DIESEL BIND PUMP METER VALVE NO START/STALL INFORMATION

IT IS POSSIBLE FOR THE METERING VALVE ARM ON SOME ROOSA-MASTER INJECTION PUMPS TO CONTACT AND BIND ON THE HOUSING AFTER THE HEAD AND ROTOR HAVE BEEN REMOVED AND REINSTALLED. IF THIS CONDITION IS ENCOUNTERED WHEN CHECKING FOR METERING VALVE FREE MOVEMENT, LOOSEN THE HEAD LOCKING AND HEAD LOCATING SCREWS. ROTATE THE HEAD TO PROVIDE CLEARANCE FOR THE METERING VALVE ARM. RE-TORQUE THE SCREWS TO SPECIFICATIONS.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
