5. Repeat the previous steps until the permitted reading value is achieved.
NOTICE:
The specified permitted reading values are valid only at operating temperature. For cold
settings, other values are permitted. The correct tolerances must be used. Failure to do so
can result in misalignment.
Perform complete alignment for a vertical correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P)
do not vary by more than 0.05 mm | 0.002 in. as measured at four points 90° apart.
1. Set the angular and parallel dial indicators to zero at the top-center position (12 o’clock) of
the driver coupling half (Y).
2. Rotate the indicators to the bottom-center position (6 o’clock).
3. Record the indicator readings.
4. Make corrections according to the separate instructions for angular and parallel alignment
until you obtain the permitted reading values.
Perform complete alignment for a horizontal correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P)
do not vary by more than 0.10 mm | 0.004 in. as measured at four points 90° apart.
1. Set the angular and parallel dial indicators to zero at the left side of the driver coupling half
(Y), 90° from the top-center position (9 o’clock).
2. Rotate the indicators through the top-center position to the right side, 180° from the start
position (3 o’clock).
3. Record the indicator readings.
4. Make corrections according to the separate instructions for angular and parallel alignment
until you obtain the permitted reading values.
Grout the baseplate
Required equipment:
• Cleaners: Do not use an oil-based cleaner because the grout will not bond to it. See the
instructions provided by the grout manufacturer.
• Grout: Non-shrink grout is recommended.
1. Clean all the areas of the baseplate that will come into contact with the grout.
2. Build a dam around the foundation.
3. Thoroughly wet the foundation that will come into contact with the grout.
4. Pour grout through the grout hole into the baseplate up to the level of the dam.
When you pour the grout, remove air bubbles from it by using one of these methods:
• Puddle with a vibrator.
• Pump the grout into place.
