Bottom bracket "alignment" question
Hello!
I've been hearing a clicking noise with a frequency comparable to my pedalling frequency. It's been driving me mad for a week now.
Thinking it was the seat, I removed the seat post, greased, etc., but the noise persisted.
I took a look at the bottom bracket (Shimano BB51) and noted it has a 2-3 mm play: I can push the crankset and the pedal at the other end will come out by 2-3 mm...
Since I am new to the forum I cannot yet post pictures, so I've had to upload it here imgur.com/a/9MnqA49 (the forum also does not allow to post URLs until one has 10 posts......)
Is the play room due to some washer/ring which vaporized or broke and fell? Is it a matter of tightening? If so, what? Should I just get a new BB51 and install it?
I am new to bike repairs, but am willing to spend the time and a bit of cash to get the material+tools and to learn (and I have another bike I can use while I horse around with this one). Any hints will be most welcome!
Many thanks in advance!
PS: a decent clean-up is long overdue....
