(1) Flywheel Pilot Bore (2) Surface
Remove all dirt, burrs, and paint from the contact surfaces of the generator supports and the base. Remove the protection material (compound) from flywheel pilot bore (1) and from surface (2). There should be no protection material that makes contact with the coupling. All contact surfaces of the engine, the coupling, and the generator must be completely clean.

(3) Dial Indicator Group (4) Crankshaft Pulley
In order to manually rotate the engine, remove the timing pointer's cover from the engine's flywheel housing. Install dial indicator group (3). Refer to Illustration 2. The tip of the indicator must touch the face of crankshaft pulley (4). Use a bar between the flywheel and the flywheel housing in order to push the crankshaft toward the flywheel. This will remove all the end play. Put the dial indicator in the ZERO position. Move the crankshaft to the most forward position. Make a record of the total indicator reading (TIR). The TIR is the end play of the crankshaft.

(5) Shim Pack
Illustration 4 g00616734
(6) Plate Assembly (7) Bolts
Do not run the generator set unless the plate assembly has the correct clearance. If the plate assembly does not have the correct clearance, damage can occur to the engine and/or generator.
Before installation, temporarily position plate assembly (6) in the bore of the flywheel to check for clearance. There must be clearance between the plate assembly's outside diameter and the flywheel bore's inside diameter. The plate assembly (6) can be a single solid plate or the plate assembly can be numerous flexible plates.
Install a full shim pack (5) and plate assembly (6) on the generator with bolts (7). Tighten the bolts to the torques that are shown in Table 2.
Table 2
REQUIRED TORQUE    
Engine     Torque    
D379, G379, D398, G398, D399, G399    
505 45 N m (372.0 33.0 lb ft)    
All other engines     Standard torque    Note: Incorrect torque of bolts (7) can distort the shims which may reduce rotor bearing end play. When the shims are assembled to the drive coupling, the bolts (7) must be tightened to the correct torque.Note: The total thickness of shims (5) must not cause a reduction of crankshaft end play. When the generator is installed, the total thickness of shims (5) must not cause bending of plate assembly (6) .

(8) Guide Bolt
Install guide bolt (8) in the flywheel.
Put the generator in position on the engine.
Illustration 6 g00295971
(9) Bolts (10) Bolts
Install bolts (9) and (10). Tighten bolts (9) and (10).
Illustration 7 g00295967
Install dial indicator group (3) in order to measure crankshaft end play at crankshaft pulley (4). In order to remove all end play, place a bar between the flywheel and the flywheel housing. Push the crankshaft toward the flywheel. Put the dial indicator in the ZERO position. Move the crankshaft to the most forward
