Fiat-hitachi FD175 1993 Parts Catalog – 575 Pages of Factory Part Numbers

You’re elbow-deep in an FD175 engine rebuild. The old bushing is wallowed out, and you need the exact replacement. Without the right part number, you order something close—then spend two hours grinding a bushing that doesn’t fit. I’ve seen it. That’s wasted time and a risky repair. The Fiat-hitachi FD175 1993 Parts Catalog is what you need: 575 pages of OEM part numbers, exploded drawings, and factory indexing. This isn’t a reprint or a third-party compilation. It’s the original document from Fiat-hitachi, covering the FD175 crawler dozer from 1/93 onward. If you’re responsible for keeping this machine running, you want the factory catalog, not a customer’s photocopy that’s missing pages.

This catalog breaks down every assembly on the machine. The engine section alone starts with serial number 061640 and up, with a clear note about emissionized engines. Page 1 shows you the engine group and part number 99447555. Page 4 dives into the crankcase: cylinder block, screws, bushings—Vandervell brand, five different bushings with distinct part numbers. You’re not guessing. You’re matching numbers from the factory drawing. That’s how you avoid a spun bearing or a leaked oil plug.

Engine Coverage: Serial Number 061640 and Up

The catalog opens with the engine group for FD175 dozers built from January 1993, including the so-called “emisionized” engines starting at serial 061640. That’s critical—later engines have different emissions components. You get the part numbers for the complete engine (99447555), plus the crankcase, cylinder head, fuel system, and more. Each section is keyed by a code like 0.021(01) for the engine and 0.040(01) for the crankcase. If your machine falls outside that serial range, you need a different catalog. But for the 1993+ FD175, this is it.

Crankcase Assembly: Identifying Bushings and Plugs

Flip to the crankcase section and you see why OEM documentation matters. Page 4 lists fourteen plugs alone—tapered, straight, different thread pitches (M12, M42, M16, etc.). One wrong plug and you have an oil leak or a stripped hole. The catalog gives you the exact part number, quantity, and description. For example, item 3 is bushing Vandervell 98471160, used one per block. Item 4 is bushing 98471161, five per block. If you order a generic bushing, you might get the wrong I.D. or O.D. With these numbers, you call your parts supplier and get the right piece first call.

3 Reasons to Trust OEM Part Numbers Over Aftermarket

First, aftermarket part catalogs often guess on supersessions. They list a “replaces” number that might fit but changes the clearance. I’ve seen aftermarket catalogs call out the wrong bushing for the FD175 crank—then the engine seizes at startup. Second, the OEM catalog shows the exact arrangement from the factory drawing. You see how many of each part go where. No ambiguity. Third, if you ever need to warranty a repair, the dealer wants the OEM part number on the invoice. Show them a copy from this catalog, and they approve the claim. Use an aftermarket number, and you’re fighting for coverage.

Page 4 Breakdown: What Each Part Number Tells You

Take a close look at that crankcase page. The cylinder block is part 4860550, an assembly. Then you have fourteen screws (4851814) to hold the main bearing caps. The bushings are listed with the Vandervell supplier name—that’s the factory-approved vendor. Six plugs of various sizes, each with a thread specification. Item 11 is a gasket 10265460, 49x42x1.5 mm. If you’re ordering parts, you read that line: “GASKET, 49X42X1,5.” You know exactly what thickness to expect. No guesswork. That’s the value of a factory catalog.

Is This Catalog Enough for a Full Engine Overhaul?

No. This is a parts catalog, not a service manual. You get part numbers and identification—not torque specs, removal procedures, or clearances. You’ll need the factory service manual for that. But if you try to rebuild an FD175 without a parts catalog, you’re ordering blind. The catalog saves you from buying the wrong piston or misidentifying a seal. Pair it with the service manual, and you have both the “what” and the “how.”

Does the catalog include torque specifications?

No. This is a parts catalog, not a service manual. You need the factory service manual for torque values.

How do I locate the correct piston part number for my engine?

Start by confirming your engine serial number on page 1—if it’s 061640 or above, you’re in the right section. Then find the piston group in the index (usually near the engine section). The catalog will list each piston with its part number, any ring set numbers, and the quantity needed. Cross-reference the drawing to ensure you’re ordering for the correct cylinder location. If your engine is below serial 061640, you’ll need an earlier catalog. Always verify before ordering—these part numbers are specific to the 1993+ FD175 with emissionized engines. A wrong piston can ruin a bore in one start-up.

If you work on construction equipment, you know the difference between “close enough” and “factory spec.” This catalog gives you the latter. Every part number, every bushing, every plug—straight from Fiat-hitachi’s engineering department. Don’t rely on a blurred scan or a parts counter guess. Get the original document. Access the Factory Manual and keep it on your tablet or printed in the shop. It’ll pay for itself the first time you avoid a wrong part.
