5-8. PERMANENT MAGNET ALTERNATOR MAINTENANCE - cont.
C. INSTALLATION.
1.
Apply loctite to threads of four screws (15, Figure 5-2). Install engine adapter (18) onto engine using
screws (15), lockwashers (16), and washers (17). Torque screws to 15 ft-lbs.
2.
Install stator (14) into engine adapter (18). Stator must be installed so that the alternator output leads (1, 2,
3, 4) are at the bottom, positioned for their exit through cover (5). Secure stator (14) using six screws (12)
and clamping ring (13).
WARNING
Rotor assembly (11) is held in stator (14) by magnets. Rotor will snap into place in stator when
installed. Use care to prevent injury to fingers.
3.
Hold rotor assembly (11) so that no part of your fingers will be between the rotor and stator (14).
Carefully insert rotor assembly (11) into stator (14). The rotor will cock slightly as it is drawn into the
stator and stick in place. Using a rubber hammer, lightly tap the high side of the rotor until it slams into
place.
4.
Apply loctite to threads of screw (9). Install screw (9) and washer (10). Torque screw to 15 ft-lbs.
5.
Using a feeler gage, check that clearance between rotor assembly (11) and stator (14) is 0.010 inch
(minimum) at all points. If clearance is less than 0.010 inch, remove rotor assembly (11) and reinstall.
6.
Feed alternator output leads (1, 2, 3, 4) through cover (5). Leads must exit cover without the possibility of
abrasion. Secure cover (5) using six screws.
