Hi, I hope its OK to slightly hijack this post; I don't think I am going off topic.
My question is, should I follow the same dunk, spin, oil procedure for these 2 wheel/pulley thingies off an old and very weird derailleur (BGA Velectrik) I am cleaning.
....or can they be non-destructively dissasembled for greasing?
Predictably the morningstar grease didn't get to the bearings, Would Chain-L be a good choice for oil (it may be too thick to spin-and-lube; so maybe just lube the gap and wait for it to soak in, then spin, then repeat)?
if you are curious, I am detailing the strip, clean, rebuild of this bike
here.
