Hello Kenny,
I noticed your question to the Healey list.
If you wish to observe if the pump plunger is actually working, drain the
oil from the overdrive unit by removing the large brass nut underneath,
remove the gauze filter and also the setscrew, this will enable you to
remove the centre nut with a small socket. With the aid of a good flashlight
or lead light turn the rear wheels so it turns over the overdrive internals,
if the pump is located correctly onto the operating cam you will observe the
pump plunger moving up and down. If not then there may be a good chance that
during the re-assembly you did not pull the pump plunger down with a draw
wire to enable the pump plunger to locate under the operating cam and as
such the pump plunger shaft will be bent and is unfortunately buggered.
I hope that this helps you to solve your problem.
Regards.
David.
