The face of the Gaffrig 2 5/8" racing oil temp gage that the sensor goes with goes from 120 - 300F. I will not be ordering these sensors for a while. I've got the brass Livorsi temorarily working in the drive and need to focus on other projects right now. Let us know how they work out for you.

I called both. Yes they used to but no longer any available because the one guy that made them for everyone died and the sales volume was so low it was not worth resurecting it.

Did you get the sensors yet? If yes have you tried threading the stainless body to fit the Bravo? Results? I just ordered one for modification trial as well.

Hey Rage,
No I haven't had a chance to get around to it yet. Let me/us all know the results you get with the machining. I have a guy that owns a machine shop and all he does is threaded pieces. If you have a problem let me know. Thats where I will be taking mine when I finally order them. Still waiting to get one engine back and installed. Then I'll be more motivated.

I will try the threading die first. I estimate my chances of success at 30%. If no go I may take you up on having your machinest thread enough for us both once he is set up to thread them and split the cost. If I can get these sensors threaded I plan to send to Livorsi to see if they will work with my Livorsi gage and if so get a calibration table for the sensor.

Yeah, I'm thinking that trying to do it by hand is not going to work and I think that a land is going to have to be cut for an "O" ring seal going into the drive. For the gauge, since it's a Livorsi sender and a Livorsi guage they should be calibrated together already? I wonder if they would do the drive temp logo on them for a fee like a rebuild? I will try to get my senders ordered this week. Let's keep this going until we get it resolved. Bill

Actually I think that the bravo drive vent plug takes a gasket so no oring grove needed. There was enough of a shoulder left on the brass sensor I got to work on my drive even after the hex OD was ground down to the same diameter as the stock vent plug head to clear the Bravo case do to the recessed vent hole design. The stainless sensor should be no different ie cut the threads the entire length and partially cut the hex head down just far enough to clear the drive case recess.

The sensor is Gaffrig. My gages are Livorsi. That is the reason I will be sending the SS sensor to Livorsi for testing to see if it will work with their gages and if yes then to get my calibration table from Livorsi. If you get the Gaffrig gage that goes with this sensor you would not need to do this.

I had such a conversation with Livorsi. Just the silk screen alone that makes the black gage face markings is about $500 to tool up. And then there is the production start up costs. Not sure they would agree to do it even if someone would pay the costs for a one shot deal. But do not know unless you ask. I do not think I am interrested in going through all of that and the cost.

The sensors wire pigtail has to be tucked somewhere out of the way to cut the threads and the hex down on a lathe. Maybe check with your machinist friend and see if he can/is willing to do two sensors for you and one for me at some point?

I have been half following this thread. So I am going to ask this question. Have you thought about finding the proper thermistor that works with your gauge and then insert it into a SS housing? I have been making adapters for fill hoses and presure testers for a while. I has the 3/8" flat thread on one end and 1/8" pipe thread on the other. Now if I eliminate the pipe thread end and close off the other end, you could epoxy a thermistor in side and maybe be done with it?
Of course I dont know about thermo properties for the thermistor and the expoy in a SS case, but temp is temp.. and evently it would get to the thermistor and read on the gauge.
Tell me what you have found out about building your own..

Thanks
Dick

Do you have a picture of the SS adapter you are describing?

I know the sensor operation principle is resistive in nature but know nothing on the sensor specs. Not sure that Livorsi or Gaffrig would share that level of detail.

I use that Sender for my motor oil temp gauges ...good thing about them is the dual wire setup ...extra wire is for the gnd and you dont have to depend on the sender itself being grounded .....max temp is 300*
