I recently installed the Hayden Tensioner on my 2012 Ultra. I seemed way to tight when installed and only had 1/4" gap instead of the 3/8" gap as shown in the installation instructions.
I contacted Hayden with my concerns about it being to tight and was assured and according to them all was good and normal with my install and after 300-400 miles my shoe would seat in with the chain and the gap would increase to the 3/8" spec.
Well she whined (whirled) more than I expected and again was assured it would quiet down and loosen up after a break in period of a few hundred miles.
Approximately 2,500 miles later and the whirling noise never went away. At this point Hayden stopped returning my messages for awhile, longer than I cared for at least.
I pulled the primary cover and removed the Hayden Tensioner and found what I would consider excessive amount of wear in the shoe especially when you compare it to the original HD tensioner shoe that had almost 30K on it.
Here is the Hayden with approx. 2500 miles
Here is the stock unit with almost 30K
Which one is to tight??
I contacted Hayden and sent them the pictures, explained once again my concerns about the chain now being to tight using their product and asked for a refund of my purchase price or at the very least replacement springs and a new shoe. Below is the reply I received form Hayden after making numerous attempts.
We're sorry for the inconvenience you have experienced. I will
certainly be sending you both a replacement shoe and set of springs. You
have done everything correct in installing your M6BT07 on your bike. The
only other option you might have had is to remove the inner spring and
loosen up the tension just a little. You would then only need to be
aware of your mileage as to when you would need to add the inner spring.
While this is not the preferred install, we have had some customers
report to us it helps.
I will be putting the replacement parts in the mail in the morning to
the address listed below. And again we apologize for the issue.
For grins I put only the outer spring back in as suggested and then bottomed out the shoe using vise grips. As you can see in the pictures the spring bottoms out before the shoe even hits the plate leaving a gap of slightly less than 1/8". That means that with the original 1/4" gap that Hayden states is normal and fine there is only about and 1/8" of movement before the spring bottoms out and there is absolutely ZERO play in the primary chain. That can't work. What happens when the primary heats up and things expand?
Even using just the one spring as now suggested is not going to fix the issue.
I can appreciate them replacing my parts. What I have a problem with is that they are choosing to stick their heads in the sand and act like there is not an issue with installing this newly designed tensioner on some newer model year bikes. I simple online search will bring up similar results with the Hayden Tensioner and no official statement from Hayden on the problem or fix for it.
I have pulled the Hayden Unit and MAY try it in the better half's 08 model and see if it is a better fit for her bike. It will not be going back in mine, no way no how.
For now I will run the stock tensioner and am considering modifying it by welding it in place so it cannot over tighten the primary chain. There are some threads on the HHT site explaining that modification if your interested.
I believe Hayden has a great product that works for the majority but if you have a newer bike you may want to take a closer look before jumping in the water. And yes, the whirling has decreased since going back to the Stock Tensioner.
