Michigan 45A Parts Catalog

If you’re rebuilding a Michigan 45A tractor shovel and you’re tired of chasing aftermarket part numbers that don’t cross-reference right, this is the only document you should trust. I’ve been turning wrenches since the Carter administration, and I can tell you that ordering the wrong hydraulic pump or brake wheel cylinder because some third-party catalog guessed at it costs you money and time. This Parts Catalog is a direct scan of the original Clark Equipment manual – 202 pages of exploded views, part numbers, and assembly group indexes. No guesswork, no reprints from some online aggregator that ran OCR through a blender.

Brake Group and Axle Assembly Coverage

Page 1 C11 starts the brake group – you get the full front and rear brake assembly, wheel cylinders, brake valve assembly, foot brake controls, and the parking brake linkage. Need the part number for the parking brake lever assembly? That’s in section D13. The axle group covers front and rear axle assemblies, differential and carrier assemblies, and the planet carrier assembly. Page 1 B5 shows the front axle assembly with every bolt and bearing identified. If you’re doing a full axle rebuild, you need this diagram to order the correct planet spider assembly – the rear one is on page 1 C8.

Hydraulic System and Pump Group

The hydraulic group runs from page 2 B2 to 2 B13 – reservoir assembly, lines for front end equipment, bucket and boom system, steering lines, and transmission lines. Pump group starts at 2 C10 with the converter charging pump, then the bucket and boom pump, then the steering pump. Each pump has its own exploded view with the exact seal and gear part numbers. You won’t find this level of detail in any aftermarket catalog. The converter group includes the pressure regulating valve assembly on page 1 F12 – that little valve is often misordered because people don’t have the factory diagram.

Why This Parts Catalog Beats Aftermarket

Aftermarket parts catalogs for this era of Clark construction equipment are notoriously incomplete. They’ll list a generic hydraulic pump and tell you to adapt it. This Parts Catalog gives you the original Clark part number – that means you can call your dealer and get the right part the first time. The transmission group (starting page 2 E6) shows the forward, reverse, and low clutch group, the high clutch group, transmission controls, and the control valve. I’ve seen shops burn up a transmission because they used a wrong seal from a universal kit. The factory diagram for the clutch group – forward, reverse and low – is on page 2 E7. That’s the difference between a job that lasts and a comeback.

Wiring Group and Electrical Equipment

Page 2 G5 starts the wiring group – batteries and battery carrier, cab light kit, nameplates and decals, and then the electrical equipment list. The wiring diagram itself is on page 3 A5. If you’re chasing a short or replacing a harness, the exploded view of the electrical equipment on page 2 G12 shows every connector, switch, and relay. And don’t skip the tool kit listing on page 3 A8 – the factory even specified the tool kit contents. That’s the kind of detail you get from Clark Equipment’s original documentation. For reference, check the Automotive Industry Overview on how OEM manuals maintain consistency over decades.

Transmission and Converter Group Breakdown

Page 2 E6 is the transmission assembly – you’ll find the clutch groups, controls, and mounting parts. The converter group starts at page 1 F6 with the converter assembly and mounting. Page 1 F12 covers the pressure regulating valve assembly – that’s a common failure point. If you’re restoring a 45A, you also need the propeller shafts section (2 C6) and the wheel and tire data (2 G2). The wheel and tire data gives you the exact rim and tire specifications – something you can’t get from a generic parts lookup.

FAQ

Does this Parts Catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views, but does not contain torque values or repair procedures. You’ll need the corresponding service manual for assembly specs.

How are the part numbers arranged?

Each group has a page reference (e.g., 1 C11 for brake system). The diagrams show each component with a callout number that cross-references to the part number in the table. The index at the front (page 3) lists every group alphabetically.

Is this a genuine OEM reprint or a copy?

It’s a direct digital scan of the original Clark Equipment manual – OEM material, not a third-party interpretation. The file is 202 pages of the original printed document, complete with fold-out pages and handwritten notes if any existed.

Will this manual work with a later-model 45A that has been modified?

This manual covers the factory configuration as built by Clark. If your machine has been modified (e.g., aftermarket hydraulic pump or different transmission), use this catalog to identify the original parts, then compare with what’s installed. For unmodified machines, every part number will match the factory build.

Don’t waste time with aftermarket catalogs that leave you wondering if the part will fit. Get the exact factory part numbers from the original documentation. Access the Factory Manual for your Michigan 45A and keep it on your tablet or printed at the bench. You’ll order the right parts and avoid the headache of returns and downtime.
