What can I do to get my starter generator to make it to the Time Between Overhaul?

January 2024

There are a great number of starter generators from many manufacturers, all with one thing in common: they all need modifications to greatly improve their lives and reliability.

Three popular starter generator modifications include the following:

• Cooling the unit by increasing airflow
• Ceramic bearings to reduce the friction caused by heating steel bearings
• Longer-life brushes made from a hardened carbon material.

Whatever the mod may be, it is meant to increase the life and time between unit failures.

When your starter generator requires an overhaul, keep these modifications in mind.

Ask Duncan Aviation's Accessories shop what modifications they recommend to get the full life out of your starter generator and alleviate the unscheduled downtime of a unit that didn’t make it to the TBO (time between overhaul).
