What happened was pump was misaligned and ate up the splines. The spline part is all that is wrong. Through a farm show article, I found where someone used the high gpm Prince pto pump to replace the one on a new Holland 1475 swing tongue swather.
I guess I'm trying to confirm this more. My pump is on a hesston 1014 swing tongue swather. The gpm's are right and he just adjusted the pressure some. I just am looking for more opinions, and I am gonna go into town and check at hydraulic shop, but it's a long drive to do that also.
