Crank pedal-thread damage
trail jacker
Posts: 844
Hi all,
Went out for a ride yesterday and after about 5 minutes my non-driveside pedal had loosened as i rode and has partially stripped the thread of the crank arm. Only about a quarter of the total thread is missing, and the pedal screws back in normally (not at an angle). I am really reluctant to replace the crank arm - its a brand new crankset that is literally 2 rides old. Could I put loctite in the crank arm thread to hold the pedal in place? I know normally you use grease but considering the thread damage I am a bit worried about it reoccurring. Thanks!

or take ot to your LBS or an engineers shop for a thread saver/ helicoil.
it is a common issue."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Happened to me with a brand new Boardman Comp HT, took it back to Halfords and they replaced the crank arm under warranty.2012 Boardman FS Team

Yeah, I have noticed its pretty common - they could do with having the pedal axle go right through the crank arm and then be secured by a lockring on the back of the crank arm or something, guess I will see how tight I can get the pedal then take it from there.Carbon 456... http://www.pinkbike.com/photo/8854609/0 -
back to the shop
the crank was not heat treated correctly at point of manufacture0 -
That's a massive assumption and probably hopelessly wrong!Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0
