How critical is this washer? NR lever content.
I seem to be missing one. It’s not a lock washer. What is its purpose, and is it required?
TIA

Critical? You might get away without it but it is not a great way to build. Have a look at this drawing(part #2038 - lever bushing).

Suddenly I'm wondering why I was expecting to see a spherical, directionally-twisted-tooth star washer under the nut.
Not really critical, but the right washer would tend to lessen any chance for loosening, which is good since the nut is less easily accessible once the cable gets strung, so the nut tightness might escape routine tightening checks.

I am confused. The nut pictured looks like a 2037. There isn't a washer shown between 2037 and 2033. Not critical.

Yeah I thought it looked like a washer for the bar clamp nut, but I don’t have experience with that earlier type brake lever.

Anyway, I managed to drill out another washer so now both levers have them, right or not.

Your mystery washer is not part 2038. Those are plastic bushings that go between the lever (2032) and lever body (2031).
You can check out Campagnolo parts catalogues going back to 1968 here (www.disraeligears.co.uk) and none of them show your mystery washer.

due route,
That washer was a conical washer that worked like a lock washer for the brake to handlebar clamp. I just went to the campy small parts drawer and pulled one out to check. The later variants had a series of ridges that look like a miniature pinion ring that were supposed to work as a lock washer as well.
The nylon washer that goes between the lever and the lever body is a special ledge washer that is no longer available through Campy. I had a company on the east coast create them for me, but I had to buy 500 quantity lots. I currently have them available to those who need them and the cost is $3 each. It takes two per lever and 4 for both levers. The cost for a pair of lever is $12 (but it will save the levers for years to come). If you have found a replacement washer good on ya. Smiles, MH

Thanks for the replies.
I should have been more clear in my original post. The washer in question is the one for the handlebar clamp. I could swear that the one I still have was original, but it doesn’t match MH’s description. It’s just a flat washer. I have never had an issue with the levers loosening, and frankly this bike doesn’t see many miles these days.
Good to know where to find those nylon bushings; thanks for posting that.

If you look at the cross section of the nut, it is not typical. It has a washer like feature. It can only be used in one way with a socket.
My suspicion is that it was designed that way to avoid a washer due to the difficulty in getting a washer and nut into the deep recess to mounting threads.
