If it was going to be an issue within the shifter I would guess first of a problem with the index ring rather than the springs. I've gotten some Syncro 2 shifters before that had a thick wax like grease internally and IMO that could potentially gum up the indexing. As far as lube, I've used some with the wax like stuff left in place and others with a little slurry of grease and oil. I think it makes a difference in how the shifter feels, but not so much in how it works.

Anyway, you can take it apart and most of the time the index ring and springs will stay in place and it goes back together easily. I would take it apart, flush out any gunk and remount with a light lube.

Another thought regarding the rear cluster. Is your cassette spacing right? If you have another 8 speed wheel, I'd suggest throwing that on there to see what happens. One version of the Exa Drive cassette (where all the splines are the same size) had to have the cogs put on just so or shifting would be wonky.

I'll take it apart and have a go at cleaning and relubing to see what happens.

Now on the cassette point. This problem was there with the original cassette and original wheel. Then I got the Fulcrum 3's which the original cassette would not fit on. So I got a custom set of spacers from another Campagnolo owner along with a 9 speed Veloce cassette. Dropped the largest cog and then changed out the spacers. The problem is the same with this new setup.



So I'm pretty sure it's in the shifter. I did source new springs and even they index ring if needed. I'll shoot for the lube job first then if that doesn't work I'll order in the parts.

I appreciate all the help on this.

Well, I took it apart. It was just like the first parts diagram posted early in this thread. I found dryed up grease that was more like wax now and rusted looking springs. On spring rotated freely where it mounted into the carrier but the other was bound up pretty good. Even after cleaning out all the old grease. For now I took it all apart, cleaned it really well, regreased it, and put it back together. I used white lithium grease because it was lighter than the Park Assembly grease I also had on hand. Got it back together no problem and it appears to be indexing properly. But I'm too dizzy right now due to sinus medicine to go for a test ride. Even if it all works great now I'm going to order and replace the springs. It was a very easy job and I shouldn't have been nervous about opening it up.

Here's a quick shot with the cellphone camera of what it looked like when I took it apart. None of that gunk in there was really grease anymore.



A big thanks to everyone that helped on this thread. Hopefully later today or tomorrow I can get it out to test it.

Well, the clean and lube didn't do the trick so using the info provided earlier in this thread I ordered in some of the new right indexing springs.

Got the original sealed box in, marked as right index springs and with the right part number.



Took the shifter back apart, pulled the first spring, and it was like...huh?? Did I screw up and order the wrong thing????

I checked the diagrams and ordered the right part as long as everyone is right about the new part number cross referencing to the old one. And that's what the package says I got. But the springs appear to be just the opposite of what I need. I am just having a stupid attack here of did Campagnolo put the wrong springs in the box?



The vendor was totally cool when I called them and are reordering the springs. They said they'd check them before shipping this time. Anyway, what do the experts say. Did i order the wrong ones or did Campagnolo package the wrong ones?

Thread dig.

Hey ​​​​jamesdak did you ever manage to get your Campy indexed DT shifters working?

You ordered the wrong ones, kind of, in the early days of Campy's indexed shifters they used the springs that we now call left. That applies to the Record DT shifters and 1st gen Ergopower brifters. I'm not sure about the dual mode DT shifters, but I suspect they're the same. So you needed EC-RE210.

Amazing timing to happen to see this right now. Just had this problem with my 1992 stubby end 8s Record Ergos. The "right-side" springs I ordered for the right brifter are not correct, in that in the 1992/1993 (at least the 1993 spare parts catalog too), the springs go in the top of the carrier as you're looking down on it in the brifter. On the later models the springs go in upside down before inserting the carrier. So just as mentioned, for certain older rear shifter models you need the mirror imaged part, or what is now called "left". Good thing the OP compared springs first. If you install the wrong ones like me you get a big gap in the middle of the shifting (smooth parts of index ring) and rebuild it over and over until you compare to the old springs... And I now know that includes the Record DT shifters, have to file that away somewhere. Thankfully they're not too costly, my "left" springs for my old right brifter are supposed to be delivered today.

P!N20

Yeah I first discovered this was the case when a mate of mine sat down with me to rebuild our Ergo brifters with new g-springs. Mine were 1st gen and his were a bit later. When we got to installing the new springs I knew something was wrong and couldn't figure it out, but my mate's went together no problems. Took us about ten minutes to realise my original g-springs were the other way around.

AJI125 

I was also rebuilding a Chorus 10 shifter around the same time. It wasn't until I did that one with the upside down spring carrier that it planted the seed. But I've got a long email string with a very helpful online supplier who steered me clear of ordering a new ratchet etc. until I figured more out. Thankfully one of my last ditch efforts before ordering some good looking early style 9s Ergos I saw was to tear it all down one more time, and I still had the old springs over on the corner of the workbench. Held them up and... Eureka!

Thanks for this thread! I am about to launch into my 8 spd 1st gen Ergos to find out why they are not as smooth as my 10 spd 2nd gen Ergos. Good to know about he interchangeability of the springs. Hoping everything else is Ok.

AJI125 

Which year/model Ergos? If you check the diagrams, they should be clear which springs you need depending on the spring carrier orientation. See diagrams below for 1993/1994 when it appears the change from "right side up" to "upside down" was made. I should probably not call it right side up since it was only used for the first couple years but when you open it up you'll see what I mean. And if you look careful, you can see how the 1993 are mirror image springs of the 1994! Most of the other parts seem the same.

Here is the 1993 diagram showing the flat "right side up" carrier. Assuming you're talking the right side brifter, you'd need left springs for this arrangement.


