2 different noises from 2 different bikes in 1 thread.

Can you help me with these?

1) The drivetrain on my Cilo is noisy, it almost sounds like it’s not completely in gear (Shimano 600 friction shift) but it definitely is right where it needs to be and it’s not that kind of sound. I think it’s loud pulley wheels What would cause them to be so loud? When I coast, it’s almost silent. Here’s a video:

2) When I push hard on the drive side of my old Raleigh I hear what sounds like a scraping sound? It’s not the chain rubbing against the derailleur, I’ve checked that. I can’t tell if it’s coming from the bottom bracket or what. Anyone recognize it or have an idea?
here’s a vid of it, turn volume up:

Appreciate any thoughts!

1) sounds pretty normal to me. but, it's a video and really hard to tell. check to see if the pulleys are not too worn down or missing teeth. try and post some close up pics
2) this is even trickier to try and diagnose on the web. it does sound a chain against the derailleur. but, you said it isn't, so...pffth. when's the last time you grease the BB bearings? how about the pedal bearings? are you rubbing the crank arm? does it make the sound when on a stand?

Clackety-whackety sounds like the normal cross-chaining sound.
Scraping sounds like the right crank arm hitting the front derailleur cage.. Check angle and high limit screw.

The chain isn’t rubbing, but I did find what I think the culprit is and I think I fixed it.

I assume it’s still possible to find replacement wheels for Shimano 600 6200 series derailleur?

Hehe no the sound it makes when cross chaining is very apparent. This noise is definitely coming from the pulley wheels.

BUT I think the scraping sound was the bash guard rubbing against the front derailleur which had kinda shifted down a little so it was hanging too low. So kind of a combination of everyone’s suggestions lol
I moved it and we’ll see if that fixes it!

Can someone point in the direction of where I can buy new jockey wheels for a 80's Shimano 600 rear derailleur?
