[img]cid:image001.gif(at)01C91280.44B53550[/img] <![endif]-->
This “highly recommended” mod is simplicity itself to install except for what we colonials would refer to as typical English understatement, when the procedure says to “remove the pin which locates into the friction plate” without any suggestion as to how to accomplish this.
First, having assumed that a lack of guidance meant that the pin is easily removed, I tried to grip the pin with my fingers. OK, so the pin fits a bit snugly. Next I tried ordinary pliers. No success. Time to bring on the heavy lifting equipment in the form of those old reliable Vice-Grip pliers. Hmmm, that managed to damage the pin but it is still firmly in place.
Now it was time to get a bit clever, so I drilled a hole in the pin and tapped it, put a stainless steel screw into the hole and pulled on it. Nothing moved, so it was time to start using some brute force, a jack screw. I fabricated a short tube that I put over the pin and used the screw to pull the pin against closed end of the tube. The screw broke. OK, no problem, just put a nut onto the screw to do the same thing. That pulled the remaining length of the screw out of the hole, stripping the threads in the pin which had still not moved one micron.
With nothing left on which to grip the pin I finally got smart and fabricated a spacer to cover the pin.
These Mods are such fun!

Hi Rob,
I know what you mean about trying to remove the pin that locates the the friction plate since I had to remove it to do a completely different job. I am rather confused however since in the instructions for Mod 59 that I followed there is no requirement to remove this pin anyway. In fact for the friction damper to continue working correctly this pin must most definitely remain in place.
Somewhat confused by your question

Pete:
It was not a question, but a “heads up” to others who may find the pin difficult to remove. The procedure http://www.europa-aircraft.biz/pdfs/modifications/Mod%2059.pdf involves using a spacer ring to push the bushing upward, in order to make room for the o-ring, by using the nose gear fork assembly as a pusher. In performing this operation that infamous pin would otherwise be in the way so is must be dealt with in some fashion. Covering the pin turned out to be much easier than removing it.
And, yes, the pin is required in order for the shimmy damper to actually damp.

Hi Rob,
I Just put the spacer ring on top of the plastic friction disc (still fitted over the offending pin) and the pulled the bush up into its new position. Done !!
Best regards

After seeing how little force (virtually none) was required to move the bushings it was clear that leaving the disc in place would have been fine. Too bad I didn’t think of that at the time.
