python_man Posted January 25, 2008 Report Share Posted January 25, 2008 i have an echo old crank not sure of the model or age but the pedal thread is slightly stripped.was gonna helicoil it but remembered it is a left hand thread. was thinking if i heli coil from the other side (side facing the frame) outwards then it would be left hand thread when i put the pedal in from the correct side.anyone else think this would work~????

cai Posted February 4, 2008 Report Share Posted February 4, 2008 I hope it will work, because i've done the same thing to my brand new echo forged crank (left hand side) aswel.Well to be fair it wasn't me it was my mate who did it while I was tensioning the chain.I don't know much about helicoils, i thought you could only get them in maggie mount sizes, where can you get ones the size of pedal threads?

Tony Harrison Posted February 4, 2008 Report Share Posted February 4, 2008 You can get helicoils in a myriad of different sizes. Remember also that's there's the diameter of the thread and the pitch.The simple answer to the first point is NO you most certainly can't use a right-handed (i.e. 'normal') helicoil in a right-hand crank. The right-hand crank has the left hand thread, and this needs a left-hand helicoil. Putting in from the back makes no difference!! Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 4, 2008 Report Share Posted February 4, 2008 I thought right hand size cranks still used regular threads, but it was left that was opposite threaded? At least I'm pretty sure it is.The right side BB cup uses opposite thread, but not the crank. Quote Link to comment Share on other sites More sharing options...

psycholist Posted February 5, 2008 Report Share Posted February 5, 2008 If it's a drive side crank then it's a right hand thread, if not it's a left hand thread. Putting the coil in from the other side will not change the threading direction. If you use two right pedals it'll work, but the right pedal in the left crank will almost certainly keep coming loose due to thread precession.

python_man Posted February 5, 2008 Author Report Share Posted February 5, 2008 ok then will over sizing the thread and using a tensile insert work. but will the insert have to be left hand thread aswel???? Quote Link to comment Share on other sites More sharing options...
