What You'll Learn
Remove wire and boot from spark plug
To remove the wire and boot from the spark plug of a Husqvarna 128CD, you will first need to access the spark plug. To do this, simply take off the cover. Once the cover has been removed, you can then pull the cap and wire off the spark plug.
Before proceeding, ensure that the top of the contact is free from corrosion. If there is corrosion, clean it with a wire brush. It is also important to clean the area so that it is free from dirt and debris.
Now, you can begin to remove the spark plug itself. To do this, use a combi spanner with a large opening and turn it anticlockwise. Check the spark plug for any signs of damage, such as cracks or carbon deposits. If there are carbon deposits on the electrode, clean them with a wire brush.
If the spark plug is damaged, it will need to be replaced with a new spark plug of the same type. Ensure that you use the right type of spark plug, depending on your lawn mower engine model. Using an incorrect spark plug can damage the product.

Use a T-25 Torx bit to unscrew the muffler cover
To remove the fuel tank from your Husqvarna 128CD, you will need to access the tank by removing the muffler cover. This is done by using a T-25 Torx bit to unscrew the cover. The T-25 Torx bit is a type of screwdriver with a star-shaped head designed to fit securely into the head of the screw. This will allow you to apply enough torque to unscrew the cover without slipping or damaging the screw head.
Before you begin, ensure you have the correct tool and that it is the right size. The T-25 Torx bit should fit snugly into the head of the screw. You may want to test this on one of the screws before attempting to remove them all. Place the Torx bit into the screw head and apply gentle pressure to ensure it is secure.
Once you are satisfied that you have the correct tool, begin by placing the T-25 Torx bit securely into the head of the first screw. Apply gentle pressure and turn the screwdriver counter-clockwise to loosen the screw. Repeat this process for all the screws securing the muffler cover. It is important to take your time and ensure the screwdriver is securely fitted to avoid slipping and potentially damaging the screw head.
After removing all the screws, carefully lift and detach the muffler cover. You may need to gently pry it loose if it is stuck, but be careful not to apply too much force as you don't want to damage the cover or any surrounding components. With the muffler cover removed, you will now have access to the fuel tank and can proceed with the next steps of the fuel tank removal process.

Remove screws to release muffler shield
To remove the screws to release the muffler shield of your Husqvarna 128CD, follow these steps:
Begin by removing the wire and boot from the spark plug to prevent the engine from accidentally turning on during the process. This is an important safety precaution.
Next, use a T-25 Torx bit to unthread the screws securing the muffler cover. Once the screws are removed, carefully detach the cover.
Now, you will need to remove the screws that are holding the muffler shield in place. Using your T-25 Torx bit again, unthread these screws. The muffler shield should now be released.
From here, you can proceed to detach the fuel tank from the starter housing, being mindful of the orientation of the fuel lines, as per the instructions in the video guide for fuel tank replacement.
Remember to exercise caution when performing any repairs or maintenance on your Husqvarna 128CD, and ensure you are working in a well-ventilated area when working with fuel or oil.

Unscrew starter housing
To unscrew the starter housing of a Husqvarna 128CD, you will need to access the starter rope assembly. The starter rope assembly is located at the rear of the engine housing.
Firstly, ensure that the rope starter assembly is flush with the rear engine housing. Then, using a T-25 star-head screwdriver or a T-25 star-head socket and ratchet wrench, unscrew the rope starter assembly retaining screws. Once the screws have been removed, carefully lift and pull the rope starter assembly away from the rear engine housing.
Place the rope starter assembly on a flat working surface with the rope starter pulley facing upwards. Put on a pair of safety glasses to protect your eyes from any debris. Using the same type of screwdriver or wrench, unscrew the pulley retaining screw.
Now, you can lift the pulley slightly from the rope starter assembly. This will allow the pulley return spring to unwind, relieving the spring tension. Completely lift and remove the rope starter pulley from the assembly.
At this point, you will have successfully unscrewed and removed the starter housing. You can now proceed with inspecting or replacing any internal components, such as the pulley return spring or the starter rope.
