And Install Flywheel
Start By:a. separation of generator The following photos show a TYPICAL EXAMPLE and are not an exact representation of the 3208 Generator Set. However, the procedures are the same. 1. Fasten a hoist to flywheel (1) with tool (A).2. Remove the bolts, and remove flywheel (1) from the end of the crankshaft and the flywheel housing. The weight of the flywheel is 28 kg (62 lb.). 3. If necessary, remove ring gear (2) from the flywheel. The following steps are to install the flywheel. 4. If necessary, heat ring gear (1) to a maximum temperature of 204°C (400°F), and install it on the flywheel. Make sure the ring gear is against the shoulder of the flywheel and the part number is toward the engine. Make sure the correct sealant is put on the bolt threads. The holes for the bolts in the crankshaft flange are drilled through so the holes are open to the oil in the engine. Leakage along the bolt threads can be the result if the correct sealant is not used.
When a new flywheel is installed, check the thickness of the new flywheel at the bolt holes in relation to the thickness of the old flywheel. Install the correct length bolts so they will be fully engaged in the crankshaft flange. Bolts that are too long will make contact with the block on the back side of the crankshaft flange and pull the crankshaft back. This will cause the crankshaft thrust bearing to fail.
5. Install a 5/8"-18 NF guide bolt (2) in the end of the crankshaft.6. Fasten a hoist to flywheel (3) with tool (A). Make sure the dash mark on the flywheel and the dash mark on the crankshaft are in alignment. Put flywheel (3) in position on the guide bolt and the end of the crankshaft.7. Put 5P3413 Sealant on the threads of the flywheel bolts. Install the flywheel bolts, and remove the guide bolt. Install the last flywheel bolt, and tighten all the bolts to a torque of 90 7 N m (66 5 lb.ft.).End By:a. connection of generator
