After ten years in service,
all three door cylinders and two of the three gear retract cylinders on my 320
were 'weeping' fluid and needed rebuilding (Bill Harrellson said that his have
been in service ten years with no sign of leaking and that mine are
leaking because I'm not flying enough - he's probably right)
The three gear retract cylinders are
manufactured by Wolstenholme Industries and neither I nor a couple of
A&P's could determine how to remove the snap rings at each end.
Eventually I saw how. Simply remove the hose fittings at each end and press the
end caps a short distance into the cylinder to expose the snap
rings and they're then easily removed.
