d) If it is necessary to replace the seal
housing (97) or O-ring (101) loosen the nut
(98) until it disengages with the housing.
Pull the housing out from the front of the
rotor case and remove the O-ring from it's
groove.
Re-assembly:
a) If the housing (97) has been removed,
refit a new O-ring (101) to the groove in the
outer diameter of the housing.
b) Lubricate the O-ring and slide the housing
into the rear of the rotor case until it engages
with the retaining nut (98). Tighten the nut.
c) Fit a new O-ring (99) into the groove in the
sleeve.
d) Lubricate the O-ring and slide the sleeve
(96) into the rotor. Make sure the drive pin in
the rotor is located in the hole in the sleeve.
e) Lubricate the dynamic O-ring (100) and fit
into the seal housing.
f) Slide the rotor onto the shaft ensuring that
the leading end of the sleeve slides
smoothly through the dynamic O-ring.
g) Re-fit the rotor retaining screw and O-ring
to the rotor and tighten to the correct torque
(See Performance Data Sheet).
6.08 Double O-Ring Seal
(
Hy~Line
option only)
This seal is designed such that the primary
dynamic O-ring can be replaced without
removing the rotor case. It will be necessary
to remove the end cover to gain access to
the seals. Before disassembling the seal
ensure that the flushing system, if fitted, is
switched off.
Removal :
a) Remove the rotor retaining screws (59),
being careful not to lose the O-rings (58).
Withdraw the rotors from their shafts. The
rotor has a small sleeve (97) inserted into
the rear face, this should come out together
with the rotor. If it does not then it will be
necessary to remove this sleeve from the
rear of the rotor case.
b) Remove the sleeve from the rotor and the
O-ring (99) from the groove in the sleeve.
c) To replace the dynamic O-ring (100)
simply pull it out from the bore in the rear of
the rotor case.
d) If it is necessary to replace the seal
housing (104), secondary dynamic
O-ring (100) or housing O-rings (102) it will
be necessary to remove the rotor case (51).
See section 6.10
e) Once the rotor case has been removed
the 4 bolts (83) can be removed and the
flushing housings (104) withdrawn.
f) The seal housings (97) can now be
withdrawn from the rear of the rotor case.
g) The O-rings (102) can be removed from
their grooves on the outside of the seal
housings and the secondary O-rings (100)
removed from the inner bore of the
housings.
Re-assembly:
a) If the housings (97) have been removed,
refit new O-rings (101 & 102) to the grooves
in the outer diameter of the housings and a
new secondary dynamic O-ring (100) to the
groove in the inner bore of the seal housing.
b) Lubricate the outer O-rings and slide the
housing into the rear of the rotor case.
