Premature sweeping on spares

[jc]

I have a lane that has been sweeping pins on 2nd ball before bowlers can throw. It appears that the fingers aren't closing. Problem is, it doesn't happen everytime, and when we reset the spare and cycle the machine, the problem disappears. Happened about 12 times last night on 1 shift. Not the same pins and no apparent connection with specific leaves.

I'm thinking the fingers need to be adjusted and I'm going to check that today, but is it also possible that the switch or shock is bad and is tripping the cycle?

Any thoughts would be appreciated. Will let you know if adjustment takes care of it.

Really we need more info to determine whether the ptoblem is mechanical or electrical.

For now check your pawl clearance on your respot linkage. While you're there make sure your pawl spring is in good shape.

What type of machines and chassis do you have, and what ball light is on and I'm assuming no pins on deck when you get to the problem lane?

Re: Premature sweeping on spares

Running 82-70s with 1 board chassis.
After 1st ball, table drops to feel for pins, but fingers don't close, so the pins are swept and a full rack is set. If I knock down unneeded pins and cycle to clear deadwood, all pins get picked up properly and reset.
Doesn't happen every time, but way more than it should. Real pain.
Will check pawl and spring as well as fingers, linkages, etc.

I was beat to it. I also say check the pawl gap and spring, that opens and closes the fingers on a respot cycle. Good luck

Adjusted all the linkages and fingers, swapped switches, replaced the stop on the table.......no change. Was working on the pawl when I noticed the shaft was protruding about 2 inches from its housing. Tapped it back into place and the machine didn't have a single problem all night.

Thanks for the help guys.

jc, next time, try to do a thorough visual inspection before replacing anything. This includes anything mechanically involved with (in this case) respotting. You will learn this technique through continual troubleshooting

You will definately save yourself some time and less frustration.

I've also had that shaft work out of it's place a few years ago.
