Can't remove 2003 105 Octalink Crank arms.(9 posts)

Can't remove 2003 105 Octalink Crank arms.niteschaos

I need to remove my crank arms and I can't seem to get them off. I don't want to risk stripping them since they are only 4 weeks old. I have the new crank arm remover for the new "oversized" axle (that's what the back of the Park tool package said as the older Park tool crank arm remover for square tapered spindles didn't remove the arms). It looks like there is white locktite holding the arm to the spindle. How do I get the crank arm off? Should I try penetrating oil then force the mutha or what? My shop won't be able to fix my bike for a week due to business being really busy and I don't want a creaking BB for another week. It's driving me nutts. I already have the propper BB tool for removing/installing/tightening and the crank arm remover (CCP-4 from park tool).

... so I'm guessing that your crankarms don't have the single release fixing bolt caps installed?

... if the caps are installed, an allen key can be used to easily remove the arms.

... if you don't have caps, or have removed them... you'll still need to remove the fixing bolt before using the Park tool.

I doubt that anyone would have used any form of Loctite... you're probably seeing grease.

Once the tool is threaded (see instructions above)... removal should be easy (easier than many square taper types).

Be the bike.
but removal is hard, that is why I'm posting.niteschaos

no kidding you have to remove the screw. The only reason why I'm posting is that I'm afraid that the force required to remove the crank arms will also strip them. They aren't coming off more easily than my square taper arms.
... could it be a matter of leverage?Akirasho

I'm still unclear... have you removed the fixing bolt??? Are you afraid that your Park tool will strip the crankarms... or are you afraid of stripping the spindle???

... dunno what kind of leverage your tools afford you... but you might consider applying a breaker...

Be the bike.

make sure it is all the way screwed in with a wrench and then tighten the arm till it stops and tap the arm with hammer clock-wise. It will come off.

That white stuff is probally dry grease.
Okay, so the consensus is to use a hammer.niteschaos

Okay. Thanks for the advice all who replied. It looks like I'm gonna have to really goose that mutha off the BB.

You may want to put a thin block of wood on the crank arm before you stike it with a hammer to avoid dinging your crank arms. I suggest applying heavy force to the extractor, then tapping as suggested above on both sides of the arm. The arm should move, if not tighen again slightly and then repeat until the arm comes off....Let us know how this works out for you!
Rubber/plastic hammerLC

Rubber/plastic hammer works best. Tap both the extactor as if turning it, and the inside of the arm.

I'd like to thank all for helping my get access to my BB so I could quiet my investment and make it sound like the fine tuned machine she is. Thanks and take care!
