If you need to change the fuel pump on your International 444 tractor, you can either buy a new one or repair the old one. There are repair kits available for purchase online, and you can also find tutorials online that explain how to remove and reinstall the fuel pump. The process involves cleaning the pump and the surrounding area, scribing lines on the pump and mounting gear for reference during reinstallation, removing the front cover of the pump drive gear cover, disconnecting fuel and injector lines, loosening and removing screws and nuts, and then carefully wiggling and pulling the pump out.

Clean the pump and surrounding area

To clean the pump and surrounding area of your International 444 tractor, begin by parking the tractor on a level surface and engaging the parking brake. Gather your cleaning supplies, including rags, brushes, and an air gun. Start by wiping down the exterior of the pump and the surrounding area with a clean rag to remove any dirt, dust, or debris. Use a small brush to reach any tight spaces or crevices. Be careful not to damage any sensitive components or wiring.

Once you've removed the visible dirt, use the air gun to blow away any remaining dust or debris from the pump and the surrounding area. Pay close attention to the crevices and hard-to-reach areas, as dirt and debris can accumulate in these places. After blowing away the loose particles, use a clean, dry cloth to wipe down the area once more, ensuring that all dirt and dust have been removed.

If there are any fuel leaks or spills, use an appropriate absorbent material, such as rags or paper towels, to soak up the fuel. Be sure to dispose of the absorbent material properly and safely. Do not use open flames or sparks near the tractor during the cleaning process, as fuel vapours can be highly flammable.

Finally, inspect the pump and the surrounding area for any signs of damage or wear. Look for cracks, leaks, or loose connections. If you notice any issues, address them before proceeding with the fuel pump replacement. It is important to ensure that the area is clean and free of debris to reduce the risk of contamination and ensure a successful repair.

Scribe a line between the pump and mounting on the pump drive gear housing

Scribing a line between the pump and mounting on the pump drive gear housing is an important step when changing the fuel pump on an International 444 tractor. This process helps ensure that the pump is correctly aligned during reinstallation.

To begin, make sure the pump and the area around it are clean. Use an air gun to blow away any remaining debris. This step is crucial as it ensures that no dirt or grime will interfere with the pump's function or cause damage during the removal and reinstallation process.

Next, you will need a scribing tool. A scribe is a hand tool used to mark or engrave lines on hard materials, like metal. Position the scribe between the pump and the mounting on the pump drive gear housing. Firmly drag the scribe along the surface, creating a visible line. This line will serve as a reference point for reinstalling the pump.

Make sure the scribe line is straight and clearly visible. Once you are satisfied with the scribe line, you can proceed to the next steps of removing the fuel pump. This may include removing covers, disconnecting lines, and loosening screws and bolts.

When it's time to reinstall the fuel pump, carefully align the scribe marks. This will ensure that the pump is positioned correctly in relation to the pump drive gear housing. Failure to align the scribe marks accurately may result in improper pump installation and potential issues with the tractor's performance.

Remember to take your time and work carefully. Changing the fuel pump on an International 444 tractor can be a complex task, but by following the correct procedures and paying attention to details like scribe lines, you can help ensure a successful outcome.

Remove the front cover of the pump drive gear cover

To remove the front cover of the pump drive gear cover on your International 444 tractor's fuel pump, follow these steps:

Begin by cleaning the pump and the surrounding area. Use an air gun to blow away any debris or dirt. Next, using a scribe, carefully mark a line between the pump and the mounting on the pump drive gear housing. This scribe line will be an important reference point during the re-installation process, so it is important to be precise.

Now, you are ready to remove the front cover. First, scribe a line on the timing gear and the pump drive gear. This line will also aid in the re-installation process, ensuring that the pump is correctly aligned. Once the scribe marks are in place, disconnect all the fuel and injector lines from the pump. Cover the lines and port ends to prevent any dirt contamination, which could cause issues with the tractor's performance.

With the fuel and injector lines disconnected and safely covered, it is now safe to proceed with removing the front cover. Loosen, but do not completely remove, the three screws in the pump drive gear. You can now access and remove the three nuts from the pump mounting bolts. After removing these nuts, you can then completely remove the three screws from the pump drive gear.

At this point, you should be able to remove the pump. Grab the pump and gently wiggle it towards the rear of the tractor. Pull it out carefully, being cautious not to drop the dowel pin into the timing gear housing. There is a paper gasket between the pump and the timing gear cover that should be replaced during re-installation.

Remember to carefully follow the reverse procedure for re-installation, ensuring that all scribe marks are correctly aligned.

Disconnect all fuel and injector lines from the pump

To disconnect the fuel and injector lines from the pump of your International 444 tractor, follow these steps:

Begin by cleaning the pump and the surrounding area. Use an air gun to blow away any debris or dirt that may have accumulated. This step is important to prevent any contamination of the fuel and injector lines during the disconnection process. Once the area is clean, use a scribe to mark a line between the pump and the mounting on the pump drive gear housing. This will help you realign the pump correctly during reassembly.

Next, remove the front cover of the pump drive gear. Again, use the scribe to mark a line on the timing gear and the pump drive gear. These marks will be crucial for ensuring proper timing during reinstallation. Now, you can start disconnecting the fuel and injector lines. First, locate all the lines connected to the pump. There should be multiple lines, including fuel lines and injector lines. Disconnect each line carefully, one at a time. It is important to cover the lines and port ends with appropriate coverings to prevent dirt contamination while the system is open.

Work slowly and deliberately to avoid any spills or leaks. Make sure to have rags or absorbent materials on hand to wipe up any fuel that may spill during the disconnection process. Once all the lines are disconnected, set them aside, ensuring they remain covered to avoid contamination. It is also a good idea to tag or label the lines to make reassembly easier. By following these steps, you will have successfully disconnected all the fuel and injector lines from the pump of your International 444 tractor. Remember to take your time and work carefully to avoid any potential issues.

Loosen and remove the pump mounting bolts and screws

To loosen and remove the pump mounting bolts and screws, you will need to follow a few careful steps. Firstly, clean the pump and the surrounding area. Use an air gun to blow away any debris or dirt. Next, use a scribe to mark a line between the pump and the mounting on the pump drive gear housing. This will help you realign the pump correctly when you reinstall it. Remove the front cover of the pump drive gear cover. You will then need to scribe another line, this time on the timing gear and pump drive gear. This line will also guide you during the reinstallation process.

Now you are ready to disconnect all the fuel and injector lines from the pump. Cover the lines and port ends to prevent any dirt contamination. At this stage, you can loosen the pump drive gear screws. There should be three screws. Once these are loose, you can remove the nuts from the pump mounting bolts. Again, there are three nuts to remove. After removing these, you can then take out the three screws from the pump drive gear. Now, carefully grab the pump and wiggle it towards the rear of the tractor. It should come out of the drive gear. Be cautious not to drop the dowel pin into the timing gear housing.

When removing the pump, be mindful of a paper gasket on the pump and the timing gear cover. This gasket should be replaced during reinstallation. The process of removing the pump mounting bolts and screws is now complete, and you can continue with the rest of the fuel pump replacement procedure.
