Help - Stripped Thread!!!
 

I took my undertray off today, and thought while I was there I'd tighten up a bolt that oil was leaking through. So I had to undo a bolt on the engine cover (right hand side, where the oil goes in) to take off the undertray bracket to get to it. Tightend up the offending bolt, went to put the bracket back on...but the thread has stripped, on the engine point.

So now I have a leaky bike...how do I mend this? I know the thread has stripped because little bits of metal where coming out when I brought the bolt back out

I really don't know what to do, this is way beyond me

You could try to cut a new thead with a tap. I'd try this first. If that didn't work, I'd get a new bolt the next size up and cut a new thread with the next size tap.

This is what I would do. Not saying it's the best way.

i would get a tap and run it in well actually first i would make a thread chaser. take a bolt the same size take a cut of wheel and make a grinding notch length wise on the bolt so you cut through the threads so when you run this bolt in it helps clean up the threads. if not use a tap. if that doesnt work come back to me for more ideas

Ok, thanks guys. It dosnt look like a difficult fix, but I'l have to conscript someone to help me out as I dont want to balls up making another thread

I guess its unwise to ride the bike...?

Re: Help - Stripped Thread!!!
 

firs tplease describe in more detail which bolt it is

Re: Help - Stripped Thread!!!
 

Its silver and on the engine casing :smt118

Any help :smt043

Re: Help - Stripped Thread!!!
 

Plowise is correct! Its on the cover on the RHS (as you sit on the bike) and is silver. Its the bottom most bolt. I've rung my Cheif Engineer (AKA dad) and he said take the bolt out of the belly pan bracket, put on loads of PTFE tape and stick the bolt in; Its might do up if theres enough thread left in the end of the bore hold (its the female part, isnt it?)

Anywa, ydone this, and the bolt is done up nice and tight. I'll leave it for now then, and have a bit of a wobbly belly pan. My dad thinks its because we've had that bolt in and out of the bike loadsa times trying to fix a small oil leak, and its but too much stress on the thread

Oh well, it'll do for now I think.

You should get it helicoiled - I wouldn't tap the hole out to the next size up, and whatever you do be careful not to force anything too far into the hole and break through the back of the hole. I can lend you an M6 helicoil set( I think that is the thread size) but you need an amount of care to use it!
