Over rotated wheel fork? Bad side-to-side shimmy?

Looks like what might happen if the nosewheel smacks over to the side when rolling backward. Are the holes in the collar worn/elongated? How about the hole in the gear leg.

It's hard to tell from the photo, but it doesn't look like there's any polishing or wear where the stop hits the collar, like you'd expect with chronic nosewheel shimmy.

Yep. Sure is. Good catch.

Right on Scott. The stops should face forward. Who done that?

Thanks a lot guys..... I'll take a closser look.
No shimmy, but the last time I landed, after buttoning her up from my annual, there was significant headwind and gusting... 35kts + 15-20. Touched down, held the stick to my belly as usual, but when the nose wheel touched down (at low groundspeed) there was a noticeable jerk of the nose wheel.

Order a new part from Van's and put it on in the correct direction. This would be a good time to clean everything and readadjust the torque on the Bellville springs. I'll try to post a picture of the work I just did on my plane sometime this week.

Default Lots of times

I have seen that numerous times on legs people return for updating for the service bulletin or to get replaced for whatever reason.

I have also seen lots and lots of people install them backward like what you have.


For a while I was even confused as to what was correct since there were so many installed backward.


Could be related since it would really reduce the amount of travel available for the nose wheel swivel.

so... in this position, someone pushing the plane backwards without a tow-bar and the castoring (castrating) wheel could've hit its limit earlier and caused this deflection.... i'm thinking...

i'm probably guilty when converting to the more recent designed fork and having the nose gear leg modified for the newer fork.

(but i swear that's the way it was when i took it off)
