Hi all, glad I found this place. I just bought a BX2200; it's both the first tractor I've owned and the only tractor I've ever used, so I'm sure I'll have a bunch of questions.

Does anyone know what the thread on the oil pressure and coolant temperature senders on this machine are? I did some googling and found that some of the larger Kubota tractors use 1/8 BSPT for the oil pressure sender, but I don't know if that applies to the BX2200. I couldn't find anything on the coolant temperature sender at all.

I need to fit a couple of aftermarket senders to the engine.

I'm looking to add some actual instrumentation to the machine in place of the stock oil pressure warning light and unit-less, "it's either in the red or it's not" coolant temperature gauge.

So, I'll be replacing the stock coolant temperature sender and oil pressure switch with VDO parts that have the correct ohm range for VDO's gauges. I was hoping to figure out what adapters I need without having to pull the old senders and measure them, so I can just get everything ordered and done in one go.

I put a coolant gauge on a D662 engine that I swapped into a G4200. The D662 was out of a Toro greensmaster, I think.

Anyway, the coolant port was 3/8" pipe thread - probably BSPT since it is a metric engine, but NPT works well enough in this low pressure application. The engine that I swapped already had a coolant sensor in the water neck and it worked fine with the $9 "dragon gauge" LED coolant gauge that I bought off of ebay. Most gauges use a standard 0~1000 ohm sensor.

The oil pressure switch is 1/8" pipe also. Again, it is probably BSPT, as the NPT adapter would only thread in a couple of threads before tightening up. I ended up running a 1/8" NPT tap in the hole - coated in grease to keep the chips out of the engine - and all is well.

The ports in your engine are probably the same as the D662 - Kubota likes to standardize - which makes things much easier.

Hope this helps.
