NOTE: There are two different design vibration dampers used:
• Viscous damper (A) for certain marine engines and some automotive applications
• Rubber element damper (B) for all other applications
As previously discussed in the fuel system, replacement of the gear housing or the timing pin assembly necessi
tates a realignment of the pin assembly on the housing to correspond to TDC for Cylinder Number 1. Refer to Procedure 7-20 for replacement instructions.
