[Mgs] Follow up to MGA 1600 MkII front end suspension suspense

[PaulHunt73]

If the oil seal collar fits on the stub axle and the oil seal itself is pressed into the hub, as on the MGB, then the spacer has to butt up against the inner race of the bearing.  Anything else would mean the oil seal or the outer race would have to rotate inside the hub.

I don't know whether this http://www.mgexp.com/article/mgb/mg-midget-wheel-bearings/bad-midget-wire-wheel-hub.jpg is any help but it describes how what seems to be a similar problem can occur on the Midget which has fully assembled ball bearings instead of tapered rollers.  Replacement hubs have a radius where the inner race of the outer bearing butts up against a shoulder, which holds the bearing further out than it should be.  The spacer is loose, but everything else is 'tight' as it is the bearings themselves that are taking any force applied to the nut and will fail prematurely.  As long as the nut is not tightened you could still achieve the .002 to .004 (same as the MGB it seems) end float on the bearings, but at the expense of having the bearing inners free to move on the stub axle and loss of strength in the axle itself.  Steering would be fine.  Ironically there are more than a few that opine this is the best way to set up MGB front wheel bearings!

  Yes, I think all three of us are singing in harmony. Both sides on my A were missing the oil seal spacer. From looking at the drawing in the workbook, and not having my spacer yet, it appears that that spacer fits in the inner diameter of the oil seal and butts up against the brake adapter plate and the inner bearing bearing (can't tell if it is the inner or outer race). I am really surprised that I don't have significant damage with the oil seal spacer missing: I would have thought the steering would be really bad.
