Pulling TD Brake Drums

[Mike Razor <mrazor@kih.net>]

Took the front tire off and now I need to pull the brake drum
off and replace the wheel cylinders.  Got the shop manual and
it is greek to me.  I also pulled that little cap off that
sits over the big castle nut and looked through the grease and
see a bunch of ball bearings.  On my MGA there are some screws
that hold the brake drum on, I don't see those on the TD.
Before I dump a bunch of ball bearings all over the garage
floor, How do I take the brake drum off.
THANKS!
