[Healeys] New clutch query

My first thought was that if you were having to force the gearbox when it
was 3 to 4 inches away from home, it may be the spines in the clutch disc
and the input shaft were causing some interference. This should have been
an easy slip fit. Did you lubricate the spines? Test fit the disc on the
input shaft? Installing a gearbox should not be a tedious affair. Or,
you did not get the disc properly aligned using the little plastic tool.
There is a lot of wiggle room for error. I've found that an old input
shaft works better than the plastic ones for getting good alignment.
That brings me to my next observation. If for some reason the clutch disc
is hanging up on the input shaft it will not disengage as smoothly as it
should. Is this your problem? It's not clear to me what you mean when you
say "difficult clutch".
I have never heard of any need to break-in a clutch.
