Patriot shaft mount roller problem While tightening one of the small (1/4"?) bolts on the patriot shaft, the shaft split in half. It must have been a stress fracture in the shaft or something.
It looks like I can just take the rockers off if I have a new shaft? Since the motor was not even fired or even rotated, this has got to be warranty issue, right? I don't really want to return the whole set since I have one bank already installed.

They were installed by an ASE Master mechanic and race engine builder. They were installed with the valves closed, and actually snapped with no one even touching them.
It does get a little more interesting though... We took off the driver's side rollers, and as they were removing them, another shaft broke.

Those shaft mounts I believe are made by DRE. They are very similar to the ones Comp had offered for a while. I had a set and snapped one too. But I snapped mine due to being in a rush and I forgot to turn the motor over to get the cam on the base circle and I was using 1.550 springs with 200 lbs seat presure and 650 open. It snapped it like a twig. Those shafts are not that strong. But...if you are shure to install them correctly you should not have a problem. You must have the lifters riding the cam on the base circle COMPLETELY. DO each set of two at one time. Spin the motor over to get it on the base circle. Then as you are tightening....tighten evenly on all three bolts a little at a time. Or...back off the adjusting nut all the way out.
