Sm102 ink fountain roller problem

Sm102
Model 1990
I have problem with ink fountain roller
The ink fountain roller value is hesitant (not constant ) and the cylinder move fast
I need to the problem from potentiometer or ssk or motor
And how to adjust new potentiometer
I need, a confirm for motor in picture is ink fountain roller or not

 

Going by your picture the stroke is set at 18 and the physical setting on the gear box appears to be 18 . Check the gears on the top of the gearbox.

As you can see the one gear is made of plastic meashed with a smaller metal gear shaft. sometimes they break causing the motor to max out (no control) .

Im not a maintenance man but if the gears (on top) are not broken the motor is probably shot. Sometimes the stroke will creep on you while you run. Console says one setting, physical setting says otherwise. That could be a pot also.....usually the motor is shot or on its way.

 

If I properly understand you, it is common for the numbers to fluctuate caused by a failed potentiometer. Replacement is straight forward, calibration is done by manually turning new potentiometer to readout "2" on the CPC display, after you've manually turned sweep mechanism down to lowest point.

But, I wonder about your statement "hesitant, not constant". If ink fountain roller is hesitant, not constant (consistent), this would be a mechanical issue at the over-running clutch.

It is the motor for adjustment of how much the ink fountain roller turns.

Didn't know you were speaking of the motor at bottom of photo. Motor and pot for sweep control at top of photo, to the right of sweep adjusting mechanism.
