Michigan 55 AWS Parts Catalog – Why This Manual Belongs on Your Bench

Michigan 55 AWS Parts Catalog — 168 pages from Clark Equipment. I’ve seen guys order a brake wheel cylinder off a generic parts list and end up with something that fits a different machine entirely. That’s the difference between this manual and a cut-and-paste job. This is the factory document. It gives you exploded views, part numbers, and index cross-references for every system on the 55 AWS — from the air cleaner connections to the wheel and tires. No guesswork. You look up the index, match the serial number, and get the right part.

Michigan 55 AWS Parts Catalog: What’s Inside

Flip to the index and you’ll see sections labeled A through W. Air Cleaner Assembly, Axle Assembly, Battery Carrier & Wiring — it’s all laid out with page numbers. For instance, the Boom Cylinder Assembly is on page 49. The Brake Assembly has two listings: pages 39 and 53. Need wiring? Battery, Carrier & Wiring is on page 37. That level of detail saves you an hour of staring at a generic diagram.

7 Systems You Can Identify Parts For

Here are seven systems indexed in this manual:

• Air Cleaner Assembly (page 2)
• Brake Assembly (pages 39, 53)
• Clutch Group – Forward, Reverse & Low (page 24)
• Electrical Equipment (page 18)
• Equipment Control Valve – Transmission (page 22)
• Hydraulic System – Front End (page 25)
• Torque Converter Assembly & Transmission Mountings (page 45)

Each section has an exploded drawing with item callouts. You match the number to the table, write down the part number, and order. That’s the whole procedure.

Boom Cylinder and Brake Assembly – Examples

If you’re replacing a boom cylinder, the index puts it on page 49. The diagram shows the cylinder, seals, and mounting hardware. Part numbers are right there. For the brake assembly, you’ll find the wheel cylinder on page 4, the master cylinder controls on page 40. No flipping between sections — it’s all grouped by subsystem.

A short paragraph: That difference saves you a return trip.

Get the Serial Number Before You Order

The manual states it clearly: “Always furnish the distributor with the machine serial number when ordering parts.” That’s not a suggestion. The 55 AWS had multiple production runs. The serial number tells you which revision of a part your machine takes. Without it, you’re gambling. Write the serial number from the nameplate, then look up the part in the catalog. That’s the only way to guarantee fit.

Does This Manual Cover the Transmission and Torque Converter?

Yes. Section T includes Torque Converter Assembly, Transmission Assembly & Mountings, and Transmission Controls & Linkage — all on page 45. You get the exploded view of the torque converter, planet carrier assembly (page 13), and pressure regulating valve (page 30). For the transmission, the clutch groups are on pages 24 and 8. If you need to rebuild the transmission, you use this catalog to order the correct clutches, seals, and bearings.

Wiring and Electrical: Not Just a Diagram

Electrical Equipment is covered on page 18. But the wiring itself falls under Battery, Carrier & Wiring on page 37. That section includes the battery carrier, cables, and connectors. If you’re tracing a short, you need the part numbers for the harnesses and terminals. This catalog gives you that.

Can I use this parts catalog for a Michigan 55 R model?

No. The 55 AWS and 55 R share some components but the part numbers differ. You need the specific manual for your model.

How do I locate the correct part number for a valve assembly?

Start with the index at the front of the manual. It lists all major sections alphabetically. For example, “Valve” appears under “Pressure Regulating Valve — Torque Converter” on page 30, “Pressure Relief Valve — Steering” on page 36A, and “Selector Valve — Steering” on page 27. Each section has an exploded diagram with numbered item callouts. Match the item number to the part number table. Always verify the serial number range of your machine to ensure the correct revision. That process takes five minutes and saves you from ordering the wrong valve.
