[Healeys] Need help with O/D disassembly

[David Nock British Car Specialists]

Did you by any chance take a pressure reading prior to disassembly. You
probably will not see any problem with the clutch. They rarely cause a
problem. Mostar likely you had low pressure. The other thing that can cause
the same symptom is the clutch slave hose collapses on the inside and will act
like a slipping clutch.

was the only thing there to transmit the power.  In that case it could be
expected to slip.
