Pyro probe install

[tech10002]

I've got most of my quad commander install done except for the pyro probe. I'm installing that tomorrow and just wanted some opinions on the proper technique for drilling a tapping the manifold. I've read 100 different methods on how to do it. Some say you must remove the manifold. Others say do it with the engine running. Some say don't idle the engine. Some say to use grease on the bit and tap. Others say don't. LOL

What's the best technique?

tech this might help ya, someone posted this on here a while ago where they show how to do gauge install, if ya click on the pics they give a small write up on each step. Other then the way they are doing it in this pic i have only seen them use a small magnet to get the shavings.

I just did mine a couple of weeks ago. Dieselmanor.com says to NOT run the engine and NOT to use grease. The flutes of a drill bit will bring out the shavings. Just start with a small drill bit and work your way up to the right size. It'll keep the shavings small. Might wanna wear some glasses. Then when the probe will almost fit just rock the drill bit around to bell out the hole a little. Don't over drill it. Hope this helps ya!

i took my manifold off because i didn't want any metal shavings to go into the motor..

Yeah theres nothing wrong with going the extra step. Your bolts that hold it on are probably not rusty like mine are, so i didn't want to take a chance on snapping one off and then uh oh But if you take your time no shavings should go up into the pipe.

yeah the truck was brand new when i did it so it was a little bit easier..

did mine a coulple weeks ago and i drilled mine with dry drill bit. all the big shavings fall straight down since you are drilling on the bottom of the manifold.then just use a shop vac to suck out any small shavings that may remain. i read somewhere that the very small shavings will get blown out without hurting anything. hope my 2 cents helps

Cool. I printed out those instructions. It doesn't look as bad as I thought it was. I guess I'll have to take a trip to Sears tomorrow and get a tap and long extension.

I got it installed. It wasn't really too bad. There's not a lot of room to get the tap in there, but I used an open end wrench to turn the tap instead of the handle, and that worked out pretty well. I also ended up removing the front driveshaft. That made it a lot easier to work.

I'll post some pics later tonight after I get home.

dont forget to use a little anti-seize in case you ever need to take it back out for some reason it will make it a lot easier.
