13.1.1. Installation of the leakage reduction
1. Remove the two hexagon screws (A) and pull out the shaft bearing
(C) by careful turning.
2.
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.
3. Slightly grease o-rings (1, 2) before their installation.
! Do not use grease containing mineral oil for EPDM seals!
Slide the complete leakage reduction instead of the shaft bearing
over the shaft pivot (B) and tighten it with the hexagon screws (A)
at the housing flange (D).
