Keith,
Bob's 20B crank separation tool is just a 1" thick steel plate with a
hole in one end large enough for a 3/4" threaded rod to pass through.
The threaded rod is screwed into the hole in the lobe on the crank. You
then pass the threaded rod through the metal plate which is positioned
so it rests on the end of the crank (pulley bolt installed). You then
screw a nut down a little past flush, so that the opposite end of the
metal plate is slightly higher on the free end. One or two stiff whacks
with a large hammer on the free end of the metal plate and the crank
separates. Basically, its just a fulcrum device. The most difficult
part is threading the rod to match the threads in the crank journal.
This sounds more difficult than it really is, but it works great.
