Prw stainless rockers
I've been working on a set of PRW stainless rockers this week getting them clean of debris, deburred from sharp edges and spaced properly above the valves.
One thing is for sure, you cannot / should not, of course install these things straight out of the box without a very close inspection (and cleanup).
I also had one rocker that showed ugly machining/handling on their bearingsurface. But I was able to clean it up.
I lightly polished the rockershafts as the coat of rust-prohibitive oil had left residue stains on the shafts.
Had to shorten the (very soft) rockershaft bolts almost 1/2" as they bottomed out before the holddowns clamped down the rocker shaft.
Polished and dressed the edges of the rocker bearings as they were very sharp.
Deburred both oilholes in each rocker.
Cleaned the adjusters, and deburred and smoothed the cup area.
Cleaned everything throroughly with brakecleaner and air and reoiled all the moving parts.
Had to grind down some of the thick rocker spacer rings slightly to give them some minor side-to-side movement.
Still have my doubts about the adjusters strength and thread engagement in the rockers. Also found different shaped/height lock nuts on the adjusters.
I will most likely replace all the adjusters if I can find better ones here locally.
