Changing Fuel Filter On John Deere 855D Gator: Step-By-Step Guide

If you're looking to change the fuel filter on your John Deere 855D Gator, you've come to the right place. This is a guide to help you through the process, from start to finish. It's important to note that you may need specific tools for this task, such as a filter wrench, and you should always refer to the operator's manual for detailed instructions. Additionally, some people have reported difficulties accessing the fuel filter, so you may need to get creative with your approach. Now, let's get started on changing that fuel filter!

Bleeding the fuel lines

To bleed the fuel lines of your John Deere 855D gator, you need to prime the system until fuel is returning to the tank.

Firstly, check your fuel filter housing for any hairline cracks in the plastic bowl and check to make sure everything is tight. Then, trace your fuel lines back to the tank and make sure none are rubbed through or leaking.

If you are still having issues, there are a few other methods you can try. One is to put a little bit of air pressure in the fuel tank, which will cause fuel to spill out of wherever the air is getting into the system. You only need to put enough air in to make it leak. You can do this by wrapping a blow gun in a rag and sticking it in the fuel fill, then pumping in some air.

Another method is to remove the metal guard from underneath, then remove the cover to access the tank pickup/return fittings. You can then remove the clamps and rubber hoses, unscrew the retaining ring to pull the assembly from the tank, and wipe off any debris from the screen. Finally, blow compressed air into the fittings (in reverse flow) to remove any sediment, then reassemble.

If you have changed the fuel filter, put the new filter in place, and turn the key on to start your engine. You should hear the pump working after a few seconds. If the filter is not full, turn the key to start and it should now be primed and ready.

Priming the fuel system

To prime the fuel system of your John Deere 855D Gator, you will need to follow these steps:

Firstly, locate the fuel filter and ensure that it is securely in place. This is important as you will be turning on the engine and need to avoid any leaks. Once you have confirmed that the new filter is correctly installed, you can proceed to the next step.

Now, turn the key to start the engine. Listen carefully, and you should hear the fuel pump working. It may take a few seconds, but the filter should begin to fill with fuel. If the filter does not fill, turn the key to start the engine again.

Keep repeating this process until the filter is full and the system is primed. You will know the filter is full when you can hear the fuel returning to the tank. This indicates that the air has been removed from the fuel lines, and the system is now primed.

It is important to note that some John Deere Gator models may have a manual lever for priming the fuel system. This lever is usually located on the fuel pump. However, for the 855D model, it appears that the process is self-priming and does not require a manual lever.

Additionally, if you are having trouble priming the fuel system, it is recommended to refer to the Operator's Manual for specific instructions on bleeding the fuel system. This manual will provide detailed steps for your specific model and is a valuable resource for maintenance and troubleshooting.

Locating the fuel pump

To locate the fuel pump on your John Deere 855D Gator, you'll need to identify the specific model of the fuel pump currently installed in your vehicle. This is because there are different types of fuel pumps used across various John Deere Gator models, and they can be located in different areas.

One common type of fuel pump found in John Deere Gators is the in-tank fuel pump, which is located inside the fuel tank. To access this type of fuel pump, you'll need to remove the fuel tank from the Gator and then detach the fuel pump from the tank. This process can vary depending on the model of your Gator and the specific fuel pump installed.

Another type of fuel pump found in some John Deere Gators is the external fuel pump, which is typically located near the engine or the fuel tank. This type of fuel pump is usually bolted onto the vehicle's frame or mounted directly to the engine. To access it, you may need to remove any covers or panels that obstruct your access to the pump.

For the John Deere 855D Gator specifically, some models may have the fuel pump located near the fuel filter, which is positioned on the right side of the vehicle, close to the rear. However, this can vary depending on the year of manufacture and the specific model of your Gator.

If you're having trouble locating the fuel pump or determining the exact model of your John Deere 855D Gator, you can refer to the operator's manual or seek assistance from a John Deere dealer or a qualified mechanic. They will have the knowledge and resources to help you identify the fuel pump's location and provide guidance on any maintenance or repair procedures.

Additionally, when working on the fuel system, it is essential to exercise caution and refer to the manufacturer's guidelines to ensure your safety and the proper functioning of the vehicle.

Removing the fuel pump

To remove the fuel pump on a John Deere 855D Gator, you'll need to locate the fuel pump and identify the hose and clip assembly. Here is a step-by-step guide:

• Locate the Fuel Pump: The fuel pump on the John Deere 855D Gator is located near the fuel filter and the engine. It is usually attached to the fuel lines and is part of the fuel delivery system. Familiarize yourself with the location of the fuel pump and the surrounding components before proceeding.
• Prepare the Work Area: Before beginning any work, ensure the engine is off and the keys are removed to prevent any accidental startups. Place the vehicle on a flat, level surface, engage the parking brake, and chock the wheels for safety. It is also recommended to wear protective gear, such as gloves and eye protection, and have a suitable workspace with adequate lighting.
• Disconnect the Fuel Lines: Identify the fuel lines connected to the fuel pump. Carefully disconnect the lines by releasing the hose clamps or quick-release couplings. Make sure to have a drip pan or rag underneath to catch any spilled fuel.
• Release the Fuel Pump Clip: The fuel pump is typically secured by a clip or bracket. Locate this clip and carefully release it using the appropriate tool. In some cases, you may need to bend or remove the clip to access the fuel pump. Be careful not to damage the surrounding components or fuel lines.
• Remove the Fuel Pump: Once the clip is released, carefully slide out the fuel pump. You may need to wiggle it gently or use a flat-head screwdriver to loosen it if it is stuck. Be cautious not to damage the O-rings or seals during removal. Inspect the fuel pump for any signs of damage or wear and replace it if necessary.
• Clean the Area: Before installing a new fuel pump or reinstalling the old one, clean the area around the fuel lines and pump mounting point. Ensure there is no dirt, debris, or residue that could contaminate the fuel system.
• Reinstallation (if applicable): If you are reinstalling the fuel pump or installing a new one, follow the above steps in reverse. Ensure all connections are secure and that the fuel lines are properly seated and clamped.

Remember to consult the operator's manual for specific instructions related to your John Deere 855D Gator model, as there may be slight variations between different model years. Always exercise caution when working with fuel systems to avoid spills and injuries.

Replacing the fuel filter

To replace the fuel filter on a John Deere 855D Gator, you will need to purchase a new fuel filter and have some basic tools on hand. This process can be done at home, but it is important to follow the correct steps to ensure a safe and successful replacement.

Firstly, locate the fuel filter. It is usually found near the fuel pump or fuel lines. Before beginning any work, make sure the engine is turned off and allow it to cool down if it has been running recently. Once the engine is off, relieve the pressure in the fuel system by pressing the primer bulb several times.

Now, you can proceed to disconnect the fuel lines from the filter. Be prepared to catch any remaining fuel in the lines with a small container or rag.
