Hamilton quarter hopper not ejecting coins - SOLVED!
First time working on a change machine, so I thought I would ask some questions before I tear anything apart
This is a Hamilton bill changer from 1994, Model EV-H. I downloaded the manual and it has been very helpful so far.
After going thru some error codes and finding a bad ground wire on the back of the hopper, I have everything working. Bill is accepted and verified, then the coin hopper gets a signal and starts spinning. The issue is, it won't eject the quarters.
Looking closely, I see there is a pin on the bottom of the spinning tray that is supposed to push the quarter up into the eject slot. It seems like it's not quite high enough, so the coin doesn't catch and the mechanism keeps spinning until it times out.
I noticed there is a mini leaf spring under that pin which pushes it up towards the hopper. With some extra pressure, it lifts a little higher and coins eject as expected.
My questions:
A: Do I need to track down a new part for this?...or...
B: Try to bend the leaf spring thingy to get it to push up hight?
C: Try to adjust the height of the spinning tray by loosening the allen screw?
D: Maybe a combination of B and C?
I tried to highlight the sections I'm referring to in the pictures. Thanks in advance for any suggestions!
