| SBW35-018 | 2020-12-30. Service bulletin. POWER TRAIN. Western Star Service Bulletin for Axle Flange Gasket Replaced with O-Ring. Daimler Trucks North America has released a new axle shaft to hub rubber O-ring (part number 11-30728-000) as a replacement for the paper gasket (part number 11-14418-000). The new O-ring will provide better sealing and is reusable. It is quicker and easier to use compared to the paper gasket, because using a paper gasket requires cleaning the hub when the axle shaft is removed. |
