I have Todd Down's book "Bicycle Repair and Maintenance." He says the rear Derailler should be removed, and the outside grit cleaned off with diesel fuel. I used kerosene. I brushed off the grit - I did not soak it.
I am going to relube all pivot points with Tri-Flow. The main spring in the knuckle(?) housing was coated with a clearish grease. Do I need to regrease that spring, or can I just coat it with Tri-Flow? All I have is axel grease, and it seems that that would attract grit.
In other words, I cleaned the derailler without disassembling it. How should I relube it?
