How to remove the hydraulic lift pump on a 1970 Massey F. 135

[Peterpiper]

I have removed the side pins and the front of the Multi-Power pump.
The nuts(pump adjusting nuts) seem to line up with the holes in the wheel, but it just won't go back far enough to get it out.
Anyone remember how to do this?
Thanks!
Gary

The tractor has to be split. Not too difficult, just time consuming.
