Screw Press Seals
1. Turn the screw press out so that there is a distance of at least 1 in/2.5 cm between the
large union nut at the end of the barrel and the capstan hub.
2. Unscrew the union nut and withdraw the lead screw assembly (24) from the barrel,
taking care not to drop the rambler (22).
3. Inspect the seals for signs of wear or damage. Replace as necessary.
4. The white anti-extrusion ring (21) is a PTFE spiral and can be removed by unwinding
it from the rambler.
5. Do not use a sharp tool that will scratch the surfaces of the rambler when removing
the rambler seal. This can cause the seal to leak when reassembled.
6. Ease the replacement rambler seal over the front of the rambler and into the groove.
7. Wind the new anti-extrusion ring into the groove in the rambler behind the rambler
seal.
8. If the rambler is separated from the lead screw, ensure that the ball (23) is correctly
fitted before reassembly.
9. Verify that the rambler assembly is correctly located on the end of the lead screw
assembly. Carefully introduce the rambler into the open end of the barrel, making
sure that it does not tilt when entering the barrel.
10. Push the lead screw assembly fully into the barrel, ensuring that the key in the nut
locates correctly in the slot in the barrel.
11. Re-tighten the barrel union nut.
