Caterpillar 14H 2002 Parts Catalog – Factory OEM Specs

If you’ve ever ordered a part for a Caterpillar 14H 2002 Parts Catalog based on a guess or a generic parts website, you already know the pain. Wrong gasket. Wrong piston ring. Wrong seal. Then you wait three days for the right one, the machine sits, and the job goes sideways. That’s why this manual exists. It’s the actual factory Caterpillar document from February 2002, built for the 14H Motor Grader with serial prefixes ASE1-Up (machine), 3PD1-Up (engine), and BSS1-Up (transmission). 1002 pages of nothing but official part numbers, exploded diagrams, and assembly callouts. No aftermarket interpretation. No third-party editing. Just the print that came off the line at Caterpillar.

You want to know what’s inside? The Basic Engine section alone covers Camshaft, Crankshaft, Cylinder block, cylinder head, flywheel, piston and rod group – every nut, bolt, and seal. The TOC lists exact group names like CAMSHAFT GP, CRANKSHAFT GP, CYLINDER BLOCK AS, and FASTENER GP-CYLINDER HEAD. If you need a rocker arm, a valve lifter, or the front gear housing, the part number is in there. No flipping through third-party catalogs that renumber everything.

Caterpillar 14H 2002 Parts Catalog: What You Get

This is a parts catalog, not a service manual. That means every page is an exploded view with a numerical parts list. You get the exact Caterpillar part number for every component in the 14H. Need the oil pump for the lubrication system? Look under PUMP GP-ENGINE OIL. Electrical gremlins? The WIRING GP-ENGINE and SENSOR GP-POSITION sections give you the harness part numbers and sensor callouts. The manual also includes MACHINE ARRANGEMENT and CONVERSION AR-CERTIFICATION for special configurations like snow plow attachments.

Engine Arrangement and Basic Engine Sections

The Engine section starts with ENGINE AR then dives into the Basic Engine with 30 groups. That includes BELT TENSIONER GP, VALVE MECHANISM GP, and SEAL GP-CRANKSHAFT. When you’re rebuilding the top end, you need the camshaft group – it’s right there under CAMSHAFT GP. The Cylinder head assembly is broken down into CYLINDER HEAD AS and FASTENER GP-CYLINDER HEAD, so you can order the head bolts and gasket separately. No guesswork on thread pitch or length.

Using the Parts Catalog for a Camshaft or Crankshaft Replacement

Say you’re pulling the Crankshaft out of a 3176C engine (the one in this 14H). You need the main bearing set, the thrust washers, and the rear seal. This catalog lists them under CRANKSHAFT GP and SEAL GP-CRANKSHAFT. The group numbers match the factory parts system. You can walk into any Caterpillar dealer, read the part number off the page, and walk out with the right box. No return counter. No “sorry, that’s for the C15.”

Lubrication, Cooling, and Electrical Coverage

The LUBRICATION SYSTEM section covers oil filter base, oil cooler lines, oil pump, and dipstick. The ELECTRICAL AND STARTING SYSTEM section runs 30+ groups: alternator, starting motor, batteries, circuit breakers, sensors, wiring harnesses, and the ET control unit. If you’re chasing a ground fault in the cab lighting, the SWITCH GP-LIGHT and WIRING GP-CAB pages give you the connector part numbers. Factory-only data.

Source Authenticity: OEM vs Aftermarket

I’ve seen aftermarket parts catalogs that claim to cover the 14H but swap group numbers or omit the SNOW AR-MOTOR GRADER arrangement. This PDF is the genuine Caterpillar document (SEBP3328, February 2002). The original file name is Caterpillar_14H_2002_Parts_Catalog_en-18914001241.pdf – it came straight from the factory database. The index appears in five languages: English, French, Spanish, Portuguese, and German. That’s the real thing.

3 Reasons to Order OEM Documentation

1. Part numbers are verified against the actual Caterpillar production system. A cross-reference from a generic site may lead you to a superseded number that doesn’t fit.
2. Exploded diagrams show exact assembly order and fastener locations. You can see how the Cylinder head gasket routes or where the oil return line clips onto the turbocharger.
3. No missing pages. The 1002-page count includes all machine, engine, transmission, and attachment variations. Aftermarket books often drop the snow plow or the secondary steering wiring.

FAQ – Four Questions About This Parts Catalog

Does this manual include part numbers for the fuel injection pump?

Yes. The FUEL SYSTEM section lists PUMP GP-FUEL INJECTION and INJECTOR GP-FUEL with all individual components.

Can I order parts directly from this PDF?

Yes. Take the part number shown in the diagram to your local Caterpillar dealer or order online. The numbers are factory current as of 2002; some may be superseded, but the catalog lists the original group numbers.

What engines are covered in this manual?

The 14H Motor Grader uses the 3176C engine. The catalog covers that engine’s parts entirely: cylinder block, camshaft, crankshaft, piston and rod, valve mechanism, oil pump, and all gaskets and seals.

Is this the same manual that Caterpillar dealers use?

Yes. This is the exact PDF that Caterpillar published for dealer parts departments. The format matches the SIS system used at the time. It’s the same page numbers, same layout, same callouts.

Look. If you’re wrenching on a Caterpillar 14H and you don’t have the factory parts catalog, you’re flying blind. One wrong part order costs more than this PDF. The index is cross-referenced in five languages, the diagrams are crisp, and the group numbers are what every dealer computer expects.
