Preservation Instructions
The preservation takes place at the manufacturing
plant after the test run or after the assembly of the
component groups resp. and protects the equipment
for a period of 6 months.
Should the equipment not be used before the expira-
tion of this period, the preservation must be repeated
as described below:
SCHOTTEL Rudder propeller / Jet /
Transverse Thrusters
Internal parts:
Fill the gear--box with anti--corrosion oil SHELL oil
S.7294, SAE 30 and crank the power transmitting
parts, to ensure that all internal parts are splashed
with oil. Drain the anti--corrosion oil afterwards.
Steering gear:
Fill the steering gear--box with anti--corrosion oil
SHELL oil S.7294, SAE 30 and crank the steering,
to ensure that all internal parts are s plashed with oil.
Drain the anti--c orrosion oil afterwards.
SCHOTTEL -- Clutches
BMK 80, K 155, K 305 and K 350:
The clutches must be filled with preservation oil
SHELL oil S.7294, SAE 30 and cranked without load,
to ensure that all internal parts are s plashed with oil.
The anti--corrosion oil may be drained off afterwards.
Mechanical clutch:
Cover all open plain parts inside the clutch housing
with preservation oil SHELL oil S.7294, SAE 30. This
must be carried out while the clutch is disengaged. It
must, however, be assured that the friction surfaces
stay free of oil. The clutch must be stored in disen-
gaged condition.
SCHOTTEL Hydraulic Systems
Internal parts:
Flush the system with the ESSO rust preservation
MZ45 and make sure that all internal parts are c ove-
red. Perform all control functions without load. Drain
the preservation oil after. Hydraulic cylinders must
generally be stored with the piston completely retrac-
ted.
General
Fitting surfaces and plain parts:
In case of damage to conserved fitting surfaces,
these surfaces must be cleaned with one of the fol-
lowing solvents: paraffin, solvent naphtha, diesel,
wax remover or similar.
The surfaces must subsequently be sprayed or
coated with VALVOLINE TECTYL 846 K--19.
For storage in seaworthy packaging, the complete
system and all loose items must be welded in plastic
foil at the manufacturing plant. If the packaging mate-
rial is damaged, silica gel units must be attached to
the equipment and the packaging material must be
sealed again air tight.
ATTENTION
!
Before the assembly of fitting surfaces or plain parts
it must be assured that all conserved surfaces are
cleaned with one of the following solvents:
e.g.:
-- P a r a f f i n
-- White spirit
-- Diesel
-- Wax remover
