Poll - Torque limiter failures on 449/511

I went to test a few more TL's and found that Andy took my jig. I will have to order another one. I will note that the TL I sent to Kelly was 280 ftlbs.
Hopefully it doesn't sit around for 7 months...

So you are saying that the factory test procedures and etched number marking system in Newton Meters on every Torque Limiter is meaningless?

Or is that The Kymco factory or BMW, Huskqvarna has released a bunch of mismarked Torque Limiters out on the open parts market that are nearly twice the breakaway rating of the designed rating limits of that part. Come On?

When I see one Factory marked that high I will believe it and concede and appologize for doubting this.

So if we all buy them we should then disregard the factory rating marks that come on each 1 as BS and buy them from you because ?

How much are your KYMCO factory made special ones?

Have you had your Torque Wrench professionally calibrated and tagged lately? Or would those calibration stickers on the torque wrench be meaningless also?

I have my Snap-on dial face with follow up needles, Torque wrenches calibrated every 6 months. Its an old habit from back in my FAA Airframe/Powerplant Wrenching days. It was required then and I still get it done every six months through work for Free.

OK. OK. No hard feelings! Never was.

Since I have actually replaced a few of these Torque Limiters. I didn't get that my own experience was so off track and confusing, It's given with some merit I would think. As pictures and factory markings and ratings were referenced and also actually photographed off my own, on hand parts. Its a shame for me I suppose, being so hard on my own equipment that I had such failures as nobody else has rang in here with anything to actually contribute other than a NO answer to this Poll. I do feel like the "Odd Man Out" sort of. Especially now.

Now that my own skepticism has offended some or actually got some conversation going. I see that any doubt of the standard accepted practice of believing everything you here is the "Norm" here on the 449/511 Site and is clearly not welcome. I thought I had made a valid request of simple verification, many times. Just as you would get with whatever you are paying for that has an actual performance rating. Like a dyno sheet for instance, this is why they mark these things (torque limiters) after testing them.

I'll still be shipping my spare engine to Tinken to have his team go through it and do all the Mods. I just have a skeptical nature. Is that so bad?

As for the special part reference, It was a figure of speech only. I just figured he must have a special lot of these original torque limiters on hand. I've seen the picture of the half full boxes myself about 20 times, wasn't there even a mention of a torque limiter party or something.

I assumed if he had them with such high breakaway number ratings and was shipping them out as he did to you, they had to be from Kymco, BMW or Husky. I would buy one myself.. If the price is comparatively reasonable but I guess you couldn't compare it to anything else. Since Tinken is still in the developement stage of a proprietary design of a trick replacement component of his own manufacture. I welcome its introduction to all of us. Probably more than you could imagine and I have respect for him doing that. After all I could use one myself of all the members here on this thread, thats obvious.

I realize and appreciate the fact there could be many variables during the testing process and am open to the specifics. Like Ft. lbs. and Newton Meters being one of those variables. Or soaking it in Oil for instance. Or turning it the wrong direction during the test itself. All could be relevant questions or variables. Whats wrong with asking for these specifics.

I'm not stupid but any of us being treated in a condescending manner and in a patronizing way doesn't help any of us on a shared information forum.

I'll try not to mistakingly enter into this threads conversation discussion again. I'll just be reading from the outside as other opinions of actual parts in hand and experience on having an actual couple of Torque limiter failures being contributed to this discussion is looked down on and in BMW "German" terms "VERBOTEN".

I am German, BTW part of the definition on my I-phone of that word on one of the Online Community dictionaries says "all definitions are approved by humans before publishing. Any promotional content will be deleted". Since I'm clearly not promoting anything here but my own opinion, I get it. I thought that an opinion was allowed in this discussion. Skeptical or not! Lets bring it all out in the open so we all learn from this without a bunch of secrets. I like things that way. I must have picked up on that notion during my education years. It would then be an "Open discussion" thats what information forums are all about.

The threads title did infact ask for a Poll of Torque Limiter failures to answer with a "YES or NO" and if "YES" to please list riding conditions and mileage, thats it. I did.

I think You and I "Kelly" were the only 2 who had checked "YES". Aren't we lucky? Thanks for allowing my opinion to be expressed here.

I never was upset. That's just Me. Bye Bye for now.

