How to Change Transmission Oil Pump?

In construction machinery, the transmission oil pump plays a vital role in delivering lubricant to the drive train to ensure the smooth operation of the equipment. The following will detail how to replace transmission oil pump in construction machinery to maintain the performance and reliability of the equipment.

Step 1: Preparation

Before replacing the transmission oil pump, make sure that the construction machinery has been shut down, the power supply has been cut off, and the transmission system is in a cool state to prevent it from affecting the normal operation of other diesel engine parts afterwards. Meanwhile, prepare the following tools and materials:

A new transmission oil pump suitable for the machine model

Wrenches and wrenching gloves

Oil drum or other container

Rags or paper towels

Step 2: Locate the old oil pump

Where is the transmission oil pump located? Typically, the transmission oil pump is located in the drivetrain of construction machinery, and the transmission oil pump location varies depending on the model and manufacturer of the machine. Use a wrench or wrenching glove to carefully remove the connection bolts of the old transmission oil pump.

Step 3: Drain the old oil

Once the transmission oil pump attachment bolts have been removed, you will be able to access the transmission oil pump's oil line. 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 Transmission Oil Pump

Carefully install the new transmission oil pump into the driveline, making sure it is properly aligned with the attachment bolts. Tighten the tie bolts to ensure the diesel oil pump is securely in place.

Step 5: Add new lubricant

Prepare a new lubricant for your machine. Using the transfer funnel, pour the new oil into the oil line of the diesel oil pump until it fills up and begins to overflow. Make sure you use the proper type and size of lubricant for your machine.

Step 6: Test the Equipment

Finally, start the construction machine and let it run for a few minutes to ensure that the new transmission oil is adequately distributed into the drive train. Check for any leaks or unusual noises to ensure that the equipment is running properly and to avoid interfering with the proper functioning of other parts of the machine such as the starter motor or alternator.

Changing the transmission oil pump on your construction equipment is a critical step in maintaining the performance and reliability of your equipment. Following these steps and replacing the oil pump on a regular basis will help to ensure that your construction equipment remains efficient and reliable in its work tasks. Don't overlook this critical maintenance step to ensure that your equipment provides optimal performance when needed.
