I got my first little mill that i finely got power to, it's a Cincinnati model # 467-14M1 - Serial # 2J34U5M-2 with a parts diagram MMA-63M-420357 From 6/5/1963, it was updated to it's current state in 1978 with the Bridgeport head and accessories and more, then shortly after that it was used very little as the company went to cnc machines.
Once under power it tried to power the table right and left and it moved a short distance no more. And it does not power any other direction. Reading some listings on here I saw a way to check pump pressure on the knee with a bypass line but had no flow ( oil reservoir full - middle port).
Next I saw it was recommended to drain and clean the reservoir, when I removed the bottom plate a 4" heavy spring fell out with one broken end. The parts listing I have is close to this but not the same. I believe it to be from the rapid traverse lever that I now noticed it flops down and not to the middle position.
Something else I saw looking over the diagrams I have that it showed a pressure switch of some type witch I think is on the lower right front of the knee, it has an relay / contact their. I saw only 2 of 3 wire hooked up and it does not move / engage when turned on.
Question 1 - will the broken spring cause no pressure?
Question 2 - do I need to drop the knee transmission to replace the spring?
Question 3 - should I Pull the pump housing off the left side of the knee?
Question 4 - is the pressure switch wiring right?
With this being my first Cincinnati mill I am learning a lot about this unite, but know I also have a lot to learn and any help would be greatly appreciated, I get time to work on it now and then but would like to bring it back to full usage as soon as I can.
Thanks in advance for any advice / help
