Forget the weight until you figure it out. You need a careful examination of the carriage to determine what's up. I can't tell well enough from the photos to diagnose anything.
KHB Photographix is the Canadian supplier for parts, and the D2 manual is available for $10:

My recommendation would be to remove the Aristo and look carefully at the carriage mechanism, or email KBH.
Yep, I think there’s some major malfunction somewhere. I’ll contact KHB. Thanks, Philip.
Re: D2 cogged wheels not fully engaging rear column
does the D2 have a locking knob on the bottom that needs to be loosened before raising the head ? on the D5 it's on the bottom of the carriage, facing user, below the elevation crank.

Fred, yes, it does. It’s loosened, but the head is still frozen in place.
Re: D2 cogged wheels not fully engaging rear column
There are 4 rollers riding between the column and the carriage, they look like small train wheels. Check those for alignment.

I think I see what you’re talking about. On one pair of rollers, one turns freely against the column, while the other is stuck and won’t turn. Same for the others.
Re: D2 cogged wheels not fully engaging rear column
Sounds misaligned, it should be fairly easy to put them back on track.
Re: D2 cogged wheels not fully engaging rear column
Best way to work on it would be to set it on a table allowing access from all sides.
Re: D2 cogged wheels not fully engaging rear column
I had to double check mine to confirm, the shafts that the guide wheels are on
are off center drilled, so the become an eccentric shaft.
You can loosen the screws on either end of the shaft and rotate the shaft
so the wheels make contact with the rails, there is a hole drilled thru the shaft
just for that purpose ( stick an allen key in it to act as a handle to rotate ).
Just make sure the lamp housing and condenser are removed.

Thanks, Jim. I appreciate it. I’ll give it a go.
