Composer Actors Relocating when applying Kinematic Relationships

Hi Composer Users

I am attempting to set up my model of a hydraulic ram with Kinematic Child Parent Relationships.

As soon as I create the link of Child to Parent, the Child Actor is relocating in 3D Space.

Sometimes it seems a random location and other times what would seem to be it's Neutral Position.

Has anyone else encountered this and know how to get the Child Actor to behave?

I know they say "Never work with children or animals" but I have no choice

thanks in advance

Tony
