In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 8% 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
****Parts Stock ****
Remove all 318-3720, 318-3721, and 318-3722 Hump Hoses, without a red or orange liner, from dealer parts stock. The hoses that need to be removed from parts stock can be identified by the solid blue construction (see Image 1). Good parts can be identified by the presence of a red or orange liner inside the hose (see Image 2). This difference can also be discerned with the hoses still assembled to the machine by inspecting the edge of the hose.
