Komatsu Forklift Master Cylinders

Most master cylinder listings for Komatsu trucks come down to matching a number, and this page holds 29 of them. Every listing says Komatsu and master cylinder in its wording, and several give two or three numbers side by side. Compare the one stamped on your cylinder with the figures below.

Nothing here comes from Komatsu. The listings are aftermarket replacements made to fit Komatsu trucks, and the Komatsu or Allis Chalmers name only tells you what each one replaces. Five of the 29 name both brands, as in "FOR Allis Chalmers / FOR Komatsu FORKLIFT TRUCK MASTER CYLINDER part # 4833142."

Komatsu Forklift Master Cylinder Part Number Styles

Three shapes cover most of the page. The first is the Komatsu code with "-36-" in the middle: 3EB-36-11100, 3EB-36-22700, 3EB-36-51180, 3EA-36-11100, 3EC-36-11211, 3BA-36-21101, 34A-36-11400 and 34C-36-11150. A second pair uses "-10-" instead, 3EB-10-21211 and 3EB-10-31270. The third shape is a plain seven-digit number, such as 4901495, 4949450, 4967822 or 4983933.

A few numbers sit outside those patterns. 307-43-13300 and 358-43-12200 follow a "-43-" pattern of their own, and 3004332160, MY012-8351-00 and 55-801 stand alone. Because the listing's number is the only thing that tells these groups apart, copy it exactly as printed.

Numbers That Appear in More Than One Form

Several cylinders are listed under two spellings. 3EB-36-31280 also appears as 3EB3631280, and 4940552 and 4983933 each have a version with "KO" in front (KO4940552, KO4983933). A search that adds or drops the prefix, or the dashes, will turn up both. 3EB-36-31281, 3EA-36-11100 and 3EA-36-11100A are separate listings that differ only by a digit or a letter at the end, so read the last character.

One listing carries a slash pair: "358-43-12200 / 358-43-12201A." Another, for Komatsu and Allis Chalmers, lists three numbers at once: 4794977, 4769099 and 4713374. If yours is any one of the three, that listing is the one to open.

Push Rods, Brake Wording and Allis Chalmers Listings

Four listings come "with Push Rod," for example "Forklift Master Cylinder with Push Rod for Komatsu 4901495" and the one for 4944181. The number 4901495 appears twice, once with and once without that wording, so check which one you're opening. Two listings say "BRAKE" outright, 4967822 and the new 3EB-36-31281; the others say only master cylinder.

The Allis Chalmers crossover listings are useful if your truck carries that badge. One names the engine as H20 and the model as FG10H-1 beside 34A-36-11400. More Allis Chalmers items are on the Allis Chalmers parts page, which has about 1,050 listings. Three of the 29 listings say "NEW." The H20 engine reference on that listing is the only engine named anywhere on the page, so everywhere else the number is the match.

Komatsu Master Cylinder FAQ

Which number do I search if my cylinder has two?

Try either one. Several listings, such as the 358-43 pair, carry both, so one search can find the listing.

Is there a Komatsu master cylinder listing for an Allis Chalmers truck?

Five listings name both makes. The one for 34A-36-11400 also names the H20 engine and the FG10H-1.
