I have a Lecomble & Schmitt drive for my autopilot
. Owners manual doesnít mention anything about frequency of hydraulic fluid change. So I emailed L & S - there response is only when leaking from pump
or power pack.
My thought would be to change out fluid every few years, as the fluid would more than likely be taking on some ambient moisture, which would deteriorate internals of pump
& power pack.
Just wondering what other owners are doing?
If you are changing oil
here in Australia
, what replacement fluid are you using?
