Received the new rebuildable part and notice that the tool included doesnt fit inside the springs. It doesnt even fit inside the channels of the rebuildable part. What is the inside diameter of the springs to see if I have one that fits.
I received mine today as well, (thanks Jesse, the hand written note was a nice touch) and the brass rod seems to do nothing in particular. As a work around I found a drill bit in my extensive misc. collection that would fit snug in the channels to assemble the unit. I disassembled everything for an ultrasound cleaning prior to use.
According to one of Imeos video the brass axis is for adjusting the housing liquid channel with the springomize during assembling, and not for the spring.
