Repair and Replacement
1. Commutator - Clean with a soft, clean cloth.
2. Replace any damaged or cracked brush holders or
brushes worn to less than 11/16" (17 mm) in length or
to the line marked on the brush.
3. Test the insulation between the core and the commu-
tator segments and shaft with a circuit tester. If conti-
nuity is indicated, the insulation is defective and the
armature must be replaced.
4. With the brushes removed, using a DVOM, check the
field coils for continuity between ‘F1’ and ‘F2’ and ‘DF’
and ‘F1’. If an open circuit exists, replace the field
coils. Check for continuity between all four terminals
and the frame (outer shell). If continuity is indicated,
the field coils are grounded against the frame and the
field coils must be replaced.
5. Clean all parts to be reinstalled and reassemble in the
reverse order of disassembly. Tighten bolts and nuts
to the following values:
• 4 mm - torque to 15 - 21 in. lbs. (17 - 24 kg/cm)
• 5 mm - torque to 30 - 43 in. lbs. (35 - 50 kg/cm)
• 6 mm - torque to 52 - 74 in. lbs. (60 - 85 kg/cm)
• 14 mm - torque to 33 - 40 ft. lbs. (45 - 55 Nm)
Tighten terminal nuts to the following torques:
• F1 - F2 - torque to 43 - 52 in. lbs. (50 - 60 kg/cm)
• DF - torque to 26 - 35 in. lbs. (30 - 40 kg/cm)
BATTERY VOLTAGE TEST
Battery voltage can be checked using a voltmeter. Attach
the negative (-) lead of the DVOM to the ground terminal
of the battery. The positive (+) lead is then attached to the
positive battery terminal. The voltage reading obtained
should be 12 volts or above. If the reading is below 12
volts, the battery requires either charging or replacement.
Hydrogen gas formed during bat-
tery charging is explosive and can
cause personal injury or death.
Avoid any electrical spark or open flame near bat-
tery.
NOTICE: If the temperature of the battery or the
ambient temperature is below 60° F (15° C), the
capacity of the battery will be less. It will require
more time to charge. A cold battery will build up
voltage and more rapidly reduce the charging rate.
NOTICE: Batteries that are new or have been stored
must be fully charged before being tested or placed
in vehicle.
Do not overcharge battery.
STORAGE OF BATTERY
A battery that is removed from service for storage must
be cared for as follows:
For battery removal see ‘Battery Removal’ in SAFETY
section. Charge fully. Cover terminals with petroleum jelly
to prevent oxidation (use commercially available battery
protectant when installed in vehicle). Store in a cool place
not below 32° F (0° C) or above 80° F (27° C) Battery
should be charged every 30 days using a 2 amp trickle
charger.
DVOM (DIGITAL VOLT OHM METER)
The DVOM shown (Ref. Fig. 9) is representative only, the
actual model may vary depending on availability, and is
available through the Service Parts Department as P/N
27481G01. For the purpose of this section, the red probe
(+) and black probe (-) are used. Any DVOM may be
used, however the controls, displays, accuracy and fea-
tures may vary depending on the make and model.
Always follow the meter manufacturer’s recommenda-
tions and instructions for the use and care of the meter.
