Since mid-2007 GE Waukesha has produced all new CFR Octane and Cetane Units to meet European CE Mark compliance requirements. One of the changes to achieve this classification on Octane Units involves enclosing the valve train. Consequently additional instruction must be provided for users when setting the basic Rocker Arm Carrier Support height. The original system allowed direct access to the machined surface while the new system has interference to this measurement. The added guidance instructs the user how to compensate for this interference.
