Gear Relation; Animating Assembly Error - Unable to apply transform. Instance(s) may be constrained.

I've got a motor with an output mated (using gear relation) to a spur gear on a mount. I'd like to animate the motor output so that it spins the spur gear, which I can do but the result isn't quite what I need nor expect. If I animate the revolute mate of the motor output, the output shaft stays still, the motor spins around the shaft and the spur gear remains still but the mount rotates about the spur gear. If I fix the motor in place, the motor output spins which then spins the spur gear and mount as one whole item - almost! If I fix the mount, the animation fails 
I've tried switching the order of mate connectors in the revolute mate. The gear relation order can't be changed. I'm struggling with this - can't believe there are so many options that change the outcome to every result other than the one I need.
Can anyone help me narrow down or find the issue? Here's a link to the assembly:

The 2 spur gears have a fastened mate between. If you suppress this mate and 'Fix' the yoke and the Motor Mount Plate the animation will work.
(To 'FIx' a part right click on part to get context menu. Fix only works locally so if a part is fixed in a sub-assembly it won't have any effect in the main assembly)
