250-500cc WR primary nut. Check the torque!!!

Hey guys I got a little scuttlebutt on the primary nut on the WR motors. As some of you may have read, the primary nut on my 2012 300 backed off inside the motor and caused some havok bouncing around in there. Husky warranteed the parts and my dealer took care of me on the labor cost.

Soooo... Apparently someone from Husky recently picked a random bike on a showroom floor (not sure what dealer or what state) and took it apart and found the primary nut finger tight!
You dont want this thing backin off the threads and bouncin around in there, trust me.

Can you get to it just by pulling the clutch cover (like you can on a 610)? Is there a "bendy-tab" lockwasher behind it?

That was a common problem on 2006 610's to the point the woodruff key would shear and you would get the "rumble strip" effect of vibration. It happened to mine. I removed the cover and sure enough, that bolt was on finger tight..................Seems like a common Husky QA issue to me since IT KEEPS HAPPENING.........Looks like the motor assemblers needs some refresher training.

You have to remove the clutch cover
