Replacing Fuel Sender On John Deere X500: Step-By-Step Guide

If the fuel gauge on your John Deere X500 has stopped working, the problem may be with the fuel gauge sending unit. To fix this, you will need to remove the fender deck to access the fuel sender. Once you have removed the sending unit from the tank, you can use an ohm meter to check the resistance between the terminals by connecting it to the black and black/white wires and moving the float up and down. If the reading is not between 6-200 ohms, you will need to replace the sender. You can also check if the gauge moves by removing the sender, turning the key on, and moving the float up and down.

Remove the fender deck to access the fuel sender

To remove the fender deck and access the fuel sender, you will need to follow these steps:

Begin by locating and removing the bolts that secure the rear end of the tractor. This will allow you to access the components underneath the fender deck.

Next, remove the two springs that support the seat. This will give you more room to work and access the necessary areas.

After that, take out the battery and the battery tray. Be sure to disconnect the battery cables and set the battery aside in a safe place.

Now, you will need to remove the bolts holding the black cowling and the front of the green platform to the frame. This will allow you to lift the seat platform and provide access to the fuel sender.

Finally, carefully lift and remove the fender deck. Set it aside and you will now have access to the fuel sender for replacement or repair.

Remember to work safely and ensure that the tractor is turned off and disconnected from any power sources before beginning any maintenance or repair work.

Disconnect the fuel sender from the tank

To disconnect the fuel sender from the tank, you will need to first access the fuel sender by removing the fender deck.

Once you have located the fuel sender, you will need to disconnect the electrical connector and any fuel lines that are attached to it. Make sure you have a container to catch any fuel that may spill during this process.

Next, you will need to remove the mounting hardware that secures the fuel sender to the tank. This will vary depending on your model, but it will typically involve removing several bolts or screws. With the mounting hardware removed, you should now be able to carefully lift the fuel sender out of the tank.

If your fuel sender is integrated with the fuel pump, as is the case with some John Deere models, you will need to take extra care to avoid spilling fuel. You may also need to remove additional components, such as the rear fenders or the battery, to access the fuel tank and sender unit.

It is important to consult your owner's manual or a trusted mechanic if you are unsure about any steps in this process. Working on fuel systems can be dangerous if not done properly, so always take the necessary precautions and work in a well-ventilated area.

Check the resistance between terminals with an ohm meter

To check the resistance between terminals with an ohm meter, you must first remove the fender deck to access the fuel sender. Once you have done that, you need to remove the sending unit from the tank. Then, with an ohm meter, check the resistance between terminals by connecting it to the black and black/white wires. Move the float up and down to see the resistance between terminals. The readings should be between 6-200 ohms. If the reading is not within this range, replace the sender.

Additionally, with the sender removed, move the float up and down with the key on to see if the gauge moves. If the gauge moves, this indicates that the sender is functioning correctly. If the gauge does not move, then the sender may need to be replaced.

It is important to note that the fuel gauge on a John Deere tractor has a unique resistance range of 6-200 ohms, which is different from the standard ranges used in most industries. Therefore, you may need to purchase a meter bridge to match the sending unit to the gauge.

Observe the gauge movement with the float up/down and key on

To observe the gauge movement with the float up/down and key on, you must first remove the fender deck to access the fuel sender. Once you have access, remove the sending unit from the tank. With an ohmmeter connected to the black and black/white wires, observe the resistance between terminals when moving the float up and down. The readings should be between 6-200 ohms. If the reading is outside of this range, replace the sender. With the sender removed, key on, and move the float up and down. Observe if the gauge moves.

Replace the fuel sender if the readings are outside the range of 6-200 ohms

To replace the fuel sender on a John Deere X500, you will first need to remove the fender deck to access the fuel sender. Once you have located the fuel sender, you will need to disconnect the wiring harness and remove the sending unit from the fuel tank. Be sure to properly dispose of any old fuel.

You will then need to purchase a replacement fuel sender. Ensure that the replacement part is compatible with your specific John Deere model. When installing the new fuel sender, follow the manufacturer's instructions and refer to the John Deere X500 service manual if necessary.

Finally, reconnect the wiring harness to the new fuel sender and secure it in place. Start the engine and check the fuel gauge to ensure it is functioning correctly.

If you are experiencing issues with your fuel gauge, it is recommended to first test the fuel sender to determine if it is functioning correctly. To do this, connect an ohmmeter to the black and black/white wires of the fuel sender. Move the float up and down manually while observing the ohmmeter readings. If the readings are outside the range of 6-200 ohms, replace the fuel sender.
