Description of Change: New gaskets are being used in the prechamber groups on G3600 Engines. The new gaskets provide improved resistance to corrosion. The new gaskets also provide excellent characteristics for sealing. The new 219-6908 Gasket (1) is used with all one-piece prechamber groups. This gasket is also used in the lower location with all two-piece prechamber groups. The new 219-7009 Gasket (2) is used in the upper location with all two-piece prechamber groups.

This illustration shows a one-piece prechamber group (A). Items (B) are O-ring seals. Item (1) is the new 219-6908 Gasket . |
Illustration 2 | g00924989 |
This illustration shows a two-piece prechamber group (C)). Items (B) are O-ring seals. Item (1) is the new 219-6908 Gasket. Item (2) is the new 219-7009 Gasket . |
Adaptable To: The new 219-6908 Gasket is a direct replacement for the former 187-6613 Gasket. The new 219-7009 Gasket is a direct replacement for the former 187-6614 Gasket. The former gaskets are cancelled. The effectivity of the new gaskets is shown in Table 1. The locations of the gaskets are identified in Table 2.
