How to Service Harken Winches This Winter

Winter is the perfect time to service your Harken winches.

With fewer days on the water, it's the ideal opportunity to tackle essential maintenance before the new sailing season begins. A little time spent servicing your winches now can improve performance, extend their lifespan, and help avoid costly repairs later.

Why Winch Maintenance Matters

Your winches work hard every time you hoist, trim, reef, or tack. Over time, salt, dirt, moisture, and old grease build up inside the mechanism, making the winch harder to operate and increasing wear on internal parts.

Annual winch maintenance helps:

• Keep winches turning smoothly
• Protect gears and bearings from wear
• Prevent corrosion
• Ensure pawls engage reliably
• Extend the life of your winches

If you sail regularly in saltwater, more frequent servicing is worth considering.

What You'll Need

Using the correct products is essential.

Harken Winch Grease

Harken Winch Grease is designed specifically for winch gears and bearings. It provides long-lasting lubrication while resisting water and corrosion. Apply a light coating after cleaning all components.

Harken Pawl Oil

Never grease the pawls. They need to move freely to engage correctly under load.

Harken Pawl Oil is specially formulated for pawls and springs, allowing them to operate smoothly without sticking. Just a few drops is all you need.

Harken Winch Service Kit

The Harken Winch Service Kit contains commonly replaced parts such as pawls and springs, making annual servicing quicker and easier. It's worth having on hand before you start.

How to Service Harken Winches

The basic process is straightforward:

1. Remove the winch drum carefully.
2. Clean away old grease, salt, and dirt.
3. Inspect gears, bearings, pawls, and springs for wear.
4. Apply Harken Winch Grease to gears and bearings.
5. Lubricate the pawls with Harken Pawl Oil.
6. Reassemble and test the winch.

Q&A: Frequently Asked Questions About Servicing Harken Winches

Q: How often should I service my Harken winches?
A: Harken winches should generally be inspected and serviced at least once a year, especially on boats used regularly in saltwater or racing environments. More frequent servicing may be needed for heavily used winches.

Q: What are the signs that a Harken winch needs servicing?
A: Common signs include:

• The winch feels stiff or difficult to turn
• The drum does not spin smoothly
• Clicking sounds are irregular
• The pawls fail to engage properly
• The winch slips under load
• Excess grease or salt deposits are visible

Regular maintenance helps prevent poor performance and premature wear.

Q: What grease should I use on a Harken winch?
A: Use a marine winch grease designed for gears and bearings. Apply only a light coating to these areas. Avoid putting grease on pawls because it can restrict movement and prevent correct engagement.

Q: Should I grease Harken winch pawls?
A: No. Pawls should not be greased. They should be lubricated with a light pawl oil so they can move freely and engage correctly.

Q: Can I service my Harken winch myself?
A: Yes. Many sailors service their own manual Harken winches by removing, cleaning, inspecting, lubricating, and reinstalling the winch correctly. Take care with small components such as pawls and springs.

Q: How long does it take to service a Harken winch?
A: A basic service usually takes around 30 minutes to an hour per winch depending on the model, condition, and experience level. Older or neglected winches may take longer.

Q: What tools do I need to service a Harken winch?
A: Typical tools include:

• Screwdrivers
• Allen keys
• Clean rags
• Small brush
• Degreaser
• Harken Winch Grease
• Harken Pawl Oil
• Replacement pawls and springs if required

Q: What is the basic process for servicing a Harken winch?
A: The process involves removing the winch drum, cleaning old grease and salt deposits, inspecting gears, bearings, pawls and springs, applying the correct lubrication, then reassembling and testing the winch.

Q: Why is my Harken winch clicking but not working?
A: A Harken winch that clicks but does not grip may have dirty, damaged, or incorrectly lubricated pawls. Inspect the pawls and springs, clean them thoroughly, and replace worn parts if necessary.

Q: How do I lubricate a Harken winch?
A: Apply winch grease to gears and bearings only. Use light pawl oil on pawls to keep them moving freely. Avoid over-greasing, as excess lubricant can affect performance.

Q: What should I check during a Harken winch service?
A: During servicing, check:

• Gear teeth for wear
• Bearings for smooth operation
• Pawls for movement and damage
• Springs for correct tension
• Drum and spindle condition

Q: Can a poorly maintained Harken winch fail under load?
A: Yes. Dirt, salt buildup, worn pawls, or incorrect lubrication can reduce performance and cause a winch to slip or fail when under load. Regular servicing helps maintain safe operation.
