How to obtain reaction forces in Mechanism Dynamics Option (MDO).

[Rubio74]

First of all, this is my first MDO project. It is all relatively new for me.

I want to get axial reaction forces in a frame of a cylinder housing in order to simulate vibrations.

I used 4 pin constraints and created measures on them. They work fine in radial directions, but not in axial direction. Only 1 constraint reacts, no matter what loads I apply.

I tried both with a constant force on the piston as a torque motor on the drive-shaft. Most of you Creo guru's will recognize the model.. Which mechanism constrain do I need to get all the reaction forces? The shaft makes 1 revolution in 0.06 sec. Model attached (engine.asm)
