Clark-hurth 175A Parts Catalog

I’ve seen more than a few jobs go sideways because someone ordered the wrong part number. You pick up a seal kit off the shelf, it looks right, but the O-ring groove is a half-mil off, and now you’ve got a cylinder leak on a Friday afternoon. The Clark-hurth 175A Parts Catalog fixes that. This is the original factory document – 168 pages of indexed part numbers, exploded views, and assembly breakdowns for the Michigan Tractor Shovel Series II. No aftermarket interpretation. No guesswork. If you’re rebuilding a brake chamber, a steering cylinder, or the entire hydraulic system, you need the part number the plant stamped on the line. This manual gives you that.

Get the Right Part Number Every Time

Aftermarket parts suppliers will tell you their cross-reference works “for most applications.” That’s not good enough when you’re pulling a front brake assembly on a 175A that’s been sitting in a yard for ten years. The Parts Catalog lists every component by OEM number – from the Brake Assembly – Front (page 48) to the Boom Cylinder Assembly (page 68). You’ll find the exact part number for the seal kit, the piston, even the retaining hardware. I’ve used these catalogs to source NOS parts for a 175A that’s been out of production for decades. It’s your cheat sheet against buying the wrong pin and bushing kit.

If you need a specific section, the Clark 175A Tractor Shovel Parts Manual”>Clark 175A Tractor Shovel Parts Manual covers the entire machine.

Boom Cylinder Assembly: Exploded Views and Part Numbers

You’re on page 68 and the Boom Cylinder Assembly drawing shows every nut, seal, and rod. The part numbers are called out with a leader line. No need to guess which O-ring goes where – it’s right there. The same for the Bucket Cylinder Assembly on page 69 and the Steering Cylinder on page 56. When you’re rebuilding a cylinder bank, you need to know if the piston seal is a different width from the rod seal. This catalog tells you. I’ve rebuilt three 175A boom cylinders using this exact manual, and every seal matched the first time.

Brake Controls and Air Lines: Page 45-46

Brake safety isn’t optional. The Brake Controls section (page 45) and Brake Air Lines (page 46) show the routing and part numbers for the air chambers, hoses, and fittings. The Front Air Chamber (page 35) and Rear Air Chamber (page 37) are separate listings, because they’re not interchangeable. If you’re working on the Parking Brake Assembly (page 50), the manual includes the lever, linkage, and cable part numbers. One wrong brake valve could cost you a machine – or worse. Use the factory diagram.

Converter Assembly and Differential: Pages 29-30 and 39-41

The converter and differential sections are where I’ve seen guys get burned the most. The Converter Assembly is spread across pages 29 and 30. The Differential and Carrier Assembly – Front (page 39) and Rear (page 41) have different part numbers for bearings, shims, and ring gears. The parts catalog breaks out the planet spider assembly (page 42) and propeller shafts (page 43). Before you order a differential rebuild kit, verify the serial number against the listings in this manual. A 175A Series II with a 4HG999 serial number might have a different carrier than one with 3HG101. The catalog notes that.

What Does the Brake Section Cover?

The Brake Assembly – Front (page 48), Brake Assembly – Rear (page 49), and Parking Brake Assembly (page 50) each get their own exploded view. The catalog also includes the Brake Controls (page 45) – which covers the pedal, linkage, and valves – and the Brake Air Lines (page 46) with hose lengths and fitting sizes. If you’re replacing air chambers, the Air Chamber, Front (page 35) and Air Chamber, Rear (page 37) list the diaphragm, return spring, and clamp ring part numbers separately. I’ve used this to order a diaphragm kit for a 175A that had a leaking rear chamber; the parts guy thought I needed a whole new chamber until I showed him the page.

Does this parts catalog include torque values or service procedures?

No. This is a parts catalog, not a service manual. It lists part numbers, exploded views, and quantities. For torque specs and rebuild procedures, you need the service manual. The catalog is designed to help you order the correct replacement parts before you start the job.

Can I use this catalog to identify parts for a 175A with a Cummins engine?

Yes. The manual covers both the G.M. (3HG101–4HG999) and Cummins (4HC101–4HC999) serial number ranges. Engine-specific sections are clearly labeled – for example, “Air Cleaner Assembly — G.M.” on page 11 and “Engine Controls” on page 14 apply to the G.M. version. The Cummins versions have separate listings where components differ. Always check your machine’s serial number against the ranges in the header.

If you’re tired of ordering the wrong brake shoes or cylinder rebuild kits, you need the factory source. This 168-page Parts Catalog is the same book the dealer’s parts counter uses. Access the Factory Manual and get the right part number every time.
