City Cycling Athletic Club Posted May 26, 2017 Share has anybody had any experience of removing pedals by spark erosion - pedals need to be replaced urgently Link to comment Share on other sites More sharing options...
BaGearA Posted May 26, 2017 Share I'd try heat shcok before I try that. Have you tried an allen key and long pipe ? Link to comment Share on other sites More sharing options...
V12man Posted May 26, 2017 Share Make 100000 percent sure you are turning it in the correct direction and use a longer lever.... or just visit your local bike shop. I have had broken cylinder head bolts removed by spark erosion... works well but probably unnecessary on stuck pedals- especially since it guarantees destruction of the pedal.

City Cycling Athletic Club Posted May 26, 2017 Share twisted the LBS's allen key like liquorice - got new pedals to fit - old ones too worn even to keep as spares.currently dripping lemon juice on them every hour. LOL. will ask around for someone with a blow torch. Link to comment Share on other sites More sharing options...

Mathieu_Schneuwly Posted May 26, 2017 Share If the pedals are toast regardless, and depending on the pedal, this is an easy solution - have done it twice: Strip the pedal so only the axle is in the crank. Take the axle to the grinder to create flats. Hold the flats in a vice. Twist the crank. Link to comment Share on other sites More sharing options...
Kalahari Vegmot Posted May 26, 2017 Share Big vice. Drown the thing in Q20 overnight. Clamp tightly and hammer. Smile as you hear the creaking sound of the pedal loosening. Link to comment Share on other sites More sharing options...

milky4130 Posted May 26, 2017 Share I've seen this way too often & willing to bet money that it's being turned the wrong way. Link to comment Share on other sites More sharing options...
ABrooks Posted May 26, 2017 Share Isn't there usually an arrow on the crank arm showing which way to tighten? Link to comment Share on other sites More sharing options...
Frosty Posted May 27, 2017 Share To loosen, turn towards the back wheel, i.e drive side is counter-clockwise while non-drive side is clockwise. Pedals always tighten in the same direction as the bike moves... towards the front Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
gummibear Posted May 27, 2017 Share Isn't there usually an arrow on the crank arm showing which way to tighten?Nope....but pedalling forward tightens the pedal so to loosen push towards the back wheel. Link to comment Share on other sites More sharing options...
ZakAttak Posted May 27, 2017 Share Please, please, please put copper grease on the thread of the new pedals when fitting them, in fact put copper grease on all your screws/bolts etc when fitting them... it will prevent the unnecessary struggle to loosen said component when needing to replace/service in future Link to comment Share on other sites More sharing options...
Tony datoy Posted May 27, 2017 Share There are three words that come to mind " lack of maintenance" how on earth do pedals end up getting stuck if you are servicing your bike? I remove mine at least every three months, strip and re-grease. Apply a little copper slip on the threads when you eventually get to fit new pedals.

Odinson Posted May 27, 2017 Share Unless you have brand spanking new Eagle cranks (which I don't think you do), just chuck your crank with the pedals attached. Link to comment Share on other sites More sharing options...
etienne_jordaan Posted May 27, 2017 Share I would not recommend any heat or flame on a carbon crank. Aluminium maybe, but very low heat. Link to comment Share on other sites More sharing options...
