we are working on reduction gear boxes and on 1 of them we have small pin hole leaks near heat sink gussets . I was wondering if anyone had ever tried used a slight vacuum to draw a sealant into a defective pin holed weld or crack . If so what type of sealant did you use. These places are difficult to get into to repair and time is a issue.
