Michigan 125B 1989 Parts Catalog

Ever ordered a hydraulic pump seal based on an aftermarket website, only to find it doesn’t fit because the part was superseded twice? I’ve seen that mistake cost a full Saturday and a rental bill. For a machine like the Michigan 125B articulated tractor shovel, you need the factory part number, not a community forum guess. That’s what this Parts Catalog from 1989 is for. It’s the original Clark Equipment documentation – 632 pages of part numbers, exploded views, and serial number breaks that tell you exactly which piece goes where. No fluff, no reprints, no third-party interpretation.

When you’re digging through a parts bin at a salvage yard or calling a dealer who wants your machine’s serial number, having the right reference saves time and money. This catalog covers the Cummins and G.M. engine variants noted on page 2, and it includes the serial number record sheet so you can track your own machine. Don’t trust a third-party parts list that was scanned from a copy of a copy. Start with the original.

632 Pages of Factory Part Numbers

That’s 632 pages total – each one printed from the same plates Clark used at the factory. Inside you’ll find exploded diagrams for the drivetrain, hydraulics, steering, brakes, and the entire bucket linkage. Every part is listed with its original part number, description, and quantity required. Need a brake shoe for the rear axle? The catalog will show you the exact pad, the spring kit, and the retaining hardware – all with the factory numbers. There’s no need to cross-reference a third-party database that might use a universal number that doesn’t match your machine’s build date.

What This Parts Catalog Actually Covers

This isn’t a service manual – it’s a parts identification tool. But if you’re rebuilding the hydraulic control valve on a Michigan 125B, you need the O-ring kit number before you start tearing it down. The catalog includes the complete machine breakdown: engine, torque converter, transmission, axles, frame, bucket, and electrical. Each section has an exploded view with callouts that correspond to a parts list on the facing page. The warranty information on page 1 and the improvement notes on page 3 remind you that Clark reserved the right to change design – so the part number you see may not be the latest. Always verify your machine’s serial number against the chart in the catalog.

Why Aftermarket Catalogs Will Cost You Money

I’ve had guys bring me a seal that looked right but was 0.010” too thick – because the aftermarket catalog gave them a generic fitment. With this OEM Parts Catalog, you get the exact part number that Clark stamped on the original drawing. No guesswork, no returns, no downtime waiting for the correct part to arrive. The difference between a $12 O-ring and a $120 pump replacement is using the right catalog from the start. This is the same document a dealer parts counter used in 1989 – it’s not been re-keyed or reinterpreted. You get the raw data.

3 Reasons to Trust OEM Documentation

• Original part numbers – not aftermarket renumbering schemes.
• Serial number breaks – know exactly which parts fit your machine.
• Factory illustrations – drawn from the actual engineering drawings, not traced from a photo.

Related manuals you might need: Michigan 125B Articulated Tractor Shovel Parts Manual for the base machine, Michigan 125B Tractor Shovel Parts Manual Supplement for late-model updates, and VOLVO BM 125C Wheel Loader Parts Catalog if you’re working on the later variant.

Get the Right Part, Not a Guess

Stop wasting time on parts that almost fit. This Parts Catalog gives you the factory numbers straight from the 1989 Clark Engineering Department. Whether you’re ordering from a dealer, searching eBay, or hitting up a salvage yard, you can hand them a part number and be sure it’s correct. The 632 pages include everything from the alternator bracket bolts to the bucket tooth adapters. No more “I think it’s this one” – you’ll know.

Does this catalog include exploded views?

Yes. Each major assembly has an exploded diagram with numbered callouts. The parts list below each view gives the OEM part number, description, and quantity. You can see exactly how the hydraulic spool valve comes apart and what seals you need to order.

What about updated part numbers after 1989?

This catalog includes the part numbers as of 1989. Clark issued supplements for later changes – that’s why we also carry the Michigan 125B Tractor Shovel Parts Manual Supplement. If your machine was built after 1989, you’ll want both. Check your serial number plate against the catalog’s serial number break table.

Can I use this for a 1988 model?

Possibly. The 125B was produced for several years. The catalog covers machines with Cummins and G.M. engines – verify your serial number against the range listed on page 2. If your serial falls within the listed range, the parts are correct. If not, you may need a different revision.

How do I identify my machine serial number?

Look on the frame rail near the steering column or on the right side of the engine compartment. The number is stamped into a metal plate. Record it on the form inside the catalog – page 3 shows the template. That serial number is your key to matching parts.

You’ve got the machine. You’ve got the tools. Now get the right numbers. Access the Factory Manual and start ordering the correct parts for your Michigan 125B.
