Veek Torque Values

[Paz324]

I'm thinking about trying out the gear change enhancer on my 2017 DL1000 to see if it eases the clunk between 1st and 2nd gear but before I even entertain the idea of removing the rear wheel it would be nice to know the torque values for the rear axle and sprocket.

Any info would be greatly appreciated.

The book says 100Nm. That is a problem though. Many people have reported the nut cold welding to the axle. They are stainless steel and SS like to gall under pressure. What has worked without a single problem reported is to apply anti seize to the threads and torque to 80Nm to account for the lubrication effect of the anti seize.

Thanks greywolf, do you have any values for the sprocket nuts ?

[greywolf]

Good question. The book values are too high there. Use 115Nm on the large front sprocket nut and 50Nm on the rear sprocket nuts. The front also specifies high strength thread locker but medium strength is fine and will make removal easier.

For some reason, though they are the same part, the DL1000 has more power and the DL650 has a bent washer to hold the nut in place, the smaller bike has a much higher torque specified for the front sprocket nut. I recommend going with the DL1000 spec for both.

The rear sprocket nut book spec of 60Nm is just too high and has caused stripped threads. Use the generic value for a "7" marked 10mm fastener instead.

Thanks again, I'm not sure where manufacturers get these values from sometimes..

The Tracer 900/FZ09 I had before said something crazy like 80nm on the rear sprocket nuts which stripped out one of my nuts and caused some damage on the stud so I ended up using nyloc nuts at 60nm.

Hmmm... Interesting post. I have just bought the gear change enhancer and I spent the best part of a day just trying to loosen the axle nut !!!  A few heat and cool down cycles and lashings of WD40 and it eventually gave up and I won ! Boy was it on tight. So I'll be doing the rest of the work when I get some spare time. Thanks for the heads up about the torque settings Greywolf !

Check that the threads are in good condition. They may have been galled instead of just being tight.

I got the axle nut off today, threads were fine. Gear change enhancer is now on, although I haven't had time to try it out yet. I tightened the axle nut back up to 100nm. Quite a fiddly job getting the slack correct on the chain, It would tighten up every time I did up the axle nut. Got it correct in the end though. Checked the bearings while the wheel was off and they seemed fine. Serviced and cleaned the rear brake caliper an checked the pads. Next job front caliper and pad check.

I don't know if you missed what I said, but 100Nm has caused galling. Anti seize and 80Nm has never caused a problem.

[Simmo24]

No, didn't miss that. As the threads were OK when I got the nut off and it had been tightened previously way more than 100nm. I decided to stick with the setting without anti-seize.

[greywolf]

Just know you are taking a small chance doing that while using anti seize and lower torque is a sure thing. Compare enough problem reports for me to make a sticky thread at stromtrooper.com with zero problems reported using anti seize and lower torque. See http://www.stromtrooper.com/general-v-strom-discussion/23698-rear-axle-thread-galled.html

OK, good point, I'll breakout the Copper grease and re-do the nut to 80Nm. I wanted to do the chain again anyway, it seemed really tight when I was sat on the bike even though I set the play to the settings in the manual.

[Simmo24]

Well, I loosened the rear axle nut again re-checked the chain, then used copper grease on the threads and tightened to 80Nm. I must admit it didn't seem long before the torque wrench clicked, so I've marked the position of the nut with a sharpie and will check over the next few weeks to see if there is any movement.

[greywolf]

The nut is a Fuji style locking nut with sheet metal tabs putting pressure on the threads. No one has ever reported it moving on all the sites I follow.
