5-27 Alternator reassembly and reinstallation
a.
General. Reassembly is the reverse of disassembly procedure.
b.
Specific instructions.
(1) Assembling pulley to shaft. Secure rotor in a vise only tight enough to permit tightening shaft nut to 40-60
lb ft.
(2) Installing drive end frame with rotor into slip ring end frame. Remove tape over bearing and shaft, make
sure shaft is perfectly clean. Insert a pin through holes to hold brushes up. Install slip ring end very carefully to avoid
damage to seal. Tighten through bolts. Remove brush retaining pins to let brushes contact slip rings.
Section VIII. Starting Motor and Solenoid
5-28 General
a.
The starting motor is a heavy duty, 12 volt, submersion, fungus and corrosion resistant, solenoid operated,
enclosed shift type engine starter with eight (or four) brushes retained by four brush holders. Figure 5-8 is a typical unit
used on this winch; minor variations such as the number of brushes may be noticed on disassembly.
b.
The drive clutch is a Sprag overrunning type. The overrunning clutch prevents overspeeding of starter
during intermittent engine firing by allowing pinion to turn faster than armature.
c.
The principal components of starter are frame, field coils, armature, commutator, brush assembly, drive
housing, shift lever, and solenoid plunger.
NOTE
Refer to Figures 5-4 and 5-5 for the following steps.
(1) Disconnect field coil connector from solenoid motor terminal and remove solenoid mounting screws.
(2) Remove end frame cap screws.
CAUTION
While removing field frame, do not drop the armature out of field frame or allow it to fall from lever
housing.
(3) Remove end frame from field frame.
(4) Remove capscrews between field frame and lever housing.
(5) Remove field frame.
(6) Remove nose housing attaching bolts and separate nose housing, from lever housing.
