[Healeys] rear hub

[BJ8Healeys]

No, Bob, I haven't checked it.  I haven't had any reason to take the rear
hubs apart since I put them together in February 2002 and about 60K miles
ago.  I suppose if a bearing isn't bottomed out in its hole then
theoretically it might move inward; but with everything buttoned up I don't
see any loads on the spacer/bearing to make it move inward.  Anyway, I don't
have any oil leaks.  I think the spacer's function is, as you say, to load
the outer race of the bearing to keep it from spinning and that function is
calculated to work with the specified dimensions, otherwise the instructions
would say to bottom out the bearing in its hole and the dimension would be
whatever it would be, since spacers are not of various thicknesses like
shims.
I don't believe the spacer would be very effective in preventing oil leaks
to the brake shoes.

Steve,

As I understand it, the purpose of the bearing spacer is to capture/squeeze
the outer race of the bearing between the hub's shoulder and the
spacer/axle; to prevent the outer race from spinning in the bore.

Have you rechecked the height of the spacer after putting everything
together or after some driving time?  Just wondering if the bearing might
shift inward reducing the height.

I guess that the spacer is also the first "seal" to prevent the rear axle's
gear oil from reaching the brake shoes.

Cheers,
