CAUTION
Do not tap on stator assembly windings when seating stator on adapter plate.
(3)
With stator assembly (18) shell seam down, position stator assembly over rotor and onto adapter plate
(27). Using a soft faced mallet, tap on end of stator assembly shell to seat on adapter plate.
(4)
With the vertical portion of the "Y" positioned at the bottom, align bearing bracket (16) to the stator
assembly lip and the stub shaft with inner race of bearing (29).
CAUTION
Do not attempt to seat bearing bracket to stator assembly by tightening thru
bolts (28). Seat bearing bracket by tapping in the center of the bracket.
Tightening the thru bolts or tapping in other than the center of the bracket
could cock the bearing or fracture the molded bearing support and slip ring of
the rotor.
(5)
Using a soft faced mallet, carefully tap on center of bearing bracket (16) until bracket is fully seated on
shell of stator assembly (18) and stub shaft is seated in bearing (29).
CAUTION
The top surfaces of bearing bracket (16) and adapter plate (27) must be
parallel to prevent twisting. If bracket and plate are not parallel, alternator can
be severely damaged.
(6)
Insert thru bolts (28) through bearing bracket (16), install keps nuts (9), and tighten nuts diagonally to
75 lbs-in. (8.5 Nm) making sure bottom of bracket remains perfectly straight.
(7)
Secure support bracket (17) and ground strap (15) to bearing bracket (16) with washers (14), bolts
(13), washers (12), lockwashers (11), and nuts (10).
(8)
Ensure a clearance of .006 in. (.15 mm) exists between stator and rotor windings, and rotor turns
freely with no interference.
(9)
Install brushes (8) in bearing bracket with brush caps (7).
(10) Connect stator wires and brush wires (6) with screws (5) and remove tags.
(11) Install alternator guard (4) on alternator with washers (3), lockwashers (2), and screws (1). Cross
tighten screws to 6 lbs-ft (8.2 Nm).
(12) Install engine/alternator assembly, refer to paragraph 5.9.b.
