Title: pedal problems.
Post by: magna13 on March 22, 2009, 02:37 PM

hello guys

right got the new United bb on my bike it goes like s*it off a shovel, im really pleased! :smitten:

now i got a new problem  :( yesterday i went to St. George skatepark in Bristol and then me and my mates decided to go to a quality bmx shop and i thought i'd buy myself some 'Seventies' plastic pedals that totally match the colour of my bike :smitten:, fitted the left one sweet as a nut but the right one will not budge! now i run Primo Hollowbite cranks and where axle of the pedal threads in there is an insert and whenever i turn it to get the pedal off the insert just goes round and round and then goes extremely tight and the pedal wont budge! :'( :'( what do i do!!

thanks zak

There should be an allen key hole in the pedal axle that you can get at through the crank arm.  remember to turn loose, turn towards the rear of the bike on both pedals.

It's the steel pedal boss in the crank that's turning; using an allen key won't make any difference  ;).

Like Dodger said, you might have to line up the small hole (if that's what it is at the top right of the stell boss) and tap something in there to keep it in place.  Failing that, a machine shop might be able to help as you would need to grip the steel boss in the crank to hold it while undoing the pedal, a reverse chuck (similar to a lathe chuck) might be able to hold it, otherwise I'll be fooked if I can see a way to get it out  :-\ .
