Jager, thanks for the feedback, and link, [Brad has got an incredible wealth of info. He continuously amazes me.] Tell me, did you use a standard .5" OD [I measure .505, or 12.8mm inside the shaft]x .312 ID seal in the end of the shaft? .312 is a little tight for the pushrod [8mm=.314] but it could work if it sees a little oil to keep it lubed. As far as the internal caged bearing, I'm thinking that as long as you watch/lubricate the preasure plate bearing, the pushrod should never move, so why need a internal support bearing? What's your view?
Thanks
