Maybe others have the same issues with the outrigger mechanism on the Europa monowheel.

For retraction, the outrigger OR1 pivots around a AN4-21 bolt, which pivots within FL9 bushes in the two W21 plates. Thus, the entire pivot mechanism is on two small bushes, the FL9s. Imagine the bashing these things get, especially on rough runways, and also the sideways dragging/pressure against them when you have to spin the Europa around to backtrack a runway. I am finding that I have to replace the FL9s every 300 landings or so, with the rough runways (murram, stones, coral) we have here. Is is not possible to beef everything up by reduxing a big AN970-4 washer onto the outer faces of the W21 plates, the AN4-21 goes through that as well as the FL9s, so that the poor FL9s dont take all that wear?

Does anyone have any ideas on that, or any other way to impart extra strength around the pivot holes in the W21 plates?

Hi Richard,

please read the message below.
Maybe that is an answer to you.
I will try it during next delay.
I have about 250 landings so far and you are right - then there is too much sideplay.

Hi Jim

The Mod is on the Europa Club website. It is Mod 10661 Version 2, May 2007. Version 2 changes the pivot bolt to AN5.

We've done this Mod and it works fine.
