Cam chain tensioner

[orlandopalladino]

I got around to removing all the panels predatory to opening the rockee cover to correct the cam chain slippage, and noticed the chain tensioner.. It looks to be mechanical. I thought there was a recall to go to hydraulic. Anybody know anything about this?

What year is your scoot?

 

[orlandopalladino]

2016

 

[orlandopalladino]

It definitely is a mechanical tensioner. It looks nothing like what is in the BMW parts catalog.

That year should have been hydraulic I believe.

 

[orlandopalladino]

It definitely is mechanical. It looks totally different than what is in the parts lookup.

Hi, im having an issue with the tensioner. Did you replace it by yourself? I would like to do it myself but have no experience whatsoever. Hopefully someone here will help
Thanks, Ben

I am only half way through. I have the replacement parts(400.00$), and have the stuff under the rocker cover. The bolt next to the oil filter stripped out slightly, and I have held out installing the hydraulic parts.

Thanks for your reply Orlando!
I just spoke with the dealership and they told me that my only option is replacing it with the hydraulic one. Around 900$ parts and labor.
I don’t know why replacing with the mechanical one is not an option.

There is only one video on YouTube and this guy is just swapping the tensioner in a minute.

That is what I was quoted. It frosts me that BMW does not pay for this. It was covered by an NHTSA recall, but they tell me my particular serial no. Was not part of it.

 

[Bojan Gjoshevski]

Yes, I read that somewhere. They say that the models after 2014 have updated mechanical tensioner and they have not been recalled so far. But I don’t understand why I can’t just replace the part with the same mechanical tensioner.

I would not trust the mechanical tensioner. Mine has failed me twice.

What are the signs of failure?

 

[orlandopalladino]

The bike suddenly stops, and a compression check shows no pressure in the cylinders.

That’s the end result but what are some early signs? I got a 2013 with 12k miles on it.

 

[orlandopalladino]

I had no warning. Some on this forum have reported a noisy valve train as a symptom, but I had nothing to compare against.

Este es el sonido previo al desastre

The tensioner on my 2016 Sport started making a rattling noise with a cold engine (went away after a few minutes) after only 2,000 or so miles. Dealer serviced it under warranty, however recently it started becoming noisy again, at around 8K miles, so I will need to check the paperwork whether they just replaced it with a new mechanical one rather than hydraulic. I would hate to have the engine self destruct over this one part.

It's in Spanish, but you can see what he is doing.
