b) Turn the crankshaft clockwise (as seen from the front of the engine) until a 3/8"-16 NC bolt (1) can be installed through the timing hole in the flywheel housing and into the hole in the flywheel. Never turn the crankshaft backward to install the bolt in the flywheel. 2. Check to see if both rocker arms (2) for the No. 1 piston can be moved backward and forward by hand. The No. 1 piston is at the top center compression position when the bolt is installed in the flywheel, and both rocker arms for No. 1 piston can be moved backward and forward. If both rocker arms can not be moved, the No. 1 piston is not at the top center compression position. Remove the bolt from the flywheel. Turn the crankshaft clockwise (as seen from the front of the engine) one full turn (360°) and install the bolt again. 3. Remove plug (3) from the timing gear cover. Loosen the bolt that holds the accessory drive gear to the shaft. 4. Loosen nuts (5) that hold the accessory drive to the timing gear plate.5. Use a hammer and punch to hit the bolt and loosen the accessory drive gear from the shaft.
Remove the bolt from the accessory drive shaft but do not remove the bolt from the washer or accessory drive gear. Be extra careful not to let the washer and bolt fall into the timing gear cover.

Make sure the No. 1 piston is at top center compression position and the timing bolt is installed in the flywheel. 1. Turn the accessory drive shaft until tool (A) can be installed with the dowel holes in tool (A) in alignment with dowels (1) on the accessory drive housing. Use two of the bolts that are used to hold the fuel injection pump in place to hold tool (A) in position. 2. Make sure the O-ring seal is in position on the front of the accessory drive housing. Use a 3/4" deep well socket (3) to hold the accessory drive bolt and washer in place. Put accessory drive housing (2) in position on the timing gear plate while the bolt is started in the accessory drive shaft. Do not tighten the bolt at this time. 3. Install three nuts (4) that hold the accessory drive housing to the timing gear plate.4. Tighten the bolt that holds the accessory drive gear to a torque of 110 5 lb.ft. (149 7 N m). 5.
