Well while mowing the lawn today the tractor died. Open the hood to take a look and the spark plug blew out of the head. Can i helicoil it? Do I have to take the head off to do it? What size am I looking for
Just to be clear, the one I use is not exactly a helicoil, which is kinda like asking for " Kleenex" which is a brand of tissue, not the product.
" Helicoil" is kinda like the same thing, there are several types.Most are a coil of wire that just goes down into the threads.
The one I used is more like a time-sert, which is a full threaded sleeve, complete with a flanged top to receive the spark plug compression washer . While not exactly ideal , they sure do work well, especially if you want an engine running, and cannot source a replacement head.
