    Haas Tool Changer making honking noise at end of tool change

    I have been having an issue on my umbrella style tool changer on my Super Mini Mill where there is a slight delay at the end of the tool change. I just changed my air solenoid valve ( labeled "A" on my photo )

    That seems to help, but on about every 5th took change there is still a delay.

    I took the cover off the part labled "C" and sprayed some mass air sensor cleaner inside that, and now I'm getting a honking noise at the end of the tool change. ( The best way I could describing his like a goose call )

    I'm running an air dryer on my air lines.

    Any suggestions ?

    One other question.... The Part labeled "B" appears to be an adjustable regulator, I haven't touched that yet, but just wondering if thats something I should look at adjusting?

    I have posted a video on Youtube showing the slight delay, and the honking noise.

    could be the Humphrey valve screwed into the right side of the solenoid valve you have labeled C. the diaphragm inside is mostly likely junk. might check it out.
