numbers, exploded views, and serial number breaks. Not a reprint, not a scan of a scan – this is the original factory PDF from Caterpillar’s SIS system.

7 Systems Covered in This Parts Catalog

This catalog breaks down every major system of the 815B. It covers the machine (serial 17Z1-Up), the 3306 engine (serial 08Z3945-86459), the transmission (4MA1-585), the bulldozer (39S1-585), and two separate torque converter ranges (3DT1-Up and 81T1-Up). Each section has its own part number index and exploded diagram. The catalog is Volume II, pages 381 to 1102, but the full document runs 801 pages including the French, Spanish, and Portuguese translations found at the front.

What Serial Numbers Are Included?

Serial number breaks matter when ordering parts. The machine prefix 17Z1-Up means all 815B units built after a certain point. For the engine, you need the 08Z3945-86459 range. Transmission serials run 4MA1-585, bulldozer 39S1-585, and torque converters 3DT1-Up and 81T1-Up. If your machine falls outside these ranges, you need the earlier volume or a different catalog. That’s why factory documentation is non-negotiable – one wrong digit and you’re holding the wrong part.

Engine and Drivetrain Parts Breakdown

The 3306 engine section is the heart of this catalog. You get every gasket, piston, ring, bearing, injector, and bolt in OEM part number form. The transmission section covers both the power-shift and direct-drive variants. Torque converter parts are split into two groups based on the build date. Every part has a reference number tied to an illustration number, so you can visually confirm what you’re ordering.

Get the Right Part Numbers from Factory Specs

Aftermarket parts catalogs cross-reference part numbers – which means they occasionally get them wrong. This manual gives you the exact Caterpillar part number, the exact quantity per machine, and the exact supersession history. No guessing. When a part is obsolete, the catalog tells you what replaced it. That alone saves hours of phone calls to the dealer.

Parts Catalog Structure: Volume II Coverage

Volume II picks up where Volume I left off. It includes the final drive, steering, braking, and implement sections. Each system has its own tab index and page numbering. The front of the book contains multilingual product and dealer information forms – useful if you need to record serial numbers for your machine. For other Caterpillar models, see the Caterpillar C15 2006 Parts Catalog – Factory OEM 884 Pages or the Caterpillar Elevated Sprocket Tractors Parts Catalog – 971 Pages. Also check the Caterpillar Undercarriage Parts Catalog – 866 Pages OEM.

When ordering parts, understanding the broader Automotive Industry Overview helps, but this catalog gives you the specific Caterpillar breakdown. For general context, the Automotive Industry Overview page provides background.

Does this catalog include torque specs or service procedures?

No. This is a parts catalog, not a service manual.

What serial numbers are covered in this catalog?

Machine serial 17Z1-Up, engine serial 08Z3945-86459, transmission 4MA1-585, bulldozer 39S1-585, torque converter 3DT1-Up and 81T1-Up. If your machine falls outside these ranges, you need the earlier volume or a different catalog. This is Volume II covering pages 381-1102 of the full 801-page publication. The engine is a 3306, and the catalog includes all part numbers for that specific build range. Verify your serial numbers before ordering to avoid mismatches.
