Exclamation Rear axle thread galled

Yep, another rear axle with galled threads. Went to adjust the chain and right away noticed something wasn't right when trying to loosen the rear axle nut. It wanted to seize but I was able to get the cheap ass Suzuki slotted nut off. Sure enough there are several axle threads that are galled. Ordered a new axle and the self locking dual-star nut. I will not torque this up to the 72.5 foot lbs that is the spec, will probably torque to 60 foot lbs. After doing a bit of research I know I am not the only one with this problem, seems Suzuki has been selling quite a few rear axles for the DL650. Never had this happen in 35 years of riding motorcycles. My Wee is a 2006 and two weeks out of warranty but I called Suzuki anyway. Their response is there is no known issues with the axle (expected response) and bike is out of warranty but take it to a dealer and 'maybe' it will be covered as a good will gesture. I just told him all I wanted was a trustworthy fix to the problem and don't really care about the expense I have incurred. Right now the bike is out of commission until I get the new axle installed. After that I will take pics of the bad axle and give them to the dealer when I show them the bad axle. Don't have much faith that Suzuki will do anything for me though. Just out of curiousity I have thought of getting the bad axle tested for hardness as there are an unusual amount of these failing and I wonder if there are a bad batch of axles out there. Anyone had experience getting steel tested? Even with a Rockwell hardness test result I wouldn't know what values wound be acceptable. I'll probably just end up with a new axle and Dual-star nut, go with a lower torque and call it a day. But I sure am curious.

One solution is to use anti seize on the threads to prevent galling and to lower the torque to 55-60 lb-ft to allow for the lubrication effect. I have yet to hear of a single problem after doing it.

Pat- 2007 DL650A was ridden to all 48 contiguous states. 2012 DL650A didn't quite make it to 17,000 miles.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014+ DL1000s. Wee = 2004-2011 DL650s. Glee = 2012+ DL650s

Pat's solution is one method. I went with the big honking nut from Holeshot.

Thanks Pat, think I will use your solution. Anti seize with the combonation of the dual-star nut torqued to 55-60 looks like the winning solution.

I have seen a galled axle with dual star nut. Anti-seize use on it is unknown. I've been using a Holeshot nut for 3 years, since the time the problem happened to me.

Tom, I'm just curious, what locks the nut?

There is no mechanical stay on the Holeshot nut. It has more thread contact and shouldn't be a problem. Stock Stroms outside North America do not have cotters in most countries.

Pat- 2007 DL650A was ridden to all 48 contiguous states. 2012 DL650A didn't quite make it to 17,000 miles.

We've got lawyers designing bikes, I think, and they've got us by the nuts.

As Pat said, the Holeshot nut has significantly more thread surface area than the stock nut. I always torque it and it hasn't ever loosened. I'm willing to bet that the stock OEM crown nut wouldn't need that cotter pin if the full thread surface area were available.

I have a spare Holeshot nut and there are ten threads to fully grip the axle. The OEM nut has five. The threads where the flats have been cut on the OEM nut are useless.

new axle for me too

I have a K8 DL650 which was last professionally serviced at 25,000km.
It now has 33,000 km.
I went to have my rear tyre replaced after 16,000 km only
to have the mechanics tell me that the axle was stuffed.

It was all they could do to tighten the RHS nut with one holding
the bike on the lift, another holding the LHS bolt and the third
guy putting everything into tightening the nut up so I could
ride home and think about what I wanted to do.

I elected to have new chain and sprockets as well as the new
Heidenau and axle; the bill was AUD $1111.

In retrospect I think I could have got another 10k km out of the
chain and sprockets.

Here's a pic if I can work it out.

Incidentally I also had a K4 and was adjusting the
chain and tightening the nut with a torque wrench.
Subsequently after riding the chain went tight on me and I'm
now sure that that axle was also galled !!!

Combination of torque wrench use and Suzuki's too high torque spec are what cause these problems.
If you just do it by feel you'll be better off. The vast majority of stripped thread problems happen to guys with a torque wrench in their hands.
