Rowe AMI Music Miracle 3 Model Number 1100 Help

[RyanA]

Hello

I am new to the jukebox game and recently acquired the above jukebox. When I received the jukebox, one of the gears in the transfer motor assembly was stripped which prevented proper operation of the jukebox. I was able to manually rotate the transfer motor gears to get passed the stripped locations and, while still manually rotating, the gripper arm would pick up the record, drop it on the turn table, the stylus would slide over, the turn table would turn, and music would play. So, it seemed to me that the only issue was the stripped gears on transfer motor.


I acquired a new transfer motor assembly and installed it. However, now I have the below issues:


1. The turn table will not rotate

2. The gripped arm will keep picking up the same record, drop it down, and then pick it right back up over and over


There are some other issues, but I think these are the most glaring for now.


I need to mention that when I was changing the transfer motor, I had to replace one of the cam switches and the black rod on the new transfer motor is shorter than the black rod on the motor that I replaced.


I have a feeling that the issues tie back into either the cam switch I replaced or just the cam switches in general not being opened/closed at the right moments.


I have attached some pictures below and I have consulted the manual but I need additional guidance.


I did read the FAQs and “Hi Newbies” so hopefully I did not violate anything.

I appreciate any and all help!! Thanks!

Hi Ryan,
I see nothing that can "actuate" the cam switches -- can't recall-- add a photo of the old assembly ? Ron Rich

I removed the plastic cam from the pictures for clarity.  I will add it in and retake the pictures during lunch and include a photo of the old assembly.

Hi Ryan,
OK-- that's what confuzz-ed my simple mind ! If that black rod is long enough to move the cam, in a fashion that will actuate the switches, I see no reason to worry about it's "length" ? Ron Rich

Yeah I do not think the length is the issue as the cam fits on there and rotates just fine, just wanted to see if others agreed. When looking in the manual, it lays out what each cam switch does, but there is not a layout showing which cam switch is which.  I tried to manually actuate the switches to try and see if I can locate the switch that would rotate the turn table, but I could not.  Do you think that I am onto something in thinking that one of these switches is the reason or am I way off base?

Hi Ryan,
Have you looked at the cam switch adjustment procedure on page 5-5 of the manual?

Norman,

I know that I have read that section but I have not given it a try yet. I believe it talks about basically positioning the switches I think 1/8'' above the step on the plastic cam.  When I put the new switch in, I thought it went right back into the original spot but maybe with the whole new motor assembly, all the switches need to be checked. 

[jukenorman]

Hi Ryan,
It also states in the manual that if a cam switch is replaced, the cam and switch adjustment procedure should be carried out, so I really think that would be a good place to begin?

Norman.

[RyanA]

Norman,

I must have missed that part in the manual but I agree.  I really think the new switch I put in is off by a hair, but thats just my gut feeling right now.  I hope to report back tomorrow as I am having a few suds after work today.  Cheers!! 

Below are some pictures of the cam and switch setup after I followed the cam adjustment procedure but I did not check all the switches yet.

Just wanted to give an update that the switch that I replaced was a hair too close to the plastic cam which was causing the switch to be activated when it should have been inactivated.  So, the problem of the turntable not spinning has been fixed.  On to the next issues haha

Hello! Back again with another issue I hope to have some help in resolving. I have some pics below for reference.

When a new selection is picked, everything seems to be working correctly.  From what I can tell, the transfer motor rotates which causes the crank pins (long and short) on the transfer motor to also rotate.  It appears to me that those crank pins are supposed to "catch" on the transfer link which then rotates the sector gear and grabs the record, drops it down, and moves the stylus over and plays (reverse order occurs when song is done).

However, I do not think that the crank pins are "catching" the transfer link.  Sometimes it will drop the record down but the segment gear is not all the way up and the stylus will not move over.  Other times, everything rotates in the transfer motor assembly but the crank pins do not "catch" and the gripper arm never moves at all.  Do I need a new transfer link or is something else going on here?  If I manually move the segment gear all the way up or down, the system will function properly 

I hope I explained this well.  Let me know.

Hi Ryan,
I would suggest you sit there and observe as it operates-- note the differences between the correct, and non correct operation, and determine what the cause is-- ? Ron Rich

[Ron Rich]

Or-- make a video of what's happening ?? Ron Rich

[RyanA]

Ron

Thanks for the reply.  I can try and take a video but might be kind of hard. It seems to me that the crank pins sometimes catch on the outer edges of the transfer link which will partially cause the segment gear to rotate.  However, when it runs like that, the transfer link can slip off or the crank pins miss completely and just push the transfer link without rotating it.  I am assuming the crank pins are supposed to be in the slotted/cutout portion of the transfer link?  I just changed the transfer motor so maybe I just need to reset it so the crank pins are in the slotted/cutout portion of the transfer link?

Hi Ryan,
I agree that your problem is probably related to the changing of the transfer motor. There are a number of adjustments relating to the transfer cycle at the beginning of section 5 of the manual that I think you should check. I take it that you know that you can drive the transfer cycle manually using a 5/32 Allen Key?
