Transfer case plug helicoil?

Joshua993 · 06-12-08, 07:05 AM

Saw my truck was leaking at the T-case fill plug. When I tried to tighten it, it just spun. I got it out, and found the threads of the plug packed with...something metal, which I was able to spin off of the threads. I will try to post some pics soon.

Now I need to repair this. Does anyone know if the fill plug is heli-coiled? My thought was to tap the threads, and put is a M18 helicoil. Finding one that size has been tough though...

If it's just a plug (for the filler hole?) just tap it out to the next size, IMHO a helicoil job isn't really needed if its not supporting anything

I had this very same problem and thank goodness it's only the fill plug. I'm pretty sure there isn't a coil that big, but I did find something else that may work...try this site... Over Size and Repair Oil Drain Plugs . I ended up just wrapping mine in thread tape and using a small piece of metal that attached where the wire comes out of the T Case to hold pressure on it so it would never fall out. Sounds crazy, but I haven't had a leak or any issues. I'd take a picture for you, but it's been at the tranny shop for months

...not due to the above mentioned fix
