AM Multilith 1650 won't run....

[HopDevil]

Hi All

I have a 1987 AM Multilith 1650 1/c duplicator.
I am unable to get the press to start. I think the culprit is
the safety shut off on top of the press, the red push button.
If I giggle the knob I am able to hear the switch kick on and off.
I am able to get the exhaust fan to spin on the gear side but the press
won't turn. Ive checked fuses and other micro switches and all seem to be ok. The press ran before I trailered it home.

Ive run these presses before but a few years ago. I ran a 1250, old style, in high school but was less electrical than the 1650. I wouldn't mine eliminating all of the safety features if there was a way to do it. Is there any way to bypass that safety switch?

Any other ideas would be appreciated. Im itching to get it running. Ive been sitting behind a desk for 8 years estimating printing. I want to print something!

Thank you
Hop

First unplug the machine from the power source. You can then remove the control panel box with the on/off switch and speed control. Unplug the the box from the harness. Remove the control box rear back plate screws and see if any wire or connector broke. Good chance something broke or came loose on the ride home. The saftey switch on top is a stop button and forward/reverse incher. Be sure the stop button isn't depressed and locked down. This will disable the press. Yes you can bypass the safety switches but be aware of OSHA and insurance inspectors. You can either remove the cam on the covers that depress each swtich ex, del cover, roller cover etc.... or unplug the switch itself. Some have a bypass connection on the switch for maint/repair where you can change connections and bypass the switch. I'll double check at work tomorrow if you need to know. Other than that look for loose or broken connections. Those machines can be very problem prone with all the relays, boards and switches. As they get old they break. Expensive and sometimes hard to find. I have some parts from the one I parted. So if you find something broken I might have one. I have part manuals too if you need a number. Now that Multi was consumed by PressTech they'll be you go to source for new parts.

Thanks for the response!
I was able to get it running last night.
Somehow, I over looked an unplugged wire in that main panel box.
It had a inline fuse, which i checked, but might have unplugged it by accident.
I plugged it in and she fired right up. I was happy.
Was happy to see it wasnt a bad board.
What kind of parts do you have left? Interested in selling them?
This is only a hobby for me but could use some extra parts.

Thanks

It's pretty much 2 old multi's parted out minus the side and main frames. Let me know more of what your looking for and we'll work something out.

Ink and water rollers.
The ink rollers are coming clean but not sure if they will take ink. Especially the soft rubber rollers. The ink fountain still had ink in it so it is caked on the fountain roller as well. Its coming off but slowly. Do you have a ink fountain blade? What kind of water system do you have? Mine has a Thistle which works and im fine to start with it. Im not sure if it needs anything else. It probably does but until I start using it, im sure I will find parts that need to be replaced.

Thanks

Solvents like MRC or Rapid one step will loosen and help remove the dried old ink from the ink fountain and fountain roller. Use some putz polmade with a scotch brite pad with the solvent on the fountain roller. You can even wrap a rag on the roller and soak it with solvent and let it sit to help loosen. The ink fountain blade can be removed. Chances are some of the keys are gummed with ink or bent. Also the retaining wire gets bend up or broken. That's there to keep the keys from walking. But it all comes apart. I have 2 types of water system parts. First the old conventional with ratchet and pawl like the ink feed is. And the later multi matic which is the later worm and gear where you increase/decrease with the round knob. I have both water and ink ductor assys. And a few spare ink fountains. Let me know the length and dia of the ink and water rollers you need. If your press is the 12.5 x 17.5 you need the wider rollers. Might have a few new ones I'll have to check. I have a bareback roller system that was the poor mans Kompac. These are just rubber rollers you run bare but ink up with a bead of ink across them when you startup. I have all the little brass idler roller ends and clips. And the small stainless ends and clips for the newer style ink and water ductor rollers. Some parts are interchangeable from way back. And some are not and new style. Boxes of stuff I have here!!! Also places like Printers Parts sell new aftermarket parts if needed. The new ink fountain blades are a file fit meaning you need to file and size the width to your fountain. Some of the newer brass and aluminum parts are junk from overseas. Like everything else you need to pick and choose thru the garbage.

Ive been using V-120 to get the ink off. Its coming off but slowly.
I will try some of those other chemicals if I place an order.
I found ink blades but over $100 for 1.
The model Multi I have is the 1650XE.
My main concern right now is ink and water rollers due to their condition. I would be more interested in any new rollers you have. But used I would consider as well.

Hey HopDevil, how you doing with your Multi 1650XE? I'm a pressman with 40+ years of press experience and I just went to work for a place with a 1650XE. It's a nice machine and I can get pretty good register out of it if I tickle it just right.
