As it turns out, both Bonney and Snap-On make wrenches and sockets like this.
Assuming, of course, Bonney is still in business. I do have one of their
torque wrenches, but that was purchased a number of years ago.
And regarding the question about the GT6 hub bearings, here's another lame
ASCII explanation. This may or may not be the actual arrangement in a GT6 hub,
I haven't looked for a while. But it is typical of tapered roller bearings,
even if it does ignore certain aspects of a driven hub on a tapered axle.
Hopefully the way to shim bearings is evident.
Bearing parts:
Shim Outer race Rollers & inner race
I XXXXX // X
I XXXX // XX
I XXX // XXX
I XX // XXXX
========
________ ========
| Stub Axle
+--------------
Now, we put them all together, and get an assembled axle, shim and bearing
setup.
A
##IXXXXX // X # = Hub where outer race seats
##IXXXX // XX
##IXXX // XXX
##IXX // XXXX
________I========NN N = Nut holding bearing/hub to axle
|I========NN
+---------NN
B NN
Adding shims at A, between the hub and the outer race will move the outer
race closer to the rollers, reducing endfloat. Adding shims at B, where the
outer race seats, will move the outer bearing away from the inner race,
increasing endfloat.
