Frozen Wedge Nut--Tips ??

Anonymous Sun 28 May 2017 12:31:09 No.1076435 View View Reply Original Report

Anybody have a tips for removing a frozen
wedge nut from a tube ? Tried placing block
of wood on bolt & hammering down...no luck.

Currently letting it "soak" in some PB Blaster
hoping that it will loosen it up. Vintage late
to mid 80's frame..most likely some fusion has
taken place.

Tips ? Advice ?

Have you tried it without the block of wood? Also, make sure to support directly against the tube under the fork crown or you will kill the fork. Use the stiffest support you can - like letting the fork straddle pic related. Try both solid and rubber mallets.
Often, just having a dead, stable support on the other side of the blow makes all the difference. It means the force is acting where you want if to act rather than compressing the block of wood or whatever you had.

Didn't even think of that;makes sense. Pipe
fence would be ideal but gaining access is
another thing. Thanks for the tips.

Naval Jelly to dissolve the rust.
Breakfree brand lubricant/protectant to help loosen it.
Heating the affected part with a heat gun (or blowtorch) to cause expansion of the metal, breaking the structure of the corrosion.
Going over to /diy/ and asking them.
Googling "remove rusted bolt" instead of asking a bunch of NEETs who hang out on a Japanese image board.

If the thread in the wedge is still good you can try pulling instead of pushing. If the bolt is long enough insert it from the bottom of the fork crown through a washer that's larger than the steerer (a top cap would work if you have one laying about). You could also try some threaded rod with a nut on it, use vice grips to hold the rod from turning and a spanner on the nut, you'll get more leverage than with an allen key and it'll take more torque before stripping out.
