  • spotting finger trouble

    We have replaced three spotting fingers on one machine in the last week. Can not seem to find the reason they keep breaking. It is not the same pin each time. Is there something going on or is this just really an unlikely coincidence? We have not had to change spotting fingers all year and now three in a row. Pinchaser reported one deck jam. There does not seem to be anything loose, sloppy, no cracks in deck. Clearances appear normal (compared to other machines). Thanks

    Re: spotting finger trouble

    I'd be looking real hard at the deck jam switch/wiring, and what's causing the jams to start with ...

    I've seen a few BENT fingers from time to time, but never one that was completely broken, and no way 3 on the same machine in one week.

    Also, if the timing corresponds with the hiring of a new chaser or other backend worker, be sure they know how to clear a jam properly, unless you want the next failure to be a 1/1 ...

      Agree with Kevin, the deck jam switch must shut the pinsetter off immediately!!! Here's a few other things to check:
      be sure all spotting finger and deck chute bolts are tight...
      lubricate the needle bearings on both sides of the deck torque shaft., the point at which the shaft enters the stationary deck.
      make sure the scissors' cable is in adjustment.. half op-en scissors can bind pins and/or spotting fingers

          Something to look at in regards to your deck jam switch. Be sure it has the return spring installed to help the switch shut off. Part number 12-700041 Page 171 index X127. This little spring can save a 1:1. Amazing what a $1 part can do...good luck.
