Maintenance
Schedules
A regular preventive maintenance schedule will ensure peak
performance, minimize breakdowns and maximize generator life.
The schedule listed below is a guide for operating under standard
conditions. Specific operating conditions may require reduced or
increased maintenance intervals. Also, if there is a different or more
specific schedule for your generator than the schedule provided below,
it will be included as a supplement to the manual package.
Every Day
Visually check generator bearing housings.
Check the operating temperatures of the generator stator windings.
Check the control panel voltmeter for proper stability and voltage
output.
Monitor the power factor and generator loading during operation.).
Every Week
Visually inspect the bearing exterior for dirt, and clean if necessary.
Inspect any generator air filters for build up of contaminants, and clean
or replace as required.
Every 2000 Hours or 6 Months of Operation
Remove generator outlet box cover. Visually inspect the stator output
leads and insulation for cracking or damage. Check all exposed
electrical connections for tightness. Check transformers, fuses,
capacitors, and lightning arrestors for loose mounting or physical
damage. Check all lead wires and electrical connections for proper
clearance and spacing.
Clean the inside of the outlet box, air screens, bearing housings, and air
baffles with compressed air and electrical solvent if needed.
With generators that have ball or roller bearings, check machine
vibrations and bearing condition with a spectrum analyzer or shock
pulse.
Regrease the regreasable-type bearings. With generators that have
sleeve oil bearings inspect bearing oil for proper levels and clarity.
Every 8000 Hours or 1 Year of Operation
Check insulation resistance to ground on all generator windings,
including the main rotating assembly, the main stator assembly, the
exciter field and armature assemblies, and the PMG assembly.
Check the space heaters for proper operation.
Check the rotating rectifier connection tightness.
With generators that have sleeve oil bearings, replace the bearing oil.
NOTE: For specific lubrication instructions,
always refer to the bearing lubrication
sheet that came with your manual or the
lube plate on the generator.
