417A pressure sensor

Recommended Posts

I have a model 417A with a Kohler series I I engine, spec number 24363.  The oil pressure sensor is leaking.  I can not find a part number for it anywhere.   All the diagrams I can find show the switch but give no part numbers.  Does anyone know what the part number is?

Thanks

Okay, got the switch and went to put or on and the adapter broke.  I ran all over town looking for the adapter but can not find it.  I didn't see it in the parts list umess it is something eles.  Any  ideas on the part number or type of adapter I need?

Thanks

The block is drilled an tapped for 1/8 27TPI pipe threads...which is what the pressure switch should have..no adapter needed unless you have a clearance issues with the ear on eh bearing end plate.  In which case you can use brass 1/8" pipe fittings to solve it  probably a short nipple and a connector.

The pressure switch threads are 1/4"  I believe.  I  have attached pictures of the switch and adapter.

Still pipe thread get a reducer like this and 1/8" nipple and you are set.  Any hardware store should have it.  You might even find a 1/4 female 1/8 male making it a one piece solution.

My KT 17 did the same thing. But I couldn't  get the other part out of the block, so taped it 8-32 and put a set screw in it to stop the oil from poring out. Ill have to pull the engine and drill it out and tap it 1/8 inch pipe thread later this fall.

Good auto parts stores should have a large cabinet with a selection of brass fittings for brakes , oil and fuel . If it's an Edelman assortment - it should have the short 1/8"NPTx1/4"NPTF reducer as that one is specific . Otherwise , check with McMaster - I believe they keep them in stock . Some of the home centers also have extensive brass fittings , but good luck trying to hunt through them .
