This is a new, genuine Kubota turbocharger assembly, part number 1J403-17016. It fits the Kubota V2403-M-T, the turbocharged 2.4 liter (148.5 cu in) four-cylinder of the 03-M Series with indirect injection and an in-line pump, and turbo catalogs list it for the V2403-M-T-E3B. Mitsubishi builds it for Kubota as a TD03 (TD03-07G) with a wastegate and a pneumatic actuator. It is Kubota’s current number for 1J403-17013 and 1J403-17015.

This is the turbo for the mechanical V2403. The V2403 in Bobcat machines and the common-rail V2403-CR engines take IHI turbos under other Kubota numbers, so do not order by engine size alone. A turbo is usually replaced for shaft play with wheel rub, oil leaking past the seals, a noisy or seized rotor, or a wastegate that no longer holds boost. Oil starvation, dirty oil, a blocked oil drain and dirt past the air filter are the usual causes, so find the cause first. Do not confuse it with 1E013-17016, the Mitsubishi TD03 for the 2.0 liter V2003-T: the two carry different Mitsubishi numbers.

Specifications

Fits / Applications

• Kubota V2403-M-T turbocharged four-cylinder diesel, 2.4 L (148.5 cu in), mechanical injection (listed for the V2403-M-T-E3B)
• Direct replacement for Kubota turbochargers 1J403-17013 and 1J403-17015
• 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.

Frequently Asked Questions

Which engine does the 1J403-17016 fit?

The Kubota V2403-M-T, the mechanical-injection 2.4 liter turbo diesel of the 03-M Series. Turbo catalogs list it for the V2403-M-T-E3B. Call 530-668-0818 with your engine model and serial number and we will confirm it.

Will it fit a common-rail V2403-CR or a Bobcat V2403?

It is not the listed turbo for those engines. They take IHI turbos under other Kubota numbers, such as 1J808-17010, 1J803-17012, 1J802-17010 and 1G491-17012. This one is the Mitsubishi TD03 for the mechanical V2403-M-T.

What numbers does the 1J403-17016 replace?

Kubota 1J403-17013 and 1J403-17015. Earlier units also carry a Mitsubishi number on the tag, such as 49131-02090 or 49131-02093.

Is it new or remanufactured?

New, genuine Kubota. It is a complete turbocharger assembly, not a rebuilt unit or a bare cartridge.
