Lock washers, or no?

I'm not seeing a clear view in the AIM unless I'm missing it.

Also, use blue threadlocker?

Thanks!

Re: Lock washers, or no?

Those look like they could be "prevailing torque lock nuts. You can tell if they require a lot of torque to fasten. If so, they don't need any thread locker.

Check out the 5th nut down on this page: https://knappfast.com/fastener-knowl...s-of-locknuts/

Not sure about the type described in the article, but some have a threaded hole that is alightly triangular shaped instead of round.

Thanks! As near as I can tell, they are originals and are just plain nuts. And so far I have not found a specific instruction on those in the manuals so I don't have a torque value for installation. It's been 8 years since disassembly. THOUGHT I had taken enough pics at the time but we all know how THAT goes. ��

Got to say I'm not a fan of the AIM. Not user friendly.

Just clean up the threads and torque to whatever the spec is for that size bolt. Sure wouldn't hurt to use some thread locker.
