Replacing The 550 Ford Backhoe Fuel Filter: Step-By-Step Guide

Changing the fuel filter on a 550 Ford Backhoe is a straightforward process that can be done by following these steps: First, locate the primary fuel filter under the driver's side door, on the frame rail. Next, turn off the fuel supply by closing the tap on the bottom of the tank. Then, loosen the bolt that holds the fuel filter together and remove the old filter cartridge, making sure to catch any excess fuel. Install a new filter cartridge and seal, and turn the fuel supply back on. Finally, bleed the low-pressure side of the fuel system by opening the tap under the tank and loosening the bleed screw until air bubbles stop appearing. This process ensures that the fuel filter is working optimally and helps maintain the engine's performance.

Locate the fuel filter

To locate the fuel filter on a 550 Ford Backhoe, begin by locating the driver's side door. The fuel filter is situated under the driver's side door, specifically on the frame rail. It is positioned on the right side of the engine, if you are facing forward.

The fuel filter is a crucial component of the fuel system, playing a significant role in ensuring optimal fuel efficiency and engine performance. It is responsible for filtering dirt, debris, and contaminants from the fuel before it reaches the engine.

Once you have located the fuel filter, you will notice that it is part of a larger assembly. The fuel filter assembly consists of several components, including the filter body, the glass bowl at the bottom, and a bolt or threaded shaft that holds everything together.

Before proceeding with any maintenance or repair work on the fuel filter, it is essential to turn off the fuel supply by closing the tap located at the bottom of the fuel tank. This will prevent fuel leakage and ensure a safer working environment.

Additionally, it is important to note that the fuel filter is part of a larger fuel system, which includes both low-pressure and high-pressure components. The fuel filter is situated at the point where the low-pressure fuel system towards the rear of the digger meets the high-pressure fuel system towards the front.

Turn off the fuel tap

To turn off the fuel tap on your Ford 550 backhoe, locate the fuel-filter on the right-hand side of the engine. Before you begin any work on changing the fuel filter, it is important to turn the fuel supply off using the tap located at the bottom of the tank. The filter is gravity-fed from the tank, so if you don't close the fuel supply off first, the tank will drain through the filter housing when you remove the old filter.

The fuel-filter is made up of three parts: the filter body, the glass bowl at the bottom, and a bolt/threaded shaft that holds it all together. You will need to undo the bolt at the top, which is probably a 7/16" size, allowing for rust and rounded edges.

Once you have loosened the bolt, you can then turn your attention to the tap under the glass bowl. Open this tap to drain any remaining fuel from the filter. This will ensure that the fuel doesn't leak out when you remove the old filter.

By following these steps, you can safely turn off the fuel tap on your Ford 550 backhoe and proceed with changing the fuel filter.

Undo the bolt

To undo the bolt on the fuel filter of a 550 Ford Backhoe, you will need to identify the bolt that needs to be loosened. The bolt in question is located at the top of the fuel filter assembly, which is situated on the right side of the engine when facing forward. It is important to turn off the fuel supply by closing the tap on the bottom of the fuel tank before attempting any work on the fuel filter. This is because the filter is gravity-fed, and failing to do so will result in the tank draining through the filter housing.

The bolt that holds the fuel filter assembly together is approximately 11.25mm in size, or 7/16" allowing for rust and rounded edges. To undo this bolt, you will need a suitably sized wrench or socket. Before loosening the bolt, it is advisable to place a bowl or container underneath the filter assembly to catch any fuel that may leak out during the process.

Once you have the correct tool and have taken the necessary precautions, you can proceed to undo the bolt. Place the wrench or socket on the bolt and apply force in the counter-clockwise direction to loosen it. It may require significant force, especially if the bolt has not been removed in some time. It is important to be cautious and controlled during this process to avoid stripping the bolt head or damaging the surrounding components.

After the bolt is loosened, you can proceed to remove it by hand or with the wrench/socket. With the bolt removed, the fuel filter assembly can be disassembled for cleaning, replacement, or other maintenance tasks. It is recommended to wrap tissue or absorbent material around the filter to catch any excess fuel before disassembling the components.

In summary, undoing the bolt on the fuel filter of a 550 Ford Backhoe requires the correct tools, prior knowledge of fuel systems, and a cautious approach to avoid damage or injury. Always refer to a qualified mechanic or service manual for detailed instructions and safety precautions before attempting any vehicle maintenance or repairs.

Drain the fuel

To drain the fuel from your 550 Ford Backhoe, start by locating the fuel tap on the bottom of the tank. Turning this off will prevent the filter from draining fuel when it is removed.

Next, locate the fuel filter. This is on the right side of the engine, where the low-pressure fuel system meets the high-pressure fuel system. You will see the fuel injector pump just ahead of and behind the filter.

The fuel filter is made up of three parts: the filter body, the glass bowl at the bottom, and a bolt/threaded shaft that holds it all together. Undo the bolt at the top of the filter with a 7/16" spanner. Place tissues around the filter to catch any excess fuel as you loosen it.

Now, open the drain tap under the glass bowl and let the fuel drain out. You can also open the bleed screw next to the bolt that holds the filter together to allow air to escape as the fuel drains.

Once the fuel has drained, you can remove the old filter and replace it with a new one.

Replace the filter

The fuel filter is on the right side of the engine, facing forward. The filter is where the low-pressure fuel system meets the high-pressure fuel system. Before you start, turn the fuel off with the tap on the bottom of the tank. The filter is gravity-fed, so the tank will drain through the filter housing if you forget this step.

The fuel filter is made up of three parts: the filter body, the glass bowl at the bottom, and a bolt/threaded shaft that holds it all together. Undo the bolt at the top of the filter with a 7/16" spanner. Place tissues around the filter to catch any excess fuel as you loosen it.

Once the filter is loose, you can start to strip it down into its component parts. You will need to replace the filter cartridge, and the two seals that go between the cartridge and the housing, and the cartridge and the glass bowl. One seal is slightly bigger than the other—the larger one goes at the top, and the smaller one at the bottom.

The new filter cartridge will come with two new seals and two o-rings. One o-ring goes where the fuel feeds into the filter assembly. The other, smaller o-ring doesn't have an obvious place—its purpose is unclear. With the filter screwed back together, turn the fuel back on and bleed the low-pressure side of the fuel system. Open the tap under the tank, and the filter will start filling with fuel. The filter bleed-screw is next to the bolt that holds the filter together. Use a 15mm spanner to loosen it until air starts bubbling out.

Bleeding the fuel filter relies on the tanks being full enough to force fuel and air out of the bleed-screw. If the fuel stops running without clear fuel starting to come out of the bleed-screw, your fuel tap may be blocked. Once fuel without air bubbles is running from the bleed-screw, tighten it and you're done.
