I just replaced the Maule tail wheel with a Scott 3200 Alaska Bush wheel and I am experiencing a lot of shimmy. The wheel was a little used so I got the rebuild kit from Alaska Bushweel. Should the springs to the hornes
be change from the Maule compression type to the Scott style as there is still some shimmying going on? Also it appears that possibly there needs to be a slight shim between the leaf springs and the plane to maybe position the the wheel a little further forward and under the tail. Any advice would be appreciated. Thanks, Jim

The steering springs and chains should have a little slack, otherwise the wheel can set up oscillation between the springs.
Either steering springs will work on the ABI steering horn if you have the one with upturned ends.
If no upturned ends, the steering horns are shorter and the chain angle is steeper and the horns can get bent with the Maule steering springs which should have the stronger one on the right side.

Here is a good video on rigging the Scott tailwheel also check that spring as mentioned also it may help to keep the pressure on t e low side for pavement operations. I had problems with mine at first new springs and rebuild helped and running a little less pressure on pavement.

what pressure are you running in the baby bushwheel...i have a slight shimmy too on a brand new spring... angle is correct...can't view the video it says it doesn't exist....oh just saw you have the 3200... well if anyone knows pressure in the baby bush wheel and whether that could be the problem let me know....

Overgreasing, or wrong grease which can migrate from the swivel bearing area into the anti shimmy clutch area can also be a problem as there will be no friction on the friction plates. In that case clean it out and rebuild.
Sometimes the friction pressure springs are tired and in the babybushwheel case 5 springs rather than three is optimal.

Tailwheel shimmy
Tried everything but could not stop the shimmy in the Alaska tail wheel shimmy. Finally put the standard 3200 on and problem solved! Thanks to all those who gave suggestions. Jim
