Fingers not fully opening after strike

[Rep]

Hey guys, thought I'd throw this out for ya. I have one lane when the table runs and feels for pins and runs a strike cycle the fingers do not fully open again as it spots pins dropping pins all over or jamming them in the table. All adjustments I've checked seem fine. Any ideas? I'm sure one of you experts will figure this out

Will check that tomorrow. Didn't really check much aside from standard cell adjustments. I'll give it a look tomorrow, any other ideas please share heh [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Re: Fingers not fully opening after strike

Check the clearance between the pawl and the shifter link. "The Book" says 1/8 to 1/4 inch, but for some reason I remember adjusting those so that you can barely see any space between them. Could be wrong though...its been a while since I worked on 70s. Someone else is more than welcome to correct me on that one.

Second thing is check where the main adjustable linkage snaps onto the two ball studs. I had one ball stud get worn down and it threw all 10 cells out of whack and the machine was puking pins all over the place.

Re: Fingers not fully opening after strike

I did check the pawl. The gap looked good. I will check all the balls on the cells themselves tomorrow, I didn't check em all yet. Just the ones on the wireways. Thanks again for the help guys [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

In my previous post, I had mentioned "good contact". Make sure it is not tight; otherwise you'll bend stuff. Drop the table down to 270 setting pins. Then lift up on the horseshoe. There should be a (you know what kind) hair gap between the cam follower bearing and the surface.
When the scissors are closed, this is what opens them when the table goes to set pins. The pawl adjustment (1/8") is sued for opening and closing of the fingers during table short strokes.

I just wanted to make this clear before someone jumped in and said I will cause you to break stuff. :p

Re: Fingers not fully opening after strike

Kat, will do. Thanks again. Indeed I will check that tomorrow. That might be a little too loose, cuz the fingers do open about 3/4 of the way but that skinny rod (4592 I believe) isn't going in fully. Everything else seems ok and when I push it in just a touch more til it's fully in all the cells are open all the way. This is one of those probs driving me nuts, we have expanders so it's not a big problem but if someone bowls without arrow up on the scorers and the table runs it's a real pain. Thanks again!

Just a quick note look at your Respot Arm Link and make sure that one of your two springs isn't off or broken.

Re: Fingers not fully opening after strike

Visually inspect that non of the respot cell castings are hanging up on the center stud.....as well look for bent wireways contacting the pivot arms.

Welp, she's running as good as new. I checked thru most everything. The cam follower wasn't close at all to being in adj. adjusted the skinny rod, redid the cell adjustments and it's running great. Thanks for the tips guys [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

And that's why I love this place [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img] Was having same problem and couldn't figure it out. Turned out to be the spring that Mike mentioned. Dam stud broke where spring hooks. Now I just need to readjust linkages so the 8 pin will set properly. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Thx guys.

Re: Fingers not fully opening after strike

Hers's a hint to help yu get to the source of the problem a little quicker.
If cells dont't open all the way during respotting (just up &amp; down as feeling for pins), but they do open fine when spotting, it's not the cam link on the table. Look at the respot system from the cells and links to the front end respot cam. If they open fine during respot but not during spotting as after a strike (or after OS if you leave the cells closed), then it has nothing to do with the front drive, respot cam, respot rod, or finger link (pawl). It's definitely the cam link. If they don't open all the way in both circumstances, it's probably a bind on the table, such as the cells themselves or the boomerang levers, or maybe even loose pivot stud(s).
I love respot stuff! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] It's soooo...challenging.

Re: Fingers not fully opening after strike

crank the table with crank through spotting cycle until fingers open, take 7/16" wrench and adjust the little tie rod on the under side of the pawl, until the "hook deal" is tight on the little roller bearing deal. if you still have pins falling over, adjust the "offending" cell accordingly
