Existing dealer parts stock of 443-8879 Spacers and 443-8878 Rings needs to be inspected. These spacers and rings are for use on certain 794 AC, 796 AC, and 798 AC Off-Highway Trucks. Some of these spacers and rings may not be within Caterpillar design specifications. If the parts are out of specification they may cause premature wear in the nose-cone (rear-axle) bearing.
