I need some help identifying the fsa bottom brackets model number and/or getting the correct installation sequence for it. I have a FSA Energy Megaexo crankset with bb that was purchased at RepartoCorse when it was on sale a while back. It was installed on another bike and removed by my LBS mechanic (so I am not sure the order the parts were installed). I installed the crankset on my Lemond but I want to make sure I got the installation sequence correctly.
I have the instruction sheet but FSA combines their installation diagrams with all the parts combinations of they offer. Also they do not include a diagram for the 8000 series bb that is suppose to go with this crankset. So unless you know the bottom bracket model number you don't know if you are suppose to have one or two O-Rings etc. I looked all over the center sleeve of the bb but couldn't find a model number. The bb has alloy cups with a black plastic center sleeve.
I only have one O-Ring so I am not sure whether it should be placed between the cup and the bb shell on the drive or non-drive side. Or am I just missing an O-Ring? If you have the same crankset and know the correct installation order or know where I can find the model number on my bb I would appreciate it. Thanks.
