skipping the 9 & 10

[bamm]

i have more than one dist. that i will often find where it is at 1 pin and there is a pin in every bin except the 9 or 10. sometimes both are not in bin like it is being skipped. i know how to correct if it was the 5 or the 6 but i am asking for help.

THANKS

Check the clutch plate and stop fork on your Dist.
Also check the universal on the B/E moter drive shaft. Its a sharp angle on the driveshaft for the 7,9&10 pin. Bad joint will cause it to jump past the fork.l

You might also check both ball bearings and the drive housing they sit in. I've seen where they get indented from wear. Other then that, Simbowling problebly had the answer.

This doesn't sound like a distributor problem. Sounds to me like a Shuttle problem.

Re: skipping the 9 & 10

check that the telescoping assemble on the distributor is parralell with the trip rod, several machines at my old bowl skipped beck row pins because of it, make sure its parralell with the rod about halfway between the 2 nylon wheels and remains so all the way thru its travel, make sure the bushings at both ends of the trip rod are sound without excessive play and make sure the stop blade lines up on clutch plate and trip rod and that it is in good condition, if these posts dont cure it, come back to us.
(you might want to check that the pinwheel isnt catching the o-pan because if it catches it and makes it jump, the jump can bounce the flipper on the end of the dizzy thru a location cycle)

Re: skipping the 9 &amp; 10

I got to agree air force, unless the pins are sitting in the cups. But from what I read, I was thinking there was no pins in the bin or cups. If thats the case, Then the shuttle has no role in this problem.

Never overlook something that dosent necessarily sound like the cause. The shuttle could (although it isnt the first place I would look) play a roll in this problem..as could intermintant bin switch sticking. These are long shots, but discount something and inveribly it will turn into your problem

This is a rare place for the distributor to skip, at least ive never seen it. Sounds like the shuttle could be double shuttling the pins. Meaning if the 10 pin bin has two pins in it, they both shuttle through.

I guess unless a machine has 21 pins in it there will never be two 9 pins, unless strike cycle isnt working.


If I seem to be rambling, Im done now!

Re: skipping the 9 &amp; 10

I've seen this happen from a worn or misadjusted stop on the clutch... at the 9, it can bounce past the stop and return to the 1 position w/o placing a 9 pin. Also caused by a trip assembly that's slow to return (binding/sticking) after delivering the 10 pin. It's uncommon, but it does happen. Most times it's the opposite... the distributor doesn't trip on the first 9 pin delivered, so it places a 2nd one before moving back to the 1 bin.

Try moving the distributor to another lane. If the problem follows to that lane, then you can be pretty sure that the problem is in the distributor.

Re: skipping the 9 &amp; 10

I've had the same problem. What I found was, the carraige on the distributor was too loose. When I tightened them up a little it started juming bin positions when indexing. What I found was the distributor tubes were bent. Replaced with good rebuilt and so long, good-bye, and adios problem. You could also just replace the carraige with a rebuilt if you like.

Then you don't know if the problem followed it, or if you created it during the adjustments.
