Problem with Campag Shifter

Dear Campag experts, my Campag Veloce left (front) shifter seized up about a month ago, such that it would neither shift up nor down. Some very gentle forcing (about 50% harder than you would normally press to shift) freed it up again, and it returned to working normally. Over the last couple of days, while continuing to work normally, it has started to make a high-pitched ping with each ratchet in either direction. I imagine that one of the springs has snapped, or become dislodged from its normal position.

I have only ever owned this one Campag shifter, and have never stripped it down, having bought it NOS in '06. It was said to be '98, but I can't verify this. I attach a picture of a similar set of shifters below, identical in all aspects except that mine only has Veloce stamped on the lever rather than horizontally in white on black above the lever.

I'm certain that I need to strip it down, but I don't know what I'll be looking for. Is there a part or set of parts that I should order in advance?

You need a rebuild.

'Could' be 1998, last year of pointy top ERGO, along with rounded shape of Record and Chorus. Innards are different than the video shows. Not that hard to OVH but re-assembly can be a challenge with a big, flat spring at the very back of the shifter.
Send t to me for a one day turn around.

The timing reminds me of my years running the East Coast Service Center for Campagnolo. after a few years I noticed certain seasonal problems, one of which I called the August shift lever blues.

Every August there'd be a surge in jammed ergo levers, typically caused by sweat wicking into the thumb levers and rusting the pivot. I'm speaking of the little riveted pivot where the thumb pad joins the section entering the lever body. When you press the thumb pad, this articulates and engages the cam, but if rusted the friction is too much for the spring to lift the pad and dis-engage the cam after shifting, and the lever jams with the next shift.

Fortunately, this can often be fixed without dis-assembling the lever.

Locate and examine the pivot. With the bike right side up, depress the thumb pad slightly then release. the pad should crisply snap back to place. If not wick in a drop of penetrating oil (mix machine oil and mineral spirits or naphtha 1:4) and work the pad until it's 100% free and springs back instantly when released. Prevent future problems by oiling the pivots on both levers from time to time.

Good suggestion, but I'm in the southern hemisphere - not too much sweat running down my wrist in chilly August!
I've had a look and I don't seem to have any rust on the shifter.

Australians - where do you get your Ergopower shifter parts? The Internet doesn't seem to offer much (or anything, really).
