Am I doing it right?

Yes, I think so.
Well at last our problems with the remote control seem to be solved. 
Today we installed the repaired housing with cilinder and piping and tested it from the wheelhouse.
And: it worked!
The 2100 horsepower Werkspoor engine (built in 1951 and the only one in the world that's still in service) started and stopped and reversed as we ordered.
