Mea Culpa, Bill! I did not realize that twin-cams had taper roller bearings in
the front hubs. My apologies for the erroneous criticism.
(However, I still stick to my belief that leaving the design the way the
factory intended is the more prudent course of action - unless one is
substituting a design which modern technology proves to be better than the
factory could manage at the time the car was built.)

Indeed, MGAs don't call for shims because they use ball bearings

my opinion based on 25 years as a professional MG mechanic) you really

be better off with the spacer between the two roller bearings as,
otherwise,
the inner races have less support than the factory designed them to
have).
However, this whole discussion began with a question about how to
properly
set up an MGB front end. The MGB does not use ball bearings but has
roller
bearings riding on seats pressed into the hub. Without using the
spacer
between them and shimming for the correct preload, these bearings will
not
function as designed.
So, Bill, your dedication to preserving Twinkies and other antiquities
has
led you to pontificate about that which you are not fully
cognizant...............
Let's turn that around, Lawrie.
I think it may be you that is not cognisant of all the facts.
I race a Twincam.
Twincams have taper roller bearings, not ball bearings like all other
MGAs.
In this they are the same as MGBs, and Triumphs.
So I believe that my comments were appropriate and well considered. It was
not pontification (in any event) and I believe that I (at least) WAS fully
cognisant of the relevant facts.
