OIL PUMP BLEEDING (50cc-2T)
OIL INLET LINE/OIL PUMP BLEEDING
Fill the oil tank with recommended oil.
Place a shop towel around the oil pump.
Disconnect the oil inlet tube from the oil
pump and clip it.
Fill the oil pump with oil by squirting clean
oil through the joint. (About 3cc)
Fill the oil line with oil and connect it to the
oil pump.
OIL OUTLET LINE BLEEDING
1. Disconnect the oil outlet tube and bend it
into U shape. Force air out of the tube by
filling it with oil.
2. Start the engine and allow it to idle with
the oil control lever in the fully open
position. Visually check the oil flow.
3. If there is no oil flowing out within 1
minute, bleed air from the oil inlet tube
and oil pump.
• Air in the oil tubes will block oil flow
and result in severe engine damage.
• Bleed air from the oil tubes and oil
pump whenever the oil tubes or pump
have been removed or there is air in
the oil tubes.
＊
Bleed air from the oil inlet tube first,
then bleed air from the oil outlet line.
＊
• Never run the engine in a closed area.
• Do not increase the engine speed at
will.
