Question about tightness of Freehub body bolt

bus_ter

I've just replaced the Shimano Freehub that failed on my wheel (started to spin in both directions).

I bought a specific heavy duty Park 10mm wrench for the job. It took a bit of force to remove the old freehub even with the large leverage from the tool.

Fitting the new one the bolt went quite tight and then I gave it a little elbow grease to tighten it right up. However it gets to a certain tightness (which is very tight considering the leverage and tool) but won't go any tighter and keeps turning. I gave it 4-5 1/4 turns at this force and it didn't get any tighter. It seems pretty secure and I put everything back together. I didn't want to keep turning it in fear of breaking something.

Any ideas?

If a bolt is turning but isn't tightening the threads must be stripped surely !!

Sounds like the thread is stripped to me as well.

So basically I've over tightened it? What sort of torque should a freehub go on with?

Ok 35-50nm. Surely I didn't surpass that with a large allen key? Or maybe I don't know my own strength. Maybe it was the tool slipping? Oh well it seems secure and I expect the new freehub will out live the wheel (or at least the hub) and I'll never have to try and remove it.

I doubt you've stripped it by overtorquing; more likely that you've cross-threaded it.
