Rotary Cutter Bush Hog SQ72 gear slack

[mwayne]

I'm replacing the PTO shaft seal on this 30 year old machine and while it looks like the input bearing is smooth and tight the shaft has just under an eighth of an inch of axial travel. Does anyone know what the spec is for this? Also I see this is an obsolete gearbox as far as Bush Hog is concerned, if I needed a replacement is one available elsewhere?
Thanks!

Just because the box is obsolete doesn’t mean the parts for it are. You probably can buy bearings and shims and rebuild it.
