Michigan 45 AWS Parts Catalog – Factory OEM Parts Breakdown

After 28 years of turning wrenches, I’ve seen one too many guys order a brake valve from an aftermarket catalog, bolt it on, and then wonder why the pedal goes to the floor. The part number looked right in the cross-reference, but the port orientation was off. That’s a half-day wasted and a machine down. If you are working on a Michigan 45 AWS Parts Catalog, you need the factory numbers – not a third-party guess. This is the original, 212-page binder from Clark Equipment, printed in Belgium. It tells you exactly what goes where, from the Wiring harness to the last Brake wheel Cylinder. Every Valve assembly, every Cylinder – it’s all in here.

Battery, Carrier & Wiring – Getting the Electrical Parts Right

Page 23 covers the battery carrier and the complete wiring harness layout. If you are chasing a no-start because some previous owner spliced in a generic harness, you need the factory routing and the correct part numbers for the connectors. This section shows the carrier mounting, cable lengths, and the battery hold-down hardware. Without it, you are playing twenty questions with your parts guy.

Brake Assembly and Valve – Why OEM Part Numbers Matter

The Brake assembly (pages 49, 54) and the Brake Valve Assembly (page 64) are critical safety items. The manual gives you the exploded view of the valve body, the seals, the spring kits – all with original Clark numbers. The Brake wheel cylinder (page 50, 55) is a common failure point, and the aftermarket replacements often have different bore sizes. You want the factory spec, not a close-enough. One wrong seal and you lose a pedal.

Boom Cylinder Assembly and Bucket Cylinder – Hydraulic Part Identification

Hydraulic cylinders on a loader take a beating. The Boom Cylinder Assembly (page 60) and Bucket Cylinder Assembly (page 61) are broken down into every gland, piston, and seal. The manual lists the exact O-ring and backup ring dimensions. If you are rebuilding instead of replacing, you need these pages. I have seen guys order a seal kit that “fits” only to find the rod diameter is a few thou off. That’s a leak waiting to happen.

Control Valve and Transmission – Avoiding Cross-Reference Headaches

The Control Valve for front-end equipment (page 9) and the control valve for the transmission (pages 47, 52) are completely different animals. The parts catalog shows the exact spool configurations and the relief valve settings. There is a pressure regulating valve for the torque converter on page 44 and a pressure relief valve for steering on page 56. If you are swapping a valve, you need the correct spring rate. The manual gives you the original part numbers – not a “will-fit” number that could let all the oil dump to tank.

This is 212 pages of factory-engineered information. The index at the front groups every system: air cleaner, axle, battery, boom, brake, bucket, cab, clutch, differential, electrical, engine, fuel, hydraulic, lights, muffler, planet carrier, propel shafts, radiator, seat, steering, tie rod, torque converter, transmission, wheels. Everything has a page reference.

Who Needs This 212-Page Parts Catalog?

If you own a Michigan 45 AWS with the Perkins engine, this is the only parts list you should trust. It is for the owner-operator who wants to order the right part the first time. It is for the shop that has a customer’s loader down and needs to find that obscure bushing in the bucket leveller (page 7). It is for the restorer who wants to bring the machine back to original condition. Beginners: do not try to identify a part by looking at a blurry photo online. Use the factory breakdown. You will save yourself the return shipping fees.

Source Authenticity – Factory Print, Not Aftermarket

This is a scan of the original Clark Equipment publication. The inside front cover tells you to always furnish the distributor with the machine serial number and to use genuine Clark parts. There is no third-party reprint, no aftermarket interpretation. The part numbers are the numbers that came from the factory. If you need the Valve for the bucket leveller, page 28 shows it. The Wiring is on page 23. The Brake controls and lines are on page 65. Every number matches the original engineering drawings. That is what you pay for when you buy a factory manual.

Does this catalog include service procedures or torque specs?

This is a parts catalog, not a service manual. It shows exploded views and part numbers for ordering. No step-by-step repair or torque values.

How do I find a specific part like the steering cylinder seal?

Use the index at the front. Steering Cylinder Assembly is listed. Turn to that page (page 6). The exploded drawing includes callouts. Match the callout number to the part number list below the drawing. Then reference the part number when ordering. I always write the number and the machine serial on the order form – avoids mix-ups. The manual also includes a tool kit section (page 3) and nameplates/decals (page 35) so you can order replacement decals for the cab. If you need the brake power cluster, it is on page 29. The transmission clutch groups (high, low, reverse) are on pages 27 and 36. It is all cross-referenced. Expect to spend a few minutes with the index – it saves hours of pulling the wrong boxes off the shelf.

I have been doing this long enough to know that the difference between a flat-rate job and a come-back is the parts you put in. When you order from the factory number, the parts fit. Period. This Michigan 45 AWS parts catalog gets you those numbers. If you are serious about keeping that loader running without chasing ghosts, VOLVO BM 125C Wheel Loader Parts Catalog is also a solid resource for similar vintage machines. For more Michigan-specific options, check the Michigan 851 Parts Catalog – 72-Page Factory Parts Manual for larger loaders or the Michigan 85III 1965 Parts Catalog – Factory OEM Parts Breakdown for the older 85 series. And if you want to understand how the automotive equipment industry works under the hood, read the Automotive Industry Overview and Automotive Industry Overview for context – but the parts numbers stay the same. Access the Factory Manual and get the right parts on the shelf before you start the tear-down.
