Pins under sweep

[Marky_Mark]

Is there any permanent way to stop pins from getting caught under the sweep at the backend in the channel, thus preventing the sweep from moving and causing interlock with the table???

Re: Pins under sweep

if pins are getting wedged between the back of the pindeck and the sweep....the sweep travel is too long.

crank/run sweep as far back as it will go. on the front 10pin side of the machine you'll see the sweep crank arm with a tie rod connected to it

take a 3/4" wrench loosen the lock nuts and shorten the rod to bring the sweep back. my personal preference is to have it just clear the 7-10 line.

Re: Pins under sweep

I had this problem just tonight - so I looked in the manual and, as usual, nothing that will help. I know my head mech. came up with something that eliminates this problem. I'll talk to him and get back to you.
I am definietely a proponent of running the sweep back as far as possible, though. If you run it back far enough to knock out pins (and balls) idleing on the front roller, you never have to deal with that nonsense.
MSBOWL: I am sure that you have Mod IV/V sweeps as I have never had to deal with this with C-90 sweeps. Until you find the actual solution, I would just experiment with lengthening/shortening the tie rod.

Re: Pins under sweep

I have heard that locking down the sweep with a bolt so it doesnt slide up and down would help but Im also thinking that if the sweep couldnt move up in the slide area then something else would break. Correct me if Im wrong!!!!

Re: Pins under sweep

I would think that you do want the sweep bar to slide up and down. Check you sweep shield and slide bars for binding, When they get to the end of the deck the pin should fall into the pit and the sweep bar should pop up to let the pin out.

I remember when I was a kid(it wasnt that long ago ) I wanted to help out the mech., (my brother-inlaw) and I oiled the slide track's of the sweep's and boy was he pee'ed off!!!

Re: Pins under sweep

sometimes lowering the sweep at 1st guard and lowering it at the 4-5-6 line takes care of the problem.

I've heard stories of mechanics adding wieghts to there plastic sweep guards.

You could get the sweeps shown here. <a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank"><a href="http://www.yangjivision.com" target="_blank">http://www.yangjivision.com</a></a></a></a></a></a></a></a></a></a> They have square bottoms!!!

Re: Pins under sweep

Donn't worry about locking down your slide bars. These parts are just carryovers from the first 70's. It's been discovered that they are not necessary, and so the 82/90 pinspotters came out with small and simple one-piece brackets that take the place of the 300- series ones (slotted), and also eliminate the slide bar and trapezoidal bracket, for a fraction of the cost. If the sweep needs to go up over a pin or something, it will by way of the link arms themselves. Check it out: drop the sweep to guard and lift up on the bar.
