Tourque arm - fazersharp - 09-05-16
Whilst I was refurbing my centre stand I decided to do the torque arm, one bolt came off ok but the other got rounded a little (Yamaha cheese metal) I have re filed some flats on to it but could do with a new nut, but what is it? its like a nylo nut but instead of the nylon it has a bit of metal that sort of digs in.
Also what torque should I re do at

This is from the service manual, but it's just a guide. Stick up a pic of the nut fella, I'm sure you can source a cheaper replacement.

Here it is and it fits on the bolt without a washer
Re: Tourque arm - fazersharp - 10-05-16
So what are these nuts called and I assume that any kind of torque setting is not really necessary on those nuts as
1 you dont want to end up snapping the swing arm mount
2 the nuts are designed not to come undone - self gripping with the metal slither
3 the arm is doing all the work and the nuts and bolts just hold it there.
What is the focer wisdom here
One more thing today is wet and damp and I have just sprayed the arm and the paint has gone matt, so I have re coated and brought it inside to dry

The nuts are usually called "all metal locking nuts" either The nuts are usually called "all metal locking nuts" either with a flange or not. There are loads of different types.
Try these:

Or Probolt do them too:

think that nut is 23NM. page 7-62 of the yamaha workshop manual
Re: Tourque arm - fazersharp - 10-05-16
Thanks chaps re- torque and nut supplier -- but my those are expensive I think though I have found the correct name for the type after risticuss pointed me in the right direction, they are called Satytite
Another question-- why would all metal staytite nuts be used on the arm as opposed to nylon lock ones

Just guessing tbh but I would say all metal can be undone and tightened many times while the nylock would need replacing more frequently

NOW THEN that may bring us back to this mamoth debate http://foc-u.co.uk/index.php/topic,14772.0.html, after all the workshop documentation not saying you need to loosen - it looks like the designers at Yam have designed into the arm a facility to enable frequent loosening and tightening suggesting that is what you should do. :lurk
