Mystery Part

[Rockitdoc]

OK, so the fear I have when disassembling anything mechanical for the first time without adult supervision is that when the mechanism is opened several tiny little springs will shoot out in all directions never to be seen again and worse, that I have no idea where they belong or what they do.

This just happened.  Removed the primary chain cover on my '85 RGS1000SFC and the spring/retainer-looking bit below fell out as the cover finally let go after much wedging and coaxing.

I can't find a reference to this bit anywhere in the shop manual or an exploded drawing showing where it goes.

So, three questions:

First; should it just fall out when the cover is removed?
Second; what is it's purpose?
Third; where does it go?

1. It often falls out when the cover is removed.
2. it keeps the primary chain tensioner under slight pressure so it doesn't flap around.
3. Self-explanatory... it fits under the tensioner blade.

I had a girlfriend who used to use things like that to hold her hair back

G'day Rockitdoc,
Its the primary drive chain tensioner spring.
It will fall out if you take the tensioner out, which is par for the course when you take the primary cover off.
It holds the tensioner against the adjuster bolt so that the adjuster doesn't rattle around if the chain is a bit slack (or something like that).
It fits through the hole in the tensioner, around the tensioner shaft and against the primary cover (the curve end presses against the primary cover).
Remember, it doesn't apply pressure against the chain but against the adjuster bolt.

Once the chain is tensioned there seems to be less need for this part. I decided it was too much of a hassle to keep track of and have not had it installed in my Jota for the past 5K miles or so.....

The spring seems it could become a bit of a hazard - do many of you leave it out?

 

[The Three Dellortos]

No.

 

[sfcpiet]

Why should it be omitted? ???

Easy to install, and once you know it is there, you don't tend to lose it either!

Reminds me of a bobby pin, if you left it in your bathroom, within a little while days it'd be in your wifes hair.
