Matt,
Were you using the snubber and the Oil embedded thrust bearing in the stack?

I was under the impression the snubber thickness set the end play. The one supplied by Tracy is not flat and I had assumed it was not an off the shelf item.

Too little or too much end play?
Tracy specifies 0.005 to 0.035"
Note that if you check it without RTV, it may increase when you assemble it.

After my fly off hours, tearing down the plane to inspect everything. The Ultra-Low-Friction Oil-Embedded Thrust Bearing is broken into pieces.

The nylon or teflon washer supplied just melted. I thought I nailed it with a fix using the oil-embedded, but I guess not.
I think in Tracey's documentation, he called it a snubber ? Any ideas what I can use, or why this happens?
