5.4.8 Motor Jacket Cover
a) Motor jacket cover [610] is a heavy component.
In the same way as in the disassembly (see Section 5.3.3),
prepare the set-up to lift up the jacket cover by using a
chain block and the eye bolts (hanging bolts) provided at
two spots on top of the jacket cover.
b) Screw in the stud bolts (safety bolts) to the top two spots of
the motor casing [603] flange, and attach the motor jacket
cover gasket [611] that has been applied with oil to the
motor casing flange surface (picture to the right).
c) Apply grease on the entire surface of the motor jacket
cover O-ring [610-1], and fit it in the O-ring groove in the
motor casing (following picture to the left). After fitting the O-ring, fill the O-ring groove with grease
using your finger (picture to the right).
d) Apply grease on the O-ring fitting face of the motor jacket cover (chamfered and uneven edges of
the inner end of the groove).
e) Lift up the motor jacket cover by hooking the lifting tools at the eye bolts. Slowly insert the jacket
cover while allowing it to fit the outer perimeter of the motor casing (following picture to the left).
f) The jacket cover can no more be smoothly pushed in when it touches the O-ring.
Screwing in the two bolts [612] at the mutually opposite positions will allow you to push it in easily.
g) Screw in all the remaining bolts and tighten them with the specified torque (following picture to the
right).
