Clark-hurth 475B 1991 Parts Catalog – Factory OEM Specs for Michigan Tractor Shovel

You are staring at a torn seal, a broken hydraulic line, and a part number that rubbed off two owners ago. You can either crawl under the machine with a caliper and a prayer, or you can grab the Clark-hurth 475B 1991 Parts Catalog and get the actual factory number in under a minute. I have been wrenching for 28 years. I have watched guys order the wrong steering cylinder three times because they guessed the serial-number break. That is a waste of time your shop cannot afford. This is the OEM document – 552 pages, printed by Clark Equipment Company in June 1991, serial-number-specific, and organized the way the line builds the machine.

Alphabetical Parts Groups: A Through Y

The manual is laid out by alphabetical groups – Axle (A), Brakes (B), Frame (F), Transmission (T), and so on through Y. Each group page has a letter prefix: A1, B1, F1, T1. Revisions show as A1-2, A1-3. That revision marking tells you Clark issued a change. Aftermarket reprints paste that info into a generic pile. Here you see the actual factory workflow. Need the steering pump group? Find it under S. Every part number links to an exploded illustration. The illustrations are not assembly guides – they are identification tools. Do not try to rebuild an axle using only the parts drawing. That is what the service manual is for. This catalog is for ordering the correct piece the first time.

What Makes This Parts Catalog Different from Aftermarket Versions?

Aftermarket parts lists are copies of copies. Sometimes they merge two revisions, sometimes they drop a footnote. This Clark-hurth 475B Parts Catalog is a direct scan of the original 1991 print. The “How to Use This Parts Manual” section on page 3 explains the serial-number suffixes – an asterisk (*) on a page title means the illustration applies only to certain serial-number breaks. The footnote tells you which. If you buy a third-party CD or a cheap access, that footnote might be missing. Then you order the wrong pinion bearing and the machine sits. I have seen it happen. The 552 pages include the warranty statement, the ordering instructions, and the full alphabetical index. No guesswork.

Use the Serial Number to Match Your Machine

Front cover tells you this catalog covers Cummins-powered machines 421J102 and up, and G.M.-powered machines 420B102 and up. Write your machine’s serial number on the cover as instructed. Then when you flip to, say, the axle group, check the footnote on the page for that serial-number range. If your unit is outside the range, you need a different section or a later revision. This is how you avoid buying an axle housing that does not fit. Pay attention to the serial-number column on every illustrated page. I have seen a shop order five brake cylinders before someone read the footnote. Do not be that guy.

Warranty Information: Know Your Coverage

Page 1 contains the original Clark warranty – six months or 1,000 hours, whichever comes first, with a one-year shelf limit. That is history now, but the language matters because aftermarket parts suppliers sometimes misrepresent OEM coverage. This catalog text is the original legal language. Use it to understand factory design intent. The manual also includes the original part-number ordering instructions: “Order by Part Number, Description and Quantity.” No shortcuts. No ambiguous cross-references.

552 Pages of Verified Part Numbers

Every page is a numbered PDF page – from page 1 through page 552. No missing pages, no dodgy scans. I have obtained manuals from other sites where pages 112–117 were ripped from a different model. This file is complete. The bookmarks allow you to jump directly to the group letter. Need the transmission? Bookmark to T. Need the bucket linkage? Check group B or L depending on the arrangement. The catalog is organized for a mechanic who does not have time to flip through 500 pages blind. Use the alphabetical index. Use the bookmarks. Get your part number and move on.

Related Manuals You Should Consider

Does this catalog include torque specs or repair instructions?

No. This is a parts identification and ordering manual. Torque values and assembly procedures are in the separate service repair manual.

Can I use this for a 475A or 475C?

No. The 475B has specific serial-number breaks. Using this for a different model will give you wrong part numbers.

How do I know if my serial number is covered?

Check the front cover. For Cummins machines: 421J102 and above. For G.M.: 420B102 and above. If your number is lower, this catalog may not cover your machine.

Why is the warranty section important if the machine is out of warranty?

Because the warranty text defines what Clark considered original equipment. Aftermarket parts suppliers sometimes claim their parts are “OEM equivalent” but the warranty language here shows original design specs. Useful for legal or insurance disputes.
