ACTION REQUIRED

***** Parts Stock *****

Remove all 117-2247 Draft Balls from dealer parts stock.

***** Affected Product *****

Refer to the Service Manual, Operation and Maintenance Manual, and Parts Book as necessary.

Replace the existing 117-2247 Draft Ball with a new 243-6690 Draft Ball.

Measure the end play that is between the ball and the cap. The end play should be 0.6 ± 0.2 mm (.02 ± .01 inch). Adjust the end play, if necessary. The correct procedure is in the Operation and Maintenance Manual for the 24H Motor Grader. The Media Number is SEBU6970-07.

Check the torque on the eight bolts that hold the ball in place. The correct torque is 900 ± 100 N·m (664 ± 74 lb ft).

When assembling the drawbar to the bolster tighten the eight bolts to a torque of 1800 ± 200 N·m (1328 ± 148 lb ft).
