Michigan 475 IIIA Parts Catalog

If you’ve ever ordered a part for a Michigan 475 IIIA by eyeballing it and ended up with a brake shoe that doesn’t fit, you know the pain. This Parts Catalog is the factory-issued document that tells you exactly what part number goes where. No aftermarket guessing, no cross-referencing from a blurry photocopy. This is what Clark Equipment sent to dealers. 172 pages of exploded diagrams, assembly data, and part numbers for every system on the 475 IIIA articulated tractor shovel. I’ve torqued my share of head bolts on these machines, and the one thing that will kill a rebuild faster than a stripped thread is ordering the wrong parts. This manual kills that problem dead.

172 Pages of Factory Part Numbers

Page after page of this catalog breaks down the Engine accessories, Transmission clutches, Brake assemblies, Valve groups, and Torque converter components. The Table of Contents alone runs from “Accelerator Pedal and Linkage” (page 17) to “Boom Cylinder Assembly” (page 97). Every section lists the exact part number, quantity needed, and often a note about supersessions. Need the air brake valve? It’s on page 74. The transmission control cover? Page 35. You don’t waste a Saturday waiting for the wrong seal.

What Systems Does This Parts Catalog Cover?

The index is a mile long. Let me hit the high points: front and rear drive axles (pages 55–63), differential carriers (pages 59, 65, 71), torque converter and charging pump (pages 45–47), all six clutches (first, second, third, fourth, reverse, input – pages 31–33), steering cylinder (page 86), bucket and boom hydraulics (pages 91–97), and the entire brake air system from foot valve (page 74) to slack adjusters (pages 57, 63, 69). If it bolts onto a 475 IIIA, there’s a page for it.

Torque Specs? No – This Is a Parts Catalog, Not a Service Manual

Let me be straight with you: this manual does not contain torque values or step-by-step repair instructions. It’s a parts catalog. If you want to know how many foot-pounds to tighten the converter housing bolts, you need the service manual. But if you need to know the part number for the converter pressure regulating valve (page 48) or the cartridge kit for the transmission filter (page 41), this is your only source. Mixing up a first-clutch pack part for a second-clutch pack part will cost you a day of teardown. This catalog prevents that.

3 Reasons to Use OEM Documentation for Your 475 IIIA

First, the part numbers are verified against Clark’s own system. Aftermarket catalogs often list superseded or replaced numbers, and you end up with a part that doesn’t fit. Second, the exploded views show how every bolt, washer, and seal fits together. You see the stack-up before you order. Third, the manual covers machine serial number 421E101 and after – the specific build that matches your machine. No generic “fits all years” nonsense.

Get the Right Parts, Avoid the Headache

I’ve seen shop foremen waste two hours cross-referencing a brake air chamber from three different sources because they didn’t have the factory catalog. That’s billable time down the drain. With this Michigan 475 IIIA Parts Catalog on your bench, you pull the page, read the part number, and call the distributor. Done. If you’re rebuilding the transmission, grab the VOLVO BM 125C Wheel Loader Parts Catalog if you need a similar manual for a different machine.

FAQ – Michigan 475 IIIA Parts Catalog

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual.

Can I use this to rebuild the transmission?

You can use it to identify every part inside the transmission – from the clutches (pages 31–33) to the converter charging pump (pages 45–47) – but you will still need a separate service manual for disassembly procedures, clearances, and torque values. That said, having the correct part numbers before you start is half the battle. I’ve seen guys pull a transmission apart, find a worn clutch hub, and then spend two days trying to figure out which one of the six clutch groups it belongs to. This catalog labels each clutch group (first, second, third, fourth, reverse, input) with its own set of parts. You save that hunting time.

What serial numbers does this cover?

Machine serial numbers 421E101 and after, as printed on page 1 of the manual. Always check your serial plate before ordering.

Is this a reprint or a scan?

It is a high-resolution scan of the original OEM print. Every page is legible, including the fold-out diagrams. No aftermarket reprints, no redrawn art – just the factory document.

Access the Factory Manual and put the right parts on the first try. Your machine will thank you, and so will your wallet.
