Michigan 65AWS, 65R Parts Catalog – 270-Page Factory Manual

If you’re chasing parts for a Michigan 65AWS or 65R tractor shovel and relying on aftermarket cross‑reference sheets, you’ve already lost time. I’ve seen guys order a brake wheel cylinder three times because the catalog number didn’t match the real casting. That’s why you need the Michigan 65AWS, 65R Parts Catalog – the factory‑issued book that Clark Equipment Company printed for dealers. It shows every nut, seal, and cylinder with the part number you actually need to put in the order.

This thing is 270 pages of exploded diagrams, group numbers, and index‑driven part callouts. The index alone covers everything from Bucket Cylinder Assembly (50B) to the Brake System—Main (63) and Valve Group Tie Rod Assembly (56C). You flip to page 64 for the Brake Wheel Cylinder—Front, or page 73 for the Front‑Rear version. No guessing. No calling back the supplier.

Bucket Cylinder Assembly and Steering Cylinder (50B, 51A)

The manual breaks down every major hydraulic cylinder group. Bucket Cylinder Assembly (50B) and Steering Cylinder Assembly (51A) each have their own exploded view with individual part numbers for seals, pistons, rods, and end caps. If you’re rebuilding a cylinder, you get the exact OEM part number – not some generic kit that leaves you with leftover O‑rings. The valve group sections (Control Valve—Main Hydraulic, Pressure Relief Valve Steering) also reference the same cylinder components so you can trace a leak from the pump to the cylinder without mixing up cross‑references.

Brake Group: Factory Diagrams for Every Component

Brakes on a 65AWS are not something to skim over. The manual dedicates sections to Brake Assembly—Front (53A), Brake Assembly—Front‑Rear (65), Brake Wheel Cylinder—Front (64), Brake Wheel Cylinder—Front‑Rear (73), and the Brake System—Main (63) plus Air Reservoir (74A) and Brake Valve Assembly (73B). Every air line, unloader valve, and power cluster is diagrammed. I’ve seen aftermarket brake catalogs list one part number for all wheel cylinders – that gets a machine stuck on blocks. This manual shows you the difference between front and front‑rear wheel cylinders. Page 64 has the front brake wheel cylinder; page 73 has the front‑rear. Two different part numbers. Two different bore sizes. Don’t mix them up.

3 Reasons Factory OEM Beats Aftermarket Trash

First, the part numbers in this catalog were assigned by Clark Equipment Company. They match the casting numbers on your actual machine. Second, the exploded diagrams show hardware orientation – snap rings, washers, seals – in the exact order they come off. Aftermarket diagrams often flip or omit parts. Third, the valve group and transmission group sections (e.g., Control Valve—Transmission 27C, Transmission Assembly 26A) list internal parts like clutch packs and planetary gears that aftermarket suppliers don’t even stock. You get the OEM reference, then you know what to ask for at the dealer. For related manuals, see Michigan 65R Parts Catalog – OEM Factory Parts Manual.

Hydraulic Pump Group and Converter Assembly

The parts catalog covers three separate pump groups: Pump—Main Hydraulic, Pump Hydraulic—Front End, and Pump—Steering Hydraulic. Each pump assembly has its own page with drive couplings, seals, and mounting brackets. The Converter Group (Converter Assembly 2 4A) and Pressure Regulating Valve Assembly 25 are also included. If you’re swapping a converter or need a pump rebuild kit, the part numbers here are the ones the factory used. I’ve seen guys order a pump for a 65R that came off a 65AWS and wonder why the bolt pattern didn’t match – this manual’s pump sections are model‑specific. The index even separates Steering Gear (Orbitrol) 44 and Steering Unit (Orbitrol) 76 – two different assemblies for the same machine. You need the page number from the manual to order the right one.

Transmission and Axle Group Breakdown

Axle Assembly—Front (45), Axle Assembly—Rear (54), Differential & Carrier Assembly—Front (38) and Rear (42), Planet Carrier Assembly (42B) – all laid out with individual part numbers. The Transmission Group section runs from Transmission Assembly 26A through the clutch groups (Forward and 2nd Clutch Group 28A, Clutch Group—Forward, Reverse and Low 28B, Clutch Group—High 29B). If you’re rebuilding a transmission, you get the seal kit part number and the gear count for each clutch pack. The wiring diagrams and Battery—Battery Carrier and Wiring (26D) section are also factory‑sourced – not aftermarket scribbles. When ordering parts, always state model and serial number, as it says on every page of the manual.

FAQ – Michigan 65AWS, 65R Parts Catalog

Does this catalog cover the 65AWS and the 65R?

Yes. The manual is titled Model 65AWS & R. The index lists both models together, with separate sections where parts differ (e.g., brake wheel cylinders).

Why should I buy this instead of a third‑party parts list?

Because third‑party lists are compiled from memory or copied from other machines. This 270-page OEM parts catalog was printed by Clark Equipment Company. Every part number comes from the original engineering drawings. If you need a Brake Valve Assembly (73B) or a Pressure Relief Valve Steering, you get the exact number that Clark stamped on the part. Aftermarket lists often combine multiple models into one number, which means you get the wrong seal or the wrong casting. I’ve seen a 65R axle carrier ordered with a 65AWS differential carrier because the aftermarket list didn’t separate them. That mistake costs $1,200 and a week of downtime. This manual separates them on page 38 (front differential) and page 42 (rear differential). You get the right part the first time.

I’ve torqued more head bolts than most mechanics have had hot dinners, and I can tell you that using a factory parts catalog is the difference between a job that stays fixed and a job that comes back on a hook. This manual is 270 pages of pure OEM data. Get the right part numbers, keep your machine running. Access the factory manual.
