This is a new, genuine Kubota injection pump assembly, part number 16032-51013, for Kubota’s 3-cylinder 05 Series diesels: the D905, D1005, D1105 and D1305. Kubota dealer parts catalogs list it on BX2660, BX2670 and BX2680 sub-compact tractors, B2301, B2320, B2401, B26, B2601, B2620, B2630, B2650, B2920 and LX2610 tractors, RTV1100, RTV-X1100C, RTV-X1120D and RTV-X1140 utility vehicles, F2680E, F2690 and F3080 front mowers and ZD326, ZD331 and ZD1211 zero-turn mowers. It replaces 16032-51010, so it also covers older machines first built with that number, such as the BX2200D, BX22D, BX23D, B7500, B7510, B7610, KX41-2, KX61-2 and U25S.

The same pump serves all four engine sizes. The BX2680 runs the D1005, the B2601 the D1105, the B2920 and LX2610 the D1305, and the older BX2200 the D905. Kubota also has a look-alike pump, 16030-51013, which its industrial engine parts lists give for the D905, D1005, D1105 and D1305. Kubota’s tractor, mower, RTV and excavator catalogs call for 16032-51013, so match the number on your old pump. 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.

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.
