Reassembly
Note: See Section 1.5 for specified torque values.
Engine and Rotor Hub Installation
1. To reinstall the engine/rotor hub at the flywheel,
tighten the four M8 x 35 screws at the specified
torque (see section 1.5) with a 13 mm socket
wrench. See Figure 10-17.

Rotor Installation
1. Apply antiseize compound to the keyed end of the
rotor shaft.
2. Guide the rotor on the alternator through stud and
push it towards the flywheel. See Figure 10-18.
Note: To prevent the rotor from falling, screw (without
tightening) the 27 mm nut of the seawater pump
shaft on the rotor through stud.

Stator Housing Installation
1. Guide the stator housing towards the engine
flywheel housing as far as possible. An O-ring in
the bearing seat hole stops it.
2. Ensure that the holes of the fixing stator housing
screws (M10 x 140) are aligned with the screws of
the engine flywheel housing.
3. Using a light uphand hammer, turn the stator
housing towards the engine flywheel until it enters
and the stator housing rear side supports the rotor
bearing. See Figure 10-19.

4. Screw (without tightening) the four M10 x 140
stator housing screws with a 17 mm socket
wrench. See Figure 10-20.
