My annual is due next month and I plan to implement the changes. Dennis H is working on a sleeve bushing to repair the wear area of the input shaft. Starting with an undamaged input shaft, it’s likely the single 5mm bearing with the bronze cage will eliminate any future wear in this area.

Looks like an optimum, easy to implement solution Steve, I like it.

The work on the oil level problem was brilliant too, I’m going to implement your solution on mine.

Tracy,

 

I've installed a 5 mm thick IKO AZK35535 bearing replacing the 2mm thrust bearing stack along with spring loaded pins to preload the bearing and stop the plate side thrust washer rotation during torque reversal.  The photo shows one of the pins as well as the cupped middle thrust washer stack that was abandoned.

 

This seems OK on the test stand but has yet to fly.

 

-5 degrees F this morning, but the frost makes a nice picture.  I don't know why some photos end up rotated.

     Steve,

        Are you using the all bronze cage bearing or the bronze cage with the steel outer band ??...........