Part of a post from another website look at the date below. Its from a discussion on the BMW G450X. Good information. Nothing new just an "Old Problem" us G450X Owners have dealt with for years. Guy was from NSW in Australia. This was one of the positive experiences for this owner. Not my words just added for information and reference. This was posted originally on Jan. 20th 2010. So we G450 riders were dealing with this for some time.

On a different note....

I may have mentioned my bike started making a whyning noise whenever the enging was reved/ridden up to 3-4K RPM.

It started suddenly ofter a long (400Km) ride whick included a fair amount of hard pack, rock, sand and tar road sections.

The noise was the same as the bike has always done under deceleration but was now louder and constant and seemed to come from the clutch area.

I pulled out the clutch - it was fine but the gear it drives, known as the torque limiter or idler gear was off centre! WTF

Dropped the engine out, the only way to get the side case off and removed the gear, spun it on it's bearing and yep, it was RS, quite obviously (but the bearings were OK).

Took the offending part to my dealer and the mechanic agreed instantly that the design should never allow this to happen and he would support a warranty claim for it even though the 70 Hr service was not done (the bike is now over 140Hrs).

3 weeks later the new torque limiter arrived from Germany and the problem is now fixed

The torque limiter is a short shaft with with 2 gears on it and a bearing at eacg end. In between the 2 gears are metal shims which can slip and dissipate excess touque in the drive train thus protecting the engine/gearbox if the rear wheel suddenly jars, bites or locks (this is used in the absence of a cushioned rear hub)

Mine had obviously done it's job but somehow the large gear went of centre.

Interesting to note: the spare parts guy at my dealership said the computer system shows the torque limiter part number in a different colour which means one or two things: A) the part is now made by a different company or B) the part has been revised/modified.

He could not tell which but the new part looked different in that the part number etched on it was in a different font. Otherwise it looked identical.

I have also read that a couple of bikes in WA have done the same or similar but the reported fix was to replace the torque limiter bearings.

To do that the torque limiter must be dissassembled so I question the acuracy of that report and suspect the problem my bike had was not unusual.

The torque limiter is worth $333.00 at the time mine was replaced. Side case gasket kit $95.00. [End Quote]

I hope this doesn't offend anybody after I said I wouldn't engage in this thread anymore but the above added post does show that there are others in the world that have had to deal with Torque Limiter issues of various types long before Husky riders had to deal with it. BMW had a revised part number for Torque Limiters already available before the end of 2009. Notice the owners bike hours after repair at 140 hours. He was happy and got taken care of by his BMW dealer.

I've heard of countless stories that were the opposite of this but don't want to post any negative information on here any further.

My own posted specifications given earlier in my posts on this thread were from a late 2010 3rd edition BMW CD service disc. The bike was only produced by BMW in model years 2009 and 2010. Yet were sold a bit before late 2008 and after as stock dwindled into 2011.

Husqvarna obviously inherited the problem and like "Tinken" said were told by BMW to fix it. I'm surprised the Husqvarna owners haven't had the same experience some of us BMW "Outsiders" have had. Especially those who started off buying the Husky's back in model years 2011 and on.

Hope an outside opinion other than my own can shed a little more light on this. 5 1/2 years later and it still seems to be a mystery to some?

I still love the bike though and its a damn good engine.

Good ??

Has anyone tried a cushioned hub and locking the TL solid?

Love new parts hope I never need to buy one though.

Similar Nm to BTs items (227.3 Nm - 167.6 ft/lbs)

It is possible I guess, Moto.

It would depend on their combination of additives in their oil.
If the TL is indead like a LS diff in operation, certain additives may be bad for the grip of the plates.
The wrong oil in an LSD will reduce or stop an LSD from working. In those cases, sometimes a change to the correct oil can bring them back.

Not sure if the same would be true for the TL, but you raise a good point! Would be worth checking with their help-line.
Engine oil wouldn't normally have any concideration for limited slip type operation.....

Been on a 5 day vacation, no phone service. I don't believe Maxilube slipped your TL, I have been using it in my 511 for 2 full years.

OMG Where is your second butterfly????

Sure seems like a lot of grief to go through every year or so.
I asked this question the other day and I'm still wondering if a cushioned rear hub would solve the problem?
Even if you had to change the cushions at every tire change?
Is there just so much strain on the transmission etc because of the crank direct mounted clutch that entire engine revolutions need to be slipped away?

Time to get the die-grinder out there !
