Seeburg M100C Reversing Issue

I am trying to figure out why my Mechanism will try to jump off the track at the end of the catalog and not reverse back to A or B side of the record. I went ahead and adjusted the reversing switch as per manual, still no luck. I have made all clutch adjustments as well.
What I notice is if I hold up on the "clutch shifting lever" from the front of the mechansim it will not jump, but instead work as it should. From looking at this lever there are a few springs, holding it up in the front and down in the back, are these springs worn out or is there an adjustment I missed?
Happy New Year,

Bob, I have never seen this happen --except where either the motor or the reversing switch has been replaced and miswired (mea culpa).

With the mech scanning somewhere near the center of the rails, if you place your finger ahead of the reversing switch paddle, when it touches your finger does it flip to the opposite direction and the motor reverse instantly?

If the paddle looks like this \ the mech should be going from left to right. If not, then either the motor or the switch has been wired incorrectly

If it acts as above, the only other thing I can think of is the reversing tabs are too far toward the ends. This is a straight-forward problem.

Alright I just tried to flip the reversing paddle while the mechanism was midway through the scan and the motor did not reverse direction-it just continued on like nothing happened.

Bob,
Is the mech hitting the rubber bumper prior to the reversing switch being snapped ? Are the "0" contacts working correctly ?
Are the "inverted "v's" on the rev switch set correctly? Is this happening on both, or just one end ? ( Never saw "springs" causing this problem ?) Ron Rich

The mechanism is not hitting the rubber bump stops

Then you do not have the reversing switch "toggle" correctly adjusted--see the service manual--

I have reversing switch 1 and reversing switch 2 adjustments in my manual, I have done both adjustments. I do not see an adjustment that refers to "toggle." Do you think my rubber bumpstops are just worn out?
Thanks for your help guys

Bob, forget the bumpers for a while, they are a minor element here and don not have a role in reversing the mech.. Their main purpose is to keep the mech from coasting too far and placing stress on the reversing switch. The mechanism should reverse when the paddle is flipped anywhere along it's travel when flipped..

When the switch paddle is flipped toward the right -it should stay in that position and the mechanism should travel to the right. Flip it to the left and the same conditions should exist going in the opposite direction.

Take a look at this video: https://www.youtube.com/watch?v=uA_bHbLw2LM Toward the end the view of the front shows the reversing sw paddle flipping..

BTW: you mentioned that it just keeps going in the same direction when you manually flip the switch. How then do you get it back the other way?

Is there any way to post/send a vid of the action? This is one of those blindingly simple things that I think is getting fouled communication.

Rob

i use the service switch to slow it down at the end of the catalog, and it goes to the opposing side without a problem. Lets see if I can make a vid?
Bob

Ok Here is the vid-notice when i apply light upward pressure to the clutch shifting lever
thanks guys

Bob,
The "toggle"I am referring to, are the metal tabs that actually "flip" the switch. Th manual does not cover this on the 100 select mechs. What I do, is first reverse the screws holding them, so they go from the top down. Then I loosen the two screws enough so I can slide the whole thing. Manually turn the motor coupler till the rubber bumper hits, then back it off about 1/4 inch from the bumper.This is the point that the toggle MUST hit, and have fliped, the lever, on the reversing switch.
Did you check the "0" contacts ?? If good, and the motor will NOT change direction, when in scan mode, your motor run cap is bad--
CAUTION NOTE, for those of you with later mechanisms, that have the newer type read, out contacts---
NEVER flip the reversing switch, at any place other the an end of the record rack---you ruin a contact if you do so--

Bob,
Just watched the vid--three things I see wrong--
1. The three "9/16 hold down nuts" are tight--run them all the way up the studs till they jam !
2. either the "O" contacts are not making, or-you have the new motor cap installed incorrectly
3. ( which I doubt)You have a "bad" motor
Do NOT put pressure there, as you are binding the whole clutch/drive train assembly--
Ron Rich

Once again Rich-You the Man-I just switched the 1.0 contact and the "C" contact and all is well
Thanks All for your help,
Bob

Glad you found it !
