Illustration 1 g00295804 (1) Fuel injection pump gear Bore ... 36.00 to 36.06 mm (1.417 to 1.420 inch)Tighten the four bolts to the following torque. ... 28 N m (21 lb ft)Tighten the two torx screws to the following torque. ... 9 N m (7 lb ft)Note: The torx screws retain the timing plate on the front of the gear. This plate is installed in the factory after the fuel injection pump timing has been accurately set to the top center position on the compression stroke of the No. 1 cylinder. If the timing plate is moved, the timing of the fuel injection pump must be set.Note: The crankshaft must not be turned unless the fuel injection pump gear is installed.Note: Do not remove the nut that retains the hub of the fuel injection pump to the shaft of the fuel injection pump. If the hub is removed, the hub must be positioned by correctly trained personnel and special test equipment.
