Clark-hurth 125A Parts Catalog – 164 Pages of Factory Specs

If you’re trying to rebuild a Clark 125A tractor shovel without the original parts catalog, you’re burning time and money. I’ve seen guys order the wrong bucket cylinder because they didn’t have the right part number. This manual—the genuine Clark-hurth 125A Parts Catalog—solves that. 164 pages of exploded-view drawings with factory part numbers, sorted by system. No aftermarket reprints, no generic interchange lists. This is the same document Clark Equipment Company printed in 1980, with serial number ranges for both Waukesha and G.M. engine models. You get the exact part numbers you need, organized the way the factory designed the machine.

Axle Assembly Breakdown: Front Drive and Rear Steer

The front drive axle assembly lives on page 57. The rear drive steer axle shows up on pages 59 and 60. Each page has an exploded diagram with callouts matching the part number list. If you’re replacing axle shafts, bearings, or steering knuckles, you pull those pages, identify the part by the number in the diagram, then order from your Clark distributor. No guesswork. The catalog also includes the tie rod and guide bar on page 7, which ties into the steering system.

Hydraulic System Components: Pumps and Valves

The bucket and boom hydraulic pump is covered separately for G.M. (page 96) and Waukesha (pages 94, 96, 97). The control valve assembly is on page 109, and the control valve itself on page 111. The reservoir breather cap is page 105. If your boom cylinder is leaking, the cylinder assembly is page 106; the bucket cylinder assembly is page 107. Every component has a part number. I’ve used this catalog to source a direct replacement for a boom pipe (page 7) without having to pull the entire assembly off the machine.

Brake System: From Master Cylinder to Wheel Cylinder

Brake controls and floorboard are on page 69. The master cylinder is listed on the same page. Front brake assembly is page 70; rear brake assembly is page 71. Wheel cylinders are included on both those pages. The parking brake controls are on page 75, and the brake vacuum lines run across pages 73 and 74. If your machine has a G.M. engine, the vacuum pump is on page 5; Waukesha Diesel on page 4. The booster steering assembly also ties into the brake vacuum system—G.M. on pages 85 and 87, Waukesha on pages 83, 85, 87.

Engine-Related Parts: Belts, Filters, and Carburetors

Fan belts for Waukesha Gas are on page 1; Waukesha Diesel on page 3. Air cleaner and muffler configurations vary: Waukesha Gas on page 14, Waukesha Diesel on pages 15-16, G.M. on page 17. Carburetor is page 2 (Waukesha Gas). Engine lube filter cartridge for Waukesha Gas is page 2. Fuel filter cartridges—primary and secondary—for Waukesha Diesel are on pages 22 and 23. The accelerator pedal and linkage pages (18, 19, 20) depend on engine type. Page 18 covers Waukesha Gas-Diesel linkage; page 19 is Waukesha Diesel; page 20 is G.M. That master cylinder part number is on page 69.

Transmission and Torque Converter Parts

The transmission control cover assembly is on page 33, and the transmission controls are page 35. Torque converter pages are 39-47 (multiple views for the converter and its housing). Converter charging pump is pages 48-49. Cartridge kits for transmission and torque converter are on pages 51, 53, and 55. If you’re dropping the transmission pan to replace filter cartridges, you’ll want those pages for the correct kit number. The transmission also shares components with the torque converter, so the index cross-references everything.

Why This 164-Page OEM Manual Beats Aftermarket Copies

Clark Equipment Company printed this catalog with machine serial number ranges: 125A Waukesha from 12123 through 14130, and 125A G.M. from 13337 through 13556 and 16123 through 16417. Aftermarket parts lists often miss these serial splits, leading to wrong parts for pre-update machines. This is the original document—no reprint, no rescan of a scan. The images are crisp, the part numbers are readable, and the index (starting on page 1) is complete. You can also verify part numbers against the Automotive Industry Overview of part numbering conventions. Understanding your engine type—whether G.M. or Waukesha—is critical; read more about the Internal Combustion Engine basics if needed.

Frequently Asked Questions

Does this parts catalog include service procedures like torque specs?

No, this is a parts catalog, not a service manual. You’ll need the separate service manual for repair procedures and torque values.

How do I know which part number fits my machine?

Look up your machine serial number in the front of the catalog against the range listed for your engine type (Waukesha or G.M.). Then find the section for that system—for example, if you need a brake master cylinder, go to page 69. The exploded diagram shows the part number and description. Cross-reference with the index starting on page 1. If you have a G.M. engine, the booster steering assembly is on pages 85 and 87; for Waukesha, pages 83, 85, 87. Always use the serial number when ordering.
