Removing a stuck pedal spindle from crank - I HAVE SINNED RADSTERS

(1/5) > >>

BMX1973:
I can not remove the crank from my frame, as the pedal spindle is stuck on the non drive side. Tried everything from WD40 to placing it in a strong vice.
Any ideas?  :-\

 :daumenhoch:

Munnyella:
Awkward with it still in the frame, but try and clamp the crank in your vice, spindle pointing up, correct size spanner on the pedal spindle ( with other end cut off spanner if needed,) bit of pipe/pole over spanner, hold and walk backwards! getting it hot will help too, but not too hot if its chrome and you are hoping to use it, it'll go blue.

Good luck, it will come off, the only one that has ever beaten me was on a 3 pc, that someone had cross threaded 2/3rds of the way in, fook knows how they got it in that far, but I had to get the crank glowing to remove it. and now I have a baggy pedal boss!

RATTY:
Might sound obvious, but dont forget cranks are left and right hand thread!! Are you undoing it the right way?

Discostu:
Yeah I was thinking the same ratty.
On the chainring side it is anti clockwise to undo.
And in the non chainring side it is clockwise to undo (as this side is left hand thread)  :daumenhoch:

thecaptain:
Another way, if slightly destructive, is to use a dremel with disc cutter and cut around the pedal, only 0.5-1.0mm, so there is a slight gap between the crank arm pedal boss and pedal axle shaft, then unscrewing it becomes super easy.

dont try it if your desperate to keep the pedals in good condition though
