Commissioning, Startup, Operation, and Shutdown
6. Set the motor back onto the baseplate with the shims in the correct location. Tighten the
hold-down bolts.
7. Loosen the pump and motor hold-down bolts. Confirm that the pump and motor are not
bolt-bound in order to make sure that the final drilled holes will be correctly located.
NOTICE:
Do not dowel the pump prior to this procedure because you will not be able to move the
pump on its pedestals.
Dowel for cold service
Required tools:
• Two number 7 taper pins
• One number 7 taper pin reamer
• 21/64 in. or "Q" size drill
• Hardwood block or soft-faced hammer
NOTICE:
• This procedure must be done only after the pump is properly aligned with the driver on the
baseplate.
• If water-cooled pedestals have been provided, then do not drill through the baseplate
pedestal. Doing so can result in leakage of cooling water.
1. Drill two holes through the pump foot and pump pedestal. Position each hole between the
hold-down bolt and the end of the pump foot at the coupling end on both sides.
2. Ream the holes with a number 7 taper pin reamer to the proper fit with the taper dowel pins.
Insert the pins deep enough so that only the threaded portions are exposed when the pins
are fully seated.
3. Seat the taper pins firmly in the holes with a hardwood block or soft-faced hammer.
If you should ever need to remove the dowel pins, tighten the hex nuts provided on the pins. If
the pins are not seated deeply enough, put a spacer under the hex nuts in order to lift the pins
free when the hex nuts are tightened.
NOTICE:
Always remove the dowel pins before removing the casing. Failure to do so can result in casing
damage.
