The splined hub that drives the hydro pump is starting to get a fair amount of play in it. I am down now with rain and was thinking of installing a different hub. Can this be done without removing the pump completely from the machine? I realize the shaft may have some wear also but was hoping to make that a winter project. Was hoping I might be able to move the pump away from the housing enough to work in a new hub without removing any lines. Anyone ever do this. This is on a 1470 which is same as a 1460 in this area.

I know on the 1680s and 23s I have changed those belts but man it's been a long time. That pulley should come out

An update. Yes it can be done. Previous owner had cut an access hole in the side of the body panel that covers the hydro pump. Without that I don't think you could do this the way I did it unless you removed the complete panel. I just looped a chain over the unloading auger tube and took a cable come along to lift with. Was able to push pump out of the way enough with all the lines still connected to remove the pulley through the belt opening. I suppose I was about 3 hours doing this so not real bad. The splines are wore on the pump shaft and a lot of the play is deeper inside the PTO once I got things where I could see what is going on. Guessing the flex plate may be where the main issue is. I hope this will get me through the rest of the season if the rain stops.
