Place a ball of putty (4) on the left engine end frame (6) . The diameter of ball should be approximately 19 mm (0.75 inches). The ball of putty will be squeezed between the non-engine end frame (5) and the engine end frame (6) .

Move the transmission direction and speed control lever to the NEUTRAL position. Start the engine. Raise an empty bucket to a height of approximately 300 mm (11.8 inches).

Run the engine at high idle. Turn the machine all the way to the left. The machines with command control steering turn to the full left command within one second.

Steer the machine so that the machine is facing straight ahead. Engage the parking brake. Lower the bucket to the ground. Stop the engine.

Measure the thickness of the ball of putty (4) .
1. If the frames did not contact each other and the thickness of the putty is less than or equal to 15.7 mm (0.62 inch) then adjustment is not necessary. Repeat the procedure for the right steering neutralizer. Repeat the process starting with Step 5.
1. If the frames contact each other or the thickness of the putty is greater than 15.7 mm (0.62 inch) then an adjustment is necessary. Proceed to Step 11.

Adjust the striker (3) , as needed. Adjust the striker in order to obtain a 12.7 ± 3 mm (0.5 ± 0.12) thickness of putty. Lock the striker (3) in place with the locknut (2) .

Place a ball of putty (4) on the left engine end frame (6) . The diameter of ball should be approximately 19 mm (0.75 inches). The ball of putty will be squeezed between the non-engine end frame (5) and the engine end frame (6) .

Move the transmission direction and speed control lever to the NEUTRAL position. Start the engine. Raise an empty bucket to a height of approximately 300 mm (11.8 inches).

Run the engine at high idle. Turn the machine all the way to the left. The machines with command control steering turn to the full left command within one second.

Steer the machine so that the machine is facing straight ahead. Engage the parking brake. Lower the bucket to the ground. Stop the engine.

Measure the thickness of the ball of putty (4) . If necessary, repeat Steps 11 through Step 16 until pressed thickness of putty is 12.7 ± 3 mm (0.5 ± 0.12 inch).
