There are little to maintenance requirements for a Sky-Tec
starter. You may apply a very small amount of
dry-silicone type lubricant or light LPS (1) to the drive
pinion gear and/or shaft (Lycoming models) to minimize surface
corrosion. But typically the best maintenance for your
Sky-Tec starter is regular use.
Never pressure wash the starter with water or any form of
degreasing agent. Simply wipe it clean to remove any
surface contaminants.
The best thing you can
do for your Sky-Tec is USE IT!
