| Hey BladeRunner,
I read this post and both the ringing and the scuffing sound very familiar. I have an Ergo with a TT46. Perhaps our experiences are the same; I'll relate mine...
Scuffing happened to me first. I discovered that the starter hex adapter (possibly the wrong name for this piece), which is attached to the shaft the clutch rides on by a set screw, had slipped. This let the shaft and clutch bell fall a bit, so that when I turned the transmission without the engine running, the top of the clutch shoe assembly would scrape on the clutch bell. At idle, there'd be a constant scrrrrrraaaape sound that sounded like a bad bearing, but of course this all wouldn't be a problem once the clutch was completely engaged. Anyways, it's a rather annoying problem, considering one's choices in retightening the adapter (that I found, anyway). Your first option is to remove the engine, so that you can push up on the shaft from inside the clutch bell and then go through gear mesh and realignment pains AGAIN. Your second option is you can remove just the adapter, pull up on the shaft, then very carefully and gingerly lower the adapter onto the shaft and hoping it doesn't fall down a bit again. SOME falling is completely unavoidable I think. And ofcourse then you have to tighten the adapter's worm screw through the holes in the frame. I chose the second option to avoid realignment hell, and when I was finished, the unavoidable downward movement of the shaft left me with about 1-2 mm of up-down play in the whole clutch/shaft/adapter assembly. Not a good thing, and I'm THIS close to biting the bullet and taking it all apart.
As for the ringing, I notice it most at idle or when I've raised the engine to a faster idle, just prior to spool-up. I'm pretty sure that it's the muffler, as Doug mentioned, but it may be the clutch bouncing around at idle due to the play. Gee, wouldn't it be nice if the two sounds were related and stemmed from a single problem?
I hope this lends SOME insight, and I'd love to hear about further experiences you have with the ringing and scuffing
