I've installed new bearings in my D6 8U steering clutch assembly but one side has a smaller washer (1A1450) than the other side. I ordered a new washer thinking it would be larger and completely cover the bearing to prevent grease from oozing out but it's the smaller washer that leaves part of the bearing open as well. I've attached pictures that show how one washer completely covers the bearing and the other side leaves an opening. The service manual mentions later tractors had some changes. Just looking for some follow up before I re-install since removal and install is a lot of work.

Thanks.

It’s normal for the D6 8U steering clutch assembly to have different washer sizes on each side, especially on later tractors where Caterpillar revised the design—one side’s smaller washer (1A1450) intentionally leaves part of the thrust bearings exposed to allow grease to purge and prevent excess pressure from damaging the seals, while the other side’s larger washer acts as more of a shield. As long as the parts match the service manual for your serial range, the smaller washer isn’t a defect, and reinstalling it that way will ensure proper lubrication and longevity of the 6056 M bearings without trapping grease.
