Xt Is this Crank fully seated?
 
I was trying to remove this craink on my Giant hybrid with the Park tool and it wouldnt budge. I noticed the bracket cartridge male shaft square key had a gap of 1/8 inch in the crank female square shaft. I checjec th druve side and it was the same way, So I guess thats thd way it is, or is it?
Jusf seems the crank is flush with the bracket on m uhh other bikes.
Funny thjng is I have had this bike 3 years and never noticed this.

How far into the crank arm tapered hole does the axle go? What's the torque you used for the retaining bolt? Andy

Thanks for your help. I will post a picture tomorrow showing what's underneath the edge bolt on both the drive side and non drive side. They actually match!
Insofar as torque is concerned you're talking to a guy who shears automotive bolts. Recognizing I an working on bikes now, I tried a bit hard, but I knew when to stop.

I googled my bike -- a Toughroad- and I found a picture showing there is a gap.

The important issue isn't how much of the taper is visible, but rather how the arm is seated on the spindle:

I am still wondeing.Trouble is I cant even budge it so I can inspect the inside geometry to see if its fully seated. Its on there tight and the Park tool wont budge it.

Check carefully to be sure there isn't a washer at the bottom of the crank's extractor opening. If there is it will prevent the extractor from working.

The classic trick with a too tight cotterless arm is to leave the retaining bolt a tad loose and go ride the bike. In time the arm will migrate off the axle and the still there bolt will prevent real damage. Andy
