Double Screw Wear Check Sheet
Below is the procedure to check the wear of you double screw and housing in your Vemag or H&S model AC stuffers.
Make sure screw & housing are clean.
Place screw & housing on level surface or slide into machine.
Push the housing all the way in until it stops then pull back out 2 inches.
Slide screw in housing until 2 inches are sticking out of housing.
Rotate screws until there is material at the 12 o'lock position, push the screws in until they are flush with the front of housing.
Using a standard set of feeler gauges check the gap at the 12 o clock position.
Repeat for opposite side, record measurements.
We consider the screw and housing worn out when .016 -.020 inches of gap are obtained, depending on product. If you have any questions, please give us a call at 800-752-7507.
