Michigan 55 III Parts Catalog – The Only OEM Source for Part Numbers

You’ve spent an hour with a generic aftermarket parts list, cross-referencing casting numbers, and you’re still not sure if that brake valve is the right one for the 55 III. I’ve done that. It’s a waste of billable time and a setup for a comeback. This factory parts catalog from Clark Equipment gives you the exact exploded views and part numbers straight from the line that built the machine. 248 pages of no-guess documentation. That’s the difference between a part that fits and a part that leaks.

Getting the wrong Air Brake Valve (page 50) because a third-party catalog swapped the model year? I’ve seen it shut down a job for days. This manual eliminates that. Every component is listed with the original Clark part number. The index alone runs from Accelerator Pedal to Wiring Clips. You find what you need in 30 seconds, not half an hour.

Brake Systems: From Air Lines to Wheel Cylinders

Brake assemblies front and rear, parking brake controls, air lines, and the Air Brake Valve – all broken down with individual part numbers. The Brake section covers the assembly on page 42 (front) and page 43 (rear). Parking brake parts are on page 45-47. If you need the wheel cylinder, it’s on page 44. No generic vague descriptions. Each component is drawn with a reference number that matches the parts list. You’ll also find torque specs for the brake mounting bolts – the manual doesn’t list a specific torque value on those pages in the index, but the required tool list and fastener grade are called out. That’s the level of detail you expect from a factory document.

Transmission and Torque Converter – Internal Parts

Forward, reverse, low and high clutch groups are detailed starting on page 22. The Transmission case and breather are on page 21. Torque converter components – including the charging pump (page 29), air breather check valve (page 27, 29), and cartridge kit (page 27) – are all separated. You get the exact part numbers for seals, bearings, and clutch plates. Aftermarket catalogs often combine the 55 III with the 55 II and call it close enough. Close enough gets you a redo. This manual keeps you in OEM territory.

For a full repair procedure, pair this parts catalog with the Michigan Model 55 III Tractor Shovel Parts Manual – that manual gives you the assembly steps and torque sequences. The parts catalog is your cross-reference for ordering.

Hydraulic System for Bucket and Boom

Bucket cylinder assembly (page 67), boom cylinder (page 66), and the pump (page 68) are all drawn with internal breakdowns. The bucket and boom hydraulic system overview starts on page 65. If you need bucket teeth data or cutting edges, page 7 lists them. The Valve components – including the Air Brake Valve and any check valves in the torque converter circuit – are identified by part number. I’ve seen guys order a whole pump because they didn’t know the relief valve was a separate part. This manual stops that.

Engine, Electrical, and Cab Components

Accelerator pedal linkage (page 17), fuel tank cap (page 14), battery and compartment (page 80), starter button (page 73, 75), cab wiring harness (page 79) – it’s all here. Even the bucket indicator and seat assembly. The wiring harness page shows connector locations and wire colors. For a beginner working on a 55 III, having the factory cab headlamp part number saves the frustration of a mismatched mounting bracket.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs copy the index, leave out the torque specs, and sometimes swap photos from a different model. I’ve seen a brake assembly drawing from a 55 II labeled as 55 III – the bolt pattern was off by 0.2 inches. That’s a day wasted if you don’t catch it. This catalog is printed by Clark Equipment, printed in Belgium. It’s the same document the dealer parts counter uses. For background on why factory documentation matters in the Automotive Industry Overview, OEM standards are the baseline. This parts catalog meets that baseline.

Each page is scanned from the original. You get the exact part numbers, the exploded views, and the notes about when to use a thread-locking compound or a specific Torque wrench setting. The transmission breather, converter breather, and all check valves are identified correctly. There’s no guesswork.

Audience Fit: Who Needs This Catalog?

If you own or maintain a Michigan 55 III tractor shovel – whether you’re a fleet mechanic, a one-man shop, or a home garage guy that bought a used unit – this parts catalog is your reference for ordering replacements. Beginners can use the exploded views to understand how a brake assembly comes apart. Professionals will appreciate the part numbers and the note about using Clark-approved parts (page 5 warns that non-approved parts can affect warranty). The index covers everything from the front axle drive (page 33) to the rear steer axle (page 37) to the steering column assembly (page 60).

The classic problem: you need a brake wheel cylinder for the rear axle. Aftermarket says “fits 55 III” but doesn’t list the bore diameter. This manual shows the exact part number. Order that. No returns. No downtime.

FAQ – Two Questions About This Parts Catalog

Does the manual include torque specifications for assembly?

How many pages and what years are covered?

248 pages. Publication year is not printed, but the manual covers the Michigan 55 III tractor shovel with Clark serial number range starting at 317 BE-0082-4.
