Kubota Engine Parts

Parts Compatibility for Kubota Industrial Engines

Kubota groups its industrial engines into displacement series that share many internal components within a series, even across different model designations. The 05 Series is the largest of those families and includes the 3 cylinder D902, D1105, D1305, and D1503 alongside the 4 cylinder V1505, V2003, V2203, and V2403. Engines in the same series often share the same air filter, the same engine oil filter, and the same primary fuel filter cartridge, which is why a single replacement filter can list dozens of engine models in its compatibility data. The 03 Series (D722, D905, D1005) sits below the 05 Series in displacement and is common in compact mowers, generators, and small skid steers. The 07 Series (D1703, D1803) and 09 Series (V3300, V3307, V3600, V3800) cover the larger horsepower bands used in mid size tractors, telehandlers, and full size wheel loaders.

Tier 4 Final, EU Stage V, and earlier Tier 3 / Stage IIIA emissions versions of the same base engine often use different fuel system, EGR, and aftertreatment components, but they typically share the same lube oil filter and air filter. When ordering replacement parts, the engine serial number plate on the rocker cover or block side carries the full engine model designation (for example V2403-CR-TE5 or D1105-E4B), and the suffix after the base model identifies the specific emissions tier. The OEM part number printed on your existing filter is the most reliable cross reference, since the same Kubota base engine can ship with different filter housings depending on which equipment it was installed in.

Common Replacement Parts for Kubota Engines

Routine maintenance filters are the highest demand replacement category for Kubota engines. Engine oil filter cross references include Kubota HH150-32094, 15208-43170, HH1J0-32430, W21ESO1600, 16271-32090, 16271-32091, 1521332091, 70000-14672, and 70000-14653, which collectively cover most 03 and 05 Series engines used in compact tractors, mini excavators, skid steers, and front mowers. Primary fuel filter cartridges include RB101-51281, RB101-51282, RD819-51280, 12581-43011, 12581-43012, 12581-43013, and 1542563013, with water separator versions HHV00-51920, 1K011-43060, and 6A320-59930 used on later Tier 4 engines.

For air filtration, common outer air filter cross references include 1G379-11210, 7000014656, 7000014556, 7000012850, 1947811080, 1923787481, 1552111080, 15401-11080, 1522111080, 1510411080, and 1450111081. These cover both finned and radial seal canister styles. Gaskets, thermostats (15321-73010), oil pressure switches (15531-39010), pulleys (1C010-64110, 1C010-74250, 1K011-74250), studs, and oil gauge plugs (1G513-36550) round out the engine page inventory. The CR-TE5 common rail variants of the V1505, V2403, and V2607 use different fuel injection components than the older mechanically governed E2B / E3B versions, so always verify your engine model designation against the part number listing on each product page.
