Assembly notes:

• Replace any locking fasteners that show signs of wear or reduced locking function. In some cases, the parts may be thoroughly cleaned and locked with re leasable thread locking compound such as Loctite 242 (blue).

• Replace the hex bushing that locates the steering shaft, the spacer at the center of the steering gear, and the bushing on the end of the drag link to tighten-up sloppy steering, in addition to confirming that the gears, wheel bearings, and axle bushings are in good condition.

• Apply grease such as MTD P/N 737-0300A (Benelene), or anti-seize compound, to the friction surfaces and teeth of the steering gear on assembly.

• Make a visual inspection of the steering gear and pinion gear, paying particular attention to the condition of the teeth. If either are worn or damaged, replace both gears and any suspect bushings and hardware.

• Apply anti-seize compound to the bearing surface at the base of the steering shaft.

• The screw that secures the bottom of the steering shaft should be thoroughly cleaned and locked with re leasable thread locking compound such as Loctite 242 (blue). Tighten it to a torque of 17-20 ft.-lbs (23-27 Nm).

• The screw that secures steering wheel to the steering shaft should be thoroughly cleaned. Re leasable thread locking compound such as Loctite 242 (blue) should be applied to the threads. Tighten it to a torque of 17-20 ft.-lbs (23-27 Nm).

• Tighten the steering gear shoulder bolt (passes through the curved slot in the steering gear) before tightening the steering gear pivot bolt (passes through the spacer at the center of the steering gear).

• The steering gear shoulder bolt should be tightened to a torque of 200-260 in-lb. (22.6-29.4 Nm).

• The steering gear pivot bolt should be tightened to a torque of 200-260 in-lb. (22.6-29.4 Nm).

• The ball joint nuts should be tightened to a torque of 150-250 in-lb. (17-28 Nm) after removal or adjustment.

7.1. Thoroughly test the steering before returning the tractor to service:

• Test for ease and freedom of movement.

• Check for loose operation or hardware.

• Turn to full-lock in both directions to check linkage travel and steering gear.
