Dang Rocker Shafts Too Soft
Sometimes you take a chance and it does not pan out. We were replacing an erratic lifter last night and pulled the rockers to inspect and found this wear on the rockers shafts after approximately 1000 street miles. The needles are digging into the shafts big time; this pix is one of the worst areas, but they all show some wear and edges on the areas where the needles ride on the shaft.
The 'chance' here was some PRW AL rockers on eBay for $224. I saw them, and said "what the hey; let's see if we get away with it" LOL. These were leftovers from PRW (and shipped from the PRW address), and when received, looked to be broken sets put together into complete sets. Who knows what shafts got thrown in, but obviously they are nearly not up the required hardness. I have read that is a key factor in the success or failure of needle bearing rockers.
We got some Crane Gold 1.6 rockers on the way. They look to be discontinued but Jegs has some SBM 1.6 sets left. With the way that stock rockers run and last, you would think that custom rockers would be easy to make work well.....
