Kubota Oil Pump 15471-35012 — Fits D1403 D1803 V1502 F2803 S2600

Good catch — the title and fitment list don't fully match. The OEM 15471-35012 / 15471-35013 oil pump is the same casting used across many Kubota indirect-injection engines including the D-series and the V1502 / F-series listed here. It commonly cross-references to V2203 applications as well, but if your engine is a V2203 IDI or V2203 DI, verify the OEM number stamped on your old pump matches 15471-35012 or 15471-35013 before ordering. Call (818) 261-3896 if you want help confirming.

Best test: run a manual mechanical oil pressure gauge in place of the factory sender. If pressure at hot idle is below Kubota's spec but you have no bearing knock, the pump is suspect. If you have bearing knock AND low pressure, the bearings are letting oil through and the pump may be fine — replacing the pump won't fix that. Drop the pan and Plastigage the bearings before replacing the pump.

This pump is sold as the pump assembly only. Reuse your existing pickup tube and pressure relief components if they're in good condition. If you find debris or metal in the pump or pickup screen, replace the screen as well. Always replace the oil and filter when installing a new pump — debris from the old pump will be in the system.
