I just put a seal in a 1750 and there is a lip seal with a felt on the outside of it and shims to adjust the bearings. The wheel has to come off.
I wonder if you took some shims out. If you cut them cleanly you can take them out without removing the wheel and still reuse them later.
If you need bearings the PTO has to come off to get the axle out and when you change the shims that moves the seal which can cause some problems.
Pay attention to how far the seal is pushed into the seal holder. The axle was rough where the felt ran on the one I worked on.
