campy ergo overhaul

Does anyone out there know by what mechanism the thumb part of an ergo
power lever is returned? Currently I can't seem to figure out how to get
the thumb part to return after I press it down. It just stays down. If I
losen the 3 mm bolt then it works, but the whole assembly is very
sloppy. I tried using the directions from Zinn's book, but they weren't
precise enough and there are no photos. Better yet can someone recommend
a good ergo power overhaul manual or reference? Does anyone know if ergo
power overhaul is in the park manual?

thanks

Dear Jonathan

Andrew Muzi gives you a good idea of what's involved:

There was an earlier article that I could not find today, and the
author asked about what the cause of a functional problem he described.
I ask because it sounded to me as though the thumb lever spring was at
fault and I am just ondering if that was you and the problem is now
confirmed.?

TIA

Thanks all, I'll give that a shot, on a first glance it looks like my
ergo levers didn't come with some parts they appear to need. On my left
lever I have no bushing where the center of the flat compensation washer
connects. As it never had the part, it's amazing it ever worked.

thanks again.

Agree, Andy has both the official Campy version and a nice write up by
Paul Southworth.

For video, check out Youtube, it has a video on both assembly and
disassembly.

Sure, it's a spring with a 'post' on it.

If ya want, sent it to me and I'll OVH, one day turn around. I'm
suspecting it is not reassembled in the proper order, to cause what you
are seeing.

thanks to everyone's suggestions. I the bushing that haold the center of
the flat compensation washer was installed in the wrong place. It works
perfectly now.
