Bearing Size New Departure front hub Model M

[MotoDoc]

Can anyone out there tell me the correct bearing ball size on a New Departure Model M 36 hole front hub without oiler port. Are these supposed to be caged type or loose? Any help would be appreciated.
Thanks

Maybe this will help. Check out post #5. They call the ball retainers model M20. https://thecabe.com/forum/threads/new-departure-front-hub-question.24595/.

Somewhere I've seen a bearing guide for all brands but I'm having trouble finding it again.

Thanks for that great resource! This #20 bearing retainer looks promising though it has 7 bearings and the illustration shows 6. I wish I had taken photos of mine last time I had it apart for a lube. https://rustybicycleshop.com/20-retainer-bearing-7x1-4x1-1-8/.

The bearing listing in my Wald catalog has only one with 6 balls. They are 7/32 inch and the bearing is a number 7. I measured one and the outside diameter of the retainer appears to be 13/16 inch. This information may or may not be helpful.

Gordon: Think you are on the right track, took some loose balls and 3/16th's are definitely too small and 1/4 seems too large, have to get my hands on some 7/32nds to try. Thanks everyone for there help.
