Default L2650 steering play

Our L2650 4WD had 4 inches of play in the steering. Tierods and linkage is good. I tried to take it out by adjusting the sterring box sector, but it was tight. Pulled the box and only found that the Ball nut assy shaft had play. I twisted on the shaft and it would move in 1/2 inch. when I let go it would spring back. People (who have tractors) tell me that a lot of play is normal for tractors. The book says only 1 inch is allowed.

Is your L2650 a PS equipped model? I had the same issue in my L2650DT with factory Power Steering.

Issue was located in the PS pump. It is piggy backed behind the hydraulic pump and the coupling shaft is known to fail. When it does, the PS control valve in the steering box, cannot "centre" without it's required PS pressure, so the steering is "wobbly", has excessive steering wheel movement before the tracto turns, as well as generally "hard" steering effort.

If you are convinced that the steering ballnut is OK, and you have a PS equipped L2650, pull that PS pump and look for it's input shaft to be sheared with the possibility that the gears inside the pump are frozen.

The tractor does have power steering, but it is not hard to steer. The only real problem steering is after a turn or if you are mowing on a hillside. Then is wonders a bit. The tractor has a bucket on the front and it has been over loaded plenty of times. Plus someone else that uses it leave it in 4WD all the time, even on the pavement. The slack in the steering is there when the tractor is on or off.

If that's the case, then it may be a worn sector in the steering box. Any chance it's leaking up there?

Sector is tight and I have no leaks. I took the sector out to be sure the problem was not there. I found no wear at all. I can twist the ball nut shaft and it is spring loaded. Only springs are in the power steering unit. Maybe the housing is worn, but that doesn't seem likely.
