A833 O/D gears in an A833 1:1 ?

Dave,

If you go the 307 bearing route (nothing wrong with that) use the max 307 bearing front and rear. My part number is M6307N. It has the max number of balls that can fit between the inner and outer races. Some say do NOT use a max bearing because the the cut of the gears, under acceleration and deceleration, you could spit a ball because of the way the bearings have a notch in the races to fit all the balls when they make them. The balls are spaced by a steel "separator" and will NOT spit out. They will if they are completely worn out, but so will any ball type bearing. Muncie's came stock with a max input bearing.

Of course, the max bearings cost more, but the "stock rebuilder bearings" don't last as long. You get what you pay for. On American 3 speeds, 4 speeds and truck trannys I don't even give my customers a choice. The max bearing is what I use, period. I want my units to last and keep customers happy.

Russ.
