I know this is a stupid question, he goes anyway. My BX2350D instrument cluster has a dead fuel Guage and water temp Guage. Temp sensor ohms ok, as does the wiring. The rpm/hrs meter works fine. Not too worried about the fuel Guage, but I am about the water temp Guage. I want to install regular waterproof marine guages for the tach/hrs, water temp, oil, batt, and an idiot light for the glow plug. Here is the stupid question does anyone know the thread pitch and size for the Kubota temp sending unit that screws into the head? It would keep me from losing antifreeze to take it out. Could it be 1/8 npt? Or do they have a metric pipe plug size. I really find it kinda hard to part with $700 for a Kubota Guage cluster. Considering I've read posts on here saying some have had moisture issues. Any help would be appreciated.
