5.3.10 Motor Spacer
(NHM30/NHM43: 29 kg, NHM60: 37 kg)
As long as no gas or oil leakage has been checked from the joint section of the motor spacer gasket
[601] in a daily inspection or monthly regular inspection, there is no particular need to overhaul the
motor spacer [600].
If any gas or oil leakage is verified, replacement of the motor spacer is required. To dismount the motor
spacer, loosen and take off the 12 bolts [602] fixing the motor spacer to the crank case.
After replacing the gasket, mount the motor spacer.
a) Remove the bolts in two spots on the top of motor spacer, and screw two stud bolts (safety bolts)
into the appropriate bolt holes.
b) After loosening the remaining bolts, remove every bolt while supporting the motor spacer by hand
(following picture to the left). Pulling the motor spacer toward yourself allows it to be removed.
c)
After removing the old gasket and cleaning the flange surface, mount a new gasket that should be
applied with oil (picture at right above). Allow the positioning pin hole of the motor spacer and the
position of oil hole to meet the counterpart.
d) Using each stud bolt as a guide, mount the motor spacer. Mount the motor spacer in such a way
that the oil return tube [PT1] in the motor casing comes immediately below, screw in the bolts, and
tighten them with the specified torque.
