I just got a Marin 24" MtB the right crank arm is about 1/2 stripped from the pedal not being fully tightened before riding. I tried doing an internet search and I only see left crank arms. is it possible to use a left side on the right drive side? Not sure what the numbers mean 42/32/22 ? I think the arm lenght is 165 I was hoping that 1256A1 would be a good part number to find the right crank arm. I am pretty sure this is a 3 piece crank. not definate as this is new to me.
I saw some videos on retapping the threads .. i have a tap and die set i borrowed from tool library but the videos suggest special "bike crank" taps. I dont have a vise either at this point in my apartment.
is there a safe way to get the crank arms off without a puller? when I was young bikes didnt need all these special tools. wow! things change thanks
