Remove bolts (1) and flywheel (2) from the crankshaft. The weight of the flywheel is 72 kg (160 lb).3. If necessary, remove the ring gear from the flywheel with a hammer and punch.Install Flywheel
The ring gear must be installed with the chamfered side of the teeth up as shown in the inset of illustration A89844P1. This will put the chamfered side of the gear teeth toward the starter when the flywheel is installed so the starter will engage correctly.
1. Heat ring gear (1) to a maximum temperature of 320° C (608° F). Install the ring gear on the flywheel. 2. Install Tool (A) on the flywheel in the same position it was during removal. Install two 5/8 " - 18 NF guide bolts in the crankshaft if necessary.3. Make an alignment of timing mark (2) on the crankshaft and timing mark (3) on the flywheel. Hold the flywheel in position. Install the bolts that hold it to the crankshaft. Tighten the bolts to a torque of 205 27 N m (151 20 lb ft).
