When installing the hardware to attach the throttle cable to the throttle arm, the instructions ask for the Rotax locknut (silver in color, blue locking insert) to be re-used. This nut should hold the VA-219 bolt which has a hole for the throttle cable to pass through.
When I was trying to tighten this assembly, I noticed that the nut went on the bolt without hesitation - even when the locking feature was passed. Also, it appeared to be odd that the Rotax lock nut is a metric size while the head of the VA-219 needed an imperial size wrench.
My lock nut tightened a bit until it sheared off some threading and then would not go anywhere except off.
Closer examination showed that the VA-219 threading is indeed imperial size and the lock nut was definitely not.
I decided that an AN365-1032 locknut should be a perfect fit, given the dimensions of the VA-219.
I searched the forum but could not find anybody else having this problem. Am I missing something? My 50-05 is revision 1 from 10/12/09 and has not been revised since.
