Come on guys. If it has a little visible ball in the top center. Its a grease zerk fitting. If it is hollow in top center, it is a bleeder port like your trailer or car brakes. I think. I have been wrong many times before. LOL

Having been aviation for 22 years, worked on fixed wing and helos, both flight line and component repair, I have NEVER seen a actuator need grease on the top of the piston.

The actuator shown is a simple two way acuator the has a o-ring around the piston and it gets lubricated via the oil/Hydraulic fliud used in operating the device. It is a grease fitting for the bearing, that may have been there before under original design.

I'm thinking it was a bleeder and somebody for some reason screwed a zerk fitting in it. Needed something to plug the hole to go boating for the afternoon and never got replaced. Possible? Not that I would ever do that. Doug

Sorry but both of them are like that and this is a race boat so it wasn't like they didn't know they were going to take a ride at a certain time.

I know it doesnt need grease at the top of the piston with hyd fluid. I just didnt think it was going up to the hinge pin. I am sure we are looking at a proto type or a engineering oversite.

I have and work on mech and hyd punch presses that over 70 yrs old. The way the equipment was over built then to what it is now dont even compare to each other.

Is this how they debate over $10,000 toilets in congress? Now I know why nothing seems to change within our government.
