The majority of the time the problem is in the indication, especially if the machine has not been used for a long period of time. The printer usually does not give problems unless something gets jammed inside, like a coin, pencil, or other foreign object.

Sorry for the dumb question, but what do you mean by indication? Are the indicators the drums up top that show the price and clerk?

The numbers that show in the front & back windows are reffered to as indicators. They indicate the amount rang. On the early machines where the numbers pop up when you depress a key are sometimes called "Flags" due to the fact that they are printed on a "Flag" but they still indicate the amount of the sale. I also refer to the red flash that comes up when you press a key or ring a sale on the crank machines. This was done because operators could ring up a sale & get the previous sale & the new sale up at the same time & confuse the customers so NCR put on the red flash that hides the transision from one sale to the next.

Yes, these should be able to wiggle back and forth without the one next to it moving with it. If they are tight or they move together that may be your problem

Thanks everyone for all the information. I think I took a bit of everyone's advice and I was able to finally get the register unstuck. (Thanks Dick for the phone call) That being said, it is really hard to get the register to crank to the point where I think something is going to snap. I am looking for advice on what to use to lubricate these 400 series registers. What brands of oil, aerosol vs. squeeze bottle, etc.?

Also, if anyone has any tips specifically for these registers on what to look out for when lubricating them, that would be greatly appreciated as well.

Thanks again!

Haha, good point. It was a mixture of a few things. First I sprayed it down with degreaser to break up all of the old lubricant that was in there. Then sprayed everything down with WD-40. At that point things started to loosen up. What really got it unstuck was while I held pressure on the handle, I tried to move the indicator wheels with my hands. Even right now, there is where I feel the majority of the friction is coming from. But to answer your question, YES it was just forcing it through its cycle. :)

Now as for the best way to free it up the rest of the way and keep it running smooth, any ideas on what to use?

I use Liquid Wrench penetrating oil in yellow can. They also make more regular oils in green & blue cans. Others use Kano (Sili Kroil ) penetrating oil. Better than WD-40 but not as good as Liquid Wrench. I use Tri-flow as a final oiling & some NCR 801 grease. I recently found a graphite penetrating oil from Slip Pate. Better than both but is real messy. WWW.slipplate.com . It sounds like the indicator wheels are frozen to the center shaft. Pack around the wheels & spay on both side. Work each wheel till it is loose. Also type wheels & add segments can make it crank hard. Test by pressing 9191's & operate then 1919 & operate.
