  • Update on Gremlins

    Posted early in general problems with flaky machines. Update: Lane 2 was repaired by the HM and he didn't elaborate on what was wrong or how it was repaired. I have the machines down to just lane 45 jamming about once per night everytime right at the end of leagues. Works fine the whole night and right within the last couple frames it will pile up. Clutch was rebuilt. After watching it a bit I noticed that pins would stall at the trip lever. Sometimes sit until the next pin bumped them over. I tried a looser spring on the trip lever, still no luck. Ears on trip arm and clutch were fine. I figured it out later after I got pissed and oiled everything from the trip lever back to the clutch. Took it about 6 pins to work in and I had no trouble the rest of the night. We had high school team come in before leagues so it did it's thing last frame of last game and I had another league to get it ready for.

    When you rebuilt the clutch, did you replace the inner plate (with the stop) and the trip blades? Even a little wear can cause tripping problems because of to much friction.

    If the fingers actuate smoothly by hand, then you might need a new belt. This time of the year (friggin cold) is one of the best times to determine the condition of its gripping powers. Hold the pin at the base of the fingers…It should grip and trip.

      I had noticed that the clutch would do it's routine fine...if I lifted the trip arm, it would advance perfectly, drop into place for next pin. My theorizing was that the machine would run fine for almost 3 league games, and then act up. I just never stayed around and ran it much at the end of the night. I figured something must be binding up 'heat-wise' After eliminating the clutch as working fine, and trying the trip lever spring loose and tight. Also playing with clutch tension. That's when I lubricated the trip lever pivot, the trip arm bushings and everything else in between. There is no scheduled PM oiling or anything at this place. Over the next week or so I'll be oiling all the other machines I guess...or should I bring it up with the HM?
