2018 MP3 500 Front Turn Signal Replacement
i broke my front turn signal on the above bike and purchased a replacement. i cannot figure out how to remove the previous one...much less install the new one.
The new one is threaded but has a post that appears to make it impossible to screw it on. (see pic) Gentle attempts to try to unscrew the previous one or pull it off have not produced a result.
i called my dealer and the service tech said "I have no idea...we work on about one of those bikes a year".
Can someone offer how to do this? and please try to provide detail....often I read on this site explanations of how to approach an issue and I am lost...often there is an assumption you know certain things....that is not me
Thank you
Mark

Greetings:

Usually posts like that one serve to ensure the orientation of the light is correct on its axis; i.e: Facing straight forward.
There is surely a nut on the inside of that fairing somewhere that you thread onto the wire, then tighten up the assembly to fairing side.

If it's just the clear plastic front lens that's broken, why not just replace that from the new one?

To replace the entire turn signal assembly, you need to remove at a minimum the windshield and the plastic V portion. This gives you access to the electrical connector.

There is a very skinny nut that is hidden that scews onto the threaded part. I found that using a very skinny bicycle tool (I think 17mm) slips onto the nut perfectly to allow removal. This saves you the time to remove the whole plastic front end.

Thank you all for your responses.
Response 1 - It appears you are correct.
Response 2 - I was considering replacing the lens...and still am....there is a scratch that you cannot see in the picture so I perfer to replace the entire thing uness it is a monster of a job.
Response -3 Thank you for the detail
A couple of questions:

V shaped ?

Could you send a picture of the bicycle tool you are talking about and the size socket. This will save me multiple trips to home depot.

Again thank you all. I was about to give up after searching and asking everywhere.

Forget Home Depot or Lowe's or any other hardware chain since you will probably not find find it there. The tool I am referring to is only found in bicycle repair shops.

I use this specific one made by Park Tool. It is perfect as it slips behind the plastic fairing and does not interfere with the tilt lock arms or other components. There is hardly any room up there, hence why hardware stores are very unlikely to have this. I bought mine on Amazon. Pretty inexpensive if I remember.

The V shaped piece is the trim that runs from between the headlights to the top of the dashboard, just underneath the windscreen (see pic)

Hi
I took off the windshield but my 2018 does not have the V piece in your picture. No does there seem to be a simple way to remove the back plastic piece shown in the picture. from the link (for some reason it no longer lets me upload files....thoughts?

Your V piece is painted in green to match the body color. Other than that, it is the identical same piece. It just pull out at the top on both sides. Be a little careful though as it is held in by friction using pins and rubber bushings.

Once you remove that piece the rest is fairly straightforward.

If you are going to remove the black dashboard piece shown in your pic then you will need to loosen the 2 Torx screws located/hidden in the glovebox.

Thank you.
Again brilliant. I would have never guessed the v shape part of the front end was a pop off item. I "carefully" removed it to take a look at it this morning with the windshield still on just to see. I understand why the thin 17mm wrench you sent the link to is the only thing that can get in there.

The link below is to this morning's pictures.

Once I loosen the nut, what prevents it from falling down into the fairing? Is there a way to prevent this?

Thanks again. My friends are following this thread and are seeing how much more helpful and knowledgeable you are than the response I got from the local dealer.

Nut on Wire?
Greetings:

I would think it will stay on the wire bundle based on your pic? You may have some fairing dismantling to get to connectors.

That hole is nothing more than a observation hole.

To R&R the turn signal assembly using the wrench I mentioned, you come in from underneath through the wheel well.

This gives you the most leverage with the special wrench. Once the nut is loose, it will still be attached as it sits on the electrical pigtail wire.

Disconnect the plug at the main wire harness, then come in underneath the wheel with a 2nd hand and catch the plastic base piece, spring washer, and nut with one hand as you pull the old turn signal out with the other.

That is the shortcut way of doing this job vs. the PITA way by removing the whole front end.

Understood. Thanks.
I put my hand under the wheel and could feel the nut.
Tool comes in this weekend from Amazon.
Is there enough slack on the pigtail to disconnect and reconnect? I imagine this will be done blindly by feel?...



Also...thank you Wheelman-111

Please upload to the MV servers - if you find it won't let you try resizing the images to max 800px on longest side.

FAQ: How do I upload a photo?

To access the electrical connector, you will need to remove the flat black plastic piece that sits between the V piece.

It just takes a few screws. Just keep track what goes where. As I stated earlier, there are also 2 hidden screws inside the top glove box. They are all Torx IIRC.

Just take your time and be patient. If it isn't coming out easily, you probably forgot to loosen something.

Don't break or force anything, otherwise it will start geting expensive.

Once the flat black plastic piece is out, you have free access to the electrical connector for the turn signal.

This would also be the ideal moment to check the tilt lock fluid level. Look for the small round plastic brake reservoir looking affair. And if your bike is a 2018 or older, then I would suggest just to suck out the fluid and replenish with fresh DOT4 using a disposable syringe.

Thanks again.

I am taking your advice and proceeding slowly and cautiously.
See the attached photos. Are these all the screws I need to remove?

Yes. If I'm not mistaken...
This will remove the glass fixing panel.

I removed the 6 screws I indicated in the picture and gently tugged on the large plastic piece and it does not remove. Most likely there are other screws....any thoughts?

The screws holding the little DRL light need to come out as well. Hold the DRL while removing the screws to prevent it from getting damaged.

The 4 screws indicated by the red arrows do not need to be removed. The 2 screws inside the glovebox DO need to removed.

Once the DRL is out, then you will probably see a couple more Torx screws that holds the base of the black plastic piece.

Sorry. I completely forgot about this "smile" headlight. Disassembled these parts many times. Hands remember, the head does not. The manual describes the stages of dismantling .... P.S. I sent this message three times .... There is a bad internet in our country.

First, Thank you for all your time, help and advice. You did not have to take the time to navigate me through this and you did. For that I am grateful.

I have decided that this may be too much for me. I can see you understand these types of things and they come easy to you but (as I already knew) they do not to me. The more steps there are the more potential I see of me losing screws or things not getting put back together properly. I already lost one of the windshield spacers and have to wait 2 weeks for one to be ordered. I am going to quit while I am ahead and just change the lens and accept the scratch on the housing for the light.

Again, thank you. You have been great!
