Michigan 55 III 1993 Parts Catalog – Factory OEM Parts Manual

If you’ve ever tied up a machine for two days because you ordered the wrong brake wheel cylinder or guessed at a seal number, you know the cost of sloppy parts lookup. This is the Michigan 55 III 1993 Parts Catalog that Clark Equipment put out – not a reprint, not a scan of a scan. Original OEM documentation straight from the factory floor. 216 pages of exploded assemblies, indexed by model and serial number range (55 III G.M. 6BG101 and after; 55 III Wauk. 6BA101 and after). You’ll find part numbers for every fastener, hydraulic seal, and electrical component without cross-referencing three different aftermarket guides.

Engine and Accessories – Complete Breakdown

Pages 1 through 6 cover the Engine and Accessories group. You get the factory callouts for the GM or Waukesha power plant – gaskets, water pump, fuel injection lines, mounts. The index is laid out by machine serial number, so you don’t waste time flipping back and forth. Need the exact part number for the exhaust manifold gasket? It’s on page 4 under the engine group. No guesswork.

Electrical System – G M 187-1&

The Electrical section (starting page 187) includes the full wiring diagram for the cockpit and engine, plus the hourmeter, regulator, and battery cable routing. If you’re chasing a no-start or a short in the headlamp circuit, you need the factory wire color codes and connector pinouts. Aftermarket diagrams often transpose terminals – this manual shows the exact routing for the 55 III. Wiring and decals are grouped together on page 186 for quick reference.

Fuel System – Where the Manual Points You

Fuel Lines and Fuel Tank are referenced under the Frame section – not buried in a separate volume. The catalog cross-references each component back to the assembly drawing. If you need the fuel tank access door seal or the sending unit, look under “Frame and Cradle Assembly” (pages 37-39). This is how the factory intended parts to be ordered: by assembly, not by system guesswork. Saves you the headache of buying a part that looks right but doesn’t bolt up.

Hydraulic System – 7 Subsystems Detailed

This catalog breaks the hydraulics into seven distinct groups: Bucket and Boom (pages 122-131), Drott Bucket (page 132), Steering (100-105), Transmission and Converter (58-65), plus the pump and reservoir sections. Each assembly includes an exploded view with numbered callouts. The steering cylinder assembly (pages 109-110) gives you the exact seal kit number. When you’re rebuilding a boom cylinder, having the OEM part number for the piston seal means you don’t end up with a generic O-ring that blows out on the first cycle.

Index – Model 55 III: How to Navigate 216 Pages

The back of the catalog has a full alphabetical index starting with Accelerator Pedal and Linkage (pages 43-46) and ending with the Wiring Group (pages 170-192). Every major component – Axle Group, Brake Group, Converter Group, Cylinder Group, Steering Group, Transmission Group, Valve Group – has its own page range. The index is printed on the same heavy paper as the rest of the manual. No thin insert that falls out after three months in the shop.

One detail that matters: the catalog includes serial number-specific notes. For example, the brake air lines (pages 96-99) have different part numbers depending on whether your 55 III came with the GM or Waukesha engine. The factory printed separate callouts for each. Aftermarket catalogs often merge them, leading to mismatched fittings.

Does This Manual Cover the Wiring in Detail?

Yes. The Wiring Group (pages 170-192) includes the battery and battery compartment (page 170), horn and foot switch (page 159), hourmeter regulator (pages 176-177), the cockpit wiring diagram (pages 178-181), and the engine wiring diagram (pages 182-192). Also included: wiper wiring, decals, and battery cable routing. If you’re retrofitting lights or adding an auxiliary circuit, you can trace the factory harness without cutting into unknown wires.

Who Should Buy This Parts Catalog?

Anyone who owns, operates, or services a Michigan 55 III tractor shovel. Whether you’re a one-man shop in the Texas Hill Country or a fleet mechanic in the Midwest, this catalog saves you from the “it should fit” gamble. It’s also the definitive reference for ordering replacement parts from Clark or aftermarket suppliers – you hand them the OEM part number, and they don’t have to say “we need the serial number.” The 216 pages cover everything from the radiator (pages 27-29) to the Drott bucket tooth assembly (page 20) to the seat and support group (page 113).

Source Authenticity – Why OEM Beats Aftermarket

This is the original factory publication from Clark Equipment Company, dated October 12, 1993. It’s not a third-party compilation. The part numbers were verified against the production line for the 55 III – the same numbers stamped on the castings. I’ve used aftermarket catalogs that listed a tie rod end that was two threads too short. You don’t get that with the OEM book. Automotive Industry Overview and other general references can’t replace the specific cross-references you’ll find here.

FAQ – Common Questions About This Catalog

Does this parts catalog include torque specs?

No. This is a parts catalog, not a service manual. It contains part numbers, exploded views, and assembly references. You need the service manual for torque values and repair procedures.

Will this manual fit a 55 III with a Waukesha engine?

Yes. The catalog covers both GM and Waukesha engine options. The index and page callouts differentiate between the two in sections like Engine and Accessories (pages 1-6) and the wiring diagrams.

Are the part numbers still valid for ordering today?

Many are, but some may have been superseded by Clark or aftermarket suppliers. The catalog gives you the starting point. You’ll need to check with a parts dealer for current availability, but the OEM number is the gold standard for cross-referencing.

Is this a digital access or a physical book?

You are purchasing a digital PDF format of the original factory parts catalog. 216 pages, scanned from the bound original. No watermarks, no missing pages.
