Installing Bobbins - Engine Bolt is twisting on the spot

Post by parsasm »

Hi everyone,
Hopefully I've posted in the right section,
I'm trying to install my bobbins, but the original engine bolt is spinning on the spot, I can't get it out and I can't twist it back in, it just twists and twists!
Any idea what I can do please?
Thanks

sounds like the thread has gone, you will need to pull and twist to get the bolt out, then you will need to either fit a helicoil, or drill a bigger hole and tap it for a new bolt.

if these are crash bobbins, thene there is a nut on the other side that fits into a lot on the motor. all you should need to do is replace that. But if th nut is still there and the thread isnt taking then id suggest checking you have the right part or checking that the nut on the other side hasnt fallen out...
