Clark-hurth 55B, 55-IIIA 1993 Parts Catalog – Factory Specs for Michigan Tractor Shovels

I’ve been turning wrenches since before most of you were born, and I’ve seen more parts orders go wrong than I care to count because someone grabbed a “compatible” aftermarket cross-reference instead of opening the factory book. If you’re maintaining a Clark-hurth 55B or 55-IIIA Michigan tractor shovel, you need the actual part numbers that came off the assembly line. This 1993 Parts Catalog is the only way to be sure the seal, bearing, or hydraulic line you order will fit without grinding, bending, or cursing. At 494 pages, it covers every subsystem from the frame to the final drive.

What You Get in This 494-Page Parts Catalog

This isn’t a generic aftermarket compilation. Every page comes directly from Clark Equipment Company’s Graphic Arts Center, printed in October 1993 (10/93). The manual is indexed by serial number ranges for three engine options: Cummins 433B101 & above, G.M. 416C101 & above, and Perkins 4152C101 & above. You also get the ENC and FSC variants for each. The catalog includes exploded-view diagrams and full part number callouts for the drivetrain, hydraulic system, axles, and operator station. I’ve used factory parts catalogs like this to track down a bearing race that had been superseded three times—saved me a week of cross-referencing.

Does This Manual Cover Your Engine?

Look at the serial number on your machine’s ID plate. If it falls within the ranges listed on page 1 (Cummins 433B101 onward, G.M. 416C101 onward, Perkins 4152C101 onward), this catalog covers it. That’s three common engine families—Cummins, GM, and Perkins. The catalog doesn’t include repair procedures; it’s a parts manual. You use it alongside a service manual to identify the exact bolt, spring, or gear you need. For example, the torque converter section lists all seals and bearings with OEM numbers—no guessing what aftermarket house number crosses to the factory part.

Why Factory Parts Catalogs Beat Aftermarket Cross-Reference Sheets

Every time I see a tech order a “replacement” part from an online catalog that says “fits Clark 55B,” I cringe. Aftermarket cross-references often combine multiple design changes into one part number, and you end up with a seal that’s the wrong durometer or a hydraulic fitting with the wrong thread pitch. This factory catalog from Clark-hurth lists the exact part as it left the plant. The 55-IIIA and 55B have different final drives, different axle housings—this manual keeps them separate. I’ve had to re-order a steering column rebuild kit because the aftermarket kit included parts for a 55-IIIA that didn’t fit my 55B. Save yourself that hassle.

How to Use This Catalog for Ordering the Right Seal, Gasket, or Bearing

Flip to the section corresponding to the assembly you’re working on—say, the hydraulic pumps. Each subsystem has a group number and an exploded diagram with reference numbers. Match the reference number to the table and write down the OEM part number. Then call your Clark-hurth dealer or order online using that number. If you need to check supersessions, the last pages of the catalog (around page 450 onward) contain the numerical index of all part numbers. I always tell my apprentices: never order a part for a 55-IIIA without having this book open. It’s the difference between downtime measured in hours and downtime measured in weeks.

3 Reasons to Choose OEM Documentation

1. Serial Number Specific: This catalog is tied to specific machine serial number ranges, not a generic “fits all.” If your 55B has a Perkins engine and a different transmission, you get the right parts.
2. Supersession History: Factory catalogs include updates. This 1993 edition reflects parts changes up to that date. You can track old numbers to new ones without guesswork.
3. No Aftermarket “Equivalent” Risk: The OEM part number is the only guarantee of fitment. Cross-reference sheets often mislead—one wrong digit and your wheel seal leaks.

Frequently Asked Questions

Will this parts catalog work for both the 55B and the 55-IIIA?

Yes. The manual covers both models, but it separates them by section. You need to match your machine serial number to the correct diagrams.

Does it include torque specs or repair instructions?

No. This is a parts catalog, not a service manual. It contains part numbers, exploded views, and ordering information. For torque specs you need the corresponding service manual, which we also carry on this site. Check the related manuals below.

My machine has a GM engine, not Cummins. Does this catalog cover it?

Absolutely. The catalog includes three engine families: Cummins (433B101 & above), G.M. (416C101 & above), and Perkins (4152C101 & above). All variants—ENC, FSC—are listed.

I see the print date is 1993. Are later superseded parts covered?

The catalog includes all parts in production up to October 1993. If you need a part that was superseded after that date, you’ll need to check with your dealer or find a later revision. This book gives you the base OEM numbers to start from.

I’ve been through enough parts counter battles to know that the first question they ask is “What’s the OEM number?” If you don’t have it, you’re guessing. This catalog gives you that number. Access the Factory Manual and keep it on your shop tablet or print out the pages you need for the job. You’ll order the right part the first time, every time.
