Tutorial for replacing the fuel cap key cylinder

[digital]

The first thing is to remove the two screws to remove the red plastic. Be very careful when removing the plastic, so as not to lose the 4 springs underneath.


Once the red plastic is removed, we will see that there is another spring inside with the closing anchor.


Here we can see the breakdown of the material.


Now with the help of a very fine screwdriver, we extract the rubber that covers the cylinder of the key.


We extract the rubber from the inside of the key cylinder and below there are two metal washers that must also be removed.




Now we place the key in the open position.


Once the rubber washer and the two metal washers have been removed, we will see a notch that protrudes in the cylinder, with the help of a very fine screwdriver, we can verify that if we insert the screwdriver, the notch is hidden, but due to the force exerted by its spring. It is best to use two screwdrivers, one to insert the notch inside and the other screwdriver to keep it inside. Once you hold the notch, with your thumb or forefinger, push the key cylinder outward and the key cylinder will pop out.

In the next photo you can see the protruding notch indicated by the red arrow.

Now we will proceed to insert the new fuel cap key cylinder.

We put a small amount of grease around the cylinder of the key.


Re-insert the upper rubber of the cylinder.


Insert the key into the cylinder and place the assembly as seen in the photo and in that position.
Using a very fine screwdriver, such as the one used for extraction, insert it into the notch and hold it, and at the same time, push the cylinder inwards.

We introduce the two metal washers and their rubber washer.




We place the metal sheet that you see in the photo.


We mount the spring inside its metal clasp and inside the red plastic.




Now we place the four springs and the metallic coating that will hold the four springs.
Here we must pay close attention, because as seen in the photo, the metal plate that holds the four springs, has a notch that must match as indicated by the jojo colored arrows that I have marked in the photo.


Here the work has ended being a total success.

Brilliant! Thank you

I hope you can do it with total success, it may seem somewhat complicated. Trust me, it's not complicated at all.

I have not remembered to say in the titurial that before putting grease on the cylinder, the cylinder and also its housing should be cleaned well.

I shall make this one of my first jobs over the weekend

Perfect, you will say how that process has gone.

[RedMerle]

Indeed I will 👍

Here's the project:

New (to me) blue SE has now arrived and now it's time to swap the mods on the red A4 over to the SE, which includes a black painted fuel filler cap. By the time I've finished, I will have a very standard looking A1 ready to sell

I'm glad to know what this project consisted of. But I'm sure you will be happier.

Now it's time to make changes from one bike to another, which I suppose the radiator protection would have also thought about.

As well as other parts of the bike that I cannot see because of the position of the photos.
