This is a new, genuine Kubota common-rail fuel injector kit, part number 1J600-53073. Kubota files it in its 1J600 part series, the series it uses for the V5009, the 09 Series four-cylinder diesel: Kubota’s own filter and DPF guides list 1J600 numbers for the V5009, Kubota’s name for the 1J600 fuel rail is RAIL,ASSY V5009, and the 1J600 fuel system has a supply pump, a fuel rail and four injection pipes. The V5009 is a 306.2 cubic inch (5.0 liter) common-rail engine with DOC, DPF and SCR aftertreatment. The engine takes four.

Common-rail injectors are usually replaced after a failed fuel return test, an injector or cylinder balance fault code, hard starting, rough running or white smoke. Water or dirt in the fuel is the usual cause, so sort out the fuel supply and the filters at the same time. The V5009 is an industrial engine fitted by equipment makers, so order by the engine serial number rather than by the machine.
