Kenny: There a lot of threads dealing with that problem in the archives. Just type in "steering" and you'll find plenty of threads. It's pretty common on the old row crops. You have basically three adjustments you can make. Steering shaft fore and aft, pedestal shaft vertical end play, and eccentric tilt for sector to worm mesh. The vertical adjustment involves jacking up the front of the tractor, putting a dial indicator on top of the shaft, and using another jack or a lever, lift the shaft up and down to see if it's excessive. Most folks skip this adjustment if they don't have too much front wheel flutter. So, check the fore and aft shaft play next. Move the sector eccentric away from the worm so you can feel and/or measure the endplay. Add or (probably) remove shims to make the clearance so that the shaft turns without a ton of effort but it doesn't move in and out as you turn it. Now you can set the sector to worm mesh using the eccentric adjustment. Here I like to have the front end jacked up so I can really feel for any interferrence. Make the adjustment at either near extreme left or right. This areas have not seen much wear, and if you adjust in the sloppy center, she will be sure to bind on the end of travel turns. By now you will have removed all the play you can without replacing parts. If it's still sloppy, you might have a bad bearing(s), or a sector/worm worn too bad to adjust, which might require a deeper repair. Frank-in-Tallahassee
