Every 1200 hours

26. Hydraulic system

AQD70. Optional equipment on other engines.

Change the oil and the filter element after every 1200
hours, or at least once a year. See the instruction book for
the Aquamatic drive type 750, where venting and changing
are described in greater detail.

27. Reverse gear, changing oil

Change the oil after every 1200 hours of operation or at
least once a year. However, for a new or reconditioned re-
verse gear the oil should be changed for the first time after
100 hours of operation. When changing the oil the filter
element should also be replaced (SCG), for other reverse
gears the oil strainer should be cleaned.

Remove the oil dipstick.

Suck up the oil from the Twin Disc reverse gear with the
scavenging pump, and a hose which is connected to the
pipe for the dipstick.

For the Borg Warner and SCG type a pipe can be inserted
through the hole for the oil dipstick and the hose can be
connected to this pipe by means of a reducing nipple.

Alternatively, the oil can be drained off by removing the bot-
tom plug.

Collect the used oil and hand it over to a service station
or disposal depot. Never pollute the water by discarding
the oil overboard.

After filling oil start the engine and run it for a few minutes
at idling speed. Then check the oil level on the Twin Disc
gear with the engine running at idling speed and the gear
in ”Neutral”.

The level in the Borg Warner and SCG reverse gears
should be checked immediately after the engine has stop-
ped.

Also check that the oil pressure in the reverse gear is nor-
mal and that there are no leakages and that no abnormal
sounds can be heard.

See also ”Precautions in connection with oil changing”, be-
low.

Precautions in connection with oil changing

Applies to SCG 350 HDMK3: replacing the filter.

Unscrew the housing, remove the filter and clean the hous-
ing by washing in white spirit or fuel oil. Replace the rubber
gasket if necessary and fit a new filter.
