Yale MS12, MS10 1999 Parts Catalog

Open the box of a used Yale MS10 or MS12 forklift, and you’ll find a stack of parts that may or may not belong. Without a factory parts catalog, you’re guessing at which hydraulic cylinder seal goes where, or whether that magnetic brake armature is the right one. I’ve seen techs order the wrong traction motor bearing three times because they trusted an aftermarket parts list. The Yale MS12, MS10 1999 Parts Catalog stops that. It’s the OEM document, 48 pages, published in 1999 with part number 272354300. Every exploded view, every reference number, every fastener callout comes straight from Yale’s engineering department. No generic diagrams, no “equivalent” nonsense.

What’s Inside the Yale MS10/MS12 Parts Catalog

Flip to the table of contents and you’ll see sections that match the actual machine: COVERS/ADESIVE LABELS, SUPPORTS AND CASTER WHEELS, LOAD WHEELS, TRACTION UNIT, TRACTION MOTOR, MAGNETIC BRAKE, DRAWBAR CONTROL BOX, DRAWBAR CONTROL BOX OPT, DISTRIBUTOR, HYDRAULIC SYSTEM, MAST 1 STAGE FFL, MAST 2 STAGE Hi-Vi, MAST 3 STAGE Hi-Vi, HYDRAULIC CYLINDER, FORKS, WIRE NET, WIRING DIAGRAM, SHEATH DIAGRAM, ELECTRICAL DIAGRAM, HYDRAULIC DIAGRAM, BATTERY CHARGER, CONSOLE ADAPTER, CONTACTS,CONNECTORS,TOOLS, and a NUMERICAL INDEX. That covers the whole machine – from the mast to the wiring harness. Page 1 shows the multi-language title block and the part number format. Page 48 holds the numerical index, so you can cross-reference any part number fast.

Why Use the Factory Parts Catalog Instead of Aftermarket

Aftermarket parts catalogs are compiled from multiple sources, often with mismatched part numbers. I’ve seen a “compatible” brake assembly listed for the MS12 that actually came from a different Yale model. The Yale factory catalog gives you the exact OEM part number, including supersession history if it exists. The exploded drawings show how the parts fit together – critical when you’re rebuilding the Hydraulic Cylinder or replacing the Magnetic Brake armature. You don’t need to guess which shim goes where. The diagram tells you. And the Wiring Diagram, Sheath Diagram, and Electrical Diagram sections let you trace every wire and connector. For a Automotive Industry Overview, you’ll recognize the same standards used in heavy equipment. But this catalog is specific to the MS10 and MS12.

How to Use This Catalog on the Bench

You’ve got the machine torn down. You need a part number for the traction motor brush holder. Open the catalog to the TRACTION MOTOR section. Each assembly is shown as an exploded view with numbered callouts. Next to the diagram is a list with the part number, description, and quantity. Write down the number, then flip to the NUMERICAL INDEX on page 48 to double-check it. That index lists every part number in the catalog and the page where it appears. Cross-reference it with the diagram. If you’re ordering from a dealer, give them that part number. They’ll know it’s correct because it’s the same number stamped on the original part. I’ve used this method for years – it saves you from ordering a part that looks right but isn’t.

3 Systems You Can Successfully Rebuild with This Manual

Hydraulic System – The HYDRAULIC SYSTEM and HYDRAULIC CYLINDER sections cover the pump, valves, cylinders, and hoses. The HYDRAULIC DIAGRAM shows the flow paths. You can identify every seal and o-ring by part number.
Magnetic Brake – The MAGNETIC BRAKE section shows the coil, armature, and brake pads. The exploded view makes reassembly straightforward.
Electrical System – The WIRING DIAGRAM, ELECTRICAL DIAGRAM, and BATTERY CHARGER sections cover the entire electrical system, including the CONSOLE ADAPTER and CONTACTS,CONNECTORS,TOOLS. You’ll trace the harness from the DRAWBAR CONTROL BOX to the traction motor.

Not a generic diagram. Factory-correct. That’s the difference.

Electrical and Wiring: What This Catalog Includes

The WIRING DIAGRAM, SHEATH DIAGRAM, and ELECTRICAL DIAGRAM sections are separate. The wiring diagram shows the individual wires and connections. The sheath diagram shows the routing and protective conduits. The electrical diagram is the schematic – you need all three to diagnose a short or replace a harness. The BATTERY CHARGER section covers the charger components. The CONSOLE ADAPTER and CONTACTS,CONNECTORS,TOOLS sections list every connector and terminal. If you’re rebuilding a Yale MS10 or MS12 after a battery acid spill, this catalog is your roadmap. You can find every wire, every connector, every grommet.

Frequently Asked Questions

Does this catalog include service procedures or torque specs?

No. This is a Parts Catalog, not a service manual. It contains exploded views, part numbers, and diagrams. You need the corresponding service manual for torque values and repair procedures.

Will this work for the MS10E or MS12-15S models?

This catalog covers the MS10 and MS12 base models from 1999. For the MS10E or MS12-15S, check the Yale MS12-15S Parts Catalog or Yale MS10 MS12 MS10E 2006 Parts Catalog.

How do I find a part number for the hydraulic cylinder seals?

Open the HYDRAULIC CYLINDER section. The exploded view shows each seal with a callout number. The parts list next to the diagram gives the part number. Cross-reference it in the NUMERICAL INDEX on page 48 to confirm the page.

Can I use this catalog to order parts online?

Yes. The part numbers are OEM Yale numbers. Verify with your dealer that they still supersede, but the catalog is the original source. For related models, see Yale MS10 MS12 Parts Catalog.

You’ve got the machine on the shop floor. You need the right part.
