  • Worm shaft nuts

    Real quick. Are the two lock nuts at the end of the worm shaft reverse threaded? My gear box has seemed to lock up and I heard loosening them a bit might help

      The nuts are standard thread; however, loosening them may throw your gearbox clutch out of adjustment. Adjustment #15 on page 77 of the Model A pinsetter manual has instructions.

      Whenever the gearbox clutch is readjusted, the clutch cam follower and clutch reset lever will also require readjusting.

        If your gearbox is locked up, loosening the nuts won't unlock (unbind) it. First you will need to reverse the gearbox using these nuts (if pulling the belts in reverse doesn't work). Engage the clutch and use a 1-1/8 wrench and turn the outside (rear) nut in the direction of the arrow on the gearbox (just like clearing a deck jam) until the gearbox becomes unjammed. Check oil level and add if needed and go ahead and loosen the nuts slightly at this point. Run the gearbox back to zero and go through the complete gearbox clutch adjustment. If oil level is OK, be sure to look for what jammed the gearbox. (Loose deck/spotting finger bolts etc...)
