As a supplier of Trailer Mounted Pumps, ensuring the proper maintenance of these essential machines is crucial. One of the fundamental maintenance tasks is checking the oil level in a trailer-mounted pump. In this blog, I'll guide you through the process step by step, so you can keep your pump running smoothly and efficiently.
Why Checking the Oil Level is Important
Before we dive into the checking process, let's understand why it's so important to monitor the oil level in your trailer-mounted pump. Oil serves multiple vital functions in the pump's engine. It lubricates the moving parts, reducing friction and wear, which extends the engine's lifespan. It also helps to cool the engine by carrying heat away from the critical components. Additionally, oil acts as a sealant, preventing contaminants from entering the engine and causing damage.
If the oil level is too low, the engine may not receive adequate lubrication, leading to increased friction, overheating, and potentially severe engine damage. On the other hand, an overfilled oil level can cause foaming, which reduces the oil's lubricating properties and can also lead to engine problems. Therefore, regularly checking the oil level is essential to maintain the pump's performance and prevent costly repairs.
Tools You'll Need
To check the oil level in your trailer-mounted pump, you'll need a few basic tools:
- Clean Rag or Paper Towel: This is used to wipe the dipstick clean before and after checking the oil level.
- Flashlight (Optional): If the dipstick is located in a hard-to-reach or dimly lit area, a flashlight can help you see the markings on the dipstick more clearly.
Step-by-Step Guide to Checking the Oil Level
Now, let's go through the process of checking the oil level in your trailer-mounted pump:


Step 1: Park the Pump on a Level Surface
Before checking the oil level, make sure the trailer-mounted pump is parked on a level surface. This ensures that the oil is evenly distributed in the engine, giving you an accurate reading on the dipstick. If the pump is parked on an incline, the oil may pool on one side of the engine, leading to an incorrect oil level reading.
Step 2: Let the Engine Cool Down
If the pump has been running recently, allow the engine to cool down for at least 10 - 15 minutes. This is important because hot oil can be dangerous to handle, and it may also give an inaccurate reading on the dipstick due to expansion.
Step 3: Locate the Dipstick
The dipstick is a long, thin rod with a loop or handle at one end. It is usually located near the engine and is marked with "Oil" or has an oil can symbol. Refer to your pump's owner's manual if you're having trouble finding the dipstick.
Step 4: Remove the Dipstick
Once you've located the dipstick, grasp the loop or handle and pull it out slowly. Be careful not to spill any oil on the engine or surrounding area.
Step 5: Wipe the Dipstick Clean
Use a clean rag or paper towel to wipe the dipstick clean. This removes any oil residue or debris from the dipstick, ensuring an accurate reading.
Step 6: Reinsert the Dipstick
After wiping the dipstick clean, insert it fully back into the dipstick tube. Make sure it is inserted all the way to the bottom.
Step 7: Remove the Dipstick Again and Check the Oil Level
Pull the dipstick out again and look at the end. The dipstick is marked with two lines or dots: a lower line indicating the minimum oil level and an upper line indicating the maximum oil level. The oil level should be between these two marks.
- If the oil level is below the lower line: This means the oil level is too low, and you need to add oil to the engine. Refer to your pump's owner's manual for the correct type and amount of oil to use.
- If the oil level is above the upper line: This means the oil level is too high, and you may need to drain some oil from the engine. Again, refer to your pump's owner's manual for the proper procedure.
- If the oil level is between the two lines: This is the ideal oil level, and your pump is ready to operate.
Step 8: Clean the Dipstick and Reinsert It
Once you've checked the oil level, wipe the dipstick clean again and reinsert it into the dipstick tube. Make sure it is securely in place.
Additional Tips
- Check the Oil Regularly: It's a good idea to check the oil level in your trailer-mounted pump before each use or at least once a week if the pump is used frequently.
- Inspect the Oil Condition: While checking the oil level, also take a look at the oil's color and consistency. Clean oil should be amber or light brown in color and have a smooth consistency. If the oil is dark, dirty, or has a milky appearance, it may indicate a problem with the engine, such as a coolant leak or excessive wear. In this case, it's best to have the pump inspected by a professional.
- Keep a Record: Keeping a record of the oil level checks can help you identify any trends or issues with the pump's oil consumption. This can be useful for maintenance planning and troubleshooting.
