This is a new, genuine Kubota turbocharger assembly, part number 1J808-17010. It fits the Kubota V2403-CR-TIE4, the intercooled, common-rail 2.4 liter (148.5 cu in) four-cylinder of the 03 Series, the V2403-CR build that runs a DOC and no DPF. IHI builds it for Kubota as an RHF3, and IHI’s numbers for it are VB410266 and F31CAD-S0266B, spec code CK51. Its three-cylinder sister is 1J807-17010 for the D1803-CR.

It is easy to mix up with the other V2403 turbos. 1J802-17010 and 1J803-17012 are IHI turbos for other V2403 builds, and 1J403-17016 is the Mitsubishi turbo for the mechanical V2403-M-T. None of them is this part, so check the tag on the old turbo. A turbo is usually replaced for shaft play with wheel rub, oil at the compressor outlet or in the exhaust, a noisy or seized rotor, or low boost. Check the air filter, the intake hoses, the oil feed and the oil drain before the new one goes on.

Specifications

Fits / Applications

• Kubota V2403-CR-TIE4 four-cylinder common-rail turbo diesel, intercooled, DOC only (listed for the V2403-CR-TIE4B)
• Confirm by engine model, engine serial number and old turbo number

Find out why the old turbo failed before you fit this one. Change the engine oil and filter, make sure the oil feed line is clean and the drain is clear, and check the air cleaner and intake pipe for dirt or loose debris. Use new gaskets at the exhaust manifold, the outlet flange and the oil connections, with no sealant on the oil side. Fill the oil inlet with clean engine oil, crank until oil pressure comes up, then let the engine idle for a few minutes before you load it. If the old turbo passed oil, clean the charge air piping and check the exhaust aftertreatment for oil before the engine goes back to work.
