Anyone know the formula, rule of thumb regarding the shrink fit tolerance
for fitting starter rings to flywheels? My feeling is to leave the recess on
the flywheel 'up' by say 0.010" (.25mm) so as the starter ring cools it
'nips' up, without too much stress on the ring but with enough 'nip' so as
not to work loose or spin.
