OK, the saga continues. I installed a new tailwheel leaf spring and we also installed a shim to ensure a positive castor angle. I have the light compression spring on the left and the heavy one on the right per the manufacturer. We also set up the springs with 1/4 inch compression per Maule instructions.
When the tailwheel was off the plane, there appears to be no slop in the oiloite bushing.
When the shimmy begins, unloading with a small amount of forward stick will make it stop.
We can do the following:
1) install a new oilite bushing and/or change to a solid tire from the pneumatic (if allowed by the TC) with will further increase the postive castor. (maybe a solid tire is not a good idea either - don't know).
2) punt and change the entire assembly (more expensive than I'd like).
This tailwheel was fine for 120 hours of operation.
