Record Exa-drive pawl springs are toast
LBS cannot locate springs for this hub. They tried fixing as best as they could, but it is “skipping” again, randomly.
Anyone have a fix?
Apparently the 9-sp and up parts are not compatible.
Thanks!

Looking in the 1994 spare parts catalog, they should be correct for an 8-speed hub.
Campagnolo Spare Parts Catalogue - 1994 Product Range page 43

I had not been able to find that parts catalog!

Found them here in USA with the Campy part number! $8 each instead of £15 each, thank you so much!

You could try Merlin Cycles in the UK. They seem to keep a lot of stock of old Campy stuff and were able to repair my circa 2000 Ergo shifters.

But thank you for the suggestion!

You may need to question your LBS's motives. If they are in QBP and there's a Campy reference as well... just saying.
Having just rebuilt several 8sp and 9sp Campagnolo freehubs, I can confirm that the 8sp uses 3 individual springs with 3 pawls whereas the 9sp uses 3 pawls with a circular spring. Both require periodic cleaning with light lubrication (usually a thicker synthetic chain lube).

Perhaps ypu could point me to a Youtube tutorial or overhaul reference? it would be much appreciated!

Most freehub videos are for 9 speed Campy and Fulcrum freehubs. The only one I know for 8 speed is here,
.
It will show you how the pawls and springs are inserted but the author is reluctant to mess with the 2 sealed bearing inside the freehub. If your's still seem smooth, I wouldn't mess with them either. If they are grinding or showing play then you would have to punch them out and source and replace them. The inboard bearing is a particular pain because a circlip needs to be removed and then it has to be punched outward in the same direction as the outboard bearing. Often it is only the outboard bearing that requires replacement fortunately and you may be able to avoid dealing with the circlip.
9 speed freehubs are much easier to work on as the pawls usually stay in place under the circular spring.

Perhaps! I usually do my own work, but I could not find any rebuild instructions on this freehub. Plus they have given me some freebies, so I thought I would give it to them to them to repair. I AM curious that I, with this forums help, was able to find the part, yet they could not.
Perhaps ypu could point me to a Youtube tutorial or overhaul reference? it would be much appreciated!

One of the best sites to get Campagnolo information is Campagnolo's own support site. They have parts catalogs that go back to the mid-90's, and have the technical manuals for setting up and overhauling most of their components. Unfortunately it seems like they have trimmed down the tech manuals to cover only the last couple of generations.

Definitely. I had meant to mention this. Also, sometimes you can partially withdraw the freehub, put the tool on the pawls, and avoid some grief removing the freehub.

Also, doing the disassembly and reassembly inside a medium sized clear plastic bag can help contain the pawls and springs should they have a mind of their own.

It's not uncommon that a LBS isn't able to find odd ball parts, particularly for Campagnolo. Few shops see Campagnolo gear come in, even fewer are actually fluent in it. I know my favorite LBS always likes to see my bikes because they are about the only Campagnolo bikes they get in the shop.
One of the best sites to get Campagnolo information is Campagnolo's own support site. They have parts catalogs that go back to the mid-90's, and have the technical manuals for setting up and overhauling most of their components.

My LBS, and the head mechanic are pretty well versed in Campy, is an authorized repair, and has the full Campy took kit. I took them for their word, however TWO people mentioned a bike part distributer that has them. So, not sure what to think; they do a lot of volume so it cannot be that, unless the owner had a “falling out” with that distributer = Quality Bike Products!

Ah, yes! I recall the mechanic mention dental floss when he first rebuilt the freehub. I am guessing you wrap a couple of times, then pull free when reassembled. Also thanks to Ross200

Done! Thanks y’all!
New springs installed! The LBS had replaced the outer sealed bearing in the freehub. I made a holder with a pvc coupling. I used a pre-tightened zip tie, held in my teeth, to hold the pawls while i wound dental floss under the zip tie. Remove the zip tie, insert the freehub, and unwind the floss. Of course, it took a few unsuccessful attempts until i made the holder!
Thank you to everyone who contributed, even the dude who said buy a new wheel!

I pushed a paper towel down the “holder”so that the top of the freehub was just above the top of the pvc holder. that way both hands were free to hold the pawls in while i dropped the zip tie onto the freehub body and work it down to hold the pawls in.

That tool is interesting. Nothing like the locking loop spring tool that cam with my 8-speed with the individual pawls/springs.
