6.2.2.7 By using Yanmar hand
pump
First follow steps (1), (2), (3), (4) on page
26.
(1) Connect the hose from the bottom
and a suction hose to Yanmar
pump with hose clip like shown
above.
(2) Take out the plug from the upper
case cover.
(3) Fill oil by pumping it into drive. Be
aware that oil has to flow up
through narrow parts. Therefore,
pumping will be hard. A few min-
utes waiting in between will help.
After pumping in about 1 liter of oil,
screw in the oil changing plug (do
not forget to insert the gasket).
Please be aware that the drain hose
can easily slip out of the bucket and
cause oil spilling. The hand pump
(p/#: 28210-000080) and rubber
hose (p/#:196440-92970) are avail-
able from Yanmar, and are optional
parts for SD50/-4T. Or any type of
hand pump or rubber hose (Inner
diameter ø14-16 mm) available
from the hardware shop, are us-
able.
(4) After filling, first screw in and tight-
en the plug at the top cover. Then
remove the pump, hose and adapt-
er joint and screw in the oil drain
plug (do not forget to insert the gas-
ket).
