4.2.3 Assembling After Applying Sealing Bond
1. After applying sealing bond, pay attention to the following and
immediately perform assembling.
• Remove any dust, dirt, foreign objects, and oil on the sealing
surface.
• Align the screw hole positions etc. before applying the sealing bond,
and then contact the surfaces. Without this procedure, unevenness
of the sealing bond on the sealing surface may decline the sealing
efficiency. And it may cause grease leakage.
• The rust preventive oil is applied inside of the speed reducer. Imme-
diately perform assembling so that the rust preventive oil does not
flow out to the sealing surface.
2. After assembling, fix them with screws as soon as possible. For
tightening the screws, tighten them by using the tightening torque
indicated in
chapter 5 “Disassembly and Reassembly of the Motor”
and
chapter 6 “Disassembly and Reassembly of the Speed Reducer”
.
3. By using a waste cloth, wipe the exceeded sealing bond after
assembling. (Refer to
“
Wiping Stray Sealing Bond
”.)

Example)
NOTE
If grease is filled before the sealing bond is solidified, it may
cause the grease leakage. After tightening the screws,
leave it 30 minutes or more, and then fill it with grease.
