Clark-hurth 475C Parts Catalog – Factory Parts Identification for Wheel Loader

I’ve seen it too many times: a guy tears down a Clark 475C transmission, lays out the gears and seals on a bench, then realizes he doesn’t know which clutch pack goes where because the previous owner swapped parts from three different machines. Or he orders a “transmission pump” from a parts house and gets the wrong flange because the part number was for an earlier serial number. That’s exactly why this Clark-hurth 475C Parts Catalog exists. 318 pages of factory-issued exploded views, part numbers, and application notes. You don’t guess – you identify.

Parts Identification: The Core of This Catalog

Every section in this book is built around one job: matching a physical part to a factory number. The manual covers the 475C Turbo Transmission Wheel Loader with the Cummins-483B engine. Page 1 records your machine serial number so you cross-reference later. From there, each assembly is broken down into individual components with callouts. Want to find the planetary gear set? Flip to the transmission section. Need the seal kit for the torque converter? The exploded diagram shows every O-ring, gasket, and snap ring with a Clark part number. No need to measure with a micrometer and hope – the catalog gives you the OEM number. That alone saves you a second teardown.

Why OEM Part Numbers Matter

I will not trust an aftermarket parts lookup that says “fits Clark 475C” without a serial range. Too many variations in final drives, PTO housings, and hydraulic pumps. This catalog was printed by Clark-hurth under publication number 3289. It’s the same binder the dealer parts counter used. If you work on heavy equipment, you know the difference between a genuine Clark part and a generic substitute. The factory catalog lists supersessions and interchange notes in the footnotes. On page 26, you’ll find the transmission serial number break and which shaft configurations go with which numbers. That kind of detail keeps a machine going instead of waiting for the wrong part to ship.

Page 73: What to Expect Inside One Section

Open to page 73 – that’s a typical spread in the transmission assembly section. Left side shows the complete torque converter housing with all bolts, bearings, and seals called out by part number. Right side lists the corresponding text with quantity, description, and reference notes. Common problem: the charge pump seal leaks and you think you need a seal kit. The catalog tells you the exact seal number and whether it’s part of a larger overhaul group. This isn’t a service manual with torque values, but if you pair it with the factory service book, you have the complete package. The Clark 475C Wheel Loader Parts Manual 3288 is a companion volume. For the full set, also see the Clark 475C Turbo Wheel Loader Parts Manual and the Clark Michigan Model 475C Wheel Loader Parts Manual 3246.

Audience Fit: Who Actually Needs This Catalog?

Three types of people will use this book: the shop owner who has a 475C in the bay and can’t afford to tie it up for a week while somebody calls every Clark dealer between Texas and Illinois; the owner-operator who does his own rebuilds and wants to order exactly what the engineers specified; and the parts runner who’s tired of returning crates because the computer screen said “fits all years.” Beginners – yes, you can use this too, but you need to understand that this is a parts index, not a repair manual. If you’re pulling an engine out of a 475C for the first time, you should also have the service manual. This catalog tells you what the part looks like and what number to order. That’s it – but that’s half the battle. For background on how these powertrains work, read about Internal Combustion Engine fundamentals. For industry trends, see Automotive Industry Overview.

Source Validity: Factory Print, Not a Copy

This is a scanned original Clark-hurth publication. It’s not a reprint that lost resolution, not a third-party compilation where someone typed part numbers manually and introduced typos. I’ve seen aftermarket catalogs where a “1” and an “I” got swapped, and the next guy ordered a $900 hydraulic manifold instead of a $9 fitting. The warranty page (page 3 of this PDF) spells out Clark’s original warranty terms – that alone tells you this came from the factory. When you’re ordering parts for a machine that costs six figures, you don’t roll dice on an aftermarket list. Use the real one.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It tells you what part to order and how it fits in the assembly drawing, but it doesn’t list torque values or disassembly steps. You need the corresponding service manual for that.

How do I read the exploded parts diagrams?

Each diagram has numbers that match the adjoining parts list. The number in a circle is the item number; the leader line points to the correct part. In the list, you’ll find the Clark part number, quantity used, and sometimes a note like “includes O-ring” or “serviced as set.” Start by finding the assembly you’re working on, then locate your part by the shape and position in the drawing.

Get back to wrenching. You’ve got a loader that pays your bills, and guessing parts costs you money. Open the catalog, find the number, call your dealer, and get the right piece. Access the Factory Manual and keep it within arm’s reach of the toolbox.
