Forklift Water Pumps

Coolant that leaks from the pump housing or an engine that runs hot after a belt change often points to the water pump, and about 310 listings here are for exactly that. Most are complete pumps for forklift engines, and others are gaskets, repair kits and the belts and hoses that go with them.

Forklift Water Pump Types

The common listing is a plain pump with a make and number, such as "FOR Komatsu 21010-FU40J, Water Pump" or "FOR HYSTER FORKLIFT WATER PUMP 1498507". In all, 48 listings are pumps sold with a gasket, 16 of them worded "Includes Gasket" or "Gasket inc." ("For Caterpillar 0973128, WATER PUMP (Includes Gasket), FORKLIFT"), and 15 add a pulley, 14 of those with a gasket too, like "for Continental F162K36519, 162K36519- NEW Water Pump with Pulley & Gasket". Pulleys sold alone are on the forklift pulleys page.

Not every listing is a whole pump. Ten or so are repair kits, such as "FOR Yale 901282811, WATER PUMP REPAIR KIT, Forklift" and "For Caterpillar 4W7683, Repair Kit, For Water Pump". Another 10 are gaskets sold on their own ("FOR GENIE 33964GT, 33964, ENG - WATER PUMP GASKET"), plus 11 belts and a hose. For gaskets generally, see forklift seals and gaskets. About 65 listings say "new", which helps when two similar pumps sit side by side.

Water Pumps by Truck Make

Caterpillar has the most, about 45 listings, followed by Toyota at about 40. Hyster water pumps come to about 35, Yale water pumps to about 30, and Toyota water pumps have their own page too. After those are Clark at 23, Genie at 22 and Nissan at about 20, then Mitsubishi, TCM and Komatsu. Perkins appears in 10 pump listings, and Bobcat has 7 pumps, 5 of them labeled skid steer. To see everything for one make, go to Clark, Nissan or Genie parts.

Matching a Water Pump to the Truck

Search the number on the old pump first. Toyota numbers are dashed and often end in -71, such as 16120-78052-71, and about 30 listings here follow that pattern. Most Nissan and Komatsu pumps (25 of the 31 listings naming either) start with 21010, as in 21010-20H25 and 21010-FU425, and 11 of the 12 TCM pumps carry the same number with an N- in front. Caterpillar pumps use shorter codes like 9Y5969 or longer ones like 1003038, and Clark ones run six or seven digits (995910, 4327614).

The truck model sometimes appears too. Two Toyota listings name the 40-2FG25, and a Hyster listing names the 11Z-1Z/2Z motor. Some also name the engine builder, with Continental in about 7 listings. When coolant temperature is the real worry, the thermostats, radiators and cooling fans pages cover the rest of the circuit, and all four sit under forklift radiator and exhaust parts.

Water Pump FAQ

Are these pumps made by the truck maker?

Most are aftermarket pumps made to suit the make named in the title, as in "Aftermarket For Caterpillar Forklift Water Pump with Gasket PN 1003038". If you want a genuine OEM pump, call (708) 507-0707 and ask what is available.

Can I buy a gasket without the pump?

Yes. Look for "water pump gasket" in the title, which turns up for Toyota and Genie, among others.
