O-ring kit for 4020 steering motor ?

Has anyone ever rebuilt a steering motor, the one that the front end bolts to, on a 4000, 4010 or 4020? I'm going to replace mine and would like to put a kit in it. Thanks again.

Yes Deere offers a o-ring kit,but you also need to order the lower seal,it is not included(I'll post the part #'s after bit)block the tractor up good at the cluctch houseing/oil pan area, remove the front end and steer arm remove the right side frame,seperate the oil lines up front,both off them,remove the two caps locking the piston plugs in,hammer the caps in a bit to release the presure on the snap rings (oil will spray out of the open lines,cover them with a cloth),remove the round snap rings, if you can't get them up out rig a way to push the plugs in a bit more, you can use a pointed punch and hit the ring about an inch from the end and this will let it curl up a bit to get a hold of it, after they are out fit a slide hammer into the 3/8 threaded holes in the pluge and pull them (a pint of oil will come out)center and measure the distance from the end of a piston to a point at the end of the bore(this will help you center up later),remove the 6 1/2 cap screws under neath and drop the pinion down out (don't pry on the oil lines) it will be tight up in there, remove the big snap ring on the pinion to get to the lower seal pull the pistons and re seal, then center them back up put the pinion back up in(there is a front and rear to the pinion,mark it before you remove it,two holes are closer on it) before you re-install the end caps turn the pinion left and right to make sure the timeing marks line up,,Wow, that was more typeing than I was ready for this morning, mail me if you want, I do one or two a week around here, just did a 4040 yesterday..

The steer motor kit is AR 52016-$59,,R 34748 seal-$28

Thanks Tim for your help, what I have is a 4000 I'm going to replace the steering motor on because the housing is cracked, just wondering is the motor the same for the 4010, 4000, 4020 or any others? And thanks again.

Yes, same as a 3020,4320 also,,If you get a used one I would re-seal it "before" you install it, Anderon Tractor at Bluffton Ohio has them 419-358-8846
