installing a liberty gear 26 spline input shaft. my problem is that the bearing race for the input shaft bearing is loose and rotating in the cup of the front cover, isin't the race supposed to be tight and not move, thinking maybe I messed the cup up taking the race out to put the shim in and now it's wore out as I can put it in by hand and it rotates which can't be good. thinking i may need a new front cover, any inputs as the race should be pressed in shouldn't it?
