Yesterday I wrote "I have concluded that the most likely cause of my problems 
are low OD fluid levels and/or inadequate opening of the actuating valve. Both 
I can  readily deal with."

In off line discussions with Steve Byers I have added a third and ominous 
possibility, a defective accumulator. The good hydraulic pressure already 
confirmed only indicates that the pump is OK because testing was not done while 
trying to engage the OD. My understanding is that OD engagement is the 
accumulator's function and the pump's role is to pressurise the accumulator for 
this task before OD engagement. A definitive test of accumulator condition 
seems to be how well it holds pressure after the engine is switched off!
