Yale MC10, MC12, MC15 Parts Catalog – OEM Factory Documentation

You’re turning wrenches on a Yale MC10, MC12, or MC15 and you need a part number – not a guess. Aftermarket parts catalogs have a bad habit of swapping seals, bearings, or hose assemblies across years, and that gets you a truck that won’t lift rated load or a leak that shows up on the shift report. This Yale MC10, MC12, MC15 Parts Catalog is the factory original – 68 pages of exploded views, part numbers, and sheet indexes that match exactly what Yale shipped. No reprints, no third-party interpretation. If you’ve ever ordered a mast roller kit only to find the pin diameter is 2 mm off, you already understand why this matters.

Part Sheet Index – How to Navigate the 68 Pages

Before you flip to the hydraulic section, you need to understand the layout. The first two pages (pages 2–3 of the PDF) give you the Part sheet index printed in five languages – English, Italian, French, German, Spanish. That’s followed by the legend of symbols and “How to use the handbook.” Pay attention to the symbol legend: it explains whether a part is a service kit, a wear item, or a non-reusable fastener. Page 4 details the frame for pedestrian drive (part sheet 1) and page 5 covers the ride-on drive frame (part sheet 1.1). The numbering is consistent: each sheet covers a specific subsystem. You don’t have to flip through the whole 68 pages to find the lift cylinder for a triplex mast – the index points you to part sheet 9.1.

Frame and Mast Coverage – Pedestrian vs. Ride-On

Two different frame assemblies exist for the MC10–15 series: pedestrian drive (part sheet 1) and ride-on drive (part sheet 1.1). The catalog shows every weldment, bumper, and mounting bracket with individual callouts. Masts are broken into three variants – duplex (part sheet 2), triplex (2.1), and triplex G.A.L. (2.2). G.A.L. stands for “Guida A Larga” – wide guide? No matter. What matters is that the parts are different: the triplex G.A.L. uses a different lifting cylinder and backing plate. If you’re rebuilding a mast, you need the correct sheet. The Fem carriage (part sheet 3) and drawbars for pedestrian and ride-on (sheets 4 and 4.1) are also broken out separately. You can’t mix them.

Hydraulic System and Lifting Units – Part Numbers You Can Trust

Hydraulic system (part sheet 7) covers the pump, control valve, hoses, and fittings. The lifting unit sheets are specific to mast type: duplex (sheet 8), triplex (8.1), triplex G.A.L. (8.2). Lifting cylinders are on sheets 9, 9.1, and 9.2. There’s also an auxiliary cylinder for the triplex G.A.L. (sheet 9.3). Each sheet includes the manufacturer’s part number, quantity, and sometimes a note about service kits. Need the charge pressure? Page 73? No – this is a parts catalog, not a service manual. But the part numbers for the hydraulic pump seal kit are right there. Pair this catalog with a service manual like the Eaton Yale & Towne 1700 1969 Service Manual – OEM Factory Data and you’ll have the full picture.

Why OEM Parts Catalog Beats Aftermarket Copies

I’ve seen aftermarket catalogs that list one part number for the MC10, MC12, and MC15 steering column, but the ride-on version (part sheet 5) uses a different steering column than the pedestrian drawbar. The OEM catalog has a separate sheet for the steering column ride-on (sheet 5) and drawbar pedestrian (sheet 4) because the parts are physically different. Aftermarket producers often merge them, and you end up ordering the wrong threaded rod. This catalog was printed by Yale Europe – you can see the trademark on page 1. It’s the same document the dealer parts counter uses. If you want to cross-reference with other Yale models, take a look at Yale OS 030 BC SS 030 BC 1997 Parts Catalog OEM or Yale MP, MPB 040 AC 1997 Parts Catalog Factory OEM – also factory documents.

Who Needs This Catalog – And Who Doesn’t

If you’re a home-garage guy who bought a used MC10 at auction and needs to identify which bearings go in the load wheels (part sheet 6), this catalog is for you. The load wheel sheet lists the wheel assembly, tire, and spacer with part numbers. You can order exactly what you need instead of pulling a bearing and measuring it. It also saves you from ordering a complete wheel when you only need a tire. But if you’re looking for torque specs or service procedures – this is not that document. It’s a parts catalog. You need the service manual separately. The Automotive Industry Overview has plenty of general info, but it won’t help you find the part number for a MC15 triplex G.A.L. lifting cylinder seal. For that, you need this catalog.

Does this catalog include part numbers for the steering column on the ride-on model?

Yes. Steering column is covered on part sheet 5. The catalog shows the column assembly, steering wheel, and all mounting hardware with individual part numbers. If you need the pedestrian drawbar, that’s sheet 4 – don’t mix them up.

Can I use this catalog to order parts for a MC15 triplex G.A.L. mast?

You can, but it’s critical to verify the serial number range of your truck against the catalog – Yale made running changes to the triplex G.A.L. lifting cylinder (sheet 9.2) and auxiliary cylinder (sheet 9.3). The catalog does not list supersessions or engineering changes, so if your truck is a late production model, cross-reference with your dealer. For general mast repair, the mast sheets (2.2) and lifting unit (8.2) are complete. The Automotive Industry Overview won’t help here – you need the actual part number from the sheet.

Don’t waste a week trying to match a part by eyeballing it. This OEM parts catalog cuts the R&D out of ordering. Every sheet is a direct copy of what Yale put together. Access the Factory Manual and keep it on your bench – you’ll use it every time a hose leaks or a roller wears out.
