Mechanisms: Difficult pump assembly

Mechanisms: Difficult pump assembly

Mechanisms: Difficult pump assembly

(OP)
I'm having problems getting mechanism to allow motion for an assembly, see link for pic.
http://www.fti-cvt.com/diagram1.jpg
The cylinder block spins around its own center axis, and the bearing spins around its own center axis, the piston spins with the cylinder block but stays mated with the bearing face, so that it comes in and out of the cylinder bore. I've tried every combination of connections I can think of, and can't get motion after they are assembled. Any suggestions on how to make this work?

Any general suggestions for getting difficult connections to work?

RE: Mechanisms: Difficult pump assembly

Which connections are you using...for..?

a) The piston in the piston block?
b) The piston on the bearing/slipper plate?
c) The piston block and the bearing?

Regards

Adrian
