7112 clunking in bgb

[joshuaareed 0]

A good friend of mine got a 7112 today. The tractor starts fine, runs fine but will not move.It is a hydro, but there is a clunking noise coming from the bgb. The pullies won't move but are not siezed up. Any ideas?

Could be a keyway sheared or worn in the input shaft from the drive shaft but it sounds like a busted set of gears in the gear box.
