Typical, and probably a case of lack of maintenance but I have barely ridden the full sus over the winter...I have noticed the BB getting a little graunchy and have been meaning to get it replaced.
Anyway. I cleaned the bike this afternoon as I am off to CyB at the weekend for a good friend's stag-do.
I noticed that there is a small amount of play in the crank, and it looks like the bearings are completely borked.
I tried to remove the crank to investigate further, but the crank will not come off. It is an XT HTII crank. I have removed the non-drive side crank arm & it looks like the plastic BB part that the crank passes through on the non-drive side has seized onto the crank axle.
So far I have tried:
pushing the axle from the non-drive side,
pulling the crank from the drive side,
whacking the end of the axle from the non-drive side with a rubber mallet,
laying the bike down with some raised blocks beneath the end of the axle and pushing the frame down using a decent amount of bodyweight.
It is getting to the point where I am scared I will damage the frame if I use any more force than I currently am.
I will probably call my LBS tomorrow & see if I can get the bike into them, but I won't be able to do this until Tuesday morning. Then, they might be too busy to try to sort it out & even if they have the time they might not be able to get hold of the particular BB that is needed (BB91-42A)....
Balls. Balls Balls. Should have cleaned the bike last weekend when I wanted to, rather than arse around with gardening & stuff. Ball Balls Balls......
Any ideas greatly appreciated.
