Re: Replacing Stripped Glow Plug Threads Cougar I have an old webra that could use repair. there's still some threads left but I'd prefer full threads. I was going to buy a timesert kit myself as I can get them through work and they are the best quality repair. What kind of money were you looking at for repairing it yourself? |

Re: Replacing Stripped Glow Plug Threads Thanks. If I have enough replies I will go ahead and order the kit. For some info, here is the link to the kit: http://www.timesert.com/html/0142-note.html |

Re: Replacing Stripped Glow Plug Threads Let us know Gary when you have your new gadget, maybe any of us who have stripped plug holes could send them to you for repair and help justify your output. I know I will if your interested. Bill |

Replacing Stripped Glow Plug Threads I lucked out last fall, picking up a very low time Saito 125a laying amongst a few others at a swap meet for $60. I confirmed my quick and dirty assessment once I got home and opened it up. ALL that was wrong was a seriously cross-threaded glow plug hole. Years ago when I was in the auto trade we used TIMESERTS to repair stripped plug threads in alloy heads, (remember them touting "100 thousand miles before the first tuneup"?). Anyway, I grew to trust them a lot and decided to have a boo to see if they had a kit available for the odd thread pitch and size we use here. Worked out they do and I am looking to ordering one. Even with the cost I would be way ahead once the Saito is serviceable again, but that cost is a bit hard to justify for a single repair. There are several parts to the kit that are unique and only the inserts are reduced in number for each motor. I am looking to see if there is enough interest to offer my services and in that case will order extra inserts. I would think the best method would be to send me a PM to that effect. NOTE: These are NOT Helicoils, but internally and externally threaded flanged inserts that permanently lock into place during installation. The heat transfer is much better and there is NO chance of the coil unthreading, (or worse, dropping into the cylinder during plug installation). Personally I do not think Helicoils are a good option for plug thread repair in alloy heads. The thermal expansion characteristics are too different. Consequently during every heat/cool cycle wear will occur. That wear increases the possibility the coil will unlock and turn within the alloy when the plug is removed or installed. Unfortunately during installation you would not be able to tell if that occurs and only minimal thread engagement occurs and some coils now project into the combustion chamber. Also, the heat transfer is not as good as it could be. We use Helicoils in the aerospace industry and for the right app they are fine. __________________ |
