Changing Fuel Filter On Bobcat S130: Step-By-Step Guide

If you want to change the fuel filter on your Bobcat S130, you'll need to get your hands on a filter service kit. These are available to buy online and should include a spin-on oil filter, a fuel filter, a primary air filter, and a hydraulic filter. You'll also need shop towels or rags, a filter wrench, and other tools. Before performing any maintenance work, check your operation and maintenance manual and make sure the engine is cool.

Check and drain water

To check and drain water from your Bobcat S130, you should begin by checking the water separator bowl. Only drain the bowl when water is visible, when you get a 'water in fuel' error code, or when you are replacing the fuel filter.

To drain the water, first install an extra hose, then loosen the drain.

It is recommended that you service the fuel filter every 1,000 hours or annually. However, if you do not need to service the filter, simply drain the water and then reconnect the separator bowl.

Disconnect the electrical connector

To disconnect the electrical connector on your Bobcat S130, first ensure that the engine is cool. Then, locate the electrical connector – it will be attached to the fuel filter. Once you've found it, simply disconnect it by gently pulling it away from the fuel filter. Be careful not to damage the connector or any surrounding components.

It's important to note that you should only service the fuel filter when necessary; otherwise, it should be replaced every 1,000 hours or annually. Before performing any maintenance work, always check the operation and maintenance manual for your specific model.

When disconnecting the electrical connector, you may need to remove other components for easier access. Make sure to keep track of the order in which you removed them so that you can properly reassemble them later. Lay out the components in the order they were removed to make reassembly easier.

Additionally, it's a good idea to clean the area around the electrical connector before proceeding. This will help prevent any dirt or debris from entering the fuel system. Use shop towels or rags to clean the area thoroughly.

Once the electrical connector is disconnected, you can proceed with removing and replacing the fuel filter. Remember to always refer to the official maintenance guidelines for your Bobcat S130 to ensure a safe and proper procedure.

Remove the old filter

To remove the old filter from your Bobcat S130, start by checking the water separator bowl. Drain the bowl if there is water present, or if you have received a 'water in fuel' error code. You should also drain the bowl every time you replace the fuel filter. Install an extra hose and then loosen the drain.

Next, disconnect the electrical connector and remove the separator bowl. Remove the old filter and set it aside for disposal.

Now, clean the pre-filter and the surrounding area. Move the hose clamps off and then carefully remove each fuel hose, loosening the filter clamp. Before removing the pre-filter, make a note of the orientation of the arrow on it. Once you have made a note of the arrow's position, you can remove and discard the pre-filter.

Install a new filter

To install a new filter, do not pre-fill the new filter with fuel. Lubricate the new O-rings. Install the separator bowl before installing it onto the filter housing. Connect the electrical components and perform any final cleanup. The fuel system will need to be primed with fuel, and air will need to be removed from the system.

Any time a fuel filter is replaced, the pre-filter will need to be primed and air removed from the system. Your machine may also have a fuel tank vent or breather cap that vents excess pressure. Replace this with a new genuine Bobcat part.

Prime and remove air from the fuel system

To prime and remove air from the fuel system of a Bobcat S130, follow these steps:

Firstly, ensure you have the necessary items to hand: a genuine Bobcat fuel filter (part number 7336334), a genuine Bobcat pre-filter (part number 7348032), a genuine Bobcat fuel tank vent or breather cap, shop towels or rags, a 9mm (3/8 in) x 300mm (12 in)-600mm (24 in) extra hose, a filter wrench and other tools. Check the operation and maintenance manual before performing any maintenance work, and make sure the engine is cool before starting.

Now, to the priming and air removal:

First, check the water separator bowl. Only drain when water is visible, or when notified by a 'water in fuel' code, or when replacing the fuel filter. Install an extra hose and then loosen the drain.

Next, disconnect the electrical connector and remove the separator bowl. Remove the old filter. Do not pre-fill the new filter with fuel. Lubricate the new O-rings and install the separator bowl before installing the new filter onto the filter housing. Connect the electrical and perform any final cleanup.

Now, clean the pre-filter and surrounding area. Move the hose clamps off, and then remove each fuel hose and loosen the filter clamp. Note the orientation of the arrow on the pre-filter before removing and discarding it.

Finally, install the new pre-filter, ensuring the arrow is facing the correct direction. Install the hoses and move the clamps back to the correct position. Remove the hose pliers.

You have now primed and removed air from the fuel system.
