I do not know if I should replace the bearing and seal that is in the case to the right side. It looks good but I don't know.
Replace it! no point in taking the risk...tiny metal shards prob ended up lodged in there!
for the price and how much extra work it is from this point far outweighs the price of having to do it 2 hours after you put the bike back together!
This can be done with no specialist tools.... BUT ALOT of attention.. Heat the case to 200c (use spit test) and freeze the bearings for an hour, cold bearings should drop straight into a hot case with no need for a press, make sure they drop in straight tho.. For instructions look to you tube.
Do not put it back together without replacing the bottom end bearings, its just not worth it and i'd hate to see you have to do all this again!
