Loader pump drive connector

My 1963 65 diesel has a MF99 loader mounted on it. There is a plate with three countersunk capscrews secured to the front pulley and that plate has a long 3/4" shaft brazed to it. That shaft is machined for a woodruff key and it enters but does not completely pass through an 1.62" hole on the front axle. As the tractor is idling the end of the shaft inside that 1.62" hole has quite an orbit to it, maybe .25". I'm trying to find a pump coupler that would accomodate the shaft runout but everything I've found has a massive OD that won't fit inside that 1.62" hole. What do your tractors have for a coupler? Any suggestions on how to solve is? I don't know what the original Massey set up would have been. Haying season is getting closer so I need to get this figured out .

Thanks. Tim
 
Usually the front pump drive that bolts to the front pulley has rubber bushings to compensate for any misalignment. The drive shaft usually screws into the drive plate bolted to the front pulley. The online AGCO parts books are down for some reason right now so I cant look up any part numbers at the moment.
 
Thanks pt. S/N is SNDW686014. The illustrations in the AGCO online parts book aren't clear to me. Does anyone have photos of the real
items?
 
The part numbers I listed will work
1401814M91 Shaft Coupler (should look like this, the shaft, and coupler are welded together)

704812M92 Adaptor Assembly (should look like this)

Thanks once again. The pix are helpful and I'll take a closer look at mine and see if there are rubber bushings in the mount plate. Last
question, with this set-up then, the pump is coupled to the shaft with a solid keyed sleeve? Just slide the two together and tighten the set
screws?
