6.2 Mounting on engine
For tightening torques refer to section 6.2.5
6.2.1 Assembly shape IM B35
(see fi gure on the right)
Caution! Before proceeding with assembly check that the couplings
(both on generator and engine) are in order and perfectly clean.
• Remove the protective grids (6).
• Fasten the shield (1) to the engine (after having removed it from the
alternator).
• Apply the tie rod (2) that anchors the rotor axially by screwing it onto
the external section of the engine shaft.
• Anchor the complete generator assembly (i.e. stator and rotor) to the
fl ange(1) using the 4 self-locking nuts (3).
• Check that the cone couplings of rotor and engine have made con-
tact
by hammering the rotor axially with a plastic mallet and block.
• Lock axially the rotor by turning the self-locking nut (4) on the tie rod
(2).
Caution! Before fastening the nut check that part of the threaded
section of the tie rod enters the rotor thereby obtaining a sound
hold.
• Check that exciter rotor and stator are perfectly aligned.
• Mount the assembly on antivibration plugs (5) making sure that
engine and generator are level.
• Replace the grilles (6) and fi t the plastic cap (7).
6.2.2 Dismantling shape IM B35
For dismantling follow in reverse the instructions provided in section
6.2.1.
