    Default rebuilding roller rockers

    I've got this set of crane gold roller rockers that I pulled out of the drawer and they felt a little rough...like they had some dirt in them....so I took them all apart and cleaned all the needles/trunions etc...

    I'm seeing some wear on the trunions, but only over about 120° of it that is loaded against the bearing. I'm not sure if I can still order replacement trunions...I heard crane shut the doors and their phones seem to be disconnected. Would it be unheard of to mill or grind a new flat on the other side of the trunion for the polylock to seat against and simply flip the trunion over so that it's got a good loaded bearing surface? Otherwise, these are in great shape. I'd hate to throw them away...he trunions are huge compared to the comps that I have.

    Edit: Just got an email back from Crane, they do not sell replacement parts for their rockers, and they said " We do not recommend rebuilding due to the design of the body-bearing press fit." WTF, didn't they rebuild these in the past? I coulda swore they did.

    I have stuck new bearings in Iskys before. Same bearing as Crower Enduro SS rockers. But I don't know if I would put a flat cut on the opposite side if the trunion. PVS rockers and some others are flat on both sides. But the Crane trunion is pretty whimpey compared PVS or Iskys and Crower SS.

    Translation: We didn't make enough $$ for the hassle of providing the customer service of rebuilding or rockers. We prefer you simply buy new ones as that is much more convenient and profitable for us, which is all that really matters....

    Exactly. Unfortunatly for them, due to their decision to not provide service parts for their products, I will be shopping elsewhere should I need a new set of rockers.
