Nuovo Record - chain keeps coming off jockey wheel - help please...
Hi
Looking for advice - on my daily ride - a late 60s lightweight with mostly Campag Nuovo Record my chain keeps coming off the jockey wheel, this is usually when I am just riding along (not changing gear) although more often than not it happens when I am peddling faster... any thoughts?
I did think it might be down to a worn out jockey wheel and when I looked on line the images tend to be of fat teeth for a new one and thin pointy ones on a worn wheel - mine appears to have no teeth... is this because it's so worn or is it a different design?
Also if I do need a new jockey wheel - where can I buy one that will fit?
Thanks in advance...

Your pulleys, if original Nuovo Record, should have at least some teeth on them. Make sure they're not earlier, Record or Gran Sport pulleys. Some of those were smooth but usually made of metal. Do they have Campagnolo embossed on them and made of plastic?

Only time I had the problem as described is when the pulleys were worn out.
I agree, fresh pulleys. I have used the units at Performance bike to good effect.

Bent cage, tight link in chain?
Jockey wheels are pretty generic, don't need to find Campagnolo ones. Bullseye was the hot 70s replacement, but lots of options on ebay.

I do agree it sounds like new pulley time. The bike didn't suffer any kind of trauma lately did it? No reason to suspect a bent RD or hanger?

Looks to me like the pulleys are completely worn out. But check the things listed by Dbakl as well. Also make sure the hanger itself is not bent, as mentioned by Bianchigirll, which it could be if that derailleur ever took a side hit at some point.

Right, but Bianchigirll may be right as well. Let's see a picture from behind the derailleur. Point the camera straight forward so we can see if the hanger is bent.

The picture isn't good enough. Position the bike so it's vertical. The cogs should be vertical, and the cage of the derailleur should be vertical such that one pulley is directly under the other. I want to see all the cogs, allthe gaps between the cogs and the derailleur, all at the same time.

Jeeze, you don't want much, do ya Tom. True enough though. Hard to tell on derailleur hanger alignment without a well-lit full shot. Taken from dead on behind.

OP, please don't take this wrong, as I don't know your experience level, and I'm pretty new to using Campagnolo myself. I have that same NR derailleur, & when I first got it, the pulleys were literally hitting the cage, from built up crud, like grease & road grime. After I cleaned them good, I also found a cracked pulley, which is a pretty common problem, I found out, from reading. I got lucky & found an old Victory RD, with the white-ish pulleys, for a good price, but I see some folks charge a pretty penny for Campy-marked pulleys. Anyways, that's a basic starting point, but from here, it looks like yours are pretty worn. Good luck.

You can use shimano pulley wheels, and they're available cheap. Try here: https://www.ebay.com/itm/SHIMANO-UPPE...item1c2ece51c5

Thanks - that is very useful – i'm fairly new to this world – bought this bike last April and have been riding it to work most days since...
looks like a strip-down and clean up could be in order.
I was looking at Tacx Jockey Wheels for a replacement - only about £10 on Ebay...

I'm kind of with you repechage - when I bought the bike it had 90s Shimano brakes, headset and crank and after spending a lot of time getting it all back to original Campagnolo I wouldn't want any Shimano back on the bike.
But it seems there is other aftermarket stuff out there...

Eh, just sand off the Shimano logo if you have to.
