Michigan 55A Parts Catalog – Factory OEM Parts Manual

I’ve been under enough equipment to know when a parts catalog is worth the paper it’s printed on. The Michigan 55A factory catalog from Clark Equipment is that book. If you’re tired of aftermarket listings that give you a part number that doesn’t match the casting on your boom cylinder or brake master cylinder, you need the real deal. This is the Parts Catalog used by Clark dealers in Benton Harbor – not some third-party rehash with typos. 102 pages of exploded views and part numbers that match what came off the assembly line.

Parts Breakdown for the Michigan 55A

Every section in this catalog matches the original index: Accelerator Pedal and Linkage, Axle Assemblies front and rear, Boom and Guide Bar, Bucket and Carrier Assembly – it’s all there. You get the factory drawing for the Boom Cylinder Assembly and Bucket Cylinder Assembly. Need the part number for the bucket cutting edge? It’s listed. The brake lines – front – are called out with the exact fittings. This isn’t a generic diagram; it’s the same layout the Clark parts counter used.

Why a Factory Parts Catalog Beats Aftermarket

Aftermarket catalogs save you a few bucks and cost you hours. I’ve seen listings where the steering cylinder seal kit was shown with the wrong bore size. With this OEM book, you get the part number that Clark stamped into the casting. The Wiring section (Battery Cables and Wiring, Ignition Cables) shows the exact routing and connectors. You won’t be guessing which fuse fits the light switch – it’s listed under “Fuse, Light.” The Brake section covers the front brake assembly, parking brake, and the master cylinder. Every part can be cross-referenced to your machine serial number.

Wiring and Electrical Components

Electrical gremlins on a 55A shut down a job site fast. This catalog includes every electrical part: Ammeter, Back-Up Lamp, Battery and Battery Box, Battery Cables, Coil, Ignition Switch, Generator, Head Lamp, Tail Lamp, Dash Lamp, and the Instrument Panel Assembly. You get the part numbers for the sender units on the engine oil pressure and temperature gauges. Even the hourmeter pressure switch is listed. If you’re chasing a no-start condition, having the correct ignition switch and coil numbers saves you from buying the wrong parts.

Cylinder and Hydraulic System Coverage

Hydraulic leaks on a tractor shovel are expensive. This catalog breaks down every cylinder: Boom Cylinder Assembly, Bucket Cylinder Assembly, and Steering Cylinder Assembly. You also get the full hydraulic pump listings – both the bucket and boom pump and the converter charging and steering pump. The hydraulic oil reservoir, control valve assembly, and all hoses (Boom Pipe) are shown. If you need to rebuild a cylinder, the seal kit part numbers are in the catalog. No more measuring old seals and hoping.

Brake Assembly: What’s Inside

The Brake section covers the front brake assembly and parking brake assembly separately. Parts like the brake master cylinder, brake lines front, and the brake controls and floorboard are all detailed. The parking brake controls have their own listing. This catalog also includes the brake pedal linkage and the floorboard plates. If you’re replacing shoes or cylinders, you get the factory part numbers.

102 Pages of OEM Specs

With 102 pages, this isn’t a condensed pamphlet. Every page corresponds to a specific assembly – from the Torque Converter Assembly (see page 29 in the original index) to the Frame and Cradle Assembly. The back sections cover decals, hardware kits (like the Cartridge Kit for the by-pass oil filter), and the propeller shafts. You even get the correct part numbers for the fan belt and fan blade. Order with confidence that the part you receive will fit.

Frequently Asked Questions

Can I use this parts catalog for the 55A Series II?

No, this covers the original 55A only. The Series II has different axle and brake parts.

Does this include wiring diagrams?

This is a parts catalog, not a service manual, so it lists part numbers for wiring components (battery cables, ignition cables, light assemblies) but does not contain schematic-style wiring diagrams. For wire gauge and routing details, you would need the factory service manual. However, the part numbers for each connector and wire assembly are accurate and will match the original harness.

What about brake components?

The brake section covers the front brake assembly, parking brake, master cylinder, and all brake lines. Every caliper, shoe, and line fitting is listed with its Clark part number. If you need the seal kit for the master cylinder, check the “Cartridge Kit” listings – those are included under the by-pass oil filter section but the master cylinder rebuild kit is listed separately.

How do I order parts using this manual?

Locate the assembly in the index, find the exploded view on the corresponding page, and note the part number. Include your machine serial number when ordering – Clark required it to ensure correct supersession. The manual states: “Always furnish the distributor with the machine serial number when ordering parts.” Quantities are listed per assembly.
