Looked on JDparts, cant see where the trans pump shaft is driven off of. Is their a bushing on both ends? Pulled the cover off the top of the trans, everything looks good..Started it, let it get warm,o strange noises from that area. I am starting to think its somewhere in the clutch housing. Tractor also seems to have more vibration that normal.Engine was overhauled this summer with a new crank pulley. I did an inframe, so I didnt look at the clutch.Is it possible to have a vibration at that end.. Either way between the rattle and the vibration something is wrong..Have to start somewhere. Any help would be appreciated. Thanks!

You will get a lot of strange noise with the cover off,so don"t let that lead you astray, the trans pump drives off a plug seated in the back of the crank shaft, rarely is there any trouble on that end.
 
The only reason I ask is,the shaft pulled out very easy, went in easy. I decided to pull it back out some to spin the pump by hand to feel for any play. Anyways, I could not get the shaft back through the pump,it got hung up,is their a bushing on the other end? Regardless I am going to have to split it to figure out where this noise is coming from..I know its not in the trans,so maybe I should start with a split at the clutch? Thanks for all your help, if you were closer I would pay you to do it. Thanks!

There is a bushing at the rear of the hi/low pack, but if you rotate the shaft it will line up. i have a 4440 Quad that I just brought in with a bad noise as it pulls going forward, on the coast it goes away,,I'm thinking the bottom shaft rear bearing, I'm going in from the back on it, pulling the cab, final drives then setting the transmission off .,On the 4440 power shift I have in here it was slipping in all the gears, the pressures were near right so I went in from the front, the dry clutch is bad...I'm gonna pull the C1&2 clutch packs out and inspect them and the trans. pump while I'm in there...
 
Upon a second look at the trams pump shaft it is bent not sure how that could happen. Figuring that might be my noise. Ordered new shaft and pump today start there with the easy stuff. Next it will get split. Thanks
