This is a new, genuine Kubota injection pump assembly, part number 17159-51012, for the 4-cylinder Kubota V2203. Kubota engine parts catalogs list this pump series for the V2203. It is not the pump on every V2203: Kubota’s parts lists show 1G762-51012 on the V2203-E2B industrial engine and 1G916-51013 on the V2203-M-E3B.

We found no Kubota tractor or excavator parts list that calls for this pump, so order it by the number on your old pump and the engine serial number, not by engine model alone. Replace the pump when it leaks fuel, the control rack sticks, or the plungers and barrels are worn or rusted after dirty or wet fuel got through. It comes as a complete pump assembly.

Specifications

Fits / Applications

• Kubota V2203 engines whose parts list or old pump calls for 17159-51012
• Not the pump for the V2203-E2B (1G762-51012) or the V2203-M-E3B (1G916-51013)

Kubota sets injection timing on this style of pump with shims under the pump mounting flange. Keep the old shim stack, fit it under the new pump, then check timing to the Kubota workshop manual spec for your engine. When you fit the pump, use the stop lever to line up the governor fork with the pump’s control rack pin; a missed pin can damage the fork. Find out why the old pump failed, then flush the tank and lines and fit new filters before start-up.

Frequently Asked Questions

Will the 17159-51012 fit any Kubota V2203?

No. Kubota built the V2203 with several injection pumps: its parts lists show 1G762-51012 on the V2203-E2B and 1G916-51013 on the V2203-M-E3B. Order 17159-51012 only when your old pump or your engine’s parts list calls for it.

My old pump is marked 17159-51010. Is this the right replacement?

Kubota dealers show 17159-51010 as an older, superseded number in the same series, but they do not name the new number. Call 530-668-0818 with your engine serial number and we will confirm the current pump before you order.

Is this pump new or remanufactured?

New, genuine Kubota. It comes as a complete 4-cylinder pump assembly.

What do you need from me to confirm the fit?

The engine model and spec from the engine label, the engine serial number and the number on your old pump. With those we can check Kubota’s parts list for your exact engine.
