  • Front Roller

    I have a machine that the front roller keeps popping of the front roller bracket on the 7pin side of the machine. I put it back in then it will run for 4 or 5 days then it will pop loose again. Looking for any ideas as to what the problem could be to solve the problem.

    Re: Front Roller

    i would assume the prob is a pin idling "belly up" between bounce plates and front roller. then someone throws a ball down that gutter which pops it out. . . particularly if the carpet is ragged or short on that side/lane

        You could make a bracket & mount it so a pin head cant enter.

        Replace the carpet with a new good one.

        If the carpet is riding all the way to one side, Check the roller & Roller brackets.

          The t-bar under the carpet from side frame to to frame may be loose. This allows the bearing flange to move from behind the bearing and snap forward when a ball is thrown down the gutter. Also have seen this happen if one end of the roller is put on in reverse, not allowing the roller to swing at all.

            Check the brackets and mounts on the rollers... as long as they're OK, sometimes it's just that the backend has a lot of clearance between the front roller and the tailplank, which allows pins to sit there and roll. If you can't move the backend (and you usually can't without moving the whole row because the ball exits and backends won't line up)

            Dig out an old cushion rubber, cut a block of it that has at least 2 rivet holes in it. Place it against the tailplank at the back of (and below)the flat gutter and use wood screws / lag bolts and washers to attach it there. Locate the bolts and washers inside the rivet holes, so they're recessed into the rubber and cause dings/scratches in pins or balls.

            If you don't have a cushion rubber to cut up, a piece of 1x4 soft pine with the corners blunted and some countersink screws in it will work well, too.

              Chuck, nail a piece of carpet to the Tailplank, so it sits on top of carpet and covers the gap. This may cause a pin to idle there occasionally but better than the roller popping out. Will do until fixed properly.

              If it's not a pin getting behind, causing the problem( really a short carpet problem), than it could be the front roller put together wrong,i.e; one end on upside down.

                I have that problem too. Have an excessive gap. What I ended up doing is to cut a piece of garden hose and screw the ends to the tail plank as a filler.Problem cured.

                  Yep, Frank - we do the same thing (fix a piece of carpet to the back of the flat gutters to cover the hole between roller and tailplank). Maybe it's an Aussie thing ;-)

                    <font size="2" face="Verdana, Helvetica, sans-serif">Not just an Aussie thing. We don't have a problem with excessive gaps but when a carpet is riding over and shot and we can't get into the pit immediately due to other things we use an old piece of carpet or dist belt to keep pins out. It helps a TON until you can go ahead and pull the pit
                    All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

                      <font size="2" face="Verdana, Helvetica, sans-serif">Heck of a good idea ya got there.

                      I've seen loops of carpet placed on the tailplank, also... you fold the carpet so the loop sticks up, and the free ends face down... then you screw it to the tailplank so the screws are below where pins or balls can hit them. One drawback, you have to pull the pit (or at least the front roller) to put it in.

                        there is a possibility that the jack key is sticking through into the pinspotter and stopping the roller housing pulling forward.If this has just started happening, is it on an even lane. Perhaps the ball idler bracket is broken off and the roller pops with the balls entering the ball door as the carpet is pushed down.
