Michigan 45AWS, 45R Parts Catalog – Factory OEM Parts Breakdown

If you’re trying to rebuild a Michigan 45AWS or 45R tractor shovel without the factory parts breakdown, you’re wasting time and risking ordering the wrong seal kit. I’ve seen it happen. A guy slaps in a generic bearing because the part number isn’t clear, and then the planet carrier eats itself at hour 50. That’s why you need the original Michigan 45AWS, 45R Parts Catalog – 98 pages of factory-issued exploded views, not some third-party rehash. Clark Equipment Company printed these in the U.S.A., and they don’t leave room for interpretation. Every section index references real part locations like “1 B7” for the front brake assembly. You follow the book, you get the right part.

Working on a shovel means you deal with hydraulic lines, brake clusters, and wiring that can short out if you mix up a connector. This catalog covers all that without the fluff. Let me walk you through what’s inside.

Brake Group Breakdown: Front and Rear Axle Assemblies

Brake systems on these machines are not forgiving. The Brake Group section includes separate entries for front and rear brake assemblies (1 B7 and 1 B9), foot brake controls (1 B10), the power cluster assembly (1 B12), and the main brake system (1 B14). You also get the parking brake lever and linkage (1 C2, 1 C3). If you’re chasing a drag or a leak, those exploded views show you the exact seal kit and spring orientation. Don’t guess – match the part number from the factory diagram.

Where Do You Find the Wiring Diagram?

Wiring is buried under the Wiring Group – see index “Wiring Group” on page 1 G6 through 1 G10. That includes the full Wiring Diagram (1 G9), plus the cab light kit, nameplates, and even the tool kit. If you’re chasing a short or adding a light, the diagram shows the factory routing. Aftermarket wiring diagrams for these old Clark machines are usually hand-drawn garbage. Stick with OEM.

7 Major Systems Covered in This 98-Page Parts Catalog

• Axle Group – front and rear axle assemblies, differential carriers, planet carriers
• Brake Group – full brake system including power cluster and parking brake
• Hydraulic Group – reservoir, lines for front equipment, steering, transmission
• Transmission Group – assembly, clutch groups (forward/reverse/low and high), controls
• Converter Group – converter assembly and pressure regulating valve
• Cylinder Group – boom, bucket, and steering cylinders
• Wiring Group – electrical equipment, wiring diagram, cab lights

Each group has its own page references like “1 D2” for the converter assembly. That lets you flip directly to the part you need without scanning 98 pages blind.

Converter and Cylinder Groups: What the Manual Shows

The Converter Group breaks down the converter assembly (1 D2) and the pressure regulating valve (1 D3). If your machine slips under load, you’ll be digging into that valve stack. The Cylinder Group gives you the boom, bucket, and steering cylinders (1 D4–1 D6). Each drawing includes every O-ring, piston seal, and rod wiper. I’ve seen guys order the wrong boom cylinder rebuild kit because they thought “it looks the same” – this catalog ends that.

Does This Parts Catalog Cover Both 45AWS and 45R?

Yes. The manual title on page 1 says “Model 45AWS & R Tractor Shovel.” The index is primarily written for the 45AWS, but the same part numbers apply to the 45R where noted. Always cross-reference your machine serial number – there’s a blank on the title page for that. If your serial falls outside the range covered, you may need the supplement. Check the Frame and Axle Cradle section (1 D9) for structural differences.

Why You Can Trust This Source (And Not a PDF from a Forum)

This is a direct scan of Clark Equipment Company’s Parts Manual No. 5004. No reprints, no redrawn diagrams. The PDF includes all 98 pages as originally printed, including the index pages (1 A1–1 A2) and the blank page for recording your machine serial number. I’ve used these for years – they match the yellow-painted parts on the shelf. If you’re serious about keeping a Michigan 45AWS or 45R running, this is the foundation.

Frequently Asked Questions

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values are in the separate service manual for these models.

Is the wiring diagram complete for the entire machine?

The wiring diagram (1 G9) covers the main electrical equipment and cab light kit. It shows harness routing and connector locations. However, it doesn’t include every single sub-harness for accessories like a heater or special light packages – those are in separate supplements.

Can I use this manual to rebuild my transmission?

You can use it to identify every part in the transmission assembly (1 F8) and clutch groups (1 F9–1 F10). For assembly procedures and clearances, you need the transmission service manual. This catalog gives you the part numbers to order the correct clutch discs and seals.

How many pages does the manual have?

98 pages.
