Chrysler Windsor C-71 1956 - Assembling the Generator

CHRYSLER SERVICE MANUAL
ELECTRICAL SYSTEM—17
of V&2 inch, the full width of insulation. Metal
particles are sometimes embedded in grooves
following undercutting and should be removed.
24. REPLACING FIELD COILS
To replace field coils, a pole shoe screwdriver,
such as Tool C-3078, should be used to prevent
damage to screws and to assure proper tighten-
ing when installing coils. Pole shoes that are
loose will rub armature core, causing loss of
efficiency and damage to armature.
25. REPLACING BRUSHES AND SPRINGS
Brushes that are oil soaked or worn to V& length
of a new brush should be replaced. Sand new
generator brushes to fit contour of commutator.
With new type brush holder, it is difficult to
measure spring tension (which must be done
after generator is assembled). It is suggested
that new springs be installed when brushes
are replaced.
26. ASSEMBLING THE GENERATOR
a. Standard Generators
Soak felt washers and Oilite bushing in clean
engine oil. Pack ball bearing about half full
with high temperature non-fiber bearing lubri-
cant. Compress felt slightly to remove oil be-
fore installing.
(Refer to Figs. 7 and 8.) Assemble drive
end parts on armature before installing it in
generator. Do not grip core too tightly in vise.
Install retainer over snap ring before pressing
bearing and end frame assembly on shaft. In-
stall suitable sleeve over armature shaft so
that pressure is applied to inner race when
pressing bearing on shaft.
b. Accessory Equipment Generators
On generators used with air conditioning equip-
ment, install armature and drive end assembly
in generator field frame. Install commutator
end plate and through bolts. Place felt and
shield in commutator end plate and press bear-
ing on shaft, applying pressure to inner race.
Install shield.
c. Testing After Assembly
The generator should be tested before it is in-
stalled on car. If proper bench test equipment
is not available, it is possible to motor test
generator. A generator that will motor freely
with specified voltage applied will, in most
cases, operate properly when driven as a gen-
erator.
27. MOTORING TEST
Connect a carbon pile rheostat and test am-
meter in series with positive post of 12-volt
battery and generator armature terminal post.
Connect a jumper lead from field terminal post
to ground. Connect a jumper lead to battery
negative post and generator frame. This will
cause armature to rotate as a motor. Adjust
battery voltage to 10 volts. The reading on test
ammeter should be 3.4 to 3.9 amperes with
armature turning smoothly.
28. INSTALLATION
Place generator in position and install attach-
ing bolts. Adjust drive belt tension at gener-
ating strap so there is a deflection of *4 inch
with 9 to 12 pounds pressure. Refer to Fig. 4,
Cooling System, Section. V.
CAUTION
Be sure condenser used for radio interference
is properly attached to armature ("ARM")
terminal post.
REGULATORS
The current and voltage regulator is designed
to operate only in 12-volt, negative ground
electrical system.
NOTE: Do not attempt to adjust unit unless
proper procedures are thoroughly understood.
Otherwise, damage to entire electrical system
may result.
29. PREPARATIONS FOR TESTING
Disconnect battery before attempting to re-
move regulator assembly or to connect test
equipment. Do not connect test equipment. Do
not connect battery again until after regulator
removal and/or installation has been com-
pleted. Do not connect battery when installing
