[Closed] Help removing sram crankarm

It's hammer time.

Seriously? I actually tried to put my weight on the allen key by stepping on it . Still failed

Yeh, the shock often help. A reasonably heavy rubber mallet is what you want.

Was there a 10mm hex nut on the crank arm? If so that needs replacing, thden use the 8mm to remove the crank arm.
Give it a generous dose of wd40, and once thsts had chancd to soak in a gentle persuade with a mallet.

You're definately trying to turn the inner (small allen key) one rather than the outer (big allen hey) one?

Longer bar- the nut is at a pretty respectable torque, 50nm if memory serves, so if by some miracle it's been fitted for a while (ie the BB didn't wear out the first time you rode it) it could take a fair effort to shift it. I go directly to my 2 foot bar for stuff like this...

I'd agree with using a longer lever (plus making sure you're turning it the right way) - I've got a 2ft long torque wrench arm and it was still an effort to get the appropriate torque when doign my sram cranks up.

I had to do the same recently and had similar issues

found a 30cm hollow bar which fitted snugly over my allen key and gave me the leverage needed to get it undone.

summary - MTFU 🙂

Cheers guys will probably need more leverage. Believe it or not all this trouble just to fit properly a rear derailleur outer cable.. Somebody should fire whoever design cable routing for yeti such a muppet 😡

@mega .. Where can i get that 30cm hollowbar?

I used an old bit of pipe which was lying around in the garage

sprayed a bit of wd40 an hour before trying but my cranks were old and manky - yours look quite new so you might not need that.

why do you have to take the crank arm off? Are you routing the cable under the crank or something? Isn't it easier to undo one end of the cable?

Oh - Hold on!

Are you sure you are supposed to be undoing non driveside? My cranks undid from drive side but it can vary depending on model.

Because some genius in yeti thought its better idea to route and clip it behind the small chainring and into or inside the swingarm tube.. I dont know if i explain it very much.. Heres the pic.

On the driveside its hollow, nothing there i use a flashlight.. Its a sram gxp crank...
