That looks and feels so wrong on a Rotax. And no chocks......

Pete,
Could you explain further what is the problem? From the photo I don't see anything
wrong.
Thanks,
Jim

Hi Jim,
The swingarm is not centered and does not clear the frame (pilot side) to drop
the gear. The locating tabs on the swingarm tube are incorrect and nit crnteted,
although are the exact correct width (no lateral play) wrt to the swingarm
bushings.

H Pete,
I am afraid your description and photo do not tell me a great deal about your problem
BUT I would like you to check something that causes a restriction much
as you describe Ie leg not retracting or extending properly. I would use a manual
page to refer you to but I am unable to get onto the Europa Aircraft web site.
I know I am registered but they don't think I am.
There is one unit that can be fitted either one of two ways round. One is right
and the other will give you a problemm such as you describe. I now have a tri
gear so only have immediate access to a Tri Gear manual. Not too helpful when
you are talking Mono problems.

Subject: Europa-List: Frame/gear offset error?
Hi Folks,
My kits (circa-2001) frame seem to have an offset error on the swing-arm tube
centering tabs, making it not possible to drop the gear without interference.
Anyone else seen this error? Looks like a fiddly fix to carefully grind down
one tab and adding to the other.
Picture is attached (if it gets through - also posted on the Europa Aircraft Owners
FB page)
Thoughts/experiences anyone?
Many thanks,
Pete

Pete,
What do you mean by centering tabs? From you picture it looks like the swing arm
needs to be moved over slightly to the S.B. side. I believe the lateral position
of the swing arm is set by the LG08 legs which are centered in the large
diameter cross tube and LG02A which is bolted to the swing arm. Looking at
your picture it doesnt look like the LG08s have been mounted to the frame yet.
I suspect you just need to clean up the bearing surface on the lower frame to
allow the swing arm to slide closer to the port side down tube. Or perhaps
I am missing something and got it all wrong.
Regards,
Erich

Indeed the swingarm is centered on the lower frame tube by two small tabs we
lded onto the top of that tube, which ride on the inside vertical surface of
the arm=99s brass bushing blocks. Those tabs are nicely tight on the
swingarm to prevent any lateral sliding of the swingarm on the tube, but sa
dly they are offset to the pilot=99s side on mine, preventing the swin
garm from clearing the vertical tube. I was just wonder if others had seen t
his fabrication error, or if mine was a one-off mistake.
Cheers and thanks,
Pete

Peter,
Photos can be deceiving but in the photo attached, it appears the brass
bushings may be offset with respect to the swinging arm. As a point of
interest, have you tried inverting each pair of bushings to see if there
is any improvement?
If the tabs as you call them are different distances from the side frame
(a fabrication error as you suspect), I think I would be tempted to
simply grind away that part of the swinging arm that conflicts. There
is not much clearance at the best of times in that area.
Now to answer your question . . . . . No I haven't seen that fabrication
error but I have seen a different one on the same framework.
Cheers
Kingsley
