How to Change Oil Pump?

Maintaining construction machinery is a critical part of ensuring the performance and longevity of the equipment, and replacing the oil pump is one of those important maintenance tasks. Oil pumps play a key role in machinery by lubricating the engine, reducing wear and tear, and maintaining proper operation. Below we will detail how to replace the oil pump in your construction machinery to ensure the reliability and efficiency of your equipment.

Step 1: Preparation

Before you start to replace the oil pump, make sure the construction machinery has been completely shut down and the power supply has been cut off to avoid affecting other diesel engine parts. in addition, wait for a period of time to make sure the lubricating oil in the machine cools down to ensure the safety of operation. Meanwhile, prepare the following tools and materials:

A new oil pump suitable for your model of construction machinery.

Wrenches and wrenching gloves.

Oil drum or other container to store the old lubricant.

Rags or paper towels to clean your tools and work area.

Step 2: Locate the old oil pump

The diesel oil pump is usually located in the engine section of construction machinery, but the exact location will vary depending on the model and manufacturer of the machine. Carefully remove the old oil pump's attachment bolts using a wrench or wrenching glove and remove the old pump.

Step 3: Drain the old oil

Once the oil pump attachment bolts have been removed, you will be able to access the outlet pipe of the old oil pump. Using a suitable container, drain the old oil. Make sure to drain all of the old oil to ensure the purity of the new lubricant.

Step 4: Install the New Oil Pump

Carefully install the new oil pump into the engine of the construction machine, making sure it is properly aligned with the attachment bolts. Tighten the attachment bolts to ensure that the pump is securely in place. Also, make sure that the sealing part of the oil pump is installed correctly to prevent problems with future leaks.

Step 5: Add new lubricant

Prepare new lubricating oil suitable for construction machinery. Using a transfer funnel, pour the new lubricant into the inlet pipe of the oil pump until it fills up and begins to overflow. Make sure you use the correct type and specification of lubricant for the model of machine to meet the needs of the equipment and for the proper operation of other accessories such as the starter motor and alternator.

Step 6: Test the equipment

Finally, start the machine and let it run for a few minutes to ensure that the new lubricant is well distributed throughout the lubrication system. Double-check for any leaks or unusual noises to make sure the equipment is running properly.

Maintaining the oil pump of your construction machinery is a critical step in ensuring the long-term performance and reliability of your equipment. Regular oil pump changes will help ensure that your equipment remains efficient and reliable during work tasks. Don't underestimate the importance of this critical maintenance task to ensure your equipment delivers optimal performance when needed. By maintaining and replacing your oil pump, you can increase the life of your equipment, reduce repair costs and ensure the continued efficient operation of your construction machinery.
