Reference: Service Magazine, SEPD0194, 21 February 1994, "Improved Screen Used In The Brake Oil Cooler"

The new 224-3895 Screen As is a direct replacement for the former 6E-6640 Screen As. Use the new screen in the following groups: 170-3622 Hydraulic Oil Cooler Lines Gp, 149-3067 Power Train Oil Lines Gp, 125-5811 Hydraulic Oil Cooler Lines Gp and 125-5861 Hydraulic Oil Cooler Lines Gp. The new brake cooling screen has a thicker screen and a wire wrap. The new screen also has a welded retainer at both ends that will help improve the fatigue life of the screen element.

Note: Install a 9S-4181 Plug in the 224-3895 Screen As.
