As mentioned/suspected, it is a heat treating issue, which I confirmed with Speeco this morning. Basically the repair consists of replacing the rack with a better one which means basically taking out a bolt so even if a shop has never seen a kinetic splitter they should be able to handle the repair. On a side note, I was told none of the new racks were available yet so Speeco does not know what time frame the reapir will be completed in.
Hint of advice for all those owners, I recommend taking the pusher off the beam and adding some loc-tite to the 4 little screws that hold the brass wear-strip on. Mine came loose and one cycle sheared 3 off and dug one into the wear-strip on the beam and seized the unit (took a sledge to get it unlocked). It was replaced quickly by speeco, but I added loc-tite to the new one and actually drilled/tapped some new, bigger holes in the old one.
I will let all know when my rack arrives so people have an idea as to when the repairs will begin.
On a side note, I have obtained parts directly from speeco to do work myself although this will not be the case for this problem because they are going to, through the repair shops, keep track of which units are repaired.
