Maintenance Instructions and Parts List
1. Determine type of motor (inline or parallel).
2. Referring to the appropriate illustration and specification table, assemble coupler to motor shaft using Loctite
609. Make sure to measure the “A” dimension from the mounting face of the motor. Do not measure off of the
pilot. Tighten set screw (if applicable).
3. Make sure to torque motor mounting hardware as necessary (if applicable). Refer to page 14 for torque
values.
NOTE: Use precautions contained with Loctite or any other adhesive used in assembly.
Motor Coupler and Pulley spacing
Motor coupler and pulley spacing refers to the required position of the coupler or pulley on the motor
shaft to ensure correct coupler or belt engagement.
