Stuck in second ball

[ringinten]

One of our lanes is stuck in second ball. It picks up pins (or nothing) with the scissors and puts them back down on every cycle. It never goes into first ball cycle. The moving deck never moves and it never goes all the way down.

I'm an amf guy, but it sounds like it is stuck in first ball. ( second is where it sets pins )

Okay. First ball. Thanks.

If A/2s or jetbacks check for an inverted trip lever, if As, check deck holding hook operation

Or missing or brocken hook selector bearing

The Hook it's not holding the deck up and let the detector knows it's time to set a new rack of pins

I've had it where the 1st & 2nd ball lever on the detector that pushes against the micro switch was not making contact with the micro switch and it caused it to stay on second ball. So could be pushed to far in if it stays on 1st ball.

You may have a bad bearing on the 2:1 if you have scotch yokes. When the bearing goes bad...the deck can not be lifted high enough to catch on the deck holding hook. Can you push the deck holding hook down and have it catch on the deck post?

I've had a machine do the same thing that was missing the block on the end of the scotch yoke adjusting screw.

After reading Steve's post, right before I left Knoxville, I had a machine where the Deck Lift Shaft had cracked in the center. It really pained me to move the bowlers on that pair because one of the guys was on the front 8... Since the Lift Shaft was nearly $800 or more new.. it took a little looking around and information from the district mechanic to land a new one.

[Steve Stafford (JBEES)]

Even though $800 (due to your location) may seem a bit high...the new ones are made so much better than the previous versions. I think you would be pleasantly surprised if you ever need to order one. One of the few cases where a new design is far better than the earlier design in durability.

[amechwannabe]

agreed, but the deck lift shaft failure was in the middle of the big recession in late 2008. The man wasn't going to spend the extra bucks for a brand spankin new one. And one of the reasons I went back to being a mechanic wanna be.. hence the name... Where I am now, the work statement says that I only have to have 6 machines of 8 working... The discussion the other day was that it is just as cheap to keep 8 running as it does 6 unless I have a major part (which this would be a major part) to fail.

[Kanga (James)]

The import cost to get a new shaft is ridicules here. This is what I use to repair broken ears in our Japanese centres.

Nice repair Kanga! I have never had to deal with a broken deck lift shaft yet....ooops its coming now for sure!
