F3 idler pulley on an RT

[timeless]

Thanks

Spoke to Kathy and if you want to take it off and send it back, we will refund the part even though we state there is some noise due to the ribbed belt.

Thanks Doc, but this is NOT one of your units, it is a BRP chepo and I am paying the price for going that route!!!!!!

Ahh, now I understand more. So you just have our adaptor then! Well, i hate to say this, but our unit may not work any better.
However, with that being said, their pulley had .008 side to side play and ours had .001. It may be vibrating on the belt because of that play. This may be causing the excessive noise you are hearing. Since you already have the BRP one, you can order a kit #1 for the RT and use the existing parts and use our arm and pulley.
If you do that we will be willing to give you a refund if it is not better with our setup. I will tell you this; when we did that 2010 RT the other day you could hardly hear it. In fact, the customer said that the only time he heard it was slightly on deceleration.
If you want to return the bracket adapter instead, send us the email and we'll take it back. Either way you want to go.

Thanks again Doc,

I removed the pulley and popped the bearing out, I found it to be rough and I believe that is the cause of the noise. I have removed the grease seals and cleaned the bearing. I got some junk out of the race & balls, this must have been from the manufacturing process or just collected some dirt while laying around prior to assembly.
The bearing rotates MUCH smoother and will probably be considerably quieter now.

I am thinking about drilling the bolt/axle shaft & adding a grease zerk, just not sure i feel like going to all that trouble.

I will let the forem know if my repair is successful.

Thanks again Dock for your kind offer to help out!!!!!!!!!!!

From what you are telling us I'll bet they are not even ABEC-rated. Too bad out bearings won't fit, too big.

NOTE:
For those installing our adapter kits on the RT, the angle bracket goes under the flat bar and the slots on the flat bar go to the front of the bike. Note the video at 11:27

Belt Vibes

David,
Why did you take the smoothspyder off? I intend On installing Doc's kit but plan on keeping the smoothspyder on as well. Is the smoothspyder in the way?

My theory is that the smoothspyder will keep tension when letting off the throttle, and the BRP tensioner will reduce vibes while accelerating/cruising.

Take Care,
Louie

Hi, I have the aftermarket tenisoner and it works okay. This is the first time I have heard of the BRP model. But as reducing the vibration on deceleration, it is the top of the belt that tends to vibrate because the wheel works against the engine. I guess the REAL ANSWER would be to install an idler wheel somewhere between the front and rear sprocket. This way the vibration on both acceleration and deceleration could be addressed. Ron

Actually, the location for the BRP unit (with our adapter) and the one we sell are in the exact position they need to be. I don't jnow why the vibration is centered there, but it is. In fact, owning both an RT and F3, and having the damper on both I can tell you it works good at all speeds, accelerating or decelerating, and is even more effective on the RT. In our initial design we were going to move it closer to the center of the belt, but after testing, it was not necessary.
