Electric trim servo tight fit

Status
Not open for further replies.
I just finished installing the servo motor to the 616PP cover plate using the 602B left and right brackets. It appears that the servo is contacting and pushing down on the shop head of the aft 2 rivets that hold the left and right brackets to the PP cover plate. Is this normal, or should there be a gap there? The screw and nut holding the servo down didn't come with any washers or spacers.

Installation

Also if I remember correctly I had to either run out the servo or retract it to get it to fit into the HS. Use a 9 volt battery and just switch polarity between extend or retract.
 
Yes, the servo is a tight fight - and there is a range of travel for the servo arm where it can be assembled, and a range where it can't. It's finicky - but it works well.
 
Thanks everyone. I'll squeeze those two aft rivets a bit tighter. Nice to get affirmation that I didn't screw up somewhere. I'll reach back out when I go to attach it to the elevator and trim tab regarding the arm travel calibration. Thank you!
 
You’re rivets look squeezed enough. Perhaps you have enough room to fit a washer or two between the servo mounting flange and the brackets.
 
One other thing to consider: When you mount the servo into the elevator, the forward part of the actuation arm can extend through the hole in the spar. Some builders route the servo's wires through that same hole, but I thought the risk of it contacting/chafing the wires was too high, so I made a separate hole (w/ snap bushing) for the wires.

Yeah, I made a separate hole for the wires too.
