Alternative to HeliCoil?

[Russ]

This past sunday I was riding my bike home from my dad's and I had the front right spark plug blow out of the cylinder. After talking to squidley, he said that we can heli coil it. So I went in search of info of what I need to do... and I came across a product called Time-Sert. I wanted to find out if anyone here has had experience with this product and what their opinions are compared to HeliCoil.

I've never used those but they look pretty good. It's been a LONG time ago that I used a helicoil either so I really don't know which would be the better choice.

I know and use both, Helicoil and Time-Sert.

 

For me, depending on the Application, like Sparks-Plug Threads and also like Drainplug on the Oilpan, Time-Sert is the better Choice. I use them everywhere on Parts who are in need to be sealed inside the Repair-Thread against Fluids or Gases. I use blue Loctite 628 for fixing and sealing the whole Insert while turning the Repair-Insert in.

 

imho, Helicoil is better on Applikations where strong/heavy Torques are needed. The Helicoil Insert is relaying the inside Pressure behind the repared Thread towards the outer Sealing of the Screw or the Sparkplug. That's because the Insert is like Wire and cannot Seal the Thread itself. The Tinme-Sert is a complete Collar, which can easily sealed on the outside of the Thread.

 

Again, both Systems will work fine on a Sparkplug-Thread Repair, for me it is just a Case of Good and Better.

 

Edit:

As i reread my Words, i hope that you understand what i'm trying to say. Today so far, no chance for a better Expression of my Thoughts ... :whistling:

Russ I am an industrial maintenance Tech. with a machinist background. I use a variety of the Time-Sert (called Keenserts) and they are far superior to helicoils. I threw away all my helicoils once I saw the difference in durability. Just make sure you get all the shavings out of the cylinder!! Dave
