sweep adjustments

[mekanic]

im having a problem with a machine were the sweep goes too far back into the pit and when it comes up, it hits the frame. i thought it could only do one or the other. not both at the same time. i did all of the sweep adjustments so im stuck. it's getting frustrating.

hey mekanic

Here are the instructions i got from stahls for adjusting a sweep and they have worked every time for smoothing out a sweep.

They are as follows..........

1. Crank the sweep as high as it will go at the 0 position. Using the long rod on each side of the sweep arms (not sure the part #), adjust them so that each side of the sweep is 23.5 inches off the pindeck from the 1-2 board. Make sure to tighten the jam nuts back up.

2. Crank sweep to 66 guard position. Using the long threaded link on each side, 15/16" nut, adjust the sweep to be 5/16" off the gutter for each side. Again make sure to tighten the nut back up.

3. Crank sweep to 4 5 6 row, and adjust the saddles on each side of the frame of the machine so that the sweep is 5/16" off the pin deck on each side. Lower the saddle to raise the sweep and raise the saddle to lower the sweep. If you need more height on either side, you can add washers behind the rubber bumper on the telescoping link.

4. Crank the sweep as far back as it will go just until it starts to come forward again. Adjust the main rod coming off the sweep crank arm so that the back edge of the sweep is lined up with teh back edge of the 7 and 10 pin spots.
Again remember to tighten things back up.

That should smooth out the sweep. Dont forget to check your cams for proper stopping positions.

Re: sweep adjustments

Not exactly the order I use, but it is sound....Sweep adjustments arent AS picky as the table when it comes to order....(depending on what model of "gremlin" you have lurking in the dark corners) Main rule..main link too long, your sweep will colaps into pit...too short, it wont knock pins into pit...the two longer rods adjust the sweep hiting the frame.I usualy put a pin on the 7 and 10 spots and adjust untill the sweep just starts to push them...in motion it will knock them into the pit

U R Dead On Balls I Attended A Course @ Sthal's 3yrs. Ago In Applevalley, MN. And This Was The Same Way I Was Taught To Adjust The Sweep.

Re: sweep adjustments

had a problem like that-sweep traveled too far back and ran into machine at zero, of course after checking all the adjustments, believe it or not, it turned out to be that the sweep crank arm was longer than it sould have been-strange, I have never come across this before. After I pulled the crank off the machine and compared it to the two good new spares and to ones on the other machines I concluded it was almost an inch longer from the center of each hole (the hole where the sweep shaft goes and the hole where the bolt for the 3162 rod goes). Changed it and everything fell right into place, got it adjusted perfectly with room to spare. Needless to say I "took care" of the one I pulled off with Mr. sledgehammer so this could not possibly happen again. Something you might want to look at- sometimes you find some strange things on these machines, especially older ones!
