Description of Change: A new gasket (1) is used under timing pin cover (4) in the flywheel housing cover group. The former gasket was made from a cork material. It could "relax" and allow the cover bolts (3) to loosen. The new gasket is made from an improved material that will not "relax" under normal operating conditions. This will help prevent the cover mounting bolts from loosening.
(1) New 2S1251 Gasket. (2) Timing Pin. (3) Bolts. (4) Cover.
Adaptable To: The new 2S1251 Gasket is a direct replacement for the former 7F7669 Gasket in the 1W9486 Flywheel Housing Cover Group.
