4. Using an appropriate solvent, carefully clean any process fluid
build-up from the outside of the stator, between the stop posts and
the stator as shown in Figure 5-2, from the inside of the stator, and
from the flange. If required, remove the stator to clean the inside
diameter as follows:
CAUTION
If the torsion element is coated with Teflon (blue/green color), make sure
the solvent being used does not harm Teflon. Do not scrape surfaces
coated with Teflon. Do not touch the torsion element with a sharp object.
Clean only by using a stream of solvent or soft bristle brush
Do not apply torque to the torsion element while removing the stator
mounting screws. Damage to the torsion element may result.
a. Remove the mounting screws from the top of the stator as
shown in Figure 5-2.
b. Carefully remove the stator as shown in Figure 5-2.
CAUTION
Visually inspect the torsion element wires. They should be straight and
parallel to each other. If they are not, refer to Appendix A and contact
Brookfield Engineering Laboratories, Inc. for a replacement torsion
element.
c. Clean the inside and outside of the stator.
CAUTION
Be careful not to damage the torsion element wires if step d is performed.
d. If normal cleaning procedures are not successful, use
solvent and a soft bristle brush and carefully clean between
the torsion element wires as shown in Figure 5-2.
