  • bang my head(pin) on the fault line

    Having an issue on a lane where on respot cycle the sweep runs after first gaurd too quickly and hits the headpin out of the fingers, knocking it down then out up the lane as the sweep comes back to 2nd gaurd. can this be rectified by rotating the sweep cams? I think towards the front of the machine or should the gaps be adjusted on the levers?

    Turn TA2 in and it will start the sweep back sooner and it won't interlocck.

        Check to make sure the sweep is not over drifting or stopping too late when it goes down to guard. You can adjust the SB cam to get it to stop sooner when it goes to guard or adjust the TA2 to make the sweeep start to run later. Carefull you dont adjust them too much or that will cause alot of timing issues.
        Turn the SB cam lever inwards
        or turn the TA2 outwards
        The SB stops the sweep at guard and the TA2 starts the sweeps run through

          First of all make sure your head pin respot cell 2" gap is correct. If the headpin is hanging too low while in the respot cell the sweep may knock into the pin. If that's not the problem then you are going to have to delay the sweep from starting. Rotate the entire table cam backwards about 1/8" at a time until problem is resolved.. Readjust TA1 so table stops at 355. Test and readjust as necessary.
          If it cant be fixed with a hammer, use a bowling pin.

            Yes to this and please check the respot cell and sweep coasting first.

              Already did check the respot cell gap and sweep coast; its definitely the cams. I was looking at the sweep cams originally because the measurements on problem lane are different than the working ones next door. will play with the table one today and see if I get anywhere.

                Yes, I'm sorry I read it wrong! watch out if you go too far it will interlock on the way back through about at the head pin.

                  I had a machine one time doing the same thing. The reason that I found was we had just changed from the old tube style sweep bar with the cast aluminum ends to a cheap knock off sweep bar assembly that was really thick and slightly taller than the standard style amf sweep bar. Respot cell adjusted properly, no sweep coast and hitting perfect at first guard and it still hit the head pin. Ended up trimming the sweep bar and everything was fine then.

                    Grit, Sometimes the whole switch cluster comes loose, After adj. make sure the table drive latch is stopping just before the knotch or you will have more issues.

                      This problem always pops up after someone hits the sweep with the ball, and for me its just a matter of readjusting SB.

                        Tightening the sweep crank bolt, or replacing the crank arm/key would stop that.

                          Easy fix, just take the angle grinder and cut a U in the middle of the sweep, wala!

                          I read on here a while back that a not so intelligent tech had actually done that at a centre where one of the guys on this site went to work at.

                            bad description words incoming:

                            After looking at the table cams closely the left 2 which I think are TA1 and TA2 were not close to each other so I moved TA2 out and the problem is solved. The middle one (TA2?) is supposed to be in a smidgeon further than the left one(TA1?) correct?

                              Grit, as long as it works correctly is all that matters. My fingers are not the same on every machine. Each machine is a different beast. Good Job!!
