Sundstrand Sauer Danfoss Series 90 End Cap Gasket Change

On service bulletin SB1989-009 it discusses the change in schematics of the endcap on a 55cc pump that uses the same part number on the gasket, for the twin port and axial port endcap choices.
The old style endcaps will no longer be available and will not be available for spare parts either. The endcaps can be use on older models. When using new endcaps, you must use new gaskets.
The old style end cap gaskets are available on service parts to fix earlier models.
