1976.0. "How many bearings?" by CXCAD::KGIBSON (Ken Gibson CXO Disk Engineering) Thu Jun 20 1991 11:22

    When I first learned how to rebuild hubs about 15 years ago, I learned
    that the way to pack the bearings was to put them in side by side and
    then leave one bearing width empty space in the bearing cup.  I've
    always done it this way and it has worked fine.
    
    However, one of the guys that I race with was saying that you should
    pack the bearing cup completly full and that this is the way that Campy
    hubs are built at the factory.
    
    Any comments?

	My comments is that I put in the number and size of bearings that I took out. -john

	Re .1 >My comments is that I put in the number and size of bearings >that I took out. Which in my case is often 10 one side, 11 the other, goddammit I'm SURE I didn't drop any.... ;-) More seriously, I usually find that there's about half a bearing space left when I've put the last one in. I think that would be the ideal that the manufacturer is aiming for. Chris
1976.3	no space for me	VOGON::REEVE	Underground boring specialist	`Fri Jun 21 1991 05:02`	10
	I've always understood the resommendation to be that you should pack as many of the right sized bearings into the cup as possible. This even extends to throwing out the retaining bracket, if there is one, so you can fit in an extra bearing or two. Basically, the more the merrier, within reason! Tim P.S. I have no mechanical engineering degree. P.P.S. I don't know if right-sized bearings are eligible for early retirement.
