Michigan 55 AWS, 55 R Parts Catalog – Factory OEM Parts Manual

If you’ve ever had a machine down because the part number you ordered didn’t match the brake valve assembly, you know the frustration. That’s why I reach for the Michigan 55 AWS, 55 R Parts Catalog before I write up a parts request. This isn’t a reprint or a generic aftermarket list — it’s the original Clark Equipment factory parts manual, 234 pages thick, covering both the 55 AWS and 55 R models with DAF and Perkins engines. Page 1 tells you to record your machine serial number. That’s the first step you don’t skip.

Transmission & Torque: How the Index Breaks It Down

The index on page 3 groups Transmission & Torque under a single heading. That’s smart because the torque converter and transmission share oil circuits and pressure specs. You’ll find the torque converter assembly on page 24, the transmission assembly and mountings on page 26, and the pressure regulating valve on page 25. If you’re rebuilding the converter, you need the factory part numbers for the stator, turbine, and seals — not some aftermarket cross-reference that may or may not fit. This catalog gives you the original Clark part number, period.

Brake Assembly, Valve, and Wheel Cylinder: Three Separate Sections

The brake system gets its own real estate. Brake assembly appears on pages 49, 50, and 55. Brake valve assembly is page 64. Brake wheel cylinder lives on pages 51 and 52. Why does that matter? Because parts are not interchangeable between the AWS and R models without checking the serial number range. The catalog tells you which page has the correct part for your machine. Don’t guess — flip to the right page.

Cylinder Assemblies: Boom, Bucket, and Steering

Three cylinder sections: boom cylinder assembly on page 60, bucket cylinder assembly on page 61, steering cylinder assembly on page 62. Each page has an exploded view with callouts. If you need a seal kit or a new rod, you can read the part number right off the drawing. Aftermarket catalogs often combine all cylinders into one list and you end up with the wrong bore size. Not here.

Wiring and Electrical Equipment: Battery, Carrier, and Lights

Electrical equipment starts on page 23 with battery, carrier, and wiring. Lights and mountings are also on page 23. The instrument panel is page 22. If you’re chasing a ground fault or replacing a harness, you need the correct wire gauge and connector part numbers. This catalog has them. No need to trace wires with a multimeter for hours — look up the wiring section and order the right harness.

Does This Manual Cover Your Engine?

Yes, it covers DAF and Perkins engines used in the 55 AWS and 55 R models. Engine & mountings are on page 13, engine controls on pages 14 and 15, fuel system on pages 19 and 20, fuel pre-filter on page 21, radiator connections on page 16, radiator and mountings on page 17. If you’re ordering a fuel injection pump or a water pump, the part number is in this catalog. Don’t rely on aftermarket cross-reference databases that mix up metric and SAE threads.

One more thing: the hydraulic pump sections. Front end hydraulic pump is page 38, steering pump is page 41. Both are critical for steering and lift functions. Pair those with the hydraulic lines for steering on pages 39 and 40, and you can rebuild the entire hydraulic system from part numbers alone.

For the larger machines, Volvo BM Michigan 125C 1988 Parts Catalog – Factory OEM Parts Manual and Michigan 851 Parts Catalog – 72-Page Factory Parts Manual might be useful. For a broader context on heavy equipment parts sourcing, see Automotive Industry Overview. And Automotive Industry Overview also provides background on manufacturing standards.

Does this manual include torque specifications?

Yes. The index lists “Torque” under the Transmission & Torque heading. You’ll find factory torque values referenced for the pressure regulating valve (page 25), torque converter assembly (page 24), and transmission mountings (page 26). These are the original Clark specs — not rounded-off aftermarket numbers. If you’re tightening a valve body bolt or a converter housing nut, use the values from this manual to avoid leaks or cracked castings. Skipping torque specs on a machine this size invites failure.

Can I rebuild the transmission using this manual?

No. It is a parts catalog, not a service manual.
