Illustration 1	g01138041

1. Remove top bolt (1). Install Tooling (A). Remove remaining bolts (1).

2. Fasten Tooling (B) and a suitable lifting device to flywheel (2). The weight of flywheel (2) is approximately 40 kg (85 lb).

   Note: Engines equipped with a Rear Power Take-Off RPTO will need to have Tooling (C) installed. Tooling (C) will hold the RPTO gear tight against the end of the crankshaft during the removal of the flywheel.

3. Remove flywheel (2).

4. Use a hammer and a punch to remove the flywheel ring gear, if necessary.

Installation Procedure

1. Install flywheel (2) in the reverse order of removal.

   1. Raise the temperature of the flywheel ring gear. Do not use a torch to heat the flywheel ring gear. Install the flywheel ring gear on the flywheel. Position the flywheel ring gear with the part number toward the crankshaft. Allow the flywheel ring gear to cool. Use a soft hammer to seat the flywheel ring gear against the shoulder of the flywheel.

   2. Apply Tooling (D) to the threads of bolts (1).

   3. Tighten bolts (1) evenly to a torque of 300 ± 40 N·m (221 ± 30 lb ft).

   4. Check the flywheel runout. Refer to Testing and Adjusting, "Flywheel - Inspect".
