Clark-hurth 55C Parts Catalog – 238 Pages of OEM Specs

If you’re ordering parts for a Clark 55C articulated loader and relying on aftermarket cross-reference lists, you’ve already wasted time and money. I’ve seen it happen more times than I can count—wrong bearing, mislabeled seal, part number that doesn’t match the serial number. That’s why you need the factory-issued Clark-hurth 55C Parts Catalog. This is the document the distributor uses. 238 pages, OEM numbering, and the original arrangement from Clark Equipment Company. No guesswork involved.

Every page of this catalog comes straight from the engineering department. The PDF is scanned from the original MP-081-M manual, covering the Clark 55C model with machine serial number blanks on page 1 for you to fill in. Groups A through G list standard equipment; Group H handles optional and accessory items. That separation alone saves hours of cross-checking. CLARK 55C Parts Catalog is the exact same document used by Clark distributors worldwide.

Alphabetical Group Layout: Finding Any Part Fast

Sections run A through G in alphabetical order. Each group is page-numbered with a prefix letter (A1, B2, C3) and a hyphen followed by a version number (A1-1, B1-2). That version number tells you which revision covers your machine. New pages arrive from Clark with an updated first serial number—if you don’t cross-check that number, you’ll order a part that won’t fit. The page numbers sit in the upper right corner of the parts list (right-hand pages), and the machine serial number range sits in the lower right corner. Check that number before you call your distributor.

Why OEM Clark-hurth Parts Matter for Torque and Fit

Aftermarket parts catalogs often renumber components or omit supersession history. This OEM catalog keeps the original Clark part numbers and shows where each part goes via exploded illustrations. The left-hand pages carry illustration numbers like PC-A02, and when a design change happens that number gets an increment (PC-A02-1). That’s how you track revisions without guessing. Torque values? This is a parts catalog, not a repair manual, so you won’t find torque specs here. But you will find the exact bolt, washer, O-ring, and seal that matches the factory drawing. Use that to source the correct fastener so the thread engagement and clamping load stay within design limits.

3 Things This 238-Page Catalog Tells You

First, the exact part number and description for every component on the loader, down to the last cotter pin. Second, whether the item is “Not Illustrated” (marked with *) or “Not Sold Separately” (marked with §). Third, the beginning and ending serial number for each page revision. If you’re rebuilding a 55C transmission or axle group, you need to know if the page version covers your specific machine. The catalog even includes instructions on how to read the version code. Clark Michigan 35C/45C/55C Tractor Shovel Parts Manual covers additional models if you’ve got a mixed fleet.

Use the Machine Serial Number Correctly

On page 1 of the catalog, there’s a blank for you to write your machine serial number. That’s not decoration. Every subsequent page has a serial number range printed in the lower right corner. If your machine serial is higher than the range on that page, you need the next revision. The distributor tracks these revisions by noting the first serial number changed when a new page arrives. You are expected to do the same. Write it in pencil. Keep the catalog current. Otherwise you’re ordering blind.

Symbols and Notes – What Those Marks Mean

The catalog uses four symbols consistently. An asterisk (*) means the item is not illustrated—usually hardware or small parts listed separately. A section mark (§) means the part is not sold individually; you buy the assembly. A plus sign (+) sends you to the index for a cross-reference. A bullet (•) or “As Required” note means quantity depends on your build configuration. Ignoring those symbols leads to ordering parts you can’t use. Clark-hurth L320 1991 Parts Catalog – 690 Pages OEM Specs follows the same logic for a larger machine, but the symbol rules are identical.

One more thing about the index. Group H in this catalog lists all optional and accessory items. That includes attachments like cab options, lights, and hydraulic kits. If you’re working on a machine that came from the dealer with a non-standard bucket or coupler, check Group H before you start flipping through A-G. Saves time.

Does this catalog include torque specifications?

No, this is a parts catalog, not a repair manual.

How do I know which revision page is correct for my 55C?

Each page shows a machine serial number range in the lower right corner. Compare that range to your loader’s serial number. If your serial is higher than the range printed on the page, you need the next revision. The catalog tracks revisions via a page version number (e.g., A1-1, A1-2). Clark updates the version number each time a design change occurs. The distributor is supposed to note the first serial number of the new page when it arrives. As the owner, you must keep a record of your machine’s serial and only order parts from pages whose serial range includes your number. Skipping that step is the #1 cause of wrong parts in the field.

You’ve seen what happens when someone orders a transmission filter using an aftermarket number. The thread pitch is off, the gasket doesn’t seal, and you’ve got a leak before the machine even fires. Stop burning time on bad data. Access the Factory Manual and get the real Clark-hurth part numbers for your 55C. Your toolbox—and your machine—will thank you.
