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.

I have one of Neil's 3.17 psru with Tracey's cushion drive. *I also sent Neil an email but it's late in the night in Australia.

After my fly off hours, tearing down the plane to inspect everything. The Ultra-Low-Friction Oil-Embedded Thrust Bearing is broken into pieces.=C2=A0

The=C2=A0nylon 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?
