Overhauling the gear selector assembly is ideal when as many of the wear and damage prone parts as possible are replaced with new. This will attain the best results, as interfacing used parts with new may lead to premature wear of the new parts, and a less smooth, more recalcitrant gear change. Check the fulcrums and pivot points on the gear change assembly itself at the same time?
