Michigan 45A Parts Catalog

Nobody likes pulling a brake cylinder off a 45A only to find the replacement part doesn’t match because you trusted a third-party parts list. That wasted time costs money, and on a machine this old, misidentified parts can turn a two-hour job into a two-day hunt. The Michigan 45A Parts Catalog puts the factory drawing and part number for every component in your hand. 96 pages, original OEM print, no reprints from some scan farm. This is the document the dealer used when these machines were still in warranty.

96 Pages of OEM Part Numbers

You get every major assembly broken down into individual parts with callouts and part numbers. The index starts with Accelerator Pedal and Linkage on page 1 and runs through to Wheels and Tyres on page 92. That includes the full brake system – Parking Brake Assembly, Wheel Brake, Brake Cylinder Front, Brake Controls and Lines – and all cylinder assemblies: Boom Cylinder, Bucket Cylinder, Steering Cylinder. No aftermarket manual writes the index this clean. You see exactly where each part lives. The page count is 96 because Michigan packed every detail without filler. You want the front brake cylinder exploded view? Flip to page 54. Need the steering cylinder? Page 66. Those numbers come from the actual printed manual, not a guess.

Brake and Cylinder Sections: Find Them Fast

Brake work on a loader this size needs the right lining and cylinder seals. The catalog devotes separate pages to the Parking Brake Assembly (page 10), Wheel Brake (pages 53, 59), and Brake Cylinder Front (page 54). You also get Brake Controls and Lines on page 18, and Parking Brake Controls on page 19. For hydraulic cylinders, the Boom Cylinder (page 65), Bucket Cylinder (page 65A), and Steering Cylinder (page 66) are all isolated with their own part-number tables. No flipping back and forth between unrelated sections – each cylinder gets a dedicated page. If you are rebuilding a steering cylinder, turn to page 66 and see the seal kit number immediately. That saves you the headache of ordering a kit that fits a different model.

Can You Use This Manual for a 45A from 1965?

Record your machine serial number on the cover page (the manual has a blank for it). Michigan built these tractors over several years, and parts superseded over time. The manual covers the baseline 45A Tractor Shovel. If your serial number falls outside the range documented, cross-reference with the latest service bulletins. But for the vast majority of 45As still working, this catalog gives you the original part numbers. The Electrical Wiring Diagram on page 35 uses the factory harness layout – aftermarket diagrams often reroute grounds. Stick with OEM if you want a harness that matches the pinout.

Michigan 45A Parts Catalog – Factory Parts Breakdown

Aftermarket parts books for construction equipment are notorious for swapping in generic illustrations. This catalog uses Michigan’s own engineering drawings. Every bolt, seal, and bushing is called out with the factory number. The bucket level valve (page 22), the torque converter assembly (page 90), the main control valve (page 69) – all factory-fresh. I’ve seen a Automotive Industry Overview that explains why OEM documentation carries more legal weight in equipment disputes. That matters if you are rebuilding a machine for resale or fleet compliance. The Automotive Industry Overview also notes how original parts sources reduce liability. This catalog is that source.

Index Structure: Accelerator Pedal to Wiring Diagram

Scan the index once and you will understand why aftermarket clones fail. Michigan lists every item alphabetically with page numbers. Accelerator Pedal and Linkage: 1. Air Cleaner System: 5. Battery: 16. Counterweight: 25. Electrical Wiring Diagram: 35. Fuel Tank: 45. Front Drive Axle: 49. It even includes the Tool Kit (page 91). You will not guess where the Planet Spider for the front axle lives – it is right there on page 52. The index is the fastest way to find any numbered part on your machine.

That is the point. Original OEM print with no third-party edits.

Can I identify a brake cylinder part number from this catalog?

Yes. Page 54 shows front brake cylinder parts.

What if I need a part that is not in the index?

The index covers 96 pages of every major assembly for the 45A: from the Accelerator Pedal and Linkage on page 1 to the Wheels and Tyres on page 92. If a part is missing, it likely belongs to an aftermarket modification. The OEM catalog only includes factory-installed components. Check the Electrical Wiring Diagram on page 35 for harness parts. For steering cylinder components, see page 66. Contact Michigan with the machine serial number if something is absent. They can cross-reference to superseded parts. This manual is the definitive list for original equipment. Do not expect it to include rebuilt or generic alternatives. If you have a 45A built after the catalog was printed, some part numbers may have been updated. Always verify with the latest factory service bulletins. The catalog is a snapshot from the time of publication, but it is far more reliable than any aftermarket compilation.
