Heat Sink Mounting.
(3)
Install insulating bushings (26) into heat sinks
(21 and 22). Position heat sinks in the slip ring end housing
(31) and fasten with two capscrews (15), lockwashers (16),
guard washers (17), and insulating washers (18). Do not
tighten (fig. 7-68).
(4) Install capacitor (25), clamp (24), and three
screws (23).
(5) Replace the gasket (36) and regulator housing
(37).
NOTE
Be sure mating surfaces of heat sinks,
terminals, and terminal screws are clean and
free of paint to ensure a good electrical
connection.
(6) Install the regulator lead wires to the
terminal bolts. Red wire goes on the positive terminal
screw (19), and black wire goes on negative terminal screw
(20).
(7) Install terminal bolts through heat sinks, slip
ring end housing (31), and regulator housing (37). Ensure
that red and black regulator leads (fig. 7-69) are properly
routed through cutaway section of end housing (31).
(8) Install two nuts (38) on terminal screws (19
and 20). Tight en nuts. Loosely install two washers (39) and
nuts (40).
(9) Tighten lower heat sink screws (15) and check
all leads for proper routing. Ensure that no lead is pinched
under heat sink.
(10) Reinstall stator and terminal nuts. It is
advisable to aline stator (14) and housing (31) by
temporarily installing the through bolts (5).
(11) Press drive end bearing (8) into housing (7),
and reinstall bearing retainer (9) and four screws (10).

Installing Regulator Leads.
(12) Press drive end housing (7) and bearing (8)
onto rotor shaft.
(13) Install rotor (12) and housing (7) assembly
into stator (14) and slip ring end housing (31) assembly,
being sure to aline mounting ears.
(14) Install three through bolts (5), washers (6),
and self-locking nuts (32). Tighten nuts to 50-60 lb.-in.
Place a small amount of SRI 2 grease in housing and
reinstall the metal dust cap (33) by carefully pressing it
into place.
(15) Install diode trio and three nuts (fig. 7-65).
(16) Insert outer brush and spring assembly (44)
into the housing (37), and compress the brush spring. Use
a small screwdriver or similar tool. While holding the
spring compressed, insert a pin through the hole in the
rear of the housing so the spring will be held in a
compressed position. (A suitable pin can be made from a
piece of 1/16-inch drill rod.) Install and compress the
remaining brush and spring assembly (44) in a similar
manner. Hold the spring in a compressed position by
pushing the pin farther into the housing (fig. 7-70).
