SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE
c. repeat steps a and b until 0.002 in (0.05 mm) TIR in horizontal plane is not exceeded.
3. Reverse position of dial indicator and bracket and repeat step 2.
4. Remove dial indicator and bracket.
5. Scribe location of hold down bolts on mounting pads, then remove driver from pad.
6. Drill and tap hold down bolt holes.
2.2.5 COLD ALIGNMENT
CAUTION
Since an accurate cold alignment is dependent upon both
pump and motor being at ambient temperature, circulating
oil (if applicable) must also be at ambient temperature.
The term "cold alignment" refers to the alignment of pump and driver when they are at, or near,
ambient temperature. Since thermal growth affects their alignment, cold alignment should be
considered a preliminary task that must be performed diligently before the pump is operated for the
first time. To bring the motor shaft in cold alignment with pump shaft, proceed as follows:
1. Verify that the requirements of paragraphs 2.2.2, 2.2.3, and 2.2.4 have been satisfied.
2. Attach lifting equipment to driver and set it on its mount pads.
3. Check both pump and driver for soft foot at each hold down bolt as follows:
a. Tighten all hold down bolts to the torque recommended by the equipment manufacturer.
b. Install a dial indicator to read the vertical motion of a equipment foot. Loosen the hold
down bolt for that foot until it is finger tight. The vertical motion should not exceed 0.002
in. (0.05 mm). If the vertical motion is excessive, correct it as follows:
1) Loosen all hold down bolts for that piece of equipment.
2) Lift the equipment and place a shim of a thickness equal to the vertical motion of the
foot must be added underneath the soft foot.
3) Re-torque all hold down bolts to the recommended torque and perform the soft foot
check on that equipment again.
If the vertical motion is within specification, then retorque the hold down bolt to the
recommended torque.
c. Repeat step b. for all remaining equipment feet on the baseplate.
4. Check hubs for run out or possible bent shaft conditions and correct, if necessary, before
proceeding with alignment.
CAUTION
When using a double indicator setup, each bracket must be
checked for bar sag. Do not assume that similar brackets
have identical sag.
5. Determine the distance from the bracket mounting point to the indicator reading point.
