Michigan 475B Parts Catalog – Factory Parts Manual for 475B Articulated Loader

If you are rebuilding a Michigan 475B loader or chasing down a part number that the online parts counter can’t find, you need the Michigan 475B Parts Catalog. Not a reprint from some third-party that guessed the numbers. Not a scan of a scan. This is the original Clark Equipment printed document, 350 pages of alphabetically arranged parts groups from the factory. I have torn down enough of these machines to tell you: the difference between a correct seal and a “close enough” seal is a two-day teardown to fix a leak. This catalog eliminates the guesswork. Period.

Index Model 475B – Alphabetical Parts Groups A through Z

The manual is arranged from Accelerator Pedal to Filter Elements. Each group is lettered and page-referenced. For example, the Bucket Assembly Data section includes explicit tooth adapter dimensions: 162.50 in. (4128.50 mm) for the standard bucket and 164.20 in. (4169.68 mm) for the optional bucket. You get the exact part numbers for tooth adapters, points, and cylinder assemblies. On page 73 you will find the complete Brake Air Dryer and Brake Air Lines breakdown – crucial if you are chasing air system leaks on the rear brakes. Every subassembly is exploded with callouts and part numbers. That means you can hand your parts guy a list and get the right box the first time.

Bucket Assembly and Tooth Adapter Dimensions – No Guessing

Buckets on the 475B come in two widths. The catalog lists both: 162.50 in and 164.20 in. Each has its own tooth adapter and point kit. If you order the wrong adapter, you are grinding off weld-on brackets or returning parts. The manual shows you which bucket cylinder assembly and boom bellcrank pushrod group matches your serial number. I have seen guys waste a week because they used a generic parts list from a forum. Do not be that guy. This catalog gives you the OEM numbering scheme that Clark used. Cross-reference your existing parts and order with confidence.

Brake System Coverage – Air Dryer, Controls, Drums, and Parking Brake

The brake section in this Parts Catalog covers everything from the Brake Air Dryer to the Brake Warning Light. You get the brake assembly, parking brake lever, brake drum, and all air line routing. If your 475B has air-over-hydraulic brakes, the exploded views on page 73 show the exact seal kit and valve part numbers. The Brake Controls and Parking Brake Controls are listed separately – do not assume they are the same. The factory diagrams also include the Brake Air Lines, Front and Rear. This matters because the rear line routing goes through the axle cradle and is easy to misroute. One wrong bracket and you have chafing. Use the OEM part.

Electrical System – Instrument Panels, Wiring, and Light Installations

Electrical gremlins on a 475B are a nightmare. This catalog has two full groups for the Electrical Instrument Panel – Left Hand and Right Hand – plus the Cab wiring harness. There is also a section for Electrical Lighting Installation on Roll-Over Protective Structures (ROPS). The Electrical Wiring Color Code is spelled out. If you are rewiring a cab, you need the exact connectors and terminals. The parts list includes the battery, battery box, circuit breakers, and all wire clips. The manual also covers the Engine Harness and the Engine Temperature Sender. You can cross-reference the sender part number without pulling the old one out and guessing.

Engine and Hydraulic System Filter Replacement Elements

One of the most overlooked sections is the Engine & Hydraulic System Filter Replacement Elements. This is not just oil filters – it includes the Engine Oil By-Pass Filter, Full Flow Filter, and the line kits. The hydraulic system filters for the converter charging pump and transmission are listed separately. Using the wrong filter can starve the converter and cook the seals. The catalog gives the part numbers for both the filter elements and the associated lines and gaskets. On page 120 you will find the Converter Assembly and Charging Pump breakdown. Order the correct filter head gasket and avoid the drip.

Why an OEM Factory Parts Catalog Beats Aftermarket

Aftermarket parts catalogs often group items by generic categories and leave out the serial number splits. Clark changed part numbers on the 475B during production. This catalog is organized by the original Clark index system (Groups A through Y for standard, Z for optional/accessory). The manual itself warns: “Always furnish the distributor with the machine serial number when ordering parts.” That is because the Axle Differential Carrier Assemblies, Front and Rear, have different part numbers depending on the build date. An aftermarket list will give you one part number. This factory catalog shows you both and tells you which axle assembly they fit. If you want to keep your machine working, use the document the factory used.

Frequently Asked Questions

Do I need to provide my machine serial number when ordering parts from this catalog?

Yes. The manual explicitly states: “Always furnish the distributor with the machine serial number when ordering parts.” The part numbers for axles, brakes, and electrical components changed during production. Without the serial number, you risk ordering the wrong differential carrier or wiring harness.

How many pages is this Parts Catalog?

350 pages.

Does this catalog include optional equipment like air conditioning or alcohol injector kits?

Yes. Optional and accessory items are listed under Group Z in the rear of the manual. The Table of Contents shows Air Conditioner Assembly, Alcohol Injector Kit, Counterweight Kit, and other dealer-installed options. Each optional group has its own page reference and part numbers.

Will this work for the Michigan 475B only?

It is specific to the 475B articulated tractor shovel. Do not use it for the 475A or 475C – Clark changed part numbers. The catalog covers the 475B with the serial numbers listed in the front matter (serial number range not shown, but you need to verify your machine’s serial number against the manual). Always check the serial number range before ordering parts.

The bottom line: if you work on these machines, you need the factory part numbers. Anything else is a gamble. Access the Factory Manual from AutoRepairManuals and keep it on the bench next to your torque wrench.
