Screw that holds down the blade in cwnter

Believe it can be done. You might have to file or shave the new arm a little then seat it as best
as possible and tap it in place with a screw driver and hammer. If you do manage to attach
the new arm and the fit is a little too snug when you latch down the cover, file the upper tip
of the arm for a little more tolerance. Also, believe it or not, a worn blade will produce less
vibration. There is a set screw bottom center. With the juicer fully assembled, unlock it,
turn it clockwise until feed chute contacts the shredder blade and back it off a half turn.
You now have the proper gap between the chute and blade.

Yes the blade is hitting it when the juicer vibrates
severely. I have an Acme, 21 years old, and found
very difficult to control vibration especially with a
new shredder blade. If you are handy this is what
to do. Order a new cover from omega, cover design
has changed so you will need the plunger also. This
may sound incorrect, but you will have to use a small
file to file down the cutting burrs on the blade a fraction
of an inch. Then with the juicer fully assembled, unlock
the set screw on the center of the bottom and turn it
clockwise until the chute contacts the blade then back
it off a half turn. Now the chute to blade gap is set
correctly. In filing down the burrs you make the blade
a little duller but you also narrow the gap and feed
the produce through more slowly and evenly. This
comes from 21 years of using this machine. With
a new blade I could not control the vibration no matter
how I fed the thing. If this sounds a bit too much get
rid of the Omega and try the pulp ejecting type. The
Miracle MJ1000 is a nice little juicer for about $130.

Both the Omega and Acme juicers vibrate no matter what you do. I found a worn shredder
blade actually produces less vibration. However this involves filing the cutting burrs down
and resetting the blade to chute gap. If you're up to it, take the blade out and file each row
of burrs about halfway down. Then with the juicer fully assembled, unlock the set screw on
the center of the bottom, turn it clockwise until the chute contacts the blade, and back it off
a half turn. The set screw actually raises and lowers the motor spindle. Both companies
would not agree with this, but this solution comes from operating my 21 year old Acme.
I recently replaced the blade and the juicer immediately began tap dancing. Went back to
the old blade.

I've had an Acme for 21 years and I don't care
what anyone tells you-they vibrate. After years
of trial and error I found mine vibrates less with
a worn blade that I sharpen with a drill. With
a new shredder blade you actually have to file
down the cutting burrs about one third and
adjust the blade to chute gap by unlocking
the adjusting screw on the center of the bottom,
turn it clockwise until blade contacts chute, and
back it off a half turn. Apparently with a slightly
duller blade, smaller gap, the produce goes through
more slowly and evenly. Also severe vibration will
cause the blade to jump up and chip the chute.

mcdevito75 here, The filter unscrews from the blades, you should have a tool with the juicer to help un-screw the filter.

I've had one for 21 years and when I replaced the blade the same thing happened.
The blade is not supposed to be held firmly in place so it can slip intentionally to
minimize vibration. If you bought the juicer new, think back, and I believe you will
remember the vibration problem. I seems with a worn blade they vibrate less. The
motor is very durable and uses roller bearings like on a skate board. I went back
to the old blade, which I sharpen with a drill using a small bit.

The hot water did work for mine. Here is the solution I discovered:

After removing the food plunger and juicer cover: (1) Unscrew the 3 screws that hold the cutting blade plate in the center of the basket and lift off the cutting blade plate; (2) Unscrew the base counterclockwise (it will unscrew from the threaded center piece) and lift it up; (3) Lift off the basket and juice bowl. Now you can clean the basket and juice bowl.

To reassemble, reverse the process.

Go to Lowes, to the cabinet knob dept. Get a cabinet knob that matchs the holes in blade. You can always bend the screw a tiny bit if needed to fit. Put the screws into cabinet knob, and tighten. Cut the heads off and you are ready to go. They have a knob that is stainless steel, just a flat piece across the top, an 2 straight pieces that go down. I think it was $2.97. It gives good grip, and takes the blade right off.

Hello, First, make sure the screw on clamp that holds the blade down is centering the blade correctly. Also make sure it tightens down firmly against the blade. Wiggle the blade to ensure it is mounted securely. If this doesn' fix it try your old blade again. If your old blade works you may have a bad, unbalance blade but I would suspect he screw on clamp knob may be somewhat worn and not securing the blade causing it to run "out of round" when a piece of vegetable pushes on it. If everything looks good with both blades and the blade securing knob it could be a worn bearing on the juicer. Try wiggling the motor shaft and see if there is any play in it. I have an ACME 6001 that is quite old so I wouldn't suspect the bearings are going. One other thing, does the bowl take 3 to 5 minutes to stop spinning when you shut off the motor? If it does then the shaft and bearing are probalby ok

Good luck with it...gary

After about a half hour I finally figured it out. I'll go through all the steps.

1. Remove pusher from chute.
2. Pull the locking bar down over the spout.
3. Remove lid.
4. This part is tricky. Stick the orange crescent tool into the blade holes and while holding the filter basket steady with one hand, turn the blade couterclockwise while pulling up.You do have put a little muscle into it. And remember, if you don't hold the filter steady, the whole damn thing just spins.
5. Remove the receptacle.

Good juicer, but it seems unnecessarily complicated.
