Belt Tensioner

F3-T OEM drivebelt vibration damper

I-Day said:
I bought a 2016 F3T in March and have a big trip coming soon. My belt starts to vibrate at about 70 mph which is the speed I like to cruise at. I talked to my dealer about putting on a belt tensioner and he recommended tightening my belt a bit which should move that vibration out of my sweet spot. Does this work?

Answer from Can Am customer service regarding their OEM belt damper accessory... didn't even mention their OEM damper... wonder why? Next to last paragraph answers all and any questions directed to customer service. Give em a call and confirm you have a problem. Enjoy the free vibration massage while riding in belt vibration range. :gaah: BTW feel free to refer to case number. She is an erudite BRP guru... you can tell by her answer to belt vibration issue.

"Good day Mr. A*****,

Thank you for taking the time to contact BRP.

In response to your request regarding the vibration on your F3 Spyder, please note that the Spyder drive belt is a tensioned string system that transmits the drive pinion torque to the rear sprocket via the tension of the upper part of the belt.

The natural response of a string system is to vibrate when stretched and released at different speeds and strengths. The accumulated energy of these movements in the belt will be dissipated throughout the entire vehicle through the drive pinion and the rear sprocket.

We suggest you contact your local BRP dealership, they might be able to adjust your belt to displace the vibration, but it will not eliminate it as it is normal for a belt-driven vehicle to vibrate.

Should you have any other questions or comments, do not hesitate to reach us by replying to this email or call us at 1-888-272-9222.

Once again, thank you for contacting BRP.

ALL Belt Dampeners are Placebos, in my opinion, after 7500 miles of " Tweeking" tests on my 2016 RT Limited. Belts flex, stretch, expansion, contraction, under different loads, such as acceleration, deceleration, different speeds, wind velocity with Wind Screen up or down, up hill, or down hill, and tires wearing, changing the original balancing! Sorry, but there are no permement " Fixes" to eliminate Belt Chatter Vibration completely on these Spyders with long belts, as BRP Customer Service Rep. confesses! Drive shafts work well on motorcycles, but they are much shorter lenghts. If they were long, like on Soyders, then even the Drive Shafts would need to be balenced, and the Differential Gears would also need balancing and service. So, for those of us who are too old to handle Two Wheelers, then we either have to accept the Vibration factors, or,.........buy a Motorized Wheel Chair. ( Personally, that option is on hold for me. ) I had a BRP new 1973 Three Cylinder Free Air Two Cycle Snowmobile that ran like a Raped Ape, but was belt driven. The Vibration over 50 MPH was massive, even way back then, but it was the fastest Machine money could buy at that time. No one minded the Vibration when they could get that high speed. But, if "Some One" comes out with a conversion kit that totally eliminates the belt vibration, COMPLETELY, on my Spyder, for $500 or less, and instals it under Guarantee, I will be one of the fiirst in line to purchase. BRP will never change from their Belt driven system. They will keep passing the buck to the Dealers who will keep BSing the new owners unfamiliar with the problem. It is not a Safety problem, so BRP don't need to address it any more than they already have, by their Plastic Dampener device.

My last 3 H-D's were belt drive. No vibration!

I just don't understand why these machines need a belt tensioner at all .! If Harley has the same final drive system with no vibration then is there an engineering issue here ..??!
Sorry for the rant, but really why is there an issue with this on these very pricey machines..?
BRP want to chime in here ..?
Thanks for allowing me to express my opinion here .!

So this kit will fit the F3 Limited? Your site is really unclear by not listing the Limited series, only the F3 model. Thanks.

It is exactly the same setup whether a F3, an F3-S, or a F3-Ltd. 2015-2017 Guess I should add "All F-3 models". First time that has ever come up. If you order, use a big computer. The smart phone function will not work correctly.

I have the same question. Would like to see pics and install would be awesome

While we haven't actually videoed our Damper install for the F3's, we felt the one Lamont did for the BRP one was good enough, and our kit mounts exactly the same way.

Here are where our videos are located. Work your way through them. Be aware that some information has been superseded as we refined things. I guess I can do a video, but it may be a while. Kinda busy..... btw: Out of all of the F3 kits here and abroad we have sold, no one has had any trouble installing them.

We are getting ready to start offering a new, easier way to align the pulley. It is pretty easy to align the pulley and adjust tracking all at one time. More about it when we launch it. I tried it on a RT today and it worked perfect and was very accurate.

I don't know about tightening the belt but an idler works. I have the BRP idler with over 9000 trouble free miles on it but there is a HUGE discussion going on in another thread about upgrading BRPs idler to two bearings or buy Docs. This will be a never ending topic until BRP offers a more resilient solution. My thoughts.

I watched a you tube video on installing this. It shows it mounted on the top side of the belt. How does this help with belt vibration being on the top?
If it does, great, I will probably get one. Just wondering.
thanks

The top of the belt is like a guitar string vibrating and the damper is like pressing a finger on it and stopping it.

This is my first post here. I had my maiden voyage traveling 330 miles yesterday, we visited Crater Lake and Diamond lake. I have a new 2016 F3 Limited. After doing some searches on here, I now know this crazy vibration is fixable. I was about to call the dealer to start asking. Love the forum. So my question is, there is a lot of recommendations on here for the tensioners, but seems I am limited due to my model. Looks like my only aftermarket option is the Smoothspyder. Has any other owners of a 2016 F3 Limited installed this? Any feedback? Thanks in advance.

I have a 2016 F3 Limited and have the BRP tensioner (aka idler pulley). It removed the vibrations. Very easy install. $40. I have 3000+ miles on the tensioner so far.
 
I have a 2013 Spyder RS-S and would like to find a tensioner for it. I am new to the bike this year and could hear/feel something but not able to put my finger on what it was. I now understand that it has to be the belt vibration.

There are dozens of hits when you google Harley Drive Belt Vibration - it's a problem but the engines on those shake so bad most people don't notice the belt vibration.
 
Bought mine from Doc.

I didn't even consider any other damper than Doc's. Very happy with it. The kit comes with everything needed. It was an easy install too.
It was bought in late May and has over 34,000 miles on it, no problems.
Buy Doc's, I think it's the best.
