Service Kits
You should service your winches at least once during 
the preseason. However, twice a season is best if your 
boat lives in salt water. If you race your boat hard, you 
may want to maintain your winches before every regatta. 
Keep your winches clean and operating smoothly by 
flushing frequently with fresh water. Check pawls and 
springs, bearings, gears, and spindles for signs of wear 
and corrosion.
For more details, consult the maintenance manual.
Installation manuals and parts lists are available 
online at www.harken.com.

Q&A
WHICH PARTS DO I GREASE AND 
WHICH DO I OIL ON MY HARKEN 
WINCHES? 
Grease all metal gears and
roller bearings with Harken
Winch Grease. It’s highly resistant 
to salt and fresh water, works in all 
temperatures, and protects against 
corrosion. NEVER grease pawls
or springs because grease causes 
them to stick. Instead, lubricate 
with Harken Pawl Oil for optimal 
rotation. Radial winches and 
carbon winches have composite 
roller bearings that do not need
to be lubricated.
