Campagnolo Ergopower overhaul

[Jonathan Murray]

I have pre carbon fiber Record levers, 9 speed...

My question is this:

This is in regards to the left hand lever.

The flat spring that goes on top of the thumb shifter part connects to
the plastic lever body via the little hook. Does the center of this flat
washer spring go around the 5 mm bolt in the center?

This is the symptom: if I tighten the 5mm allen bolt so it doesn't move,
the thumb shifter doesn't return after you depress it. If I keep the 5mm
allen bolt loose enough for the thumb shifter part to return the spring
rotates and the "hook" in the spring doesn't engage the side of the
lever body.

Is it ok if the flat spring rotates and then isn't making contact with
the lever body?

Anyone know the answer?

thanks.

shift the lever as if into the 'big ring'. put the inside 'hook' of the
flat spring in the notch at the 4 oclock position, then around to the
little notch in the body. Bolts securing the guts were 4mm and now
3mm..not sure about the '5mm'. Something is not installed correctly if
you tighten the bolt on the back and the thumb button won't return.
Something is making the guts 'too tall'.

If it is still gooned up, sent it to me and I'll turn it around same
day.
