Usage:
1. Fasten tooling (A) and a hoist to the flywheel as shown.
2. Remove two of the bolts (1) opposite each other that hold the flywheel to the crankshaft. Install two 7/16"-20 NF x 7 in. (178 mm) long guide bolts in the crankshaft.
3. Remove the remainder of the bolts, and remove flywheel (2) from the crankshaft. Weight of the flywheel is 27 kg (60 lb.).
4. Remove ring gear (3) from flywheel (2) with a punch and hammer.
Install Flywheel
1. Heat ring gear (1) to a maximum temperature of 204°C (400°F). Install the ring gear on flywheel (2) with the part number toward the engine when the flywheel is installed.
2. Install two 7/16"-20 NF guide bolts (3) opposite each other in the end of the crankshaft.
3. Fasten tooling (A) and a hoist to the flywheel. Put the flywheel in position on the guide bolts, and make sure offset hole (4) [identified by dashmark] and the mark on the end of the crankshaft are in alignment.
4. Install all but two bolts in the flywheel. Remove tooling (A) and the guide bolts. Install the remainder of the bolts in the flywheel. Tighten the bolts to a torque of 90 ± 7 N·m (66 ± 5 lb.ft.).
5. Use tooling (B) to measure the face runout and bore runout of the flywheel. The face runout and bore runout must not be greater than 0.15 mm (.006 in.) total indicator reading. See Specifications for 3204 Industrial Engines, Form No. SENR3003, for the correct procedure to measure the face runout and bore runout of the flywheel.
