Clark Equipment 45C Parts Catalog

I’ve seen guys order the wrong goddamn part for a 45C because they guessed at the serial number. Then the machine sits dead for a week. This catalog—Clark Equipment 45C Parts Catalog—is the factory book, 496 pages of part numbers indexed numerically. No aftermarket rebranding. You use this, you order the right seal, the right bearing, the right hydraulic line the first time. It covers serial numbers for Detroit 473B, 473C, 485A and Perkins 459B, 459C, 4240A engines. That’s not a suggestion—it’s a requirement.

I’ve torqued more head bolts than most techs have had hot meals, and I’ll tell you straight: parts identification is half the battle. This Clark Equipment factory print (Pub 3228) gives you exploded views and a numerical index that cross-references every part to its page location—A3, A5, A7, all the way through Z27. You won’t find that in a cheap aftermarket reprint.

I’ve seen too many guys order wrong parts. Don’t be that guy.

What the Clark Equipment 45C Parts Catalog Contains

Inside these 496 pages you get a full numerical index—every part number listed with its corresponding illustration page. The front matter shows serial number splits for both Detroit and Perkins engines. That matters because a minor serial number change can swap a bearing or seal. Page 2 of the catalog lists the exact serial ranges: 45 DETROIT – 473B, 473C, 485A and 45 PERKINS – 459B, 459C, 4240A. Record your machine’s serial number in the space provided before you order anything.

The index uses alphanumeric grid locations (A3, A13, T19, etc.) to point you to the correct exploded-view drawing. For example, part number 106762 appears on pages A3, A5, A7, A9, A11, A13, A15, A17—that’s a component used in multiple subassemblies. Without this catalog, you’d be scrolling through generic parts lists that may not even include your model’s revision.

496 Pages of Factory Part Data

This isn’t a condensed pocket guide. It’s a full 496-page factory publication printed in the USA by Clark Equipment. Every page comes from the original litho plates. The numerical index alone runs several pages, covering thousands of part numbers. When you look up part 126462, the index tells you it’s on A3, A5, A9. Turn to that section and you see the exact part, its relationship to other components, and the callout number. No guesswork, no cross-referencing with outdated online forums.

If you need to identify a hydraulic pump seal or a bucket tooth, this catalog gives you the part number. Pair it with the service manual for assembly torque specs and clearance data. The parts catalog is the what, the service manual is the how. You need both.

Which Serial Numbers Are Included?

Page 2 of the catalog lists the machine serial numbers covered. Note: there are two distinct engine families—Detroit and Perkins. The catalog splits the parts accordingly. If your machine falls outside those ranges (e.g., a later 45C with a different engine), you need a different revision. That’s why verifying your serial number before ordering is non-negotiable. The catalog explicitly states: “For Machine Serial Numbers 45 DETROIT – 473B / 473C / 485A and 45 PERKINS – 459B / 459C / 4240A.”

Write your serial number on the line provided inside the cover. That simple act prevents ordering a part that doesn’t fit. I’ve seen shops ignore this step and then blame the manufacturer. Don’t be that shop.

Numerical Index: How to Navigate the Catalog

The index is numbered sequentially—100169, 100171, 100172, and so on—each with a grid reference like A13, A15, A17. Some parts appear multiple times because they’re used in different assemblies. The grid references are consistent across all 496 pages. Once you learn the system, you can find any part in under a minute. This is the same system Clark used in their dealerships for decades. It’s not modern, but it works. Save the PDF on your shop tablet and keep a printed copy at the parts counter.

OEM Catalog vs Aftermarket Reprints

I’ll say it once: aftermarket parts catalogs are a gamble. They often reprint outdated editions, omit serial number splits, or relabel generic parts. This Clark Equipment catalog is the original factory publication. The last page shows “PRINTED IN U.S.A.” and the part number format matches Clark’s internal system. If you buy a third-party reprint, you might get a version that lumps the 45C with the 55C and calls it close enough. Close enough doesn’t keep a machine running.

Stick with the factory document. It costs less than one wrong part order, and it pays for itself the first time you use it.

Real-World Use Case: A DIY Owner in San Antonio

I run a six-bay shop here, and I see homeowners trying to fix their own loaders. They order a brake seal kit online, it doesn’t fit, and they lose a weekend. With this catalog, you look up the brake group, find the part number for your serial range, and order exactly what you need. You can even take the catalog to your local Clark dealer and have them pull the part. That’s the kind of confidence you want when you’re working under deadline.

If you operate other Clark loaders, check out the Clark Equipment 75B 1989 Parts Catalog – OEM Factory Manual, the Clark Equipment 310, 310III Parts Catalog – OEM Factory Manual, and the Clark Equipment 12E2E 1968 Parts Catalog – OEM Factory Manual. Each is a factory-original publication, no exceptions.

FAQ

Does this catalog include torque specs for engine bolts?

No. This is a parts catalog only.

Can I use this to rebuild the transmission?

You can use it to identify every internal part of the transmission, but it won’t tell you how to take it apart or what clearances to set. The 496 pages are a numerical index and exploded-view illustrations. For example, if you need a clutch piston seal, the catalog lists the part number and shows where it goes. But you need the service manual to know the installation orientation, torque on the retaining bolts, and the correct fluid fill procedure. Without both documents, you risk reassembling with wrong parts or incorrect specs — and that transmission will fail. Aftermarket catalogs often skip serial number splits, which is why this factory catalog is the only one to trust.
