Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
in General Information.Important : Never engage the starter motor in order to rotate the engine when the injection pump is removed as severe engine damage will occur. With the injection pump removed, the pump driven gear could jam in the front housing by engaging the starter motor, resulting in a sheared crankshaft or camshaft gear key and possible valve train damage. Always bar the engine over by hand in order to avoid internal engine damage.
Important: Be sure that the locating stud (1) on the injection pump hub goes into the slotted/elongated hole in the driven gear.
Tighten
Tighten the nuts to 40 N·m (30 lb ft).
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Important: None of the driven gear bolts should be torqued until all of the bolts are installed. This will allow for proper alignment of all of the bolt holes.
Tighten
Tighten the bolts to 25 N·m (18 lb ft).
