So I worked on it today, I needed to get the inner shaft off the birfild. I have been able to do this before with a short lenght of PVC tubing and piece Plywood on the floor.
Repeated slams Tue. evening netted zero results.
Came back this morning same thing nothing. So I called my friend Randy
@raisinhell2 and asked him how he does it, he said the same way except he uses a steel pipe and slams it onto a piece of steel plate.
I was reluctant ( afraid of damaging things ) he assured me not to worry, so I grabbed some 13/4" steel tubing and some 1/2" plate steel and went at it, I kept raising it higher and slamming harder tell on the forth try it popped lose. Zero damage

including the inner snap ring which I had to reuse because they did not sent one with the birfild.
When I spoke to RCV yesterday they confirmed that they wanted the defective birfild back and that I should have received shipping label and snap ring. when I asked if I could purchase a spare snap ring they offered to send out 4 of them at no charge with the shipping label.
They won't arrive tell next week so, I was happy the one inside of the birfild did not get damaged.
