Clark-hurth 85A, 85A1 1978 Parts Catalog

If you’ve ever ordered a part for an old Clark-hurth loader based on a blurry photo and a prayer, you already know why this catalog exists. I’ve seen guys pull a torque converter out of a 85A1, measure the bolt pattern, and still get the wrong seal because they used an aftermarket cross-reference. That’s wasted time and money. This is the factory parts book – the same one Clark-hurth issued in 1978 to dealers and service shops. It tells you exactly which part number fits which serial number break, and it shows you the exploded view so you can see how things stack. No third-party rehashes.

140 Pages of Factory-Gridded Parts Breakdowns

Every page in this 140-page catalog uses the Clark grid system. You’ll see sections like 1A6 Accelerator Pedal and Linkage or 1B2 Axle Assembly-Front Drive. Each grid has an illustration reference (like TP1018) and a write-up column that tells you if the part numbers are listed. Some grids are empty because the illustration covers multiple sections – pay attention to the “None” entries. That’s not a mistake; it means the same drawing applies. For example, the **Engine Assembly** section starts at 1E4, and you’ll find engine support parts and fuel line routing in the same area. Page 73 shows the torque converter assembly breakdown – if you need the charge pump parts, that’s where you look.

What Makes an OEM Parts Catalog Different from Aftermarket?

Aftermarket parts catalogs often combine multiple models into one generic list, then tell you to “verify fitment.” That’s fine for a lawnmower. Not fine for a machine where the 85A and 85A1 have different axle assemblies. This catalog has separate index entries for Model 85A1 (section 1A1) and breaks out front drive vs. rear drive steer axles. The **Differential and Carrier Assembly** section (1B12 through 1C1) includes the part number suffix that changed in late production. You don’t have to guess – the grid tells you which illustration matches your machine’s serial number range. That’s the kind of detail aftermarket houses skip because it’s expensive to reproduce.

Torque Converter and Axle Sections: Where You’ll Spend Most of Your Time

If you work on these loaders, you know the torque converter is a trouble spot. The catalog covers **Torque Converter Assembly** from 1D7 to 1D12, plus the **Pressure Regulator Valve Assembly** at 1D13. You get the exploded view of the converter housing, stator, and pump drive. Same for the axles: **Axle Assembly-Front Drive** (1B2-1B5) and **Axle Assembly-Rear Drive Steer** (1B7-1B11) have separate part numbers for seals, bearings, and planet gears. I’ve rebuilt a rear steer axle on a 85A1 using this catalog – the part numbers on page 54 matched the original stamped numbers on the housing. No cross-referencing needed.

Engine and Fuel System Coverage: What’s Here and What’s Not

This is a parts catalog, not a service manual. So you won’t find torque specs or rebuild procedures. But you will find every engine component bracket, gasket, and fuel line section. The **Engine Assembly** (1E4) shows the long block with mounting parts. **Fuel Lines** runs from 1E9 to 1E14, with separate grids for each line segment. There’s also **Engine Stop** (1A11) and **Air Cleaner and Attaching Parts** (1A12-1B1). If you’re chasing an air intake leak, having the correct clamp part number saves you from buying a whole assembly.

3 Reasons You Need This Catalog on Your Bench

First, it eliminates the “I think this is the right part” calls to the supplier. Second, it shows you the exact orientation of brackets and lines – the illustrations are to scale, not cartoonish. Third, it covers both the 85A and the 85A1 in one book, so if you maintain a mixed fleet, you only need this one catalog. Check out the related manuals if you need the service procedures: Clark Michigan L320 Wheel Loader Parts Catalog 1991, Clark Michigan 85III Tractor Shovel Parts Manual (1965), and Clark Michigan Wheel Loader 75C Parts Manual cover other models in the same family.

Get the Right Part Number the First Time

Don’t trust web forums or old sticky notes. This is the same document Clark-hurth sent to parts counters. It’s scanned from the original 1978 print, so every page is crisp – no smudged numbers. For context on how these machines fit into the broader industry, see the Automotive Industry Overview and the basics of the Internal Combustion Engine. But for your Clark-hurth 85A or 85A1, this parts catalog is the only reference you need.

Does this catalog include service procedures or torque specs?

No. This is a parts catalog only. It lists part numbers and exploded views. No repair instructions. You need the service manual for torque values.

Can I use this catalog for both the 85A and the 85A1?

Yes. The catalog has a separate index for Model 85A1 (section 1A1) and covers both models side by side. Pay attention to serial number breaks noted in each section.

What if my machine has a serial number that falls between the breaks listed in the catalog?

Call Clark-hurth or check the component casting date codes. The catalog uses the serial number breaks that were current at publication. Later production changes may not be reflected, but for the majority of 1977-1980 units it’s accurate.

Are the illustrations clear enough to identify small parts like seals and O-rings?

Yes. The factory line drawings are detailed. Each part is keyed to a number in the illustration, and the write-up column lists the part number. Some seals are called out as “seal, oil” with the specific dimensions. If the illustration is too small, use the grid number to locate the part on the opposite page.
