856 and 706 shift parts interchange

I found a junk 856 I believe it is. Guy said I could rob parts on the
cheap for my 706. I got the rear fenders and the cowl that goes over
the shift linkage and stuff right in front of the steering wheel.
Someone ghettofied some of my shift linkage on the
Reverse/foreward shifter and it kinda looks like those parts match. Is
that right?
 
A 706 is 2 inches shorter. All the shift rods will need to be shortened accordingly.Yes,you can adapt a 'shift kit' from an 8 series and biggr to a '7',but everything needs to be cut down. The range transmission top cover is interchangeable so no issue there.I have converted a number of 06 series tractors to 56 series shifting. It really isn't hard,just takes a bit of time.
 
On your 706, do you need to move the shift lever right and down to get to reverse from neutral? If so it has already been converted to 56 style shifting, and the parts will bolt right on except for shortening the rods as mentioned before.

A 706 from the factory will have the ranges all in a straight line, and these can get troublesome as they wear. They all can get troublesome as they wear but the original 06 shifting just does it sooner.
 
Mine is straight line shifting. I cant get reverse until the tractor is good and warmed up.

There was a huge rats nest under the cowl and I had limited tools. (I was there to get the fenders off this tractor) anyways the tractor is very scrapped out but the range shifter is all there. Someone has already robbed the 1-2-3-4 handle.

On another note, where might a guy get the springs that stabilize the TA handle? Mine wants to stay in low and you have to hold it in 1:1. Looks like it is missing a spring.
 
You will probably need to go to IH for the spring. Or find a junk tractor.If you swap shifters,the reverse shift fork is different for both 06 and 56.The shaft that carries the fork needs to be cha.nged as well. It will come out from the rear. Remove the top link plate/cover for access.
 
Cant get to reverse till warm sounds like a TA adjustment issue. Couple that with a bunch of worn parts and you have a problem.99% of the time it is in the cover. The pivot shaft and bushing gets worn,a roller can fall out of the shift cam,the shift cam itself gets a worn/flat spot,the reverse shift fork get a groove,or all.....Dont forget to look at the pins and clevises in the linkages as well.The damage is cumulative,a 1/16 inch of wear on top at the lever can become a half inch down on the underside of the cover.The 'Tractor Vet' has posted an excelent TA adjustment procedure.It can be found in the archives.Or,get yourself an IT repair manual.It will have the factory adjustment procedure in it.However,the Tractor Vet's is better.
