I am working on a 1947 Farmall A. The tractor was abused by the previous owner by pulling a 5' bush hog. The 44 tooth pto gear keyway and the pto shaft were wiped out. I installed another used pto unit. When this pto is engaged to run a 5' Woods belly mower, there is a rough growling noise coming from the transmission area. The rear spline shaft caged ball bearings seems to have excessive play. I think I need to remove the spline shaft and replace the bearings and front seal. I know the transmission front needs to be split from the torque tube, but how is the spline shaft removed? Is there anything else I should be looking at that may cause this noise? The noise is present even when the pto is engaged and the tranny is in neutral. Thanks for any replies!

I've rebuilt two of these in the last year, and as I recall, the top transmission shaft comes out the front of the unit. the lower shaft, of course, goes out the rear because the pinion gear is on it.
