Michigan 475 III A Parts Catalog

If you’ve ever had a machine down because the part number on the box didn’t match the bracket on the frame, you know exactly why this Michigan 475 III A Parts Catalog belongs on your bench. I’ve seen more than one Saturday turn into a Monday because someone ordered a brake shoe for a 475 III A using a cross-reference from a third-party site. This is the OEM Parts Catalog – Clark Equipment Company publication No. 2368-R1, covering serial numbers 1AYC101 through 4AYC999. The factory index starts on page 1 with Engine Accessories – alternator, air cleaner connections, everything that bolts to that block.

Engine Accessories and Page 1

Right there on page 1 of the index: Accessories, Engine. If you need the alternator mounting hardware or the fan belt adjustment flange, you flip to that section and you get the exploded drawings with Clark part numbers. Not a generic “fits most” diagram. This is the exact layout for the 475 III A. You’ll find the Air Cleaner, Indicator and Connections on pages 17 and 19. Don’t waste time tracing air lines by eyeball – the manual gives you the routing diagrams for the Brake Air lines across pages 103 through 119. That’s not a typo; there are that many pages dedicated to air system plumbing because the brake system on this articulated shovel is not something you want to get wrong.

Bucket Assembly Data: Pages 12-13

Bucket cutting edges, assembly data – all on two facing pages. You get the part numbers for the cutting edges, the weld-on tips, the bolt pattern. No need to measure the old ones and hope. If you’re rebuilding a bucket, you don’t order blind. The manual even lists the bucket and boom hydraulic pump sections from page 131 through 137, and then the front and rear hydraulic systems separately. That level of detail saves you from pulling the wrong pump. I’ve had techs call me asking why their replacement pump didn’t line up – because they used a parts manual that combined the 475 II and III A into one diagram. This catalog separates them.

Brake System: What the Manual Covers

Brake shoes, slack adjusters, air chambers – all indexed under the Axle Assembly sections. Front drive axle assembly starts on page 79, rear on page 91. The brake foot valve and controls are on page 100. You get the brake parking valve, relay valve, drain valve locations. If you’re doing a brake job on a 475 III A, you need the O-ring part numbers and the torque specs for the chamber mounting bolts. This manual lists every component with its Clark part number. No aftermarket manual gives you that – they skip the details that stop leaks. One more thing: the air brake valve assembly on page 100 includes the internal seal kit number. That alone can save you a phone call to the distributor.

3 Reasons to Use the Factory Parts Catalog

One: the index. It’s alphabetical and cross-referenced. You want “Accumulator”? Pages 47 and 49. “Boom Cylinder Assembly”? Pages 161-162. Two: the drawings are scaled for identification, not for art. You can see the difference between a left-hand bellcrank and a right-hand one without squinting. Three: the part numbers are Clark Engineering numbers, not re-labeled Chinese knock-off codes. When you order using these numbers through your distributor, the parts arrive right. I’ve seen too many guys try to save $20 on a seal and end up with a $4000 axle tear-down because the aftermarket part didn’t fit the spline.

Who Should Buy This Parts Catalog?

If you own or maintain a Michigan 475 III A articulated tractor shovel – whether you’re a fleet mechanic, a rental yard technician, or a private owner who does their own rebuilds – this is your wiring diagram for parts procurement. Beginners? You need this more than the professional because you don’t have the mental catalog of cross-references. Home garage enthusiasts who take on heavy equipment repairs – don’t kid yourself thinking a sketch on a napkin will get you the right bearing seal. Get the factory document.

Source Validity: OEM vs Aftermarket

This is a scan of the original Clark Equipment Company print. It’s not a re-typeset version where some office intern changed a dimension. The OCR excerpt on page 2 shows “CONSTRUCTION MACHINERY DIVISION” and warnings to use only Clark-Approved Parts. When you see “Printed in U.S.A.” on the cover, you know it’s the real deal. Aftermarket manuals sometimes combine multiple models into one diagram and you end up with a part that fits a 475 II but not a III A. This one is specific to serial number range. That matters because Clark changed the hydraulic system mid-production.

Frequently Asked Questions

Does this Parts Catalog include torque specifications?

No. This is a parts identification manual, not a service manual. It gives part numbers and assembly breakdowns. For torque values, you need the service manual for the 475 III A. But you can see the component groupings – the boom cylinder assembly on page 161 shows the seal kit part number, which you’ll need when you disassemble.

Is this the same as the service/repair manual?

No. The service manual has procedures and specs. The parts catalog is for ordering the correct components. Both are essential if you’re planning a rebuild.

What machine serial numbers are covered?

1AYC101 through 4AYC999. If your machine is outside that range, you should check with a dealer before relying on these part numbers.

How many pages?

236 pages.

Don’t waste shop time hunting for part numbers that might be wrong. Access the Factory Manual and keep it on your tablet or print the pages you need. When you order parts with the correct Clark Engineering number from the manual, the job goes together the first time.