And the 1994 Record Ergos (same arrangement for all models, but may be different part #s ). This matches the rest of the future orientation, so you'd use the right side springs for a right side brifter.

SJX426 

AJI125 LOL I don't know the year! They were purchased of ov CL or the Bay, don't know which. They have been working but I think they could be smoother. I suspect dried lubricant. I didn't take pics but IIRC it may will be the first.

P!N20

Good summary AJI125 , I also note that the diagram illustrates the left brifter.

See post #44

It's also worth noting the part numbers for g-springs changed over the years. So if you're looking for g-springs for right or drive side indexed downtube shifters or Ergopower brifters up to 1993 you need at least two units of any of the following part numbers:
7260108
SL-RE009
EC-RE210*

If you need g-springs for your left or non drive side Ergopower brifters from 1994 onwards, you need at least two units of any of the following part numbers:
SL-RE010
EC-RE209*

* Not recommended.

jamesdak 

Wow, I never did finish this out. Off the top of my head one thing of not was that modern g springs do not work properly in these. I kept getting ghost shifting under power. Got an old school campy guy that let me know this and the proper springs to get. They've been working flawlessly every since. Can't seem to find the right part numbers tonight but I can dig deeper if it matters to anyone.

P!N20

That's interesting. The part numbers are above - post #37 , from earliest at the top to the latest at the bottom. I wonder what the difference is? They look exactly the same.

jamesdak 

Ok, I kept digging and found the info. You are correct by the way. Originally I was getting all these response that all g springs were the same and ordered the ones for modern ergolevers. They seemed to fit just fine but were not quite as strong as needed. Then Ol' Tater on Paceline hooked me up with the right part numbers which do match your info above.

This is how the bike ended up with some modern Fulcrum Racing 3's and using a cassette spacer mod kit to rebuild a proper shifting 8 speed cassette for it. One of my favorite bikes now.

P!N20

So just to be crystal clear, the SL-RE009 and SL-RE010 is correct, but the EC-RE210 and EC-RE209 are not recommended (for the earlier stuff), is that right?

I'll have a look at when the EC's were introduced.

This is awesome, I feel like I'm getting closer to getting mine working.

jamesdak 

Yes, that was my experience. When I went with the newer springs at first they seemed to fit fine and work on the stand. But when riding and apply average power I was getting ghost shifting on the rear. Once I put in the correct "SL" series springs my problem went away and has never came back.

AJI125 

Awesome, thanks for this! This is even better info. I'll plan to pick up a set of the SL-RE009, I can see the spare parts catalog transition 93-94 that there's a difference in the springs from the Ergos to the DTs (with the 93 Ergo springs matching the DT springs, while the 94+ Ergo springs don't match the DT springs). Now that I know to look for it that is! I'll see how the newer springs go when I install them, but having the right ones in there would help I imagine. I'm going to have way too many G springs around the garage, better make sure to start labeling and putting these things away!

P!N20

I'm going to try this again.

It's also worth noting the part numbers for g-springs changed over the years.

...................................................Left - NDS ...................................Right - DS
Downtube shifters ..............................N/A ................................7260108 or SL-RE009
Ergopower up to 1993 ..............SL-RE010 or EC-RE209* ..............SL-RE009 or EC-RE210*
Ergopower 1994 .......................SL-RE009 or EC-RE210 ................SL-RE010 or EC-RE209
Ergopower 1995 onwards** ......(EC-RE110) or EC-RE210 .............(EC-RE109) or EC-RE209



* I've had success with the later g-springs in my 1st gen Ergopower levers, so I've put them here.

** There were different g-spring part numbers for the 1995-1997 models in brackets, but they don't seem to be readily available.

Boy am I glad I resurrected this thread. For the past twelve months or so I've been having sleepless nights concerned with my 8 speed shifters not working - felt like I tried everything, but I could not get low gears to hold. Got to a point I swapped them out for friction shifters so I could ride my bike.

Then jamesdak mentions the newer g-springs aren't strong enough to use in the downtube shifters. I was skeptical at first, (they look exactly the same!) but took the 'old' g-springs out of my dual mode shifters (which I use in friction mode) and put them in my 8 speed shifters.

Went out for a ride this morning. Click, click, click, crisp shifting, no slipping. Found a big hill, low gear, rock solid. Tullio be praised!

So big thanks to jamesdak for providing the solution that was sitting right under my nose the whole time!

jamesdak 

Glad to share the same help I got. The real credit goes to "oldpotatoe" over on Paceline who hooked me up with the correct springs. Pete's a wealth of Campagnolo info.

I know this is a really old thread but I am having this problem with my 1993 ergopower shifter on my Lemond. Unfortunately, I am having lots of trouble finding the appropriate part and was wondering where you get your old Campy parts from jamesdak.

P!N20

Which part are you after?

gkamieneski

JamesDak, you just have to find a set of Ergo 8s, perhaps on the bay. You’ll love them!

I too have a set of wheels with Veloce 9sp spaced for 8 speeds with the Wheels MFG kit. I know Campagnolo made a kit as well but now it seems that neither may be available (I wonder if these conversion kits could be duplicated, perhaps out of Sch40 PVC?).:Recently though I went back to my original 8 speed race wheels (Chorus hubs with GL330 tubulars) and I have to say I missed the guaranteed shifting performance of Campagnolo 8 speed with an 8 speed chain. There’s something about how a Campy 8 sp drivetrain shifts and performs under load.

Oh, and the Chorus Ergo 8s that I found on the bay from someone in Germany make it even better.

kpark517

Looking for the SL-RE009. I guess I could find a used shifter and take it apart.
