A Checklist for Keeping Diesel Generators in Good Working Order

A well maintained industrial generator (also known as a genset) may survive for decades. Despite the fact that a generator has few moving parts, it has sensitive components that must be maintained on a regular basis. Complete genset maintenance necessitates a variety of procedures to be carried out on various schedules. A simple checklist for diesel generator maintenance on a daily, monthly, semiannual, and annual basis is provided below if you require a plan for executing these steps.

Measurements Taken Every Day

Diesel generators should be subjected to the following daily checks:

General examination – Look for loose components, evidence of corrosion on parts, traces of carbon, and dust accumulation on the generator.
Check the coolant heater for signs of wear and make sure it’s firmly in place.
Check the oil level and, if necessary, apply more oil.
Check the fuel level and add more gasoline if necessary.
Charge-air piping inspection – double-check that the charge-air piping is properly attached to the radiator and that it shows no indications of wear.
The procedures outlined above are frequently carried out by maintenance workers. They can also be done as part of a regular service agreement by generator professionals.

Measurements every week

On a weekly basis, diesel generators should get the following measures:

Air cleaner inspection – Inspect the air cleaner for dirt and clean it as needed.
Battery charger inspection – Inspect the float voltage reading on the battery charger and make any required adjustments.
Drain the water from the bottom of the fuel filter housing with the fuel filter drain.
Drain the water from the bottom of the fuel tank until you can see the diesel fuel.
Generator technicians at many institutions execute the weekly checks on a generator maintenance checklist. If they are performed by building maintenance employees, they should be trained in generator maintenance.

Monthly Indicators

On a monthly basis, the following checks should be done on diesel generators:

Coolant concentration check – Using a hydrometer, take a sample of the coolant and verify its concentration using the manufacturer’s service handbook.
Drive belt tension check – Inspect the belt for symptoms of wear and correct tension.
Drain the condensate from the condensate trap using the exhaust condensate drain.
Examine the connections for looseness and corrosion and verify the charge on the starting battery.
Because the right coolant concentration in an outdoor generator can be impacted by environment, the coolant concentration check should be performed by a generator technician who specialises in emergency power equipment in the Carolinas.

Measurements every six months

On a semiannual basis, the following checks should be done on diesel generators:

Whether or not the genset has been utilised in a non-simulated power outage, it is necessary to change the oil and oil filter.
Regardless of whether the genset has been utilised in a non-simulated power loss, the coolant filter should be replaced.
Cleaning the crankcase breather – Clean the crankcase breather according to the manufacturer’s service instructions.
Change the air cleaner element, regardless of the amount of trash accumulated.
Radiator hose inspection – Inspect the radiator hoses for signs of wear and verify their connections.
Fuel filter replacement – Regardless of the degree of silt collection, replace the fuel filter.
The steps outlined above should be carried out by generator specialists.

Annual Evaluations

The cooling system of the genset should be thoroughly cleaned once a year.

Conclusion

To keep a diesel generator in good working order, do the steps outlined above. You may prepare your facility’s generator for the next power loss by including them in a generator maintenance checklist.
