death. Always disconnect and lock out power to the driver before performing any
installation or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM)
• Misalignment can cause decreased performance, equipment damage, and even catas-
trophic failure of frame-mounted units leading to serious injury. Proper alignment is the
responsibility of the installer and the user of the unit. Check the alignment of all drive
components prior to operating the unit.
• Follow the coupling installation and operation procedures from the coupling manufactur-
You must check the final alignment after the pump and driver are at operating temperature. For
initial alignment instructions, see the Installation chapter.
1. Run the unit under actual operating conditions for enough time to bring the pump, driver,
and associated system to operating temperature.
2. Shut down the pump and the driver.
3. Remove the coupling guard.
See Remove the coupling guard in the Maintenance chapter.
4. Check the alignment while the unit is still hot.
See Pump-to-driver alignment in the Installation chapter.
5. Reinstall the coupling guard.
6. Restart the pump and driver.

Dowel the pump casing (optional)

You will need the following tools:
• Two number 7 taper pins
• One number 7 taper pin reamer
• 0.3320 in. or "Q" size drill
• Hardwood block or soft-faced hammer
Also make sure that the final alignment is complete.
Dowel the pump casing to the baseplate pedestals in order to make sure that you maintain the
proper pump position.
1. Drill two holes, one in each casing mounting pad, at the locations provided.
Drill the holes through both the casing mounting pads and the baseplate pedestal, when
possible. This makes it easier to clean the metal chips produced from the drilling and
reaming operations.
NOTICE:
If water-cooled pedestals have been provided, then do not drill through the baseplate
pedestal. Doing so can result in leakage of cooling water.
2. Clean all burrs and metal chips from the holes.
3. Ream the holes with a number 7 taper pin reamer to the proper fit with the taper dowel pins.
Insert the pins deep enough that only the threaded portion is exposed when the pin is fully
seated.
4. Seat the taper pins firmly in the holes with a hardwood block or soft-faced hammer.
