The design of Van?s electric flap actuator system leaves much to be desired (IMO). As the flap actuator rod goes up and down, it twists left and right causing the flap actuator detent rod to bind in its narrow switching track.
Vans issued SERVICE BULLETIN 7-4-12 designed to stop the jackscrew from disconnecting from the flap actuator rod, but this does little or nothing to stop the flap actuator detent rod from binding in its narrow track.
We believe we came up with a solution to stop the twisting motion. Using a steel washer we machined to have a concave shaped hole, the inner, tapered circumference of the washer bears against the convex bearing limiting its rotation (left and right) without limiting its rotation around the flap actuator weldment shaft.
In other words, the bearing operates normally but does not swing around causing the flap actuator detent rod to bind in its narrow track.
[font="]We welcome comment on this suggestion. I suspect some folks have not had a problem as designed (yet) and others simply tolerate the matter altogether.
