Kickstand mounting bolts stripped

[Sparky731]

It looks like your bolt hole is hollow in the middle.

The kickstand side probably isn't threaded, so that the bolt can thread into the rotor side and pull the bolt tight on the kickstand side.

When your bolt broke, there was probably some good thread in the hollow space in your frame that was easy to thread in with the bolt to push and turn the stud.

The stud is probably slightly damaged at the broken point and that's when your stud stopped turning easily.

The stud could probably thread in easily the other way because it's all clean thread but it may fall into the hollow space in your frame instead of out through the bolt hole.

Turning your stud out now in the same direction as you have been going, is probably going to be difficult because the damaged thread at the break will have to scrape through all the threads on the rotor side of your bolt hole.

Repair success. I purchased 25mm & 30mm #6 cap screws with various possible nuts and washers.

The enabler for removing the broken piece was my previous attempt that exposed a sufficient length on the inside of the frame to work with into which I was able to cut a screwdriver slot.

The rear hole’s threads were intact so I used the longer 30mm bolt and was able to catch and tighten into a locking nut.

About 1/3 of the front hole’s outside threads were damaged, but the remaining 2/3 were wholly adequate. I was unable to secure a lock nut tightly enough to catch it with the bolt, so I discarded that attempt.

All seems to be sufficiently repaired for now. Should it fail again, I will drill out the internal threads which should enable a tight grab into a lock nut.

Definitely something to watch further for looseness. Thank you all for your helpful advice!

nicely done, exactly what i would have done! i had to cut a slot into a very stuck bolt lately, always works better than extractors for me when you have good enough access for the dremel
