Troybilt Chainsaw Fuel Line: Easy Replacement Guide

Chainsaw fuel lines can clog, crimp or crack over time, causing the engine to stop working. To replace the fuel lines in a Troybilt chainsaw, you will need a 7/16-inch socket driver, an approved fuel container, paper towels or shop rags, work gloves, and an Allen wrench. The process involves removing the fuel cap, emptying the fuel tank, taking off the cylinder shield, disconnecting the spark plug wire, removing the air filter, detaching the fuel filter, unscrewing the carburetor, pulling out the old fuel lines, and installing the new fuel lines. It is important to wear safety gear and follow the instructions in the repair guide to ensure a successful and safe replacement.

Remove the cylinder shield

To remove the cylinder shield from your chainsaw, you will need an Allen wrench. This tool will allow you to remove the screws that hold the cylinder shield in place, attached to the engine. Once the screws have been removed, simply lift off the shield.

It is important to note that this process should be done in a well-ventilated area, and you should wear work gloves to protect your hands. Additionally, before beginning any chainsaw maintenance, ensure that you have the proper tools and safety equipment. Consult your operator's manual for detailed instructions and safety precautions specific to your chainsaw model.

Disconnect the spark plug wire and remove the air filter

Disconnecting the spark plug wire and removing the air filter are crucial steps in replacing the fuel line of your chainsaw. Here is a detailed, step-by-step guide to help you with the process:

Disconnecting the Spark Plug Wire:

• Start by locating the spark plug wire. It is usually found on the side or top of the chainsaw's engine.
• Using a pair of pliers, grip the boot of the spark plug wire and gently twist it counterclockwise.
• Once it is loose, carefully pull the boot off the spark plug to disconnect the wire.

Removing the Air Filter:

• Before removing the air filter, ensure that the air throttle closure is engaged to prevent dirt from entering the intake passage.
• Remove the cover from the air filter housing.
• Take out the air filter. It is typically located underneath the cover.

By following these steps, you will be able to safely disconnect the spark plug wire and remove the air filter on your Troybilt chainsaw. It is important to note that these steps may vary slightly depending on the model of your chainsaw, so it is always a good idea to refer to the manufacturer's instructions or seek professional guidance if needed.

Remove the fuel filter

To remove the fuel filter from your chainsaw, you will need to first empty the fuel tank into an approved storage container. Then, using an Allen wrench, remove the screws that hold the cylinder shield to the engine and lift off the shield. Next, disconnect the spark plug wire and remove the air filter. You can do this by pulling off the cover of the air filter housing and removing the filter.

Now, you can remove the fuel filter. Take a piece of coat hanger and straighten it, bending a hook at one end. Feed this through the mouth of the tank and use it to fish out the white cylindrical fuel filter. Cut the fuel line to remove the filter.

Once the fuel filter is removed, you can continue with the next steps to replace the fuel lines.

Remove the carburetor

To remove the carburetor from your chainsaw, follow these steps:

First, make sure you are wearing safety gloves to protect your hands. Locate the carburetor by finding the engine, as the carburetor will be attached to the intake manifold near the top of the engine. Using a 7/16-inch socket driver, remove the two mounting nuts that secure the carburetor to the engine. Pull the air filter housing off the carburetor. Be careful not to bend the throttle linkage or damage the gas lines.

Next, pull the carburetor from the engine block, sliding it along the mounting studs. Take digital photos of the throttle linkage on the carburetor and the gas line connections to ensure accurate reassembly.

If you plan to clean the carburetor, you can do so without removing it from the engine. Simply spray carburetor cleaner into all of the ports and openings, taking care to avoid the engine and any rubber parts surrounding the carburetor. Allow the cleaner to soak for at least 10 minutes, then use a toothbrush or small brush to scrub away any dirt or debris. Rinse off the cleaned parts with clean water and allow them to dry completely before reassembling.

Remove and install the new fuel lines

To remove the old fuel lines, pull the fuel lines off the carburettor and primer bulb, using needle-nose pliers. You may need to remove the screws from the primer bulb to detach the fuel lines. Next, use the needle-nose pliers to pull the fuel lines out of the gas tank.

To install the new fuel lines, cut the ends at an angle with scissors to help thread them into the tank. Push the large line about 1 inch into the tank. Push the small line into the tank and grab it with needle-nose pliers through the mouth of the tank. Pull the small line out and cut the end square. Install the fuel filter and pull the line back in so the filter rests on the bottom of the tank. Trim the fuel lines and connect them to the carburettor.
