Hi, to all those who know, I have a problem that my hydropunch clatters. Now I have the intention to change the twelve and I wanted to ask if the cracks among you have a few explosions for the block. Furthermore, my gearbox will just die in CAC if someone could give me drawings and tips as I can overtake the thing and what I should pay special attention to, that would be so cool! For your help I would be very grateful!!
