BELT TENSION

Generator is used to adjust drive belt tension. For belt routing (Scheme 6) Check belt tension using Burroughs Tension Gauge (BT-33-73F) at longest belt run. (Scheme 7) Adjust belt tension if necessary. See BELT TENSION SPECIFICATIONS table.

BELT TENSION SPECIFICATIONS

BRUSHES

  1. Brushes should slide smoothly in holders. Replace brushes if damaged or worn. See «GENERATOR SPECIFICATIONS»(ref-167925-S06412177982004102500000) .
  2. If exposed brush length is less than minimum, replace brushes and brush holder assembly. Install new brush springs when replacing brushes.

DIODES

Information for testing diodes, not available from manufacturer.

ROTOR

  1. Check rotor for open field windings by using an ohmmeter across slip rings. Rotor resistance should be within specification. See «GENERATOR SPECIFICATIONS»(ref-167925-S06412177982004102500000) . If resistance reading is not as specified, replace rotor.
  2. Check rotor for grounded field windings. Using an ohmmeter, check for continuity between slip ring and rotor. Continuity should not be present. If continuity is present, replace rotor.
  3. Check slip rings for wear or pitting. Turn rotor/slip rings on lathe if necessary. If slip rings are rough or scored, replace rotor.

STATOR

Information for testing stator, not available from manufacturer.

VOLTAGE REGULATOR

Information for testing voltage regulator, not available from manufacturer.
