I would like to remove the bottom bracket from an old french peugeot race frame. I believe the frame was built in 79 judging by the decals and stamp on the bb.
The bottom bracket and spindle at the moment will spin, but feel very dirty and sounds gritting so I want to take it apart to clean/regrease.
I'm almost certain its a french bb and not swiss based on the info on from cyclespeugeot.com.
I'm about ready to start this but have a few questions.
- From what I have read, I only need to remove the left adjustable cup to service the BB?
- The left adjustable cup will be left threaded so will need to turn clockwise to undo?
- Is the lock ring also left threaded? It has an outer diameter of 47mm and i'm currently struggling to find a locking ring tool to fit.
I'm trying todo this properly as it seems getting a new or used french bb is not going to be worth it and I might as well get another frame.
If it helps, here are a couple of pictures:
