Im having a lot of trouble getting the non-drive side crank off. Its a Sram Red chainset if that makes any odds. Yes, before you say it, i have probably over tightened the holding bolt. The bolt and cap came off fine,just the crank arm is stuck to the axle…. Please help 🙂

Assuming that it is the same Truvativ format as my Bonty cranks you could screw the bolt back in a bit then tap it with a hammer to loosen the axle/crank a smidge.

Tap it from the non-drive side? in turn hopefully separating the face to face metal? will give it ago….

Not sure if i’m stating the obvious, but you are using a crank puller, aren’t you?

for what its worth…
with square taper Ive found going for a quick spin round the block without the bolt in can loosen it enough, best not to have it fall off and damage the spindle/crank though…
