Changers,

Check out my newest guide to understanding the CJ-6 pneumatic system in
detail. It's in the RPA Store, under Manuals.

Can anyone answer the following ... does the oil pump have a failure mode such
that if the inlet oil to the pump runs out / line fails and there's no tank oil
, it stops the scavenge pump sending the oil out of the engine to the tank ,
and rather cycles the oil internally ? Just looking at the schematic and not
having disassembled a pump - it appears there is a gallery joining the scavenge
side to the pressure side with a spring / valve arrangement - separate to the
pressure regulator ? It seems that if the input pressure drops , due to say
no oil in the input line , the scavenge side redirects oil to the pressure side
creating a closed loop to prevent engine seizure - as it uses what's in the
sump etc ... is this correct or am I deluding myself that an engineer might have
actually designed a failsafe this way ? Thanks , matt
