Hi Ron: I'm sorry, I thought I read in your first message that the rudder
bell crank on the control mast had some play
I refer to the control mast as the assembly behind
the seat which has bell cranks for the rudder and the ailerons, the control
column is the assembly under the fuselage tank.
Yes, there should be no play between the center
shaft and the outside tube of the control column. As Hartmut (or someone else)
said, the bushings should be oiled every annual, and I believe the maintenance
manual says every 25 hours. I indicated that you needed two people to properly
check out the control system (after you get the weight safely off the nose
wheel). With you inside, have someone else move the nose wheel slowly and only a
little at a time, left and right. You need to observe the controls starting with
the rod ends on the bottom of the control column and work your way up to the
control wheel to see where the play or binding is located. You also need to
check the nose gear end of the steering mechanism for any and all play.
As others have said, you may find this is all OK,
and the problem is elsewhere, but you have already indicated there is some play
in the control column between the inner shaft and outer housing. I suspect you
will find several places that there is play ( the nose wheel moves left and
right and the controls do not)
Good luck in your search and please let us know
what you find is the problem. It could be something we have not thought of or
seen, and we all want to know about it.
Lynn
