I have a chrome Paramount and am having a rear changer problem.
I wanted to put on a type 1 Campy Rally rear changer, but the threads on the changer do not screw into my frame. I pulled out a type 3 Campy Rally I have and it screws in but the stop does not aling with the protrusion on the frame correctly .

I want to use a type 1 but I need a differnent bolt?

What do your paramounts have for rear changers? Pictures?
Where can I get a bolt?

Also, the cable guide clamp to route the cables around the bottom bracket, I am not sure how it goes back on the bike??? Any photos?

My 72 came with a Gran Tourismo which I changed to a Nuovo Record. Campagnolo threads should fit Campagnolo dropouts... pictures might help solve your dilemma.

There is no difference between the threads of the two rally rear derailleurs. Without having the pieces and bike in hand it would be near impossible for us to determine what is going on. So either the threads are damaged on the type 1 or???

Thanks for the photo but I am still stuck.

See, I can't say if I have a Campy dropout or not. I know the G3 Rally I have fits, but I can't say if the G3 Rally changer has a Campy thread bolt in it because it is used. I do not know if they made two diff bolts for Rally changers. I can for sure say the G1 Rally i have will not fit, but again i do not know what thread it came with becuse it was used also. However, it was NOS so the bolt is GOOD.

As for the cable routing bracket question, your photo is to far away to see yours.

Hi Jeff,

The standard derailleur mounting bolts (both Campy and Shimano) are M10 x 1 (10mm diameter, 1mm between threads). My '72 P15-9 came with the Le Tour GT300 (Shimano Crane) RD, and I replaced it with a 2006 Campy Record long cage; both derailleur mounting bolts fit the Campagnolo dropout derailleur hangar bolt hole perfectly. I've never seen a derailleur mounting bolt with any other threading (not saying they don't exist).

Attached are photos of the bolt from the Crane derailleur and the derailleur cable guides.

Well, when i held the two bolts up to each other it seemd there was a difference in the threads. But lets say there is none. The next question is, what other changers can i steal a bolt from for my G1 Rally?

If the bolt is not stripped (have a photo?), have you tried removing the bolt from the derailer, and threading it through the rear side of the dropout with your fingers? Emphasis on the finger-tight only part - you do not want to risk damaging the thread of the dropout - provided it is not damaged already (not that I am saying it is).

If you have a LBS nearby, they should have an assortment of derailleur mounting bolts. If that's not an option, I have an old POS Campy Gran Turismo RD, and my guess is that the bolt will fit your Rally.

I'm concerned, though, that the bolt hole threads on your dropout hanger may have stripped threads from someone trying to force the wrong thread bolt.

If you'd like the Gran Turismo RD bolt, PM me with your mailing address.

Great photos. Thanks.
I just could not see how the cable routing bracket was routing the cable over to the front changer. I will install mine like yours and see if all works.

As for my bolt, I will be trying the measuringthing and thrading it in from the back of the hanger to check as described.

My Paramount is a 70000 series frame if that helps anybody. There may be a "G" in front of that number. I personally do not know when it was made but the guy I got it from in CA bought it new and he is about 85 now.

Jeff, I don't have a clue what a 7000 series frame is. Could you post a photo of it, or at least post the serial number?

I think the bolt you need is Campy p/n 3456, and the pivot bolt on the Gran Turismo deraiiler I have is considerably longer (the derailler body where the pivot bolt goes is much thicker than the Rally body), so I don't think it will work.

Again, you might try your LBS to get the right bolt, or some of the mail order businesses that specialize in small bike parts.

The photo you have here is what i am calling a 3rd gerneration rally changer. I have one of these and its bolt has the right threads or should I say goes in nicely. But its bolt ca not be used with a 1st gen rally. The head is larger for one thing.

The 1st gen. does not have the letters down the back like this one. It just has the word Rally down the body. Don't know where to get a photo of it however.

The diagram Stan posted is of a first-gen Rally derailer. A third-gen looks like this:



Do you mean the 2nd gen Rally RD as below?



-Kurt

The illustration above is from the 1976 Campagnolo catalog No. 17a, but the 1974 catalog No. 17 shows the same derailleur as catalog 17a, with the same pivot bolt (p/n 3456). I'm not sure when the Rally RD came out, but the previous catalog (catalog 16, 1968) does not have a Rally RD in it.

A later Rally RD is shown in the 1986 catalog, and it does use a different pivot bolt, p/n 3506.

Yep, that is it. I have two of the 2nd gen changers. One with a bolt that does not seem to want to fit the hanger of my Paramount and one without a bolt(if anybody has one, contact me please). my 1st gen(thank you for the correction) changer's bolt screws in fine.

I do not have anybody around here to get a bolt from or talk to and Loose Screws only lists one bolt with no photo so I am not sure if it would fit. Seems like he is listing for a newer changer.

So I at least need one 1st gen bolt and to try to get some more info on the bolt I have to figure out why it is not screwing in.

Well guys that is what I need. I need at least one pt # 3506 bolt cuz i have one changer without a bolt at all. Then I need to figur out why one the bolt I have is not going in.

WHERE CAN I GET A BOLT??? No where around here.

Does anybody have a cross listing for this number CA-1100310, that is referranced as a 'pivot screw' by Loose Screws? In all the pictures that were shared, this number does not show and Loose Screws is not replying to me to learn more about their offering.

The bolt in the "2nd Generation" looks the same as one from a Nuovo Gran Sport: if so, a Nuovo Record will work as well.

Jeff,

I can't make any promises, but my LBS has lots of vintage small parts, and I'll run over there this afternoon after the owner finishes his errands (the counter clerk said he'd be back about 2:30) and scrounge through his parts stock to see if he has p/n 3506 or something else that might work.

I'll let you know if I come up with anything.

EDIT- Dbakl is right; the same upper pivot bolt (p/n/3506) is used for the Nuovo Gran Sport.

Sounds good

I have a set of bolts from a Nuovo Gran Sport if nothing turns up...

Did you confirm you need a bolt for "2nd generation?"

Yes it is confirmed that i needed a 2nd gen pivot bolt. And yes I would like to get yours because i have another 2nd gen rally changer that has NO bolt. I will PM you

Jeff,

Bradley, the owner of my LBS, had an upper pivot bolt for the Super Record RD, and the p/n is 4004. The differences between the bolt for the Rally and the bolt for the Super Record are that 4004 has an Allen hex socket instead of a hex bolt head, and it's made out of titanium instead of steel. It's a much nicer part than the 3506. He did not have a steel 3506 he could sell me, but he took one out of a NOS Rally derailleur he had and we verified they are identical except for the Allen head and the material.

The Super Record Ti bolt was more expensive ($18.00), but I went ahead and bought it. If you want it let me know and I'll mail it to you and you can send me a check for the $18.00 when you get it. If you don't want it, don't worry about it. I'll keep it; I'm sure I'll find a use for it.

I'll take it if Jeff passes, Stan.

-Kurt

Thanks, Kurt. He has first dibs, but if he doesn't want it, it's yours. It is a gorgeous bolt (jeez, I never thought I'd ever say that about a lowly bolt).

What's a CHANGER?
