Yale Forklift Master Cylinders

If the brake pedal on a Yale lift truck has gone soft, the master cylinder is one of the first parts people look at, and this page lists 43 of them. The Yale forklift master cylinder listings here include complete cylinders, repair kits for rebuilding one, and two reservoirs. Two listings carry no number at all, and every other one names a part number, with a few spelling out several.

Cylinders, Repair Kits and Reservoirs

Most of the page is complete cylinders, written as "BRAKE MASTER CYLINDER" or just "MASTER CYLINDER," for example "Yale 580085537, Brake Master Cylinder, Forklift." Six listings are repair kits for a brake master cylinder, such as "FOR Yale 580060995, Repair Kit, For Brake Master Cylinder." One more kit, 900867850, is worded "MASTER CYLINDER KIT" and does not say repair. A kit makes sense when you're rebuilding a cylinder you already have; a complete cylinder is the replacement.

The two reservoirs are listed separately. One is "FOR YALE RESERVOIR - MASTER CYLINDER WITH LEVEL SWITCH 934403300," which comes with a level switch, and the other is "Yale 922559300, Reservoir, For Master Cylinder." Check which style your truck has before choosing.

When a Listing Shows Several Part Numbers

Several master cylinders carry a string of numbers instead of one. "FOR YALE FORKLIFT MASTER CYLINDER 220070731,800087874,800087875" is a good example, and another lists five, starting with 220070406. The strings read as the numbers one cylinder is listed under, so if the number on your old cylinder matches any of them, open that listing first.

Dashed numbers show up as well, such as 0170209-00 and 5010815-00. The second sits beside two plain forms in one title, "YT501081500 501081500," so a search for the digits alone or with the YT prefix both find it. Try each way before deciding the part isn't here.

Parts Shared With Clark, Hyster and Others

A few master cylinder listings name more than one make. Four of the Yale listings also name Hyster and four name Clark. One names Caterpillar, one says CAT and one names Toyota. Number 899499 is the one to look at if you want a cylinder that lists four makes at once. All of them are aftermarket parts, made to fit those trucks rather than by the truck makers.

For a wider look, the Hyster master cylinders and Clark master cylinders pages each hold about 55, and the Toyota master cylinders page about 30. Across every make, forklift master cylinders number about 390.

Finding a Cylinder by Model or Bore

Few titles name a truck, but three do: ERC035AB, GP080LC and GLP080LJ. If yours is one of those, searching the model with "master cylinder" narrows the list quickly. One listing, 915435400, gives a bore size of 3/4 inch in its name instead, which is useful if you've measured the old cylinder.

For a truck that isn't named, work from the number on the cylinder. Four listings also say "NEW" in the title, which helps when two cylinders look the same. The rest of the brand, from transmissions (about 30 listings) to seats and filters, sits on the main Yale forklift parts page.

Yale Forklift Master Cylinder FAQ

Is a reservoir included with the cylinder?

Not unless the listing says so. Reservoirs are separate listings, so add one if yours needs replacing.

Does any listing include a push rod?

One does: "Master Cylinder for Yale with Push Rod 5010815-00." If a title doesn't mention a rod, don't assume one comes with it.

Who do I call if I can't match a number?

Phone (708) 507-0707, Monday to Friday, 8:00 a.m. to 4:00 p.m. Central, and have the truck's model and the cylinder's numbers ready.

Are the repair kits for every cylinder?

No. Each kit has its own Yale number, so compare it to the number on the cylinder you plan to rebuild.
