Air Sealings for Internal Air Pressure

 Packing on the Motor Case
Remove the mounting bolts on the motor case and check the packing where the case is mounted.
Remove the cover for the cable inlet in the motor case, and check the packing where the cover is
attached. Excessive oil in the air that is used for the internal air pressure can damage the packing,
which results in air leakage. Replace the packing if air leakage is found.
Refer to Fig. 9-9 "S- and L-axis Motor Packings" and Fig. 9-10 "R-, B-, and T-axis Motor Packing" for
more information on the packing on each axis motor.
