Stud Flnges broke

[shockmhd]

2 of the studs broke off on my hub.Stud pulled right out. No abuse,not overtightened,anyone have similar experience.Warranty covering it.I'm not a mechanic by any stretch of the imagination.Paranoid other side will break off when I'm out riding in the ginga weeds and.<br />
Thanks

Was this on your '09 TriGlide? How and when did they break off? Did the studs break off or pull out as in threads stripped? Was this just from riding? During tightening? During removal? Was your trike recently serviced or tires changed and if so by who? Need more info to give you an informed best guess.

Thanks for you're reply. Studs came out apparently while removing rear wheel.Threads stripped.09 Triglide. Bike at dealers going up this week to see for myself. Being repaired under warranty.Would like to know why studs came out.40K on bike. Also left shock broke(leaking). <br />
Thanks

The shock leak is in no way associated with the stud problem. Trike wheel is no different than an automobile wheel. Sounds to me like Godzilla with a 200 pound torque wrench put them on (as in over-tightened and the stud was stretched), or they were installed cross-threaded, or even driven on with an impact wrench....and even could have been the wrong size lug-nuts. The nuts were obviously galled to the studs, or the studs were defective. I know you said they were not over-tightened, but you would not know that unless you were the last one that put them on. <br />
<br />
I stopped doing tire business with a very good friend of mine because he insisted that all the tires he replaced in his shop were tightened down as tight as possible with an impact wrench. I told him that in the event of a flat, I could not remove them and my wife certainly couldn't. He told me to get a bigger lug-wrench and I told him to kiss by butt and have never been back there.<br />
<br />
You will probably never know, but it certainly is not a common problem and as long as you have a minimum of two on the wheel in a criss-cross pattern ...I would not be afraid to ride it as far as I had too to get to a dealer. Sorry....but this points to improper installation of some sort, or a batch of defective studs.<br />
<br />
Now...if you mean the studs "turned" in the hub...that points to the wrong stud being installed in the first place. All you have said is "threads stripped".

Is it the the lug-nut threads, threads on the stud, or the stud spinning in the hub?

</div>The Harley dealership thats doing your work can tell you more than anyone...hard to tell the cause. I never use an impact on trike wheels but use a torque wrench and torq the lugs to 80 ft lbs (this is what the conversion companies call for). Ive heard of some dealers using locktite on lug nuts for safety sake/liability, but some factory literature Ive run across (Honda) actually recommends doing the opposite and applying an anti-seize compound on the threads to prevent just such an occurrence.

I agree Zook.....80 to 90-lbs. is about the recommended torque for most trike kits I know of.

I have not heard about anybody recommending loctite on a lug-nut. That thinking falls in line with the tire dealer I mentioned above. He was more afraid of the liability if the wheel came off due to a loose ling nut than he was the customer being able to remove the wheel. Improperly torqued lug nuts will not only be hard to remove....they will actually warp a brake rotor, or ruin one of these alloy wheels.

I always torque them at 90 ft/lbs and then check them periodically, the manual for the Triglide says 90 - 100 ft/lbs and then recheck them in 500 - 1000 miles.

Yep....they should not be over 90 pounds-or-so and it's something you check during a normal nut-n-bolt tightening routine. If I caught anybody putting any sort of thread-locker on mine, or using an impact wrench.....I would hit him in the head with the biggest stick I could find handy and a baseball bat would be preferable.
