Scan Head Drive Screw Damper Adjustment - GE Invenia ABUS 2.0 Technical Publication

Scan Head Drive Screw Damper Adjustment

1. Looking at the Drive Screw Dampers on
the inside of the Scan Head you will find
that one or both Dampers will be
elongated (oval) where the Drive Screw
goes through it.
NOTE: Do not apply grease to damper or
motor lead screw.
2. To fix the displaced damper, pull slightly out on
the Drive Screw; now push the Drive Screw and
Damper back into place. Put a little more
pressure on the Damper then the Drive Screw
when pushing.
When Damper and Drive Screw are in the
correct position, the Drive Screw will be
centered in the Dampers.

When Drive Screw Dampers are not seated correctly and the
Transducer is traveling across the Scan Head and nears the end
of the travel there will be a "binding" sound. This is due to the
Drive Screw Dampers in the Scan Head Brackets slightly
moving out of position. The Motor assembly travels across a
Rail that is mounted in the Scan Head assembly and when one
or both of these Dampers move out of position the Drive Screw
will become slightly bent and cause this "binding" sound as the
Motor travels toward the end of the Drive Screw.
