PROBLEM

Show/hide table

The existing 308-3212 Wheel can fail either by cracking, wheel bearing bore damage, or spline wear on certain 777G Off-Highway Trucks.

The wheels need to be inspected at PCR or CCR rebuild and be replaced if they do not fall into the reusability guidelines.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

The material of the 308-3212 Wheel has been improved. The new Wheel part number is 567-0369 replacing the older 308-3212. Improvements have also been made to the inner Wheel Bearing Bore by adding more material to strengthen the bore area and improve life of the wheel.
Wheel material improvements will help with wheel cracking, bearing bore damage, and wheel brake disc spline wear.

The 567-0369 Wheel is effective with all the products after the listed serial numbers.

During a CCR or PCR rebuild, inspect the 308-3212 Front Wheel Splines for wear and reusability. Follow the Reuse and Salvage Guidelines for your model 777G Off-Highway Truck for gear and spline teeth wear.

If your part is not able to be reused due to spline wear and needs replaced, this service letter can be applied. Photos of the gear teeth wear along with photos of the date code are required with the claim.

Please use the below pictures as an example for required photos on Wheel Spline Wear and Wheel Cracking.
Bearing Bore damage is evident.
