Michigan 85 III A Parts Catalog – Factory OEM Documentation

You are rebuilding a Michigan 85 III A, and the parts list from a third-party site sent you the wrong bearing. I have seen that happen. A machine that old needs the original factory breakdown, not some scanned copy that skipped pages. This Michigan 85 III A Parts Catalog is the real deal — 216 pages of OEM part numbers, exploded views, and assembly references that match the original Clark Equipment print. Every cylinder, brake line, and valve in this book came from the same factory that built the tractor shovel.

The table of contents alone lists over 90 sections, from the Air Cleaner Assembly (page 6) to the Wheel and Tire Data (page 87). You get the index for the MODEL 85 III A at the front, cross-referencing every system. That index alone saves you an hour of flipping pages when you need a part number fast.

I have been wrenching for 28 years and I have seen too many techs order the wrong brake assembly because a generic catalog didn’t clarify front vs rear. Page 71 shows the Brake Assembly – Front, page 78 shows the Rear. No ambiguity.

Aftermarket documentation? I trust it about as far as I can throw a torque wrench. They often re-label part numbers or omit critical seal kits. This Parts Catalog is a direct scan of the original Clark publication — the same one a dealership would have pulled off the shelf in the 1970s.

Boom Cylinder Assembly and Bucket Components

The cylinder groups are laid out with the part number for every seal, pin, and bushing. The Boom Cylinder Assembly sits on page 24; the Bucket Cylinder Assembly on page 25. If you are replacing a blown boom seal, you need the exact kit — the catalog lists it. The Bucket Leveler Valve on page 43 tells you which spool and spring go where. No eyeballing parts from a blurry photo.

What Does the Brake System Section Cover?

Everything from the air brake valve (page 81) to the parking brake lever assembly (page 84). The Brake Lines are on pages 79-80. The front and rear assemblies are separate — page 71 and page 78. The Brake Controls – Parking (page 85) and Brake Foot Controls (page 86) give you the pedal and linkage parts. If you are chasing a low pedal, start with the master cylinder section? Not here — that is a service manual thing — but the catalog will get you the correct master cylinder part number.

3 Major Valve Groups in This Parts Catalog

The valve coverage is deep. The Pressure Regulating Valve Assembly (page 59) handles the hydraulic system pressure. The Control Valve Assembly – Transmission (pages 50-52) is critical for shifting. The Main Controls Valve Assembly (page 53) runs the loader functions. Each page groups the body, spools, springs, and hardware. You can rebuild a valve stack without guessing which o-ring goes where.

Understand the Hydraulic System Reference

The Hydraulic Oil Reservoir (pages 30-31) and the Steering Hydraulic System (pages 32-33) are separated from the Transmission and Torque Converter hydraulics (pages 34-35). That matters when you are tracing a leak. The Steering Cylinder Assembly is on page 26. The Pump, Main Hydraulic (page 22) and Pump, Steering Hydraulic (page 23) list the exact displacement and mounting.

Steering and Axle Assemblies: Factory Part Numbers

The Steering Gear Assembly (pages 37-38), Drag Link (page 39), and Linkage (page 36) come with enough detail to order a complete overhaul kit. Axles: Front Drive (pages 66-67), Rear Drive (pages 73-74), plus the Differential and Carrier (pages 68-69 and 75-76). Planet Carrier assemblies (front page 70, rear page 77). If you need an axle shaft seal, the part number is right there.

OEM vs Aftermarket: Why the 216-Page Original Wins

Aftermarket parts catalogs often combine multiple models into one book to cut costs. That leads to confusion when the part number for the 85 III A differs from the 85III. This Parts Catalog is model-specific — Michigan 85 III A only. The 216 pages include the Wiring Diagram (page 91), Cab Light Kit (page 95), and even the Tool Kit (pages 98-99). Every page is a direct scan, not a reprint with new formatting. For a broader look at how these machines fit into the industry, see the Automotive Industry Overview. Related manuals like VOLVO BM 125C Wheel Loader Parts Catalog and Michigan 851 Parts Catalog – 72-Page Factory Parts Manual use the same drawing format. Michigan Model 85III Tractor Shovel Parts Manual No.66 is a different model — verify your serial before ordering.

That is why you want the original.

Is this the same as a service manual?

No. This is a parts catalog with exploded diagrams and part numbers. For repair procedures, you need the service manual.

Does this manual include torque specs?

No. Torque values belong in the service manual. But the parts catalog lists the correct fasteners and assemblies needed for replacement.

How are the parts organized?

By major systems like engine, transmission, brakes, hydraulics. Each section has an index page listing component groups. Exploded views with callouts correspond to a parts list table with part number, description, quantity per machine. The front cover has spaces to record machine and engine serial numbers. Cross-references in the index at the back. For example, the Boom Cylinder Assembly on page 24 shows the cylinder body, rod, seals, pins, and each part number. This prevents ordering wrong parts. The steering gear section (pages 37-38) breaks down every gear and bearing. For the brake system, you can identify the exact wheel cylinder part for front vs rear. The catalog does not mix models — it is strictly the 85 III A, so you never get a part number for the 85II by mistake.

What years does this cover?

This manual is for the Michigan 85 III A tractor shovel produced by Clark Equipment. No specific year listed.

Check the serial number on your machine, then Access the Factory Manual from AutoRepairManuals and keep it on your bench. Automotive Industry Overview shows why OEM documentation matters for heavy equipment.
