I'm restoring a vintage Peugeot with cottered cranks. When reattaching the cranks to the bottom bracket spindle, should I grease the pins or put them in dry?

  • The answer will be along the lines of installing a crankset on a square-taper spindle - to grease or not to grease... I've heard compelling arguments for and against.

  • Yes, first get them clean and burr-free (and also make sure the flat is burr-free), then a light coating of oil or grease. Apr 19, 2013 at 14:56

Yes. The grease will aid in installation as well as later removal.
