Exhaust Thread Repair

[Garry H]

I Have been thinking about a good way to repair stripped exhaust threads for a while now...Crap day so i have been playing about in the workshop....I have been thinking about this for a while and came up with this way

 

[Garry H]

This is the hard bit screw cutting a new thread once you have machined down the knackered thread

 

[Garry H]

You now have a new thread thats too small ..
So i could make a new nut to match the undersize thread or if you want to use a standard nut a collar to adapt it back to the correct size...Being made out of brass it won't pick up again

 

[Garry H]

Screw the new collar on...No welding or shrink fit

 

[Garry H]

And there you have it ...Good as new

Firkin Gorgeous, well done!

Someone will be along in a minute to ask what you did to stop the threaded bush unscrewing........

This is the same method that my local engineering shop use - But they also pin the brass sleeve, as they found they will come undone, even in everyday use.

I won't say how much they charge to do the work £££££

 

[Garry H]

I would put a pin in to stop it turning/comming undone...but because this is a scrap head i used just to prove i could do it i didn't bother...I could do this for people if they want...But it is a fair bit of work so would not be cheap...but it would be a excellent repair

Aye that's how mine was repaired, think 40 something squid via Motobins, but 2 pins, one of which is not such a great good as it's come through the alloy a bit. still, does job. Now I'm sure there's a market for you Garry should you get bored

Thats a great bit of turning and I can understand the amount of time it takes to set up and machine.

very nice piece of work. I'd be well chuffed to see that work done with my own hands.
