A new 107-4347 Wear Ring is available for front suspension groups. The new 107-4347 Wear Ring, when used with a 9X-7450 U-cup Seal, will reduce friction in the front suspension group. The reduced friction will help eliminate vibration caused by tire bounce.
The new 107-4347 Wear Ring is a direct replacement for the 1U-4778 Wear Ring or 8T-7692 Ring in the 1U-4777, 116-3092, 107-2200 and 4Z-6168 Front Suspension Groups used in the 772B (64W155-Up) Tractors and 773B (63W770-Up) Trucks. One 9X-7450 U-cup Seal replaces the 8T-3539 and 8T-3540 Seals in the same front suspension groups.
