Replacing Fuel Lines In Troybuilt Chainsaws: A Step-By-Step Guide

Chainsaw fuel lines can clog, crimp, or crack over time, causing the engine to stop working. To replace the fuel line 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 first step is to empty the fuel tank into an approved storage container. Next, remove the cylinder shield, disconnect the spark plug wire, and take out the air filter. Then, remove the fuel filter and the carburetor. Pull the fuel lines off the carburetor and primer bulb, and out of the gas tank, using needle-nose pliers. Finally, install the new fuel lines, cut them at an angle, and push them into the tank.

Remove the cylinder shield

To remove the cylinder shield from your chainsaw, you will need an Allen wrench. This is the only tool required for this step.

First, use the Allen wrench to remove the screws that hold the cylinder shield in place. Once the screws have been removed, simply lift the shield off. It is important to keep track of the screws so that you can reinstall the shield later.

This step is part of a larger process of replacing the fuel lines in your chainsaw. Before beginning, ensure you are wearing protective gloves and are working in a well-ventilated area.

Disconnect the spark plug wire and remove the air filter

Disconnecting the spark plug wire and removing the air filter is an important step in maintaining your chainsaw. Here's a detailed guide on how to do it:

Disconnect the Spark Plug Wire:

• Locate the spark plug wire. It is usually connected to the spark plug, which is often located near the engine.
• Carefully disconnect the wire from the spark plug. This step is crucial for safety as it helps prevent accidental starting of the engine during maintenance.

Remove the Air Filter:

• Identify the air filter housing, which is typically located near the engine.
• Pull off the cover of the air filter housing. It may require some force to remove, but be gentle to avoid damaging any components.
• Once the cover is removed, carefully take out the air filter. It is essential to handle the air filter with care as it can be delicate.

By following these steps, you will have successfully disconnected the spark plug wire and removed the air filter from your Troybilt chainsaw. Remember to refer to your chainsaw's user manual for any model-specific instructions or variations. Always exercise caution when performing maintenance on power tools, and ensure you are wearing appropriate safety gear, including gloves and eye protection.

Additionally, it is worth noting that regular maintenance and cleaning of your chainsaw's air filter are essential to ensure optimal performance. Cleaning the air filter after each cutting session is ideal, and it should be replaced if there are any tears or holes in the mesh.

Remove the fuel filter

To remove the fuel filter from your Troybilt chainsaw, you will need to straighten a piece of coat hanger and bend a hook on one end. Feed the straightened coat hanger through the mouth of the fuel tank and fish out the white cylindrical fuel filter. Once you have located the fuel filter, use a pair of scissors or something similar to cut the fuel line and remove the filter.

Remove the carburetor

To remove the carburetor from your Troybilt chainsaw, you will need a 7/16-inch socket driver. Before you begin, ensure you are wearing work gloves to protect your hands.

First, in a well-ventilated area, remove the fuel cap and empty the fuel tank into an approved storage container. Next, disconnect the spark plug wire and remove the air filter. Pull the cover off the air filter housing and remove the filter.

Now, you can remove the carburetor. Using your 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, and then pull the carburetor from the engine block, sliding it along the mounting studs. Be careful not to bend the throttle linkage or damage the gas lines.

Remove and install the new fuel lines

To remove the old fuel lines, use a pair of needle-nose pliers to pull the fuel lines off the carburetor and primer bulb. 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 lines at an angle with a pair of 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 the needle-nose pliers. Pull the small line out of the mouth of the tank, cut the end square, and install the fuel filter. Pull the line back into the tank so that the filter rests on the bottom. Trim the fuel lines and connect them to the carburetor. Lubricating the fuel lines with a drop of oil can help ease threading.
