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.
5.21 Doweling the pump casing
The pump casing must be doweled to the baseplate in order to maintain the proper pump position.
When the driver is mounted at the factory, the driver is not doweled in order to allow for final field align-
ment.
NOTICE:
You should dowel the driver only after completing the final hot alignment.

5.21.1 Installing the driver

1. Confirm the pump is centered on its pedestal so that the hold-down studs are centered in the pump
foot clearance holes with the pump dowel pins installed.
2. Place the driver on the baseplate with proper shaft separation (DBSE = distance between shaft
ends).
3. Tighten the pump hold-down bolts as described in the applicable pump doweling sections below.
4. If the driver was installed at the factory and the driver hold-down bolt holes have already been dril-
led and tapped in the baseplate pedestal, proceed to step 9.
5. After you have determined the correct driver location on the driver pedestal, mark the location of the
driver on the pedestal with a hole punch through the hold-down bolt holes in the driver feet.
6. Remove the driver, then drill and tap the punched holes on the driver pedestal.
NOTICE:
Scribe the driver shims in order to return them to the correct location on the driver pedestal.
7. Set the driver back onto the baseplate with the shims in the correct location.
8. Confirm the driver is not bolt-bound.
9. Tighten the driver hold-down bolts and confirm alignment.
10. Run the unit under actual operating conditions for enough time to bring the pump, driver, and asso-
ciated system to operating temperature.
11. Shut down the pump and the driver.
WARNING:
Failure to disconnect and lock out driver power may result in serious physical injury or death.
Always disconnect and lock out power to the driver before performing any installation or main-
tenance tasks.
• Electrical connections must be made by certified electricians in compliance with all in-
ternational, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM)
for specific instructions and recommendations.
