one pesky respot cell!

[NightRanger]

okay, heres the skinny.

I have one respot cell that i cant figure out and i'm not even sure if it IS the cell.

at first it was knocking the 3 pin over when it went to pick pins up. after replacing the respot cell, everything worked fine (for a few days). NOW its knocking the 3 pin over when it sets it back down. it will respot a full rack all day long (as long as i'm watching it)but as soon as someone bowls on it-it acts up. it doesnt do it every frame, just often enough to be a pain!

i checked all the linkages, bushings, ect cant really see anything out of the ordinary HELP!!!

Re: one pesky respot cell!

see if the pin cups are tapping the top of the 3 pin as it sets it down. other than that, lube and lube and lube

Re: one pesky respot cell!

well i lubed and lubed and lubed because one of our bigger (and crankier) leagues started tonight. i'll have to check out the cups in the AM, but if the pin is sitting (hanging) at the right height, would the pin cup still hit it?

<font size="2" face="Verdana, Helvetica, sans-serif">Very possibly. If the cups are tipped too much they can hit the tops of the pins, and if they hit bad enough and the pin if offspot just a touch it will knock it over. If this is it just make sure you still get a good solid rack when it spots as you're taking some tilt (and thus toe) out.

I have 2 lanes doing that to my 2 &amp; 4 pin, I bet it's the spotting cups hitting the pins, I'll have to remember to check that....

Night, I will guarantee you Its not the R.S.C.
Everyone including myself agrees its the cups hitting the top of the pins. Good job all!!

Didnt bother posting it myself because everyone had already said it

Fastest way to know if a cup is touching the top of the pin is you'll see the table yoke (nee X-frame) rock back a little as the cells close.

Re: one pesky respot cell!

If it is the cup grazing the head of the pin, check table height first before adjusting cup. With this check, it's possible to have the best of both worlds as you can fix the problem and keep the proper toe-in adjustment. Run table to dead-bottom and check your gap between the table casting and pindeck. If it's too small, it will cause one, some, or all cups to touch standing pins. Before raising, check condition of bearings in lowering yoke assembly (clevis). These bearings (especially the 2 small ones in the "eye" that attaches to the eccentric disc are known to fail or blow out causing the table to sag about 1/8".

Let us know what you find.

Re: one pesky respot cell!

In addition to checking the table height…Check that the table is running parallel to the pindeck. Use your gauge to check height at the 1,7,10.

One other thing to check is that the yolk is not warped or cracked from pins getting in the table, use a straight edge for this.

If everything checks out good and the cup still touches you will have to flag the table and do a full adjustment.

<font size="2" face="Verdana, Helvetica, sans-serif">Good point, I have a warped yoke sitting here in my shop that did just that, knock the 4 over on respot. I keep it as a reminder to everyone why it's important to prevent distributor jams...cause see what can happen.

When it was in the machine, I had to break and remove all the lower ribs in the #4 cups so the head of the pin would "go inside" the cup and not knock over due to the cup being so low from the sagging yoke. After my backordered yokes came in, it immediately got changed.

Re: one pesky respot cell!

First off, let me thank all of you for the wonderful advice. It WAS the 4 cup that was hitting the pin. and it was the ONLY cup to hit pins. after careful examination... i discovered that the yoke had 2 cracks running thru the bearing assy at the 4 pin causing the yoke to sag at that end. So after an exhausting and annoying morning of tearing down the old yoke and building up the new one!! i get to spend my free friday (no leagues tomorrow) trying to get the table and yoke adjusted!!

Again, thank you for the words of wisdom

NR,
We had this problem last fall, and you can make a split for this type break(so if it occurs during league it is a quick fix) and I would suggest, depending on budget and size of house, to carry a preassembled yolk setup for faster morning repairs.
I would of posted earlier, but everyone else had your problem licked, I just wanted to give you a little 'bonus' points info!
Good luck in the morning!

Check the pivot on the the frame weldment could be hitting the underside of the respot cell
