My bottom bracket is not letting the cranks spin as freely as it should (without the chain on) so I think it is time to replace it. As it happens I have one but I have a couple of questions with the install.
There is a sort of dust cap/O rings from memory on the crank side that goes against the bottom bracket bearings. The new BB didnt come with this and I would like to put a new one on. Does anyone know what the part number/name of this is or where I can get one? Also do I really need it? All the online install videos I have seen never seem to have one.
Also last time I installed a BB I tightened it with a wrench but didnt check the torque. Any cheap tools to make sure I am getting the requred torque when tightening it up?
