Worn 656 Shifter

I have a 656 loader tractor that the shifter is getting worn . If you don't shift it slow it will hang in 2 gears . What do I need to look for ? Is there something I can build up ? Thanks for the info .
 
Right now the CNHI parts page is down for updates. Need
to know if you have a Farmall row crop or utility model. Do
not know how familiar you are with it but a linkage with two
rods and a bell crank transfer the shifter motion from the
shifter down to the transmission. One for each set of gears
on either side of neutral, as in reverse and first. So there is
3 sets. Tightening up the slack in all those joints is what
needs done, new pins for all the joints is a start. I will link
another parts site that shows the diagram for the Farmall
version. Do a web search on this problem a lot of info will
come up.

Ah no thqat is not how the shifter works on a 656-686 Ya have THREE RODS running from three levers on a shaft that slide thru the levers with a pin that makes contact with the slot on each lever / arm what ever ya want to call it . What happen is they ware the pin can snap off on one side but not the other and they still will shift but they have more slop now . The ware is mainly between the levers/ arms . I have had some luck with shimming them closer together on the outside of the Rev /1 shifter and the 4/5 shifter and replacing the pin in the slide shaft . You may find ware where the rods connect to the shifter lever arms at the slide rail and also down under the battery box . They are noway near the shifter used on the 06-86 tractors .
