Hi Herb
I too found what I consider excessive play in my trim tab actuator, not as much movement as you have but enough for me to think that this may cause some elevator movement during flight (just an opinion). I looked for new (never found out the cost) and when not available found a secondhand unit that was almost new.
When I took the threaded rod out of the unit I just recieved and fitted it to my actuator all excessive play was gone, I then fitted my rod into the S/H actuator and there was the play. So it may only be the threaded rod.
I then fitted the second hand actuator and it's rod into my plane, no movement and new PN3A bearings to finish the task.
Second hand actuators and rods are not easy to locate, mine was by pure chance.
On ebay there are a number C337 parts for sale from airtransport, he is parting out a P337 and may have an actuator and threaded rod, providing they continued to use the same parts through to the G model. Sorry can't check that at the moment as I am currently O/S, again!
Hope this helps
Dave
