I just ground a slight groove/channel starting at the edge of the hole (on the inside of the bushing surface obviously) and went along about 90 degrees along the inner surface. I did this in both directions. My goal was to ensure decent pentration of oil aroiund the shaft. I do not know if it will help (or is even needed) now that I have new shafts and bronze bushings. It cant hurt.
My old shafts were severly galled and one tensioner was actually siezed to the shaft. The car I bought had sat for long periods in it's life. My guess is that over long periods of time,the oil runs off the shaft and condensation corrodes the shaft/arm. At startup the corrosion abrades the shaft and arm. After enough of these cycles the shaft galls and tensioner fails.
