Michigan 475 III A Parts Catalog

I’ve torqued head bolts since before some of you were born. If you’re ordering parts for a Michigan 475 III A articulated tractor shovel, you want the factory Parts Catalog. Not a copy of a copy. This is the real deal: 242 pages of indexed part numbers and exploded diagrams. Over the years I’ve seen aftermarket parts lists miss a $0.50 o-ring and cost a shop four hours of downtime. This catalog came straight from Clark Equipment Company – Construction Machinery Division. You get the same page the dealer uses.

Every machine serial number range is covered: 1AYC101 thru 1AYC999, 2AYC101 thru 2AYC999, 3AYC101 and After. Supplements at the back handle later serial prefixes. No guesswork about which revision applies.

Michigan 475 III A Parts Catalog: 242 Pages of Factory Data

Page 1 lays out the machine identification. Page 2 shows the overall view of the 475 III A with callouts for bucket, boom, lights, air cleaner, front axle, rear axle, hood, fuel tank. The index starts on page 3 and runs through every subsystem. You find things like Accelerator Pedal and linkage (page 25), Accumulator (pages 47, 49), and Brake Air lines (pages 103 through 119). Each entry gives you the exact page numbers where the part illustrations and part numbers live. That’s the difference between an OEM index and a generic scan – the factory got the page calls right the first time.

Brake Air Lines and Valves

The brake system on this machine isn’t something you want to piece together with mismatched fittings. The catalog covers Brake Air lines and Air Reservoir Mounting on pages 103, 105, 107, then continues through 109, 111, 113, 115, 117, 119. You get separate entries for Brake Assembly (pages 81, 83, 85, 89, 91, 93, 95), Brake Foot Valve and Controls (page 100), Brake Parking Valve (pages 109, 113, 117), Brake Relay Valve (pages 109, 113, 117), and Brake Shoe (pages 81, 85, 91, 95). If you’re rebuilding a brake chamber, the exploded diagram shows you every spring and diaphragm. No need to lay out parts on the bench and wonder what goes where.

Engine Accessories and Fan Belt Adjustment

Engine accessories start on page 1 with the Alternator. Pages 17 and 19 cover the Air Cleaner, Indicator and Connections. Page 21 has the Adjustment Flange – Fan Belt. Page 22 shows the Radiator Cap. Page 27 gives you the Fuel Tank Cap. Page 28 takes you through By-Pass Filter Piping – Engine. All of these are common failure points on the 475 III A. Having the factory part number saves you from ordering the wrong fan belt tensioner flange.

Check the Accumulator Section Before Starting

If you’re dealing with hydraulic system problems, the Accumulator is on pages 47 and 49. Those two pages cover the gas-charged accumulator used in the brake or pilot circuits. Without the correct part number, you can end up with a nitrogen pre-charge mismatch. The catalog shows the part number and the detail of the charging valve. That kind of detail is why I keep a copy of this Parts Catalog in my toolbox, not a third-party compilation.

Why OEM Documentation Beats Aftermarket Copies

I’ve seen aftermarket parts catalogs that take a factory diagram, blur the part numbers, and slap their own stock numbers on top. Then you call for a part and get told “that number is superseded” – which it isn’t. This is a genuine Clark Equipment Company print. Part numbers like the ones for the Bucket Assembly Data (pages 12, 13) are the numbers the dealer still uses. The index even tells you when machine serial ranges require a supplement. Aftermarket reprints omit those supplements. For more background on why factory documentation matters in the Automotive Industry Overview, it’s about traceability of part revisions.

This catalog is 242 pages. Not 240. Not 245. Exactly the same as the original binder. Every page is a direct scan of the OEM manual, not a re-typed list. Automotive Industry Overview provides context on how manufacturers standardize part numbering – and this catalog follows that standard.

If you maintain a Michigan 475 III A in your fleet, you need this Parts Catalog on your tablet or in your binder. Stop relying on internet forum part numbers that might be wrong. Access the Factory Manual now and get the real Clark part numbers.
