>The click occurs when the jack snaps forward. The jack center pin > resistance seems within acceptable limits, the spring works properly. > The non-clicking jacks rotate smoothly throughout key stroke. > Any brilliant ideas on how to solve this? Greetings, Check to see if the end of the spring is digging into the jack. The spring may be too long, or it may have been bent. Also, is there more spring than is necessary? Those hammers shouldn't jump when released from check! Regards, Ed Foote RPT
