5.4.9 Oil Supply/Oil Return Piping to Motor Bearing
a) For feeding and returning oil for the motor bearing, fix the two pipes (Φ8 mm) connecting the motor
end cover [620] and motor spacer [600] (following picture).
b) Screw in the nuts for the joint located at both ends of the pipe at each joint and tighten them.
The pipes constitute each system of the oil feeding piping from the joint in the lower area of the
motor end cover to another on top of the motor spacer as well as the oil returning piping from the
joint in the upper area of the motor end cover to another in the lower area of the motor spacer.
Connect the pipes cautiously not to confuse them.
