Every part has allowable manufacturing tolerance specified on the print.
=20
I believe the brake discs should be about 1/2" thick but I don't know =
the
tolerance for the max thickness or the diameter.  The caliper opening,
caliper position and the thickness of the brake pads govern the max
thickness and diameter of the disc.
=20
The hub could be a different story.   It is very possible the mould =
cavity
for that hub was at end of life with the tolerances maxed out or even
greater.   Rootes was also near end of life so a deviation was probably
signed off to accept these out of spec parts.  This is only a possible
explanation.   We would need Corporate record to know the real truth.
=20
Most likely that hub has some extra metal at the center hub that can be
machine down to fit that Mag.

The disc thickness will be weak, the size if disc is odd.  Should be =
same
diameter on series 3-v alpine and tiger.

As for hubs same on all alpines on front.... Maybe running wrong grease =
cap?

Hello All:

The other day, a friend who owns a Tiger II found that one of his pie =
mags
would not=20
fit on one of the front hubs. In trying to figure out why, we took a hub =
off
a Series V
Alpine that we have been dismantling and found that the mag would fit on
that hub
very easily. I would have thought that the hubs used on the Tiger II's =
and
the Series V
Alpines were the same and, as far as I can find, there is only one part
number on the
Parts List, but they are slightly different. Can anyone offer any =
insight
into this situation?

We also noticed that the brake discs on the Tiger II and the Alpine V =
were
different, with
the Tiger disc being thicker but slightly smaller in diameter than those =
on
the Alpine.

Are these just ordinary variations in manufactured parts of is there =
some
other
explanation?

Thanks,

Tod
