Oil Leak at Torque Tube socket.

[stuartu]

As you say, the oil may well be leaking via one of the holes in the torque tube ball. My Ulster will do this. What’s to stop it? One answer would be to ensure that the torque tube anchor is well greased. It can contain much more grease than you might consider reasonable. That’s what I did on the Ulster, which is now continent.
Crude perhaps but it works.

Regards,
