clutch hub nut

[dwilliamsx6]

I got an 06 K9 with clutch issue. Long story short... the infamous clutch hub nut loosened up. I pulled it all apart and it seems that everything is factory with no updated parts but nothing looks broken. So my question is... can I just replace the nut with the new one? What are my chances this will work without issues? I really can't afford the updated hub, basket, etc right now so if those of you with more Dog experience think this is a bad idea I will sadly park it until it can be updated. Thanks DJ

What was/is the issue you were having?

Many of us are still using the original hub

could not find neutral, bike would lurch into gear and creep with clutch pulled. tried adjusting it and changing fluid as per many other postings but nothing helped. finally i pulled primary cover off and what was happening is that when i pulled clutch lever the entire clutch hub assembly would move 1/8-3/16" before clutch would start to move, this distance was just enough to keep it from fully engaging. upon disassemble i found the nut backed off, hoping i can just put a new nut on and be back in business.

If your basket isn't broken, and all the parts look good, you can just tighten it down. I'd suggest you get a new nut from Curtis at Wild Steed Worx as they're cheap and hardened now. Use red loctite and torque it to 150 ft lbs. Yes, very tight. You want no movement at all. Also a good time to replace the seal between the tranny and primary. Those two parts (3 with the o-ring) should be less than $20 shipped. Let that red cure overnight before you fill the primary and ride it.

While your in there, and waiting on a new nut. Pull the clutch plates out and measure the thickness if the whole stack. Should be 1.960. Write your measurement down, in case you have problems adjusting the clutch when you get it back together, we can better serve you. Also in the primary backer plate, in the middle on the top, there is a vent. Make sure it is clean.

Agree with all above^^

thanks, will do. The clutch stack measurement, is that just the frictions or spacers too. by the way it is a 12 disc pack not 9, does that matter on thickness?

Both friction and steel.

9 or 12 doesn't matter. But on these 05+ that clutch stack height unfortunately especially on the 12 the optimal range is narrow for it to be spot on!

Replace the washer under the nut with hardened one. This is the probable culprit in the hub nut issue.

hello all, just got my new parts.. bunch of seals, new nut and washer. cleaned everything up, reinspected, all looking ok, clutch stack measured 1.955, this ok? also I forgot stacking order, steel first or friction first on stock 12 disc?

don't forget to clean that little breather vent in the back of the primary---mine was all full of crud.

1.97"-1.98" is ideal. Might be worth your time while you have it apart and go up a little on a steel. Measure the Steels individually and see how they each measure and I would just increase the smallest one by .025 to get you back to that top end range of 1.98". It will make adjusting the clutch easier and last you another 20k+ miles just taking care of it now.

Steel goes first then Friction. Thickest Steel goes first!

Here is another recent thread with lots of good info for you to read!

Rebuild or Replace

After reading up on all the clutch experience posted here I decided to take the clutch apart on my 07 Mastiff to see why I’m dealing with the dragging at stop, slipping in 3rd, great when it’s cold but not when it’s hot issues. I found I have a 12-Disk clutch that at first look seemed pretty...
