Removing screw elements from splined shafts
Removing segmented screw elements from a splined shaft is not always easy, since polymer can creep between adjacent elements and degrade into an adhesive. The following is a basic removal method:
- Work on the screws immediately after cleaning and while still hot.
- Clamp one screw in a bench vise so it is horizontal with the screw tip end near the vise (brass or aluminum jaws).
- Unscrew the tip and slide the screw element off the shaft. CAUTION: Heating of the elements or hammering on the elements may cause damages. Please contact our service department for assistance.
- As you remove each element brush/clean the exposed shaft to make it easier to remove subsequent elements.
- Be aware of the fact that for the HP series, the first screw element is not supposed to be removed.
- Consider removing elements from the shafts on a regular schedule as part of your preventative maintenance program.
