Baseplate-mounting procedures

Prepare the baseplate for mounting

1. Remove all the attached equipment from the baseplate.
2. Clean the underside of the baseplate completely.
3. If applicable, coat the underside of the baseplate with an epoxy primer. Use an epoxy primer only if you used an epoxy-based grout.
4. Remove the rust-proofing coat from the machined mounting pads using an appropriate solvent.
22 XHD Installation, Operation, and Maintenance Manual
5. Remove water and debris from the foundation-bolt holes.

Install the baseplate using shims or wedges

Required tools:
• Two sets of shims or wedges for each foundation bolt
• Two machinist's levels
• Baseplate-leveling worksheet
This procedure is applicable to cast iron and fabricated steel baseplates.
1. If you use sleeve-type bolts, fill the bolt sleeves with packing material or rags to prevent grout from entering the bolt holes.
2. Put the sets of wedges or shims on each side of each foundation bolt. The sets of wedges should have a height of between 0.75 in. (19 mm) and 1.50 in. (38 mm).

4. Put the machinist's levels across the mounting pads of the driver and the mounting pads of the pump.
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
5. Level the baseplate both lengthwise and across by adding or removing shims or moving the wedges. These are the leveling tolerances:
• A maximum difference of 0.125 in. (3.2 mm) lengthwise
• A maximum difference of 0.059 in. (1.5 mm) across
You can use the baseplate-leveling worksheet when you take the readings.
6. Hand-tighten the nuts for the foundation.

Install the baseplate using jackscrews

Tools required:
• Anti-seize compound
• Jackscrews
• Bar stock
• Two machinist's levels
• Baseplate-leveling worksheet
This procedure is applicable to the feature-fabricated steel baseplate and the advantage base baseplate.
1. Apply an anti-seize compound on the jackscrews. The compound makes it easier to remove the screws after you grout.
2. Lower the baseplate carefully onto the foundation bolts and perform these steps: a) Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce
stress concentrations. b) Put the plates between the jackscrews and the foundation surface. c) Use the four jackscrews in the corners in order to raise the baseplate above the
foundation.
Make sure that the distance between the baseplate and the foundation surface is
between 0.75 in. (19 mm) and 1.50 in. (38 mm). d) Make sure that the center jackscrews do not touch the foundation surface yet.

3. Correct
NOTICE:
Make sure that the sheaves are properly aligned. Proper alignment is necessary to guarantee the correct power transmission and speed ratio, and ensures minimum vibration and long drive life.

Install and tension the belt

1. After alignment of the sheaves, reduce the center distance between the pump and motor shafts so that the belts can be easily mounted into the sheave grooves.
For... Reduce the center distance by...
Overhead mounted motors Adjusting the leveling nuts Side mounted motors Adjusting the motor slide base
Make sure that the center distance between the pump and motor shaft is reduced to the point where the belts can be put on the sheaves without the use of force. Never roll or pry the belts into place, as this could damage the belt cords.
2. After the belts are seated in the sheave grooves, increase the center distance between the pump and motor shafts to tension the belts.
