I recently stripped a front hub (1991 XT) and rather shamefacedly (as I'd serviced it last) found
that one side had 10 ballbearings and the other 11. Oh well, I thought, there's space for 11 I'll
replace with 11 - and the new ones came in packs of 22. However.....even more recently I've stripped
the hubs of my childrens trailer for the first time (Shimano Acera) and all four sets of balls
number 10 although, again, there is space for 11. As these were supplied like this I assumed it was
correct. A visit to Shimano's site also indicates 10 for Acera front hubs. Just to be sure I checked
Sheldon's site (see, I'm getting the hang of this now) and he says "most front hubs" take 10 balls.
So I re-stripped the XT hub and removed 1 ball from each side thankful to have found my error soon
enough to prevent any damage. And then.... today, flicking through an old Cycling+, I came across
their "workshop" article on hub servicing. You have, of course, guessed that it says "use 11 3/16
bearings in most front hubs". Anyone know the right number for "most front hubs" and more especially
for a 1991 XT (Hub M730)? The only thing I'm sure of now is that 11 one side and 10 the other is
definitely not right. Thanks in advance, tony R.
