How To Change Engine Oil In A Diesel Generator?

 

Changing the oil in a diesel generator is easy if you follow these instructions. Discover how to do it yourself!

Oil changes are essential for any vehicle, but especially so for generators. The oil helps keep the engine running smoothly, and changing it when it is due for service will extend its life.

Start the generator to get the engine warmed up. Your generator should be turned on and left running for a while so that the machine can warm up and the muck may loosen so the oil can drain along with it. Use work gloves because the engine and oil will be warm afterward. 

Remove the drain plug from the sump of the engine.

Shut down the engine. Next, remove the oil fill cap at the top of the machine. Then, unscrew the bolts holding the drain plug with a wrench at the bottom of the oil pan, place a bowl, and collect the draining oil. Loosen and remove the oil filter with a filter belt. See How to turn off the generator when the power comes back safely.

Note: Most 15kVA - 350kVA diesel engine generators use 16" bolts for their drain plug and use between 8L - 30L for oil changes.

Fix the drain plug firmly.

Verify you have tightened the drain bolt before replacing the oil filter, pulling the engine through the oil filler, and capping the filter with fresh oil. Learn how to change a diesel generator's fuel filter here.

Use a dipstick to measure the engine oil.

Add new oil to the engine. 

If you need to add more oil to an engine, pour it directly into the machine through the oil filler. It will ensure that the oil gets evenly distributed throughout the engine. Clean the generator set, start it briefly, and shut it down.

Start the engine.

Utilizing an oil dipstick, double-check the oil level and radiator coolant levels. Add more oil to the pan until the proper amount is present. If there isn't enough already similar, check the radiator's coolant level and start the engine.

What advantages can diesel generator oil changes offer?

Oil lubricates moving parts and guards against wear, keeping an engine operating smoothly. Changing the oil when it needs to be changed will increase engine longevity and decrease service downtime. Observe also: How long can a diesel generator run continuously?

Here's what you need to know.

If you own a generator, you should check the oil level daily. It will help ensure that the generator runs efficiently and safely. Make sure you change the oil filter along with the engine oil.

Why Change the Oil?

There are several reasons why you should change the oil in a diesel generator. First, the oil helps keep the engine clean by moving dirt and debris and taking them to the oil filter. Second, the oil keeps the engine lubricated so that parts move smoothly. Third, the oil protects the engine from corrosion. Finally, the oil helps prevent damage to the engine. So with time, the oil will break down and lose its efficiency and lubricating property, which calls for a change to avoid damage to the engine. See Some unknown facts about engine oil.

When Should the Oil Be Changed?

Every 200 to 250 hours, or every three months, you should change the oil. But some engines need to be changed more frequently than others. Observe the manufacturer's guidelines. Check the oil level and replace the oil right away if you hear any strange noises emanating from the engine, such as grinding, rattling, or clanking sounds.

What is the price?

A diesel generator's oil replacement costs $15 to $40 per 4L. You will spend more on synthetic oil than on regular engine oil. Look at What increases the fuel consumption of the generator?
