AMF QUESTION/CYCLE

[JEFF KUHNLE]

HELLO
A FRIEND OF MINE WAS ASKING ME A QUESTION ABOUT ONE OF HIS MACHINES. I HAVE NOT WORKED ON AN AMF FOR 2 YEARS NOW AND WAS ONLY RUNNING THROUGH WHAT HE SAID HE HAD ALREADY CHECK OVER.

HE SAYS THE TABLE WILL COME DOWN TO FEEL FOR A STRIKE AND WILL COME BACK DOWN AS THOUGH IT FOUND STANDING PINS AND THEN WAITS FOR YOU TO SHOOT YOUR SPARE.

ANY SUGGESTIONS FOR ME TO HELP HIM OUT ?

THANKS MUCH

Re: AMF QUESTION/CYCLE

sounds simply like a respot wire is touching the table frame

ive also seen boards in the chassis cause it

Re: AMF QUESTION/CYCLE

It could also be caused by a broken or missing spring in a respot cell.

Re: AMF QUESTION/CYCLE

Check the table cable for a shorted wire also!

Re: AMF QUESTION/CYCLE

Too bad he doesn't have MAGIC TRIANGLES. You'd be able to tell right where the problem cell/wire is.
I wholeheartedly agree with all the above suggestions. If it aint one of these, the machine is probably posessed. Call an exorcist.

Re: AMF QUESTION/CYCLE

Some computer systems are over-ruling the respot cell switches(I know Quibica and steltronic will do that, the older versions of accuscore won't), maybe the camera will have to be adjusted or the camera is seeing something els than a pin(or a pin hanging half between the curtain and the machine side-plate,I will ask something about that in a new topic). But I think you will find the answer in the table wiring.

Good Luck

Re: AMF QUESTION/CYCLE

In other words no strike cycle. All answers so far are great. Don't forget, after all of the above, to check your front wireway, from where the upper table cable goes into the machine at the TAC terminal strip all the way to the C2A. Disconnect the table cables at the table plug and try a strike cycle.

BowlEquip,
If you try this, don't forget to make a short between #11 and #12 on the tac terminal board in the channel, otherwise the table will do nothing(waiting for the gps short).

Re: AMF QUESTION/CYCLE

Lampie: already been done...removed GP switches many yaers ago. Not needed with machines using steel respot cell fingers. Heard that many have done the same.

Re: AMF QUESTION/CYCLE

i fought with a fellow mech for years about those....when it was decided to remove respot wires....id make a spectacle of seein how far across the parkin lot i could wing those things (repost wires and all...usin the gp assembly ass a fly weight) and still hit the dumpster

Re: AMF QUESTION/CYCLE

Hey Coors! Didn't you take them apart and save the switches and levers for your front cam switches?? Oh well, it was probably more fun just to fling them.
A funny story: At stahl's pinspotter training class Jamie, my co-instructor, while general-quizzing the class, asked "Now, where can the gripper protection switch be located?" After a few replies (some correct, most not), he said "one of two places: either at the back of the table casting, or, the preferred location is in a box under the workbench!"

Re: AMF QUESTION/CYCLE

About the gps wiring.

I think this can be taken out too, but I don't have experience with it .

Can someone tell me his experience working without gps switch and wiring.

I did start getting out the rest of the table wires, this was o.k. but the company I work for don't allowe me to work without gps.

Thanks

Re: AMF QUESTION/CYCLE

OK Lampie, here's the poop: On the first 82/70's (model A & factory B) the respot fingers were made of cast aluminum. There were two different part #'s: one for the front finger, one for the rear. GP was necessary then otherwise finger would snap if driven over standing pins.
Now, with the steel fingers, which are rounded, if the table descends with the fingers closed, they will generally just float around the heads of the pins and knock some over, without damage.
Consider also: except for flying pins hitting the table and partially closing the cells, or a cam link failing to open the cells fully during spotting due to a bind, why would the fingers ever be closed? OOR, but the table cam link should reopen them.
As far as ccalls go, if the fingers should be closed during a respot and knocks over the spare, the call is a set-up. If the GP were in use, you'd still have a call, and would have to open the cells. It's a wash.
(Make kife easy: Get rid of them)

Bowl-equip,
Thank you, this is the feed-back I need!
I will print this out and let them read this.
