Notice: Never rotate the engine with the starter, the starter location engine rotation fixture, or with the wrench from the front of the engine with the fuel injection pump removed. The loose fuel pump drive gear could become lodged in the front cover and cause gear tooth distress and shear the camshaft drive gear. Align the camshaft gear timing marks before installing the fuel injection pump drive 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: Align the timing marks. Be certain the mark on the fuel injection pump gear is aligned with the mark on the camshaft gear. For the proper timing of the fuel injection pump, the cam gear timing mark must be in the 12  o'clock position. Rotate the crankshaft to bring the cam gear timing mark up to the 12 o'clock position.

Tighten
Tighten the bolts to 25 N·m(20 lb ft).
