Caterpillar 140H 2006 Parts Catalog

If you’ve ever ordered a part for a Caterpillar 140H 2006 Parts Catalog based on an aftermarket cross-reference and ended up with a cylinder block that doesn’t match your serial number, you know the frustration. This is the only source that gets it right. Over my 28 years turning wrenches I’ve watched guys waste whole shifts chasing wrong part numbers from third-party catalogs. This factory document—1576 pages of Caterpillar-verified data—is what I use when I need to be sure. Automotive Industry Overview

Engine Arrangement: What the Manual Covers

Open the manual and the first major section is ENGINE ARRANGEMENT, then BASIC ENGINE. That’s where you’ll find the CAMSHAFT GP (camshaft group), CYLINDER BLOCK AS, CYLINDER HEAD AS, and the FASTENER GP- CYLINDER HEAD. These aren’t generic illustrations; each group has the exact part number, quantity, and serial number applicability. The manual covers the 3176C engine with specific serial number breaks (3PD1-Up for engine, BJN1-Up for transmission). If you’re rebuilding the top end, you need the roder arm group and valve mechanism group listed here. No aftermarket catalog gives you that level of granularity.

Cylinder Block and Camshaft: Getting the Right Part Number

The cylinder block group alone has multiple sub-groups: CYLINDER BLOCK GP, CYLINDER HEAD GP, PISTON & ROD GP. Each lists the correct Caterpillar part number stamped on the casting. Same for the camshaft—CAMSHAFT GP includes the shaft, bearings, and thrust plate. I’ve seen mechanics order a camshaft from an online cross-reference and get a part that doesn’t fit because they ignored the serial number prefix. This manual breaks it down by machine serial (CCA1-Up). You look up your machine arrangement, find your engine serial range, and the correct part is there. That’s how you avoid sending parts back.

Why Factory OEM Documentation Matters for the 140H

Aftermarket parts catalogs often grab data from old revisions or merge different machine configurations. Caterpillar prints this Parts Manual with the exact release date—July 2006—and includes all updates up to that point. The table of contents lists REPAIR ALTERNATIVES and SUPPLEMENTAL COOLANT ADDITIVES sections, which are rarely found in third-party reprints. Every part number has been tested on real machines. If you need a water pump (PUMP GP- WATER) or a turbocharger (TURBOCHARGER GP), the catalog gives you the correct grouping. I trust factory documentation because I’ve been burned by the other kind.

Who Needs This Parts Catalog?

Anyone maintaining a 140H motor grader. That means DIY owners with a single machine, fleet shops with multiple graders, and even dealer parts counters. Real-world use case: you’re swapping out a damaged final drive (FINAL DRIVE GP). The manual lists every component—gears, bearings, seals—with part numbers. You order the right stuff the first time. Same for electrical: if you need a wiring harness for the cab (WIRING GP- CAB) or a sensor (SENSOR GP- POSITION), it’s in the ELECTRICAL AND STARTING SYSTEM section. No guesswork, no returns.

Use the Multilingual Index to Find Parts Fast

The manual includes indexes in English, French, Spanish, Portuguese, and German. Pages 1–604 make up Volume I, with parts grouped by system. Don’t scroll through 1576 pages—go to the index, find the component (e.g., “CAMSHAFT GP”), and it directs you to the correct page. The machine arrangement section also tells you which configuration (ROADING AR, SNOW AR) applies to your machine. I keep this manual open on my bench anytime I’m tearing down a 140H. Saves me from ordering the wrong cylinder head gasket.

Does this manual cover the 140H with the 3176C engine?

Yes, it lists parts for that engine with full serial number breaks.

What if I need a part number for the camshaft group?

Look under BASIC ENGINE > CAMSHAFT GP. The group includes the camshaft, bearings, bolts, and thrust plate. Match your machine serial number range (CCA1-Up) to the correct part listing. The manual also shows which earlier superseded part numbers are replaced by current ones. If you don’t have the exact serial number from your machine’s plate, you risk ordering a camshaft that won’t fit. I always verify the engine serial (3PD1-Up) before I write up a parts order. The index can get you to the right page in under a minute if you know the component name. For camshaft, the English index lists it alphabetically; the Spanish index (ÍNDICE) is also there if your crew speaks Spanish. This is the only catalog that guarantees the part number matches the original Caterpillar build sheet.

Everything in this catalog is verified against the actual machine build. Stop using aftermarket cross-references that cost you time and money. Access the Factory Manual from AutoRepairManuals and get the exact part numbers your 140H needs.
