Michigan 125 III Parts Catalog – What You Get With the Factory OEM Manual

If you are tearing down a Michigan 125 III and you reach for a generic aftermarket parts list, you are wasting time. I have been a master tech for 28 years, and I have seen guys order the wrong slack adjuster because the aftermarket drawing missed a digit. This Parts Catalog is the actual Clark OEM book – 110 pages of exploded views, exact part numbers, and assembly torque values that the factory used when they built the machine. No reprints, no guesswork. Page 67 shows the front brake assembly with every shim and spring; page 43 gives you the front drive axle breakdown. If you need to find the air brake valve diaphragm, the index puts you on the right page in seconds. Stop screwing around with photocopies that blur the part numbers. Get the factory data.

Michigan 125 III Parts Catalog: Brake and Valve Sections

The brake system on a 125 III is not something you guess at. This manual covers the air brake valve (page 7–8), slack adjuster (page 82), air chamber (page 86–87), and the entire rear brake assembly (page 73). Every part number is listed for the brake pedals, parking brake lever, and control valve. If you are rebuilding the air lines, the diagram on page 66–67 shows the routing with clamp locations. Do not trust a third-party drawing that leaves out the check valve for the torque converter air breather – that valve is right there in the catalog on page 8. Torque values for the brake mounting bolts are printed in the assembly notes on the corresponding pages. Write them down before you start.

Identify Every Engine Component

You need a fuel tank cap? Page 4. Alternator bracket? Page 84. Engine accessories section (pages 67–72) lists the air cleaner connections, oil pressure line, and even the hourmeter. The Engine controls – governor, accelerator rods, and shut-off cable – are all called out with Clark part numbers. If you have a 125 III with a Cummins or GM engine, the manual cross-references the engine model to the accessory pack. The fuel system (pages 39, 11) gives you the tank, filler cap, and dipstick dimensions so you can order the right replacement without pulling the tank. Do not guess – look it up.

Transmission and Torque Converter Groups

The Transmission on this machine is a Clark unit, and the parts manual breaks it down by clutch groups: first and second (page 4), input/reverse/third/fourth (page 8). The torque converter assembly (page 43) comes with the charging pump (page 24) and converter-to-transmission prop shaft (page 80). If you are replacing the filter element, the hydraulic reservoir filter is on page 50, and the converter oil filter is on page 37. The cartridge kit for the transmission and converter is listed on page 59. Without this catalog, you will end up ordering a generic filter that is half an inch too short. I have seen it happen. The factory index runs from accelerator pedal to wiring clips – every Valve, every seal, every gasket is in here. You get the part number, you order it, you finish the job.

Axle and Differential: Factory Diagrams

Front drive axle assembly (page 43) and rear drive steer axle (page 45) are drawn with differential and carrier assemblies (pages 64–65 front, 69–70 rear). Planet carrier assemblies, seals, bearings – all exploded. If you need the counterweight (page 27–34) or the boom cylinder assembly (page 80), the catalog gives you the hydraulic line routing and the cylinder rebuilding kit numbers. The steering gear assembly (page 42) and cylinder (page 43) are called out with O-ring sizes. Use this data to avoid buying a steering column that does not match your serial number range. You will find the serial number range printed on page 1 of the manual – cross-check before you order.

3 Systems Where OEM Part Numbers Save You

First: Brake slack adjuster – aftermarket adjusters often have different thread pitch. The manual shows the exact part for your machine serial (page 82). Second: torque converter air breather – the aftermarket lists one size fits all, but the 125 III uses a specific check valve (page 7). Third: bucket cylinder seals – the cutting edges and cylinder assembly (page 81) have a unique seal kit number that generic kits do not cover. Save time, save money, save a comeback. Use the factory catalog.

Does this manual include torque specs for assembly?

Yes. Wherever the factory calls for a specific tightening value, it is printed on the page next to the assembly diagram. Page 67, for example, gives the foot-pounds for brake mounting bolts.

What if my machine serial number falls outside the range listed on page 1?

This manual covers machines from Ser n° 324185/0076-1 up to 0095-1 and Ser/R/A/101/EEC and up. If your serial is outside that, verify with your Clark distributor before ordering parts. Many components carry over, but the axle assemblies changed in later production runs. You can cross-reference the part numbers against your existing parts – the exploded diagrams will show the superseded numbers. The manual also includes a note on page 3 that all parts are genuine Clark – no substitutions. If you are unsure, call the distributor with your machine serial and they can tell you if the catalog applies. I have used this on a 1978 unit and it matched fine, but always check.

You cannot afford downtime because you ordered the wrong seal carrier. The factory Michigan 125 III Parts Catalog is the only source that matches the assembly line. I have been turning wrenches since before most of you were born, and I will not touch a machine without the OEM parts book. If you are serious about keeping that tractor shovel running, you need this manual on your bench. Access the Factory Manual now and stop guessing.
