When pre-engaged starters are used, a
procedure specifying a 30-second delay
between engine crank attempts would be
sufficient to insure correct operation.
This is
common practice by many customers and
such delays are typically programmed into
fully automated starter control systems
found on many packages.
This
"30 Second Rule"
should also be
strictly followed when using the starter in a
"manual mode" or to perform routine
maintenance tasks such as engine timing,
inspections, valve adjustments, etc.
WARNING
Re-engaging pre-engaged turbine starters
during coast-down could damage the starter
pinion and the engine ring gear. Turbine air
starters must
NEVER
be re-engaged during
coast-down or before the starter comes to a
complete stop.
To insure correct starter operation,
customers may choose to incorporate an
electronic or pneumatic control device to
prevent accidental re-engagement during
coast-down. In addition, operators and
technicians should be educated about the
effects of coast-down.
CAUTION
The grease used in the planetary system
has a shelf life of 2 years. Therefore, if the
starter is NOT installed and operated on the
engine for 2 years after the starter is
manufactured, the grease should be
replaced prior to starter operation. The
manufactured date is reflected in the starter
serial number. (Ex: 0602-0567 has a
manufactured date of February 2006).
