spotting issues aghhhhh

[Battybird]

hi guys so .........
it spot's 99.9999999 percent of the time then it will not spot . have watched it and the solenoind every now and again will 'Jump' (the chinese puzzle gets depressed ) this in turn lifts the latch up and so it doesn't spot .
solenoid is fairly new and doesn't look worn in any way .
thinking i may have to chage the solenoid out but was wundering if there was something i was missing .

On that .0000001% of the time, is the table coasting past 355 thereby not allowing the eccentric to unlatch?

Check for a worn roll pin in the eccentric latch assy. too

You mentioned that you recently change the solenoid. Here in could be the source of your trouble. The newer ones have a sightly longer stroke than the original ones. This is the cause of the shuttle operator not locking up in spotting. For a quick fix,.... take the rubber washers out from under the solenoid and tighten it down. You should now have enough room so the operator can lock up. I try to keep the older solenoids in stock if I can get them. Last week I had a friend call me with the same problem.

In order for the machine to successfully and consistently spot pins, 3 things must happen when the spot solenoid pulls in:

1. The spot latch locks on top of the spot lever to tilt the cups
2. The shuttle blocking finger lifts up to shuttle pins
3. The trip lever trips the table drive to allow the table to go all the way down

If any one of these fails it will not spot pins. And, in order for all of this to work (besides any other parts that may be bad and assuming the table is stopping early enough at home position) the shuttle operator assembly must be functioning properly and for that to happen when the spot solenoid pulls in the links under it must raise to a position to lock the assembly- the energy of the spot solenoid itself pulling in and holding is not what makes this work, it's the linkage being held in a locked position by the solenoid that causes spotting.

A quick way to determine if the shuttle operator assembly is not locking rigidly when the solenoid pulls in is with the machine LOTO, manually and fully engage and hold the solenoid in and at the same time try to lift the trip lever for the table drive, it should stay in a locked position. If you can easily lift it then either the linkage under the solenoid is worn or the solenoid is just not pulling in far enough to lock the assembly. You can try as the DOC says and remove the rubber washers which will allow the solenoid to pull the linkage up higher. In order for the assembly to lock into position the two links inside and under the solenoid must be pulled up high enough that they are straight across from each other. If they don't the assembly does not lock the table drive trip lever into position and what can happen is it will work most of the time but every once in awhile, or not at all, it won't spot pins and what happens is as the trip roller on the table drive passes under the table drive trip lever it can force it up which moves the rest of the linkage and can cause the spot latch to miss the spot lever. In other words it looks like it jumps or pops off.

Had a similar problem a while back - turned out it was the 070-006-281 spring links worn. Aim to change them all in time as the solenoids need changing.

I ran into this a few years back. Drove me nuttier than I am normally til I decided to measure the stroke length. Did the rubber washer thing as well.

I've also noticed that sometimes the new solenoids like to buzz, like they are not pulling in all the way eventhough they are.

so.......... i changed out the solenoind , bent pin and dodgey looking spring ....shutlle rod was bent so did that while i was there as well ....changed out the roll pin , welll basically it fell out lol .....glanced across at the ecc drive to find that was coming apart so did that as well .
tested rigorously ...... they spot lovelly , a few cup adjustments needed but still looks sweeeeet . lol.

thanks for pointing me in the right direction .

hopefully there won't be a note for me in the morning .
