•Replace hex nut and lock washer and retighten the jam nut after proper adjustment is achieved.

NOTE: Threading the ball joints too far onto the drag links will cause the front tires to "toe-in" too far. Proper toe-in is between 1/16" and 5/16".

Front tire toe-in can be measured as follows:

•Place the steering wheel in position for straight ahead travel. Insert a 1/4" dowel up through aligning holes in both the steering gear and support plate. See Figure 11.

Adjust the drag links so that equal lengths are threaded into the ball joint on the left side and the ball joint on the right side:

•Loosen the jam nut found on the drag link at the rear of the ball joint. See Figure 10.

•Remove the hex nut and lock washer on the top of ball joint. See Figure 10.

•Thread the ball joint toward the jam nut to shorten the drag link. Thread the ball joint away from the jam nut to lengthen the drag link.

•In front of the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.

•Behind the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.

•The measurement taken in front of the axle should be between 1/16" and 5/16" less than the measurement taken behind the axle.

•Adjust if necessary.

•Remove the dowel inserted earlier before attempting to operate the tractor.
