So my oil pressure switch failed at 110psi. Its stuck there and won't go up or down. I checked to make sure it wasn't my tuner and even unplugged the switch... When unplugged it drops to 0. Soooo I looked up the switch.... Its like 200$!!! You HAVE to be kidding me!!! The V8/v10 are only 20$!
Please tell me there is some cross referance part or something?? Maybe a little cheaper!

Thanks!

 

One thing you could try is removing the sensor and checking for debris in it. Sometimes a good hard smack on a steel table will allow the diaphragm to move back out.

Otherwise, going directly to Cummins will be cheaper. Case and New Holland tractor dealerships use this engine in their equipment as well. Could be cheaper through them, I know crank seals are.

 

I just bought a sensor directly from Cummins, Part # 4921511 cost about $90.

Hope that helps.
