Recheck timing until specified timing is obtained. 12. After adjustment, grind the engine front plate mark to avoid any confusion with the original timing adjustment. CD30449 NOTE:
If the injection pump has to be removed from engine and reinstalled without any change, mark both the front plate and the injection pump flange to allow the reinstallation of injection pump at the same location. In case of repair or replacement of injection pump, perform again a dynamic timing. CD,FKM10429A,10-19-02MAY96 40 52
