Michigan 55AWS, 55R Parts Catalog – 262 Pages of Factory OEM Parts Data

If you’re tearing into a Michigan 55AWS or 55R Tractor Shovel and you don’t have the factory parts breakdown in front of you, you’re gambling with someone else’s time and your own money. I’ve seen guys order the wrong brake wheel cylinder because they guessed from a blurry aftermarket scan. That’s a week of downtime and a pissed-off customer. This is a Michigan 55AWS, 55R Parts Catalog – 262 pages, original Clark Equipment print, part number No. 5008. It’s not a reprint. It’s not a third-party hack.

Brake Group: Factory Parts Breakdown

You need a brake assembly for the front or rear? Page numbers in the index point to the exact exploded view. The Brake Group section covers Brake Assembly — Front (1 C14), Brake Assembly — Rear (1 D4), Brake Lines — Main (1 D8), Brake Air Reservoir (1 E7), Brake Valve Assembly (1 E8), Brake Wheel Cylinder — Rear (1 E11), Brake Wheel Cylinder — Front (1 E12), Brake Power Cluster Assembly (1 E14), Brake Unloader Valve Assembly (1 F4), Foot Brake Controls (1 F7), Parking Brake Assembly (1 F9), Parking Brake Linkage (1 F10), and Parking Brake Lever Assembly (1 F12). Every part number is listed with the Clark OEM reference. You match the callout on the drawing, order the right piece, and move on. That’s how you keep a shovel running.

262 Pages of OEM Parts Data

This catalog covers both the 55AWS and 55R models – the index lists them together. You’ll find every group from A (accelerator pedal) through W (wiring). 262 pages means you have the complete exploded diagrams for the Axle Group – front and rear drive assemblies, differential and carrier, planet carriers. The Pump Group shows hydraulic pumps for front end equipment, main hydraulic, and steering. The Transmission Group has clutch groups for forward, reverse, low, high, and the control valve. None of this is generic description – every page is a factory drawing with callouts.

Does This Manual Cover the Steering and Hydraulics?

Yes, and it does it the way OEM manuals should. The Steering Group includes the steering gear assembly, Orbitrol unit, steering linkage, and tie rod assembly. The Hydraulic Group covers the reservoir, lines for front end equipment, steering lines, and the hydraulic system for transmission and converter. You want the pressure relief valve for steering? That’s in the Valve Group along with the bucket leveller valve and the front end control valve. All part numbers are original Clark Equipment – no “equivalent” substitutions.

For the converter and transmission, the Converter Group lists the converter assembly and pressure regulating valve. The Propeller Shaft sections show the shafts from converter to transmission, and from transmission to front axle. If you’re rebuilding the transmission, the Trans. — Clutch Group pages break down forward, reverse, low, high, and the control linkage. This is the kind of detail that keeps you from buying a whole transmission when you only need a clutch pack.

Get the Right Part Number the First Time

Aftermarket catalogs might list “brake wheel cylinder” as a generic item. This manual shows the exact Clark part number for the front brake wheel cylinder (1 E12) and the rear (1 E11). You don’t guess. You order from the drawing. Same for the Bucket Assembly Data (1 G5) – bucket teeth, indicator, leveller lines. If you’re replacing teeth, you need the correct part number for the tooth and the adapter. This catalog has it.

Axle Group: Front and Rear Drive Assemblies

The Axle Group is broken down into separate sections for front and rear drive axles. You get the differential and carrier assembly for the front (1 C4) and rear (1 C7), plus the planet carrier assemblies for both ends. The Frame and Axle Cradle section (2 C10) shows how the axles mount to the frame. If you’re pulling an axle, you need those exploded views to identify every seal, bearing, and shim. This manual gives you that.

Wiring group? Yes – battery, electrical equipment, wiring diagram (3 D10), cab light kit, nameplates and decals, tool kit, windscreen wiper kit. People often skip the wiring diagram because it’s a pain to read. But when your lights don’t work or the starter won’t crank, that diagram saves you from replacing good components. The factory diagram has the correct wire colors and connector locations.

Source Authenticity – Why OEM Beats Aftermarket

This is an original Clark Equipment Company manual printed in the USA. No reprint, no photocopy. Every part number is verified against the factory parts system. Aftermarket parts catalogs often redraw the illustrations and miss a bolt or a washer. Then you order what you think is a complete kit and come up short. With this 262-page OEM Parts Catalog, you see every component exactly as Clark designed it. The part numbers are the ones the dealer uses. That’s the difference between a one-day repair and a three-day wait for a missing snap ring.

Who Needs This Manual?

If you own a shop that services Michigan tractor shovels, or you’re a mechanic who’s been handed a 55AWS or 55R with a broken brake line or a leaking boom cylinder, this catalog is your parts bible. Home garage enthusiasts who do their own heavy equipment repairs will find the exploded views essential – even experienced guys get tripped up on the planet carrier assemblies if they don’t have the right part numbers for bearings and seals. Beginners: don’t touch the brakes without this manual. Brake systems on these shovels are air-over-hydraulic. One wrong part can cause a failure on a jobsite.
