Makes sense...weird it's a technique in an FAA approved repair document.

Belleville Washer
 

Any idea where I can purchase a Belleville washer for my RV6A. I've tried to find one on VAN's site but have had no luck.

The part number and name: U-611 Disk Spring. You ca go to Van's site and search the store with the above part number. Price is $3.30 each

Thanks for the info. Typically, do you only use one? Tom

You need two Belleville washers. They go on with the ?cups? facing each other.

Bevan, I really appreciate you responding. Big help !! I did not build my RV6A and have had some shimmy ever since purchasing it 3 years ago. I've tried other things mentioned in the forum but not this; want to be prepared when I pull it apart. Thanks again. Tom

Thought I'd share with you what I found... I ordered 2 new B-washers from VANS just to have them available if needed. When I removed the nose wheel assembly, I found 2 washers already installed BUT they were both facing the same direction. Installed the 2 new ones as intended and my first (and only to date) was successful; no shimmy! Wonderful!
