Mills QT springs

Postby apiscione » Fri Mar 28, 2025 10:59 am

I have a Mills QT machine and some of the springs got disconnected on one end. I don’t know where to connect them. Is there a diagram that shows spring connections?

QTs are a bit sensitive to spring size (diameter, length, and strength) so a few pics of your mech would help. Left side, front, right side, and back. There is a repair manual for the QT but it is out of print.

I’m a novice on this forum website and I don’t know how to attach pics. Can you help me? I can email you pics.

I'll send a few pics tomorrow and you can use them for comparison.

Here are some general pics of the QT mechanism. It is quite important that all springs on a QT are correct with proper spring size and strength. If not, that can severely impact the ability of the slot to cycle and pay out properly.

The pics were very helpful. Looking at the springs, the ones on my machine matched. However, there’s a space of about an inch to the right of the reels. Looking into that space, there are 2 springs hanging with the lower end not attached to anything. One of them seems to be attached to the bar that is about 2-3 inches above the reels.
