Goulds Pumps 3640 - IOM - Manual (Page 50)

Commissioning, Startup, Operation, and Shutdown
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.
Dowel for hot service
Required tools:
• One 1.00 in. dowel pin
• One 1.00 in. reamer

• 1.00 in. magnetic-based drill
NOTICE:
This procedure must be done only after the pump is properly aligned with the driver on the
baseplate.
1. Remove the hold-down bolts from the pump feet that are furthest from the coupling.
2. Scribe a mark midway between the end of the pump foot and the hold-down bolt hole
centerline, parallel with the pump axis.
3. Re-torque the hold-down bolt between the pump foot and the pump pedestal.
4. Mill or grind a spot on the pump pedestal to make it flush with the pump foot.
