Basic diesel generator maintenance checklist
A basic diesel generator maintenance checklist is used to ensure that diesel generators provide good power quality. engineers and operators can follow this template guide when performing their inspections: perform physical and visual inspection of diesel generator. take photo evidence of leakage, damages, and defects. check the battery, oil and fuel condition. provide overall condition assessment of diesel generator. end inspection with a digital signature and timestamp.
What does this form include?
This form contains 5 sections:
Visual Inspection
- Overall condition/appearance of equipment (controls, leaks, loose wires)
- Fan belt tension and condition
- Fuel filter or sediment bowl
- Lubricating oil level and viscosity
- Coolant level and anti-freeze mixture
- Air filter
- Battery electrolyte level and specific gravity and load test
- Battery charging rate (trickle charger).
Operating Inspection
- Day tank pump and level switches if so equipped
- Operation of cooling thermostat or louvers
- Battery charging
- Alternator and regulator
Other Services
- Inspect of cooling system for leaks (pressure test), residue and operation. Check engine block heater.
- Inspect and clean generator brush holders and brushes
- Clean and inspect exciter
- Inspect safety shutdown devices. This includes simulated faults on low oil pressure cut-off, high water temperature cut-off, over speed cut-off and failed start.
- Inspect and clean engine/generator set control
- Run generator set (under load) to check voltage, check frequency, check instrument system and make adjustments.
- Clean and tighten electrical connections, clean crankcase breather, check and tighten mounting bolts and wipe unit clean
