Brass pin punch onto the ball and a sharp tap with a hammer works for me. +1 … always seems to be the preferred method. |

87 forum posts | I've used that technique on hydraulic systems running up to 720bar. Now here's a thing. I wonder if such an arrangement would be more likely to leak with more pressure, or less pressure?! Anyone care to hazard a guess? |
