Michigan 175A 1963 Parts Catalog – Tractor Shovel Parts Manual No. 203

If you’ve ever tried to order a replacement part for an old Michigan 175A tractor shovel using a third-party reprint, you know the drill: part numbers that don’t match, references to superseded parts, and the frustration of getting the wrong cylinder seal because someone guessed at the interchange. That stops here. The Michigan 175A 1963 Parts Catalog is the original factory document – 108 pages of exact part numbers, exploded views, and the critical note about interchangeability that aftermarket catalogs always leave out. This is the manual Clark Equipment published in 1963 for the 100-inch wheelbase tractor shovel. Every page came from the same print run that went to Michigan dealers. No reprints, no later revisions, no guesswork.

Page 3 of the catalog carries the note that made this document indispensable: part numbers prefixed with “IV” are identical to American parts and interchangeable; those with “AW” are British manufacture and may not swap. Miss that note, and you’ll order a brake chamber that doesn’t fit. That kind of detail is what separates a factory parts catalog from a generic list.

Part Number Prefixes: “IV” and “AW” Interchange

The single most important piece of data in this manual is the prefix system explained on page 3. If you are rebuilding a Michigan 175A that was assembled in the UK, you need to know whether your machine carries American-sourced or British-sourced components. The catalog flags every part with its group – “IV” for parts that interchange directly with the US version, “AW” for British-origin parts that may have different dimensions or thread pitches. Ignore this and you’ll be hunting for a steering cylinder that looks right but won’t bolt up. The manual covers that up front, not buried in a footnote.

What Does the 1963 Parts Catalog Cover?

This is a parts manual, not a service manual. It gives you exploded diagrams and part numbers for every assembly on the machine. The index lists sections for the Engine (page references to the separate Engine Manual), Boom and Guide Bar Assembly, Bucket and Carrier Assembly, Brake Assemblies (front and rear axle), Transmission and Torque Converter, Steering Hydraulic System, Wiring and Battery Holder, and more. You get 108 pages of factory line drawings with callouts. Need the part number for the bucket cylinder? It’s in the Bucket Cylinder Assembly section. Need the seal kit for the steering cylinder? The manual lists it under Cylinder Assembly – Steering System.

Boom Cylinder, Bucket Cylinder, and Brake Assemblies

Three systems that eat up shop time on these loaders: the boom hydraulics, bucket tilt, and brakes. The catalog gives you complete breakdowns. The Boom Cylinder Assembly (page 75) includes every seal, bushing, and piston ring with a factory part number. The Bucket Cylinder Assembly (page 76) is the same. For the brakes, you get separate sections for the Front Brake Assembly (page 77), Rear Brake Assembly (page 78), Parking Brake Assembly (page 81), and the complete Brake Controls (page 79) and Brake Lines and Fittings (pages 85, 87). If you’re rebuilding a caliper or replacing air chambers, you need these drawings to order the right hardware. Aftermarket catalogs often combine parts from different years – this manual is specific to the 1963 Model 175A.

Engine, Wiring, and Fuel System Parts

The manual references the Engine Manual for internal engine parts, but it does include the Engine By-Pass Oil Filter (page 19), Engine Controls (pages 17, 18), Fuel Filter and Cartridge (pages 21, 23), and Fuel Lines. For electrical work, the Battery Holder Wiring and Parts (page 92), Cables, Battery and Ignition (page 92), and Head Lamp Assembly (page 91) give you the factory wire colors and connector part numbers. The Instrument Panel Assembly (page 89) includes the hourmeter and gauges. If you’re chasing an electrical gremlin, this catalog tells you which switch or sender to order, not just a generic replacement.

Order with Certainty: Factory Specs Only

I’ve seen too many aftermarket parts catalogs that lift drawings from a 1965 manual and slap them into a 1963 listing. The Michigan 175A 1963 Parts Catalog is the original – published 13th February 1963 by Clark Equipment Limited, Camberley, Surrey. It is the only source that matches the exact production run of the 1963 Model 175A. The index alone spans 108 pages of specific assemblies: Transmission Control Cover Parts (page 33), Torque Converter Assembly (pages 39, 43), Steering Gear Assembly and Parts (page 59), Differential and Carrier Assembly (pages 51, 52). Every part number was verified at the factory. You don’t need to cross-reference a third-party database.

For the 175A-2 variant, see the related manual: MICHIGAN Model 175A-2 Tractor Shovel Parts Manual No. 204 – Section: Rea (Radiat. For the later revision with gear shift details, refer to MICHIGAN Model 175A Tractor Shovel Parts Manual No. 1363-R2 – Section: Gear Shif. And if you need the German-language parts list, check Michigan 175A Parts Manual (Ersatzteilliste).

Understanding the context of these machines helps. The Automotive Industry Overview gives background on how equipment manufacturers standardized part numbering. For more on British versus American sourcing, see Automotive Industry Overview.

That matters.

If you own a Michigan 175A tractor shovel and you’re tired of ordering parts that don’t fit, this is the catalog you need. Access the Factory Manual and get the right part the first time – no reprints, no aftermarket confusion.

Frequently Asked Questions

Can I use this catalog to order parts for my 175A engine?

Yes, the engine section is listed in the index.

Does this include wiring diagrams?

The manual covers battery holder wiring and parts on page 92, cables and ignition, and the horn push/dip switch. For full engine wiring diagrams and temperature sender details, the index references a separate Engine Manual. This catalog gives you the part numbers for all electrical components – switches, lamps, sender units – but the schematic is in the service manual.

What about the brake system – are all parts listed?

The catalog covers front and rear brake assemblies, parking brake, brake controls, brake lines, and the E.I. foot valve. Page references are given for each subsection, so you can find the exact part number for your axle configuration.

How is this different from a service manual?

A service manual tells you how to take it apart and put it back together. This parts catalog tells you what part number to order. You need both for a full rebuild, but without the parts catalog you’re ordering blind.
