strapping that covers the clamp (207).
3. Unscrew the worm gear and remove the wiper
(202).
4. Thread the strapping through the new wiper (202).
5. Insert the strap end through the clamp (207) and

Platen (201) until the wiper ends are butted tightly
together.
7. Apply a lubricant to the wiper (202). Use a lubricant
that is compatible with the material to be pumped.
