Complicated BB Installation Question/Problem
OK this might get long winded....i attempted to install an X-Type Race Face BB (External Bearing) onto my MTB today....I removed the stock Shimano Octalink with no problem....totally wiped the BB shell clean and regreased it. I installed the drive side BB cup into the frame no problem. Started screwing the non-drive side in and it wouldn't go in very easy....pulled it back out and tried again....went in a lot easier but not effortless...Pushed the left side crank arm on and then attached the right side with the crank arms.
The crankset didn't spin very well at all....would spin maybe one revolution and stop (with no chain attached). Started looking close at the BB cup on the non-drive side and noticed that the top of the Bearing-Cup was flush with the BB Shell but the bottom was about 1mm away from the BB shell. Major problem. So I pulled it all off and tried the left side BB Cup again and could not get it to line up flush on all sides of the shell.....what is the deal? Questions:
1. Could my BB threads be stripped out? If so is my frame worthless?
2. Does the fact that the cup is not in the shell square make the crank not spin freely?
Thanks for any help....as you can tell I am a little stressed.
