Conti lever rebuild question

Conti lever rebuild question

Mo - thanks for the baby best wishes. Although "Doppio" would gain him respect in *some* circles, we opted against it Instead, his name is Noah. I'll pull the piston out soon and measure it. But regarding the spring forces, using the data Mo posted, if you take the gap of

Conti lever rebuild question

timo - here's a real close up view of the piston 4-bar linkage with a metric scale. I had to reduce the photo size considerably to get it on the website, so if it's too crude to get the measurements you want let me know and I can email the original photos to you. Here's the piston

Conti lever rebuild question

Thanks for the generous props folks - I feel lucky to have been in the right place at the right time, and to have been able to strike a deal with PetePO. My wife is very understaning As for the spring dimensions, I didn't take any measurements but I certainly will when I get a chance

Conti lever rebuild question

Conti lever rebuild question
