wheels.
General Information
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. Most ConMet aluminum hubs have a groove at the
end of the hub, where the O-ring can be installed. The O-ring is backwards compatible with those hubs that
have a proper groove. See Table 1 for compatible hub bill of material (BOM) numbers, and Table 2 for
compatible hub part numbers. The fastener torque values for this module remains the same.
