both output of hydraul shift and input shaft of trans. have the splines worn hard , coupler sprockets slop back n forth , does anyone have a fix for this or know where to get these shafts new , how hard is it going to be to replace them , also any recommendation on where to get the new chain and sprockets for coupling them shafts , some say after markets dont hold up to get them from agco , engine is out for overhaul and will be turned up a bit , dont want things flying apart once it is back to work in spring , it does get used for heavy tillage with dual wheels , this one works hard for a living and has treated me very well , .......more then i can say for my 4430 deere with its million dollar jerk-o-matic trans, but thats another story
