+1 on the request for drawing and part numbers!

Thanks!

Had to laugh when I saw this post. I think we even used the same utility cart. Here's my take on solving the same problem, built 15 or 20 years ago.

FYI. REF: Steve G. commit about the home made mule, I used his a few times to do the gear swings. The only problem, which I'd like to know about the other members mule, is at the high pressure at the end of the gear cycle the electric motor would bog down and trip the circuit breaker. Steve uses, I think, half horse. Did the other member use a bigger electric motor??
BILLS

I used a 2HP, 120V motor. It's more than sufficient to operate the gear thru its cycle but has trouble building sufficient pressure to return the gear handle to the neutral position. I suppose a 5HP, 240V motor such as might be found on an air compressor would be a better choice. More grunt, less current draw but significantly higher cost. Or design a geared drive rather than direct drive, but again at higher cost and complexity. I can't help with the weak 15amp circuit breaker.

For those that requested, I will put together a readable drawing with parts list soon.

Some years back
an A&P removed hydraulic pump from the engine, leaving hoses connected.

Then used hand held battery drill to spin it.
Worked like a charm
