As I look at the pic I'm not sure I see item #34 which IS NECESSARY. ......lm

In any case thank you all for chiming in about this. This thread started when I was just doing clutch work and made the discovery. I left the wire in place at that time. But since then, I've disassembled the entire bike...48lesco wrote:Bob750 if you're still with us... No, that's not normal:)
As some of you may have seen in my rebuild thread, I cut off that rat's nest and removed the bolt. It was a mess in there.
I've since Heli-Coiled it and all is well with that part of the situation. See?
And I did enjoy reading the debate about washers. Yes? No? Spring? Lock? Flat? I don't think anyone mentioned Washer, Plain, which I tend to think is just another word for Flat. But all the talk got me thinking.
Up until now, I have been planning on putting a 6mm spring (lock) washer under the bolt head (as is called for in my CA77 manual -- "Reference 33. Washer, Locking") to ensure the bolt doesn't move, what with it being subject to rotation (however slight) by the movement of the Primary Chain Tensioner. Now I'm not so sure because of this debate.
I've tested the installation, and it looks and feels good to me with a lock washer on it. Without, it feels naked. The way I see it. If there is no washer and the bolt becomes loose, we can guess what would happen, right? If there is a washer, there is very little chance, if I torque it properly, that it will loosen. But if it does somehow back its way off, the risk of a loose lock washer floating around the case is trivial compared to a loose 2-inch bolt (which would have to come off before the washer fell away anyway) floating around in there. Either way there is hardware floating around and no tension on the PC. So I tend to think that putting a lock washer at that location is the most logical solution. It bites the distance piece and the bolt head, putting tension on them. It also presents a smooth surface to the tensioner arm--at least smoother that the six sharp points of the bolt head.
There is this though: the part number in the catalog isn't 94111-06000 (Washer, Spring, 6mm); it's 90432-259-000 (Washer, Locking). This suggests to me that it's not just a spring washer as I'm intending on using, and it's not a tabbed washer if the drawing has anything correct about it. So it could be a washer of similar design to the one that goes under the 4-lobed primary chain drive sprocket nut. But such a part doesn't seem to exist anywhere any longer. So is my spring washer gonna do it for me? Or should I wing it without? Who's buying the drinks if my wife's Dream throws a primary chain? ;-) I can tighten in well enough either way I suppose now that there's a stainless steel Heli-Coil in there.
I hope no one minds me reigniting this thread. I'm sorry it dropped off my radar!
