  • J2 Issue

    Periodically, one of my machines will get a J2 code. When the table is down, it gets stuck not being able to come back up. While this happens, there's a loud shaking sound as if a machine gun was going off. Once in a while this happens. Any suggestions.

    I recently seen a pinsetter make that loud noise. Turned out the Table Gear, Sweep Gear and Pulley Drive Assembly was loose and the noise was the chain skipping on the gear.


    • #3 addition to what rgarcia said, the motor could be skipping due to a bad tension spring or bad belt or pulley coming off.

        to what rgarcia and loadtoad have said it could be one of the centre aligning bearings gone or ceasing up

          It might be a rare thing but we just had this issue going on for a month off and on, then a week ago we had the big plastic gear behind the table motor pulley break, since we changed it we haven't had the issue again. Our theory is that it was likely cracked that whole time and then finally broke. I would check the condition of that just in case.

            With the machine I saw the original problem was what Bking4242 posted. This issue was at my sister center and when I looked it over they had replaced that pulley but the housing it is attached to wasn't installed correctly. After tightening and replacing the four bolts, the issue was solved.
