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.
