positions.
2. Place the rectifier in
position
in the body of the SRE bracket
and
fit fixing bolts, flat
and spring
washers and nuts.
3. Refit the brush gear and
fixing
screw.
Solder field diode
wires onto
brush gear terminal.
NOTE
:
It
is important that this
soldering operation be
carried
out
as quickly as possible as excessive
heat transference from the soldering
iron to the brush box moulding
could
warp the moulding
and
result in
restricting the free movement of the
brushes.
4. Solder main and
field
diode
wires onto their original
terminal
strips using a pair of long nose pliers
to grip the wire and act as a hea
t
dissipater. (Use 'Ersin'
60/40
'M'
Grade Solder or equivalent).
NOTE
:
When bending the diode
wires to link up with the
termination
strips, grip each diode wire at
its
base with a pair of long nose pliers
White or
Red
Lead
Green
Lead
and bend the wire into position with
the
fingers.
This will eliminate the
possibility of the wire becoming de-
tached from the silicon wafer inside
the
diode
assembly.

Ensure
6m/mxl 3m/m PVC sleeving pieces
on each of the two voltage regulator
mounting
posts
are in position and
are not damaged
,
renew if nec-
essary
using PVC sleeving cut to the
abovementioned lengths
(Fig.
25).
Place the voltage regulator in posi-
tion and fit pan head screws with
the
lock washer under the screw on
the right hand side of the regulator as
viewed from the front (Ref. figure
33). This washer is important as it
ensures a good earth return for the
regulator.
Regulator Wiring Terminations -
Green wire from regulator to
rear brush terminal.
White or Red wire to front or IND
brush terminal.

.
Place wavy thrust washer in
SRE bearing housing.
7. Compress brushes and insert a
3" x 3/32"
diameter
steel
pin
through the guide
hole
in the
SRE
head
with
approximately
1" of the pin protruding through the
rear face of the end head. This will
hold the brushes in a compressed
position whilst the rotor is being
fitted
.
8. Fit stator and solder the three
phase leads onto their original term-
inals.
Fit D.E. head and rotor assembly
.
Fit and tighten the three through
bolts evenly to a torque of 45
lbs/ins.
ensuring the end brackets are sitting
evenly on the stator lamination pack.
Withdraw brush gear retaining pin
.
Refit fan,
pulley,
spring washer
and shaft nut, tightening shaft nut
to specification.

.
Ensuring that the rotor turns
freely by hand, install on the vehicle
and observe
operation.
