Service Magazine SEPD0788, 13 June 2005, "The Load Control Valve (Drift Reduction Valve) for the Boom Is Improved". Disregard this information. Refer to the article that follows.

Description of Change: A new load control valve gp improves the controllability of boom. The new valve prevents the selector spool from sticking in the valve body and becoming locked in place by an increase of the hydraulic pressure. The new valve allows the spool to shift smoothly when the control lever is activated.

Adaptable To: The new 264-9963 Load Control Valve Gp replaces the former 250-2578 Load Control Valve Gp. The new load control valve is effective with the machines that are listed in Table 1. The new valve is adaptable to the models that are listed.
