Recently got my bike out – in response to traffic increases, local road changes…and the nagging realisation that having a vehicle encourages you to drive everywhere
Anyway, among a bunch of ailments (seems to slip on the bag gear cog, doesn’t change gears reliably…) there’s a possibly serious one…
The central bearing started to grind and squeal a few weeks ago…I know they’re meant to be sealed units, but I got some silicone lubricant in there and it quietened down…but I’m not sure it’s going to last
So: do we have the tool(s) to open this up and replace the parts? And what tools/techniques do I need? I last worked on bikes when I was 14…so some of it may eventually come back to me…
TIA
