update
Did not have a chance to have the tests suggested by Plane41 above, the mechanic in Ft Lauderdale went to do it - but then told me his jacks wouldn't work. Will try that t-shooting suggestion out in next week or so.
As for mule pressure, we took pressure down on mule to match the service manual numbers and system worked liked a champ.
They then had me check both pumps on the ground as follows:
-start front engine and push handle down, it should kick back up to neutral after pressure builds -- it did
- shut down front engine and start rear engine for same test -- it also passed
The whole system works like a champ on putting the gear down and locking it, which the service manual says is the same pressure.
Leaking actuator sound plausible - any suggestions for how to identify which one (note we did not see any leaks on examination when on the jacks and using the mule). Also, any suggestions for getting one (or all of them) overhauled? Is this something any mechanic can do, or should be sent off? Can they be removed and replacd without jacking up the aircraft?
