Tensioner rattle temporary fix

I have a rattle coming from my tensioner dampener due to cracked and damaged bushings. I have the new bushings ordered (Powerflex) but I needed a temporary fix to get rid of the rattle and provide extra safety because this is my daily driver. Here are some pictures of my solution. I used two large zip ties looped around the back of the tensioner bracket and pulling the dampener tight to reduce movement. The fix worked, the rattle is gone and I have some added confidence that it's safe to drive until I get my new bushings.

Nice fix, but you do realize that the damaged damper "bushings" at the ends will not cause any harm. They will only rattle a bit.

The main reason I did this was to minimize the rattle. That was accomplished. I have also heard of the bushings wearing away enough for the dampener to come completly off of one side and come in contact with the crank pulley causing damage. In any case, my powerflex tensioner bushings will be here tomorrow.

Good luck with the Powerflex bushings.
Here's a shot of mine after 12,000 miles.



They were installed along with a brand new tensioner. I still need to contact Powerflex to get their take on it.

Thanks for the heads up on the Powerflex.

Wow! Please post here after you speak to them about this. So I guess what you're telling me is that I'm just going to another temporary fix. LOL

That's a bummer. I thought the powerflex would be the last bushings I would have to buy.

OxyBluecoop, I know you said the tensioner was new when you installed the Powerflex bushings. Did you happen to test the dampener for it's resistance prior to installation? It sounds to me like you may have a faulty dampener. If there's no resistance with the dampener, the bushings will wear out quickly.

Just a thought.

Actually that would be the opposite as the damper would have little to no force being applied to the bushings if it was defective.

The retaining bolt is larger than the damper end, so it should never be a problem of it coming off of the tensioner body.

I don't have any tensioner issues. I was considering replacing my bushings with Powerflex.

Jinz68, I installed the Powerflex tensioner bushings today. They lasted about 50 miles and were torn apart! That sucks!!!

I guess it's time to order a whole new tensioner. How did you fix your situation?

Oh no!! Did you take a photo of the shredded bushing? If so, send it to Powerflex UK. I sent them the photo of mine last night. I'll post their response.
I just sucked it up and bought another OEM tensioner assembly.
MINI really need to make the damper a seperate part.

Good Luck!
Jim

Jim, I haven't taken it apart yet but I will take pictures when I do. I just ordered a new tensioner assembly a few minutes ago. I found a company on EBay selling them brand new for $139 + $13 shipping.

Please send me the reply from Powerflex, I will really appreciate it!

Good price!
I'll let you know what they say.

This does not look good! I bought a set of Powerflex bushes earlier this year from Detroit Tuning. I live in South Africa so it cost me quite a bit with the shipping and exchange rate. I hoped this would be the solution as I have tried making my own nylon bushes etc without success. The powerflex bushes disintegrated in a few hundred miles, see pictures.

I arranged a warranty replacement set via Powerflex USA to collect whilst I am in Tulsa on business at the moment and I received it. Looks like everybody using these bushes are getting the same failures? Was interested in going Powerflex for my front lower control arm bushes but now I am not so sure. Ended up buying a new tensioner, just to get the little damper. So STUPID that the damper cannot be bought seperately.

BlueMax, I would post my pictures that I took today but it's pointless, just look at your pics and they're the same. Did you have any problems getting a refund?

As far as the other bushings from Powerflex, I'm happy with them. I have the engine and transmission mounts installed. I don't think you can go wrong with their other bushings. The problem seems to be with the tensioner bushings only.

Any information on the warranty transaction between you and Powerflex reguarding this issue would be greatly appreciated.

Let me say I also have other Powerflex bushings on my car and have had NO problems with them. In fact, I just installed the rear trailing arm bushings yesterday.

Thanks, good to know the other bushings are good.

I did not get a refund, I received a replacement set from Powerflex USA. Seems like I need not even waste time installing them. Powerflex stated that I had seen this type of failure once before, seems like it is a regular occurence! Contact is Brain Fowler: brian@powerflexusa.com.

I also replaced my tensioner, and at the same time, I replaced the stock bushings, with powerflex. They lasted a week. Now they are destroyed. Now I am putting the stock bushings back on. I only paid $89.79 for my tensioner assembly. Brand new from rockauto.com It says it is a Gates on the website, but has the same markings "litens" as the OEM.

Good find!

Mini/BMW is an A.S.S. for not making the strut/damper available as a separate part. For $90 I can buy 3 1-foot long strut/dampers for my VW.

I've sold several sets of these this year and only had 2 sets fail and those were just recent. I've got some customers that we installed them over a year ago with no problems. So this is something recent and specific with these for the tensioner. If any of our other customers have a problem, please let us know. Both our customers that had the issue fall under the powerflex warranty and we have them taken care of with refunds, or exchanges.

Maybe it is a bad batch of poly-urethane. Anyway I got the exchange set straight from Powerflex and assume these are also recent ones. Probably not worth it fitting them, I suspect they will fail. I was so hoping these bushes would be the permanent fix!

Got a response from Powerflex UK:

"Hi Jim,

Many thanks for the picture

It looks like the material hasn’t gone off properly internally. This causes it not to harden and therefore fail prematurely. I can only put this down to a bad mix of material

We now have new measures in place that prevents this

I will get a new set out to you, hopefully I’ll be able to send these by the end of this week as we currently have no stock of this part

Kind Regards

James Bourn ~ Sales Manager

So, it looks like they are aware and on top of the problem.
Not sure if I really want a new set of bushings, though. I'd really like a reimbursement for the money I laid out for a new tensioner and installation.

Jim
