  • 8290 XL balls sticking behind the bounce plate

    Hey I got some 8290's where balls are getting stuck behind the bounce plate and in front of the cushion. Any ideas?

    I am thinking something with that plate under the carpet right there. What are your ideas?

    I am trying to picture this....the cushon being mostly behind, and above the bounceplate. are you talking about partaly under the cushon in the corner?? If so, check your shock. If it is weak, it can contribute to this. Next would be the support weldment and the angle. Might be time for a pit overhaul.

      Could be a broken bounce plate, vibration damper, pit support bracket, cushion shock could be bad as Jim suggests, or the spring collar has slipped dowm, the spring lenght should be 6-1/2"
      Please.....follow the instructions!!

        I guess from what I was told is that it is every odd lane. So I am thinking that is something common. I do not think this is a huge problem I am just attempting to shorten my learning curve here at Bowltech. I will start at the shock length.

        The ball stays right in front of the cushion. This house uses more oil that is drilled in middle east in a month every time they run their machine.

        Thanks for the input. Thanks for posting John. It was nice talking to you the other day, very helpful. Sorry I had to go all the sudden. Those darn other jobs! [img]/content/btubb/images/%%GRAEMLIN_URL%%/burningmad.gif[/img]

          Could it be that the cushion plank is driven back and hanging up on the shaft of the paddle drive assembly. This would be on all odd machines. Just a thought. Paul

            Check the condition of your facing... dirty and sticky facings will casue this. If you have rubber rivets, and they are exposed on the bottom row, the oil and cleaner cause them to become tacky. A smear of lane oil will relieve this for a short time, but is in no means a perminant solution. Let us know what you find.

              If these are older machines check the rear bounce plate for a round indentation.this holds the ball and the quick fix is a rubber pad approx. 1/2 to 3/4" behind the cushion facia at the end two rivets,above each other , not across, at the ball door side helps to push the ball towards the ball door.
