I have a Lecomble & Schmitt drive for my
autopilot. Owners manual doesn’t 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?
Thanks Brett
