5.7 Motor Replacement Process
To ensure IP65 performance, customers may not replace the motor by themselves.
Contact IAI if the belt needs to be replaced.
5.8 Changing the position of the grease fitting and fitting
5.8.1 Changing the position of the grease fitting
The grease fitting can be changed to top, left, or right side positions.
Using a spanner-type torque wrench etc. for the grease fitting and a hex torque wrench etc. for the
outlet bolt, change the mounting position. Fasten the grease fitting and outlet bolt in accordance
with the tightening torque shown in the table.
When changing the position, be careful of peripheral interference if you are using a short-stroke
actuator or a side-mounted motor specification.
After changing the grease fitting, resupply grease and fill the fitting with grease.
Once the seal washer and O-ring have been assembled, their sealing effect is reduced when
reassembling due to rubber deformation, so replacement with new parts is recommended.
