    Re: shotgun

    it sounds like you need to adjust the trigger link. adjustment#5 in the service manual.

    Conditioner: Pantene Pro-V Brunette Expressions with Color Enhancer
    Cleaner: Fabuloso Spring Fresh with Bleach Alternative
    Cloth: ShamWow!
    Machine: Johnny 5

      Hey laze
      First check and make sure your gearbox clutch is adjusted right and the machine is stopping at ZERO.
      Then with the machine at ZERO check the gap between the C lever and the rake cross member shaft.
      There should only be a slight gap, the manual lists the exact measurement.
      You loosen the shotgun set screw and insert a punch into the holes of the shotgun around where the spring is.
      By threading or unthreading the shotgun you can get the proper gap.
      Hope this helps.
      Remember to go FULL turns because the shaft has a groove in it for the set screw to lock down on.

        If you are gonna adjust the shotgun in that way dont for get to check the rake board height if its too low it will drag the flat gutters and catch on the tail plank. Then you'll have to change the rake crank rod, after it bends

            Re: shotgun

            Problem is, it could be anywhere from the pit cushion linkages on up. May sound stupid, but has anyone changed the:

            Pit cushion linkage
            Tri-plate bushings
            Pivot lever

            A bushing left out of any of the above during reassembly could give you a gap too big to adjust out of the system.

            Also, be sure your Linkages from the rabbit ears to the tri-plate and tri-plate to cushion are adjusted properly, and check the cushion linkage for smooth operation

              Sounds like kevin has the answer on this one I would look at the cushion linkage and bushings. If the follower bushings are missing that would cause a large gap! Best of luck to you.

              Treat everyday like it could be your last day!

                Measure your gap at the "c" lever part or the rabbit ears and make sure it is 1/4 inch from the sweep shaft...if it is wide it cause the problem you are describing.If it is wide:check to see if pinsetter is stopping at 0 as mentioned earlier,then check your shotgun length (this makes your 1/4 inch)after adjusting shotgun check rake shock adjustment(1/16 inch at 90 degrees)then double check your rake board heighth at lane as it sweeps.

                Keep us posted,

                  I hate before I have to go to the book..most of the time I got machine next to it and check the adjustments and try to make it the same...then I go to the book while the machine is running ok and see how to adjust a new machine

                    Re: shotgun

                    Jordan Your rake cam may of slipped from the proper dwell this will throw off the cushion linkage and make it hard to get proper ajustments.One good sign the rake cam is outta wack is that you can lift the pitcushion up high above the normal triggering space.And it wont trigger by the trip lever unless you pull really hard and force it.Check the other ajustments too the Clever and proper rake board and rake shock ajustments....Good Luck
