Michigan 35AWS 1973 Parts Catalog – OEM Factory Specs

If you have ever tried to order parts for an older tractor shovel using a generic aftermarket parts list, you know the frustration. The part number is wrong, the illustration doesn’t match your machine’s serial number range, and you end up with a box of metal that doesn’t fit. That stops here. This is the Michigan 35AWS 1973 Parts Catalog – the original OEM book from Clark Equipment Company, printed in the U.S.A. in 1973. It covers machine serial numbers 4179A101 ENG and after, and 4179A102 FSC and after. No reprints. No photocopies. This is the factory document that the dealer’s parts counter used when your machine was new.

Michigan 35AWS 1973 Parts Catalog: Engine and Brake Coverage

The alphabetical index in this 157-page manual breaks down every major system. Engine accessories are on page E12 – alternator, fan belt, filter elements, oil pressure sender, governor. Brake components fill pages B5 through B20: air lines (section A and section B), brake assembly, parking brake assembly, controls, pedal, power cluster, wheel cylinder assembly, and the air brake valve assembly on page V3. Each group is prefixed with a letter (e.g., B14 for Brake Assembly) and includes a page version number so you can tell if the illustration matches your machine’s build date. The manual explicitly states which serial numbers each revision applies to – something aftermarket catalogs ignore.

Air Brake Valve Assembly: Exactly Which Section to Check

Need the air brake valve assembly? Look under Valve – page V3 lists the complete assembly with part numbers for each component. The manual uses standard abbreviations (assy, brg, cyl, hyd) and symbols: a dagger means not illustrated, a section sign means not sold separately, an asterisk means as required. If a part carries a symbol, you know before you order whether it’s available or needs to be sourced as a subassembly. The valve section also covers the bucket leveler valve (V4), four-wheel steer selector valve (V5), main control valve (V7), steering control valve (V11), and transmission control valve (V15). That kind of detail belongs on your bench, not in a PDF that claims to cover “everything.”

What Makes This 1973 Manual Different from Aftermarket Reprints?

I have seen aftermarket parts catalogs that copy the cover art but omit the serial number table, then fill the rest with generic exploded views that don’t match any actual production run. This manual came from Clark Equipment Company. The first page tells you to record your machine serial number and to order through your nearest Clark distributor. The parts groups are arranged alphabetically, each with its own page numbering and revision number. If a design change happened during production, the manual notes it by revision. You are not guessing. You are reading the exact document that the line engineers used when assembling these tractors. Another useful companion is MICHIGAN 35AWS Tractor Shovel Parts Manual No. 2988.

3 Reasons to Stick with the Original Factory Parts Catalog

First, the exploded diagrams are drawn to the actual part geometry – you can count bolt holes and identify spacers without measuring. Second, every part number is tied to a specific machine serial number range. If your 35AWS falls outside the listed serial numbers, you know immediately that you need a later revision. Third, the manual includes the “WHEN ORDERING REPAIR PARTS” instructions up front: furnish quantity, part number, and description. No guesswork. That saves headaches.

Find the Right Part Number Without Guessing

The alphabetical index runs from Axle Differential Carrier Assembly (front, page A11; rear, page A13) to Cab Assembly (Z3) and beyond. Each entry leads to a page with a clear heading, part callouts, and a table of part numbers. For example, the boom cylinder assembly is on page C8, the bucket cylinder assembly on page C9, and the steering cylinder on page C10. If you are rebuilding a converter or transmission, the hydraulic system section (H11) shows the converter charging pump, filter elements, and all valves. The manual also covers frame assembly (F3), fuel tank and lines (F6), electrical gauges (E3), wiring and battery cables (E9), color codes (E11), and even decals and nameplates (N2). For context on equipment parts documentation, see Automotive Industry Overview. For background on equipment parts, the Automotive Industry Overview provides context.

Does this manual cover the bucket linkage and indicator?

Yes. Bucket Linkage & Indicator is on page B23.

Can I use this manual for a 35AWS built after the serial numbers listed on page 1?

The manual explicitly states: “Information Contained Herein Pertains to Machine Serial Numbers Listed Below: Perkins: 4179A101 ENC & After; 4179A102 FSC & After.” If your machine has a serial number after those, you need a later revision parts manual. The manual includes a page version number on each page (e.g., A1-1, A1-2) that tracks design changes. If a specific part page shows a higher revision number than what your machine’s serial number falls under, that part may not be correct for your build. Always cross-reference your serial number with the manual’s stated coverage before ordering any parts.

That 157-page document belongs in your shop. It will save you from buying the wrong brake wheel cylinder assembly or ordering a bucket cylinder that was superseded three revisions ago. Access the Factory Manual now and put the OEM parts catalog on your tablet or print binding.
