Michigan 55 III Parts Catalog – Factory OEM Parts Manual

You’ve got a Michigan 55 III tractor shovel that needs parts. You pull the old part, measure it, guess a number, order it, and it’s wrong. That’s wasted time and money. Michigan 55 III Parts Catalog — 122 pages, OEM factory print — is the reference that stops that cycle. Every gasket, every hydraulic line, every clutch group has a factory part number. No aftermarket approximations. You need the right part the first time, or the machine sits.

Michigan 55 III Parts Catalog: Engine Accessories and Air Cleaner Assembly

Starting up front: the engine accessories section (page 1) covers the fuel tank cap, radiator cap, oil reservoir cap, and the entire air cleaner system. The manual breaks down the air cleaner connections (page 12) and the element assembly (page 13) with separate part numbers. If you’re replacing an air cleaner element on a GM or DAF TS-6792-P engine, you get the exact OEM filter part — not a generic substitute. The accelerator pedal linkage and rods are on page 17. Each rod, each clevis pin, each spring — listed with a part number. No hunting through aftermarket catalogs.

Brake Valve: What Parts Are Listed on Page 50?

Page 50 is where the air brake valve lives. The manual lists the valve assembly, the brake pedals, and the associated controls. You also get the air brake pedals and the parking brake lever assembly (page 47). The reservoir, air lines, and pressure sender unit are on page 53. If you’ve ever had an air brake valve leak because someone reused a seal from a generic kit, you know why OEM part numbers matter. This catalog gives you the factory seal part. No guessing.

Transmission Clutch Groups — Forward, Reverse, Low

The transmission case (page 21) and the clutch groups are laid out in separate exploded views. The manual shows the clutch group – forward, reverse, and low – along with the high clutch group (page 23). The transmission air breather is page 21. The cartridge kit for the transmission and converter filter is page 27. You need to rebuild a transmission? You order the exact clutch plates, seals, and bearings from the numbers in this catalog. The torque converter charging pump is on page 29. That pump’s part number is not interchangeable with anything else. Factory data only.

Bucket and Boom Hydraulic System: Pump and Cylinder Assemblies

Page 65 kicks off the bucket and boom hydraulic system. You get the pump assembly (page 68), the boom cylinder (page 66), and the bucket cylinder (page 67). The cutting edges and teeth data are on page 7. If you’re swapping a boom cylinder, you need the exact shaft seal kit. This catalog lists that kit by part number. The hydraulic reservoir cap and oil reservoir cap are also specified. No aftermarket cross-reference needed. Michigan Model 55 III Tractor Shovel Parts Manual gives you the full system breakdown.

7 Major Systems Covered in This Parts Catalog

Go through the index and you see seven clear groups: Engine and accessories, air cleaner, brake system, transmission and torque converter, bucket and boom hydraulics, steering, axles, and electrical. Each group has its own section with component part numbers. The front drive axle assembly is page 33; the rear drive steer axle is page 37. Wheel cylinders, brake assemblies (front and rear, pages 42–43) — all separate callouts. The electrical side covers battery compartment (page 80), battery cables (page 87), ammeter and air pressure gauge (pages 73, 75), and the cockpit wiring harness (page 87). Michigan 55 III Tractor Shovel Parts Catalog shows the same exploded views you’d see on a dealer’s parts counter.

Steering and Axle Assembly: Front Drive and Rear Steer

The steering column assembly (page 60) and steering gear filler cap (page 61) are included. The axle assemblies list every bearing, seal, and gear. If you’re replacing a front axle seal on a 55 III, you need the factory part number. This manual gives it. The brake air lines (page 53) and the parking brake controls (page 47) complete the undercarriage coverage. For context on heavy equipment design, see Automotive Industry Overview.

Does This Manual Include Torque Specifications?

Yes, torque values are listed on assembly drawings throughout the catalog. For example, the brake valve and axle nut torques appear on the exploded views. Page 50 and page 65 have callouts for critical fasteners. This is not a service manual — it’s a parts catalog — but the engineers included torque specs where it matters for correct installation. You still need a torque wrench. Automotive Industry Overview confirms that OEM documentation always includes those values. No excuses.

Why Trust This Factory Print Over Aftermarket Catalogs?

Aftermarket parts catalogs often combine multiple model years into one generic list. This manual is machine-specific: the Michigan 55 III, serial number range printed on the cover. The original Clark Equipment prints were used in dealership parts departments. The 122 pages are not reprints of reprints — they are scanned from the factory binder. Volvo BM Michigan 125C 1988 Parts Catalog – Factory OEM Parts Manual shows the same level of detail for a related model. If you order parts from this catalog, you get the part that fits. Period.

How do I find the correct part number for my specific 55 III serial number?

Use the machine serial number printed on the data plate. The manual’s index points to the section (e.g., page 7 for bucket data, page 21 for transmission case). Cross-reference the serial number with any revision notes in the manual — sometimes later 55 III models used updated parts. The catalog lists the part number and the superseded numbers if applicable. If you have a pre-1970 machine, check the engine section (page 1) for differences in the accelerator rod linkage. The manual covers both GM and DAF engine variants. Order by the part number, not by description alone.

Does this catalog include wiring diagrams?

Yes, but limited to part identification. The wiring harness pages (87) show the harness assembly with connector part numbers. For full routing, you need the service manual.

You have the machine. You need the parts. Don’t trust an aftermarket list that might be wrong. Access the Factory Manual from AutoRepairManuals and get the exact part numbers that Clark intended. 122 pages, OEM print, torque specs where they matter. Your Michigan 55 III will run again without the guesswork.
