Suntour accushift 7-speed bar-con friction questions
Background: I just picked up a pair of used ones to go on a C & V roadbike in friction-only mode. They were black and I decided to buff them bright, so stripped off the anodizing with easy off (painted on the shifter levers with a chip brush, not dipped or anything). As many here know, those shifters do not come apart fully like the older Suntour bar-cons.
I neutralized and rinsed out the lye solution and used WD-40 for water displacement, and Breakfree CLP for lubrication.
I reassembled the right hand shifter and found that it does not give the micro-ratchet action I've read about - it either has 7 speed indexing, or a smooth friction feel, but with lots of slop- say 1/8 inch at the upper end.
Is this shifter worn out? Did I hose the mechanism with my anodizing stripping foolishness?
The non-switcheable left hand one for the chainrings has no real slop, and a slight ratchet feel on up-shifting.
