Welded Cush Drive?!

<< < (3/3)

McCabe-Thiele (Ted):
Daft idea but could you not just leave it as it is or is there too much risk to your other driveline parts?

Bryanj:
Without the cush bit it will eat chains and put extra stress on the transmission

sye:
Why would anyone do that in the first place? Is it damaged beyond repair inside?

I think I would replace it rather than go to the trouble of separating the two as there's no guarantee that it would be usable.

No knowing why someone did that, might be as simple as the rubbers were worn out or missing and replacements weren't available or when needed the owner just couldn't be bothered but could weld, or it might be a right mess in there. With rear wheels of most descriptions for the cb550 being a bit thin on the ground its probably worth trying to correct it, but if it were me I'd be just as tempted to search out alternative wheels, cb650 costars fit without messing around as I recall, and when I last looked were a bit more affordable, finding just a rear alloy to match what is there would require luck. I'd be reluctant to run with it as it is, vibration can be destructive, at least I wouldn't want to ride hard without some damping in place, though many newer Hondas just use a rubber bush on the studs that carry the sprocket, not sure if the picture isn't loading properly or just not showing the studs to hold a sprocket in place, I don't suppose they modified it to have rubber bushed studs like on newer Hondas? Still leaves potential pitfalls changing bearings- that said I've  done massive mileage with a sidecar adding loading and have yet to need new rear wheel bearings, plenty of fronts been fitted over the years, not rests though.
