now i've stuffed it. ive cross threded one of me plugs. plug is out,but thread on head stuffed. and i mean stuffed. would it be easier/cheaper to fit a new head,or have it rethreaded? has anyone used that thread repair goo,any good? is it best to remove head before attempting any fix it proceedure? am thinking of taking head off,and useing a die set to rethread it. starting from the bottom,as it's the top couple of threads that are stuffed. HEELLP! :cry:

Helicoil...

Post by Prof » Thu May 03, 2007 8:50 pm

This is the sort of thing you are looking for... This is for redoing 5/16 UNF. Comes with a thread tap for the stainless coils that provide the new thread, set of coils, a tool to drive them in and a tool to remove the tang. An instruction sheet includes drill bit size needed to drillout old thread.

I went to grab my set for doing plugs and I realise I've loaned it out and its still out...oops!

Plug thread set I use is a bit different and has a solid section to be threaded in.

CBC Bearings has always been well priced. Take in your plug so you get correct set up and get them to show you the options.

Removing head is best, so you don't end up with loose aluminium shavings in the cylinder.

another option since you are already going to be taking the head off is to have it welded up and re machined. I had a Helicoil let go on my Shovel which resulted in me copping a spark plug in the back of the leg at rather high speed (REALLY BIG OUCH). I really didn't trust the idea of another Helicoil after that and as it worked out it only cost me $50 to get the whole job done properly without the fear of having another plug fly out and hit me.
