Clark Equipment 125 III A Parts Catalog – OEM Factory Manual

You’re working on a Clark Equipment 125 III A articulated tractor shovel, and the job stalls because you can’t find the right part number. Maybe it’s a Brake pedal assembly, a steering Valve, or the rear drive planet carrier. You waste billable hours flipping through aftermarket compilations that omit half the exploded views. That stops here. This is the genuine OEM Parts Catalog – 98 pages of factory-level indexing, straight from Clark Equipment Company’s Construction Machinery Division. No reprints, no third-party guesswork. If you need the parking brake lever group (page 49) or the foot valve assembly (page 54), this manual puts the exact reference in your hands.

Most aftermarket parts books lift a few diagrams and call it done. They leave out the hydraulic pump breakdowns, the torque converter charge pump specs, or the wiring harness routing. On a machine this size, that missing detail costs you downtime and broken hardware. This catalog covers every numbered assembly – from the transmission control cover (page 25) to the tail light wiring harness (page 81). You get the original part numbers, the correct quantities, and the assembly sequences that match what Clark Engineering originally laid out.

Brake Assemblies and Valve Systems: Factory Indexed

You don’t have time to hunt through generic sections. The Brake group is laid out clear: parking brake lever assembly (page 49), pedal assembly (page 54), rear brake assembly (page 43), and air brake valve assembly (page 54). Valve systems get the same treatment – steering pressure relief valve (page 62), downstream pressure regulating valve (page 31), transmission de-clutch valve (page 51), and control valve assembly (page 71). Each page shows the exploded view, the part callouts, and the reference numbers for ordering. For a job like rebuilding the rear brake pack, you flip to page 43 and see every seal, piston, and spring listed. No guesswork.

Transmission and Hydraulic System Coverage

The transmission section runs from pages 17 through 27. You get the torque converter assembly (pages 29-30), the case and internal tubing (page 21), and the oil filter setup (page 27). The hydraulic pump breakdowns – converter charging pump (page 30), main hydraulic pump (page 69), steering hydraulic pump (page 59) – are all there. For a machine that sees 10,000 hours, the ability to cross-reference a pump seal kit or a control valve spool against the factory diagram saves you a return trip to the parts counter.

Wiring Diagrams: Engine and Cockpit

Electrical gremlins on a 125 III A can shut you down fast. This catalog includes the wiring diagram for the engine (page 83) and the cockpit (page 82). Harness layouts for the cab (page 79), front lights (page 81), flood lights (page 81), and instrument panel (page 75) are all mapped. If you’re chasing a short in the tail light circuit, you get the wire colors and connector locations straight from the factory print. No aftermarket artist redraws.

Who Actually Needs This Manual

If you own a Clark Equipment 125 III A – whether it’s a 1970s machine or a later unit with serial numbers 7AFC101 through 7AFC999 – this is your parts bible. Home garage enthusiasts who do their own heavy equipment maintenance will find the exploded views essential for disassembly without breaking components. Professional mechanics working on construction sites can use the 98-page bound format (PDF, but printed to match the original) to hand a junior tech a page and say “find these parts.” Workshop owners with a fleet of Michigan loaders reduce stocking errors when they spec from factory numbers instead of aftermarket cross-references.

3 Reasons to Choose OEM Documentation

First, the Parts Catalog is the original document released by Clark Equipment Company – not a third-party scan with missing pages. Second, every torque spec, part number, and assembly orientation matches the factory’s bill of materials. Third, the index is organized by functional groups (brake, steering, transmission, electrical) so you don’t waste time guessing which section covers the steering drag link (page 61) or the propeller shaft assemblies (page 47). Aftermarket catalogs rearrange content arbitrarily and often mislabel hydraulic components. This is factory-correct.

FAQ

Does this manual cover the fuel system?

Yes – the fuel tank (page 13), tail pipe and connections (page 10), and the radiator and connections (page 9) are included. The fuel system is not a separate section but the parts for the engine support and connections are listed under the R section and engine group.

Are tire data and wheel specs included?

Page 73.

What about the transmission de-clutch valve assembly – is that listed?

Yes, page 51. You get the full breakdown including the valve body, spool, springs, and mounting hardware. The transmission control cover assembly is on page 25, and the selector valve assembly is on page 17. Everything is cross‑referenced to the original part numbers.

Can I use this to order parts from a dealer?

You can hand them the Clark part number from the page. Dealers rely on those numbers – generic aftermarket numbers cause returns. This catalog gets you the right seal kit for the steering pressure relief valve (page 62) or the complete rear drive planet carrier assembly (page 53).

When you’re elbow-deep in a transmission rebuild on a Saturday, the last thing you want is a parts catalog that skips pages or lists wrong numbers. Every page in this OEM Clark Equipment 125 III A Parts Catalog was printed from the same plates used by Clark’s own service departments. It’s 98 pages of factory information, from the parking brake lever (page 49) to the wiring harness clips (page 80). Access the Factory Manual and keep it on your shop tablet or printed binder.
