Michigan 45B Parts Catalog

Every time a machine sits idle waiting on the wrong part, you lose money. I’ve seen it happen with the Michigan 45B Parts Catalog missing from a shop shelf – a guy orders a boom cylinder seal kit based on a generic cross-reference, and it’s wrong. That’s a day wasted, maybe two. This catalog stops that. It’s the OEM document, 316 pages thick, listing every single production part for the Clark Michigan 45B Articulated Tractor Shovel – both Cummins and Perkins engine variants.

Alphabetical Index: Faster Than Guessing

The manual opens with a complete alphabetical index. Need the steering cylinder assembly? Look under “C” for Cylinder. Page references are right there. You don’t flip through random sections hoping to find the right exploded view. The index covers everything from Accelerator Pedal (1G12) to Wheel Studs – though that last one is implied by the sheer coverage. I’ve used aftermarket catalogs that skip half the brake system. This one lists Brake Air Lines for both engine options, separate entries for Front and Rear Axle Differential Carrier Assemblies (pages 1A18 and 1A24), and even the Grease Piping. That’s attention to detail.

Boom Cylinder Assembly – Part Numbers You Can Trust

Hydraulic cylinders are high-wear items, especially on a tractor shovel. The Boom Cylinder Assembly section (page 1D18) gives you an exploded diagram and the exact Clark part numbers for seals, pistons, rods, and bushings. You get the same info for the Bucket Cylinder (1D20) and Steering Cylinder (1D22). No third-party interpretation – these are the factory part numbers that Clark used on the assembly line. If you’re rebuilding a cylinder, you need the O-ring groove dimensions and the snap ring specs. The catalog doesn’t spell out torque values (that’s in the service manual), but it gives you the parts required to put it back together correctly.

Does the Manual Cover Both Cummins and Perkins Engines?

Yes – and it separates them by section. Look at the TOC: Engine & Transmission Mountings – Cummins (1G6) and Perkins (1G10). Electrical Wiring Color Code – two separate subsections. Fuel Tank & Lines, Engine Belts, Engine Controls … each one has a dedicated page reference for the specific engine. If you’re servicing a 45B that came from the factory with the Perkins 4.236, you don’t have to wade through Cummins data. The index and page layout were designed for the mechanic on a deadline. That’s the difference between OEM documentation and a generic “fits all” aftermarket book.

Axle Assembly Diagrams – Front and Rear

Drivetrain parts are expensive and heavy to ship wrong. The Axle Assembly, Front (1A6) and Axle Assembly, Rear (1A10) sections include the differential carrier assemblies, planet carrier assemblies, and brake disc components. If you need the planetary gear set for a front axle, you’ll find it under “Axle Planet Carrier Assembly, Front & Rear” (page 1B6). Each assembly drawing is labeled with Clark’s original part numbers. Compare that to a parts website that shows a blurry photo and says “fits many models” – no thanks. This manual came out of Clark Equipment Company, printed in the U.S.A., Form No. 2920-1.

316 Pages of Factory Specs – No Shortcuts

That number – 316 pages – tells you the level of detail. It’s not a condensed aftermarket reprint that shoves two assemblies onto one page to save ink. Every component, from the Battery & Battery Mount to the Cockpit Sound Proofing, has its own exploded view and parts list. The manual even includes a section on Decals (page 11 6) – critical for safety warnings on an articulated loader. Missing a decal that says “Keep Clear of Articulated Joint” is a liability you don’t want. This catalog lists placement and part numbers for those decals.

Source Validity: OEM Clark Manual – Not Aftermarket Hype

The PDF you get here is a direct scan of the original Clark Equipment Company publication. You can see the warranty notice on page 3, the serial number ranges (Cummins 437A101 & Perkins 4189A101), and the statement that it supersedes P-4873 dated 9-69. That means you’re holding the parts data that Clark themselves used. Aftermarket catalogs often re-index by manufacturer part number or try to cross-reference across brands – that’s where mistakes happen. Stick with the factory source. If you want to understand why OEM paperwork matters in the broader industry, check the Automotive Industry Overview – but for this machine, trust Clark’s own book.

You might also need the companion service manual. Related documents on site include Michigan Model 45B Articulated Tractor Shovel Parts Manual (this exact listing), plus MICHIGAN 45B Articulated TRACTOR SHOVEL Parts Manual (another copy with slightly different file origin).

FAQ

How are parts listed – by group or by machine serial number?

Alphabetical index with page numbers. Groups like “Axle Assembly” show multiple sections for front and rear. The manual covers serial numbers listed on page 1: Cummins from 437A101 and Perkins from 4189A101. Each assembly drawing notes any serial number breaks if components changed.

Can I use this catalog to order parts from a Clark dealer today?

Yes. These are original Clark part numbers. Modern dealers may have superseded numbers, but the catalog gives you the starting point. Cross-reference with your dealer using the numbers from the diagram.
