Service Magazine, SEPD0812, 28 November 2006, "Adding Weld Can Prevent Further Cracking of Rims ". Disregard this article. Use the information that follows.

Certain wheel rims can crack around the inner circle when the machines are used in heavy-duty applications and when foam-filled tires are used. For either situation, adding weld in the areas that are indicated in Illustration 1 can prevent cracking of the rim.

Note: This action is not for repairing base metal fatigue cracks in the wheel rims.

Note: The added welds should be a 5 mm (0.19 inch) fillet weld with 1.5 mm (0.06 inch) penetration.

Note: Welding must be accomplished without a mounted tire on the rim.

The affected wheels are listed below.

• 142-7490 Wheel

• 142-8759 Wheel

• 142-7485 Wheel

• 142-8731 Wheel
