HVDP SERIES ASSEMBLY, MAINTENANCE & CLEANING INSTRUCTIONS
SECTION 1: MOTOR INSTALLATION AND REMOVAL
1. Check the rotation direction of the LR motor.
WARNING: Motor rotation must be clockwise when viewed from the fan end of the motor. Rotating the motor in the wrong direction
will cause damage to the pump.
2. Remove the motor adapter bolts (see Figure 2) and separate the motor adapter from the motor.
3. Thread the motor adapter onto the LR drive assembly. Hand tighten the motor adapter.
Note: Threads are left-handed. Also, thread lubricant is recommended to ensure smooth, bind free assembly.
4. The LR motor coupling consists of two 5/16” diameter pins welded to a hub. The LR drive assembly coupling has two slots that
receive these pins. Align the pins of the motor coupling with the slots on the drive assembly coupling and slide the motor onto
the drive assembly.
Note: Make sure the coupling is engaged properly and the motor adapter face is flush with the motor face.
5. Rotate the motor until the motor adapter mounting holes align with the threaded holes in the motor face.
6. Install the motor adapter bolts and torque to approximately 7 ft.-lbs. (9.5 N•M)
HVDP-LR REMOVAL:
1. Remove the LR motor adapter bolts.
