pyrometer question

[dyoung14]

well in my deal with punkmechanic, i also got a pyrometer, well i have never had a pyro,lol, so on the probe that goes into the manifold there is what looks like a nut that is soppose to thread on this other thingy he gave me and the nut on the probe is stuck i think, i have tried every way i know how to get it to move, what am i doing rong?

The probe and the nut should be one piece...won't it thread in? If you could post a pic of how it is it might help.

got to find the camera, may be tomarrow before i can

well i found the camera now im looking for batteries lol

this is what i got

The "nut" on the thermocouple probe is part of the probe.
One end of the bushing ('thingy') threads into the manifold (or wherever you want to put it) and the probe goes through it and the "nut" threads onto the other side of the bushing.

i have tried to thread it it dont work, it dont even look like there is no room to thread anything in it?

 

[punkmechanic]

hey its me. Im psuedo back from the dead (trip to cali, 3 long days at work, wisdom teeth out and side work, all in 7 days)

I guess I got the probes mixed up. I meant to send the one that had free threads and not that one that has the piece broke off in it.

the only way I have been able to get them out (I have dont a few now) is to heat the hell out of it with at torch. be careful not to bend the thermo probe itself or melt the wires that come into it. It takes some doing but it will come out. Let me know if it gets outta hand.

You have to drill and tap the manifold for 1/8" pipe tap. Then the brass "thingy " install's in the manifold, then the pyro slides thru the brass thingy and then screw's onto brass thingy.
Make sure you hook the wire's from the pyro gauge RED to Red and YELLOW to Yellow and don't cut the wire to length, wrap up the extra length if any. The gauge is calibrated to that length wire.

 

[suv7734]

In looking at it again in Photoshop punk is correct that the nut should have some male threads.
Depending on the gauge it should be a type K thermocouple which will be yellow and re leads. The yellow is the positive.
If by chance it is a type J then the leads will be white and red, with the white being the positive.
Make sure all connections are done 'mechanically', IE don't solder anything or you won't get an accurate reading.
Use only the correct thermocouple extension wire that came with it and if you need it longer then get a length of the correct extension wire. The material is what's important not the length.

i dont realy think there is enough sticking out to grab ahold of to get it out?

 

[dyoung14]

well i looked at it again, there may be just enough, but im not going to f'ck with it or i will really screw it up, so im going to take it to my grand pa and see if he can get it out.

 

[punkmechanic]

I usually use heat liberally and a small chiesel. put the fitting in a vise, apply heat and use the chiesel to get the threaded piece to turn. It isnt too hard, but it can be a little time consuming.

exactly why im going to let my grand pa get it out for me, he is very patient and im not very paitent if i do it i would end up finding a big hammer lol

 

[punkmechanic]

whatever works. for the record I have found these trucks build patience. Its required for my rig at least. I love it but she can be a pain in the nuts when she feels like it. Return line leaks, stuff I have changed, messed with, or havent touched yet (but the po did!!! lol). Its a slow going battle, but slowly she gets better and better.
