Installation of the leakage reducer
- Remove the two hexagon screws (A) and pull out the
shaft bearing (C) by careful turning.
- If the leakage reducer is not equipped with the guides (3) and the
two O-rings (1, 2), these parts can carefully be dismantled from
the shaft bearing (C) and used.
- Lightly grease O-rings (1, 2) before their installation.
!!! Do not use grease containing mineral oil for EPDM seals !!!
- Slide the complete leakage reducer instead of the shaft bearing
over the shaft pivot (B) and tighten it with the hexagon screws (A)
at the housing flange (D).
