  • SS Chassis diet

    Well I have an old beater chassis I'm looking at getting going and using for a test bed for removal of unneeded parts. Especially when so many were removed for me so long ago! I'm running Qubica scoring and probably will be adding expanders and round c23 plugs. Any photos would be appreciated.

    So far got Caps 1-3 removed that I did and Aux board, spider relay, and contractors removed already.

    This diode and heatsink was removed. Needed or not? I have a spare I can use.

    I heard KX relay causes problems, so I will probably remove that.
    Chewing through the old post removing stuff from SS chassis so looking for info and the diodes and the rest of the fun.

    I'm pretty sure that has to be in there.

      Removing heatsink assy removes movisters across the sweep and table contactors. Not a good idea. They route stray spikes around the coils.

        The only thing I've removed from a chassis is the AUX board when converting from 5-Board to Single Board Omega-Tek on an Elco Style..

          I dont remove any thing from that heat sink assy.The small wires make connection to sweep & table coils and C2A.Also the power diodes are for mask lights.I do remove the auxilary board.In some cases I convert elco chassis to C23 by drillining a 1 & 5/8" hole with a hole saw where the board use to be and mount a C23 receptacle there and wiring 7 wires to the mother board .2 wires to MP 2&28 for mask switch then wires to MP 24 th 29 for power and ball /foul and X light.I also install a led lamp for 2 nd ball light As newer masking units do not have pindication and its hard to see ball lights from the back.Actual cost of parts to convert to C23 both in chassis & mask plug is only about $20.00 per machine Also from what I understand they dont make elco terminal any more.I also run a aditional ground wire from the ground terminal stip to a screw holding the mother board as I find many of the terminal strips rivets are not tight and you can lose ground.

          4:1 Timing off..

          *sigh* Hello friends..

          I had a 4:1 go bad and I've never seen or done one before. Trying to search the depths of the forums, YouTube videos, it didn't seem too bad....

          Adapting the Bluffton end cap & terminal board kit to Franklin BE (and FE) motors.

          Left a rant about this in the bowling forum…

          I’ve already repaired a a number of Franklin FE motors using the Bluffton-style end cap and terminal board kit (090-004-582)....

          At what thickness do you replace the clutch face.
          Is there a minimum dimension from the clutch face to the rivet.

          Is anyone running the solderless relays on the accelerators? How do you like them? What brand? How difficult to convert was it? Would love the feed back as I'm about to switch...
