Just curious but how much pressure / suction would rotating the rotor system backwards at 2-3 rpm max generate?
Never saw any crap on a hydraulic filter except once when the fluid in a system somehow got contaminated…we never did figure out how the contamination occurred. Discovered by the engineer during his evening DI. fluid was an opaque yellow colour instead of the expected clear Cherry Jello red.
System flushed, filter replaced ect. never happened again. Strange.
