Started attaching my new pedals, but couldn't get the old left one off. Right is fine, but left's seized solid. Yes, I do remember it's a l/h thread. Enlisted Friendly Builder (supplier of damp-proof membrane for mud flaps "Take as much as you want, the landlord's paid for it"!) as he, unlike me, has muscles. No go. Not surprising as I remember when trying to remove it for packing to ship it, FiL, who must definitely has Muscles, couldn't do it either. In fact we've (all three of us, I'm reckoning) ranted off the edges of the axle. So it's soaking with WD40 for a few hours till a pair of mole grips can hopefully do it. Well, they've been on there 13 years so whatever grease they were assembled with, if any, has probably all evaporated.
