New And Improved Gaskets In Front Housing Group And Accessory Drive Group
Usage:
3406 Truck Engines (92U)
Description of Change: The new gaskets used in the front housing group are made from a different material than the former gaskets. The new gasket material will provide improved sealing.
The accessory drive group gasket has been improved by adding a raised area (bead) to the cross section of the gasket. This will provide a better seal and reduce the possibility of oil leakage.
Adaptable As: The new gaskets used in the 4N3911 Front Housing Group are direct replacements for the former gaskets which are canceled. The chart shows the new and former gasket part numbers.
The part number of the improved gasket used in the 4N2264 Accessory Drive Group has not changed. It is the 4N3854 Gasket.
