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

[Clayton Kirkwood]

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.

 

The 1500, 1600, and MkII don't use shims, only the twin cam and deluxe use
those because of different kinds of bearings, as I understand it. I did
however, buy spacers because of the extended space I seem to be running.
That may resolve itself with the various new parts.

Are you and Barney singing off the same hymn-sheet?  What Barney describes
sounds the same to me as the MGB - that is the inner races are held tightly
between a the oil seal collar on the inner part of the stub axle and the
clamping nut and washer, with spacer and shims between them.  Clamped like
that - to between 40 and 70 ft lb on the MGB at least - the inners can't
spin on the axle.  But I thought it had already been established that your
version of the MGA isn't like that anyway.

 

If the oil seal collar is missing, i.e. the part that the oil seal lip runs
on, then with the MGB system (again at least) you will never get correct
assembly of hub, bearings and axle as that takes up 1/4" or more of the
effective length of the stub axle and hence play in the assembly.

 

I also suggested that if the problem was only on one side, then carefully
dismantle the other and compare components and dimensions.

... I don't really understand why the inner races can be so relatively
loose. Because of the relative damage to the spindle, a noticeable wear on
one side of the spindle especially on the outer bearings,  I would think
that a slip fit inner race, even with axial compression, would allow
potential spinning on the spindle causing wear similar to what I am seeing.
