Tools and Materials You’ll Need
- Screwdrivers (flathead and Phillips)

Step-by-Step Guide to Servicing Your Harken Winch
1. Prepare Your Work Area
Ensure you have a clean, organized workspace. Lay down a towel or non-slip surface to prevent losing small parts.
2. Disassemble the Winch
- Remove the drum screws or top cap (varies by model).
- Carefully lift the drum off, keeping an eye on any loose parts.
- Take note of how the components fit together for easy reassembly.
3. Clean the Parts
- Use a degreaser or mineral spirits to remove old grease and grime.
- Scrub gears, pawls, and bearings with a small brush.
- Rinse with clean water and dry thoroughly.
4. Inspect for Wear and Damage
Check gears and bearings for signs of wear or corrosion. Inspect pawls and springs—replace them if they look worn out.
5. Lubricate the Components
- Apply a light coat of Harken winch grease to gears and bearings.
- Use only a minimal amount—too much grease can attract dirt.
- Apply a few drops of light oil to the pawls (avoid grease, as it can cause sticking).
6. Reassemble the Winch
- Carefully reinsert all components in the correct order.
- Secure the drum and tighten any fasteners.
- Double-check that all parts move freely.
7. Test the Winch
- Rotate the handle to ensure smooth operation.
- Listen for any unusual noises.
- Wipe off any excess grease.
Maintenance Schedule and Tips
- Frequent Use: Service every 2–3 months.
- Occasional Use: Service at least once a year.
- After Heavy Use: If sailing in rough or salty conditions, clean and lubricate more often.

Frequently Asked Questions
How often should I service my Harken winch if I use it frequently?
Frequent-use winches require servicing every 2–3 months. Additionally, if you sail in rough or salty conditions, you should clean and lubricate the winch even more often after heavy use. Regular servicing prevents salt, grime, and old grease from reducing efficiency or causing potential failures.
What type of lubricant should I use on Harken winch pawls?
Pawls require a few drops of light oil specifically — grease must be avoided on pawls because it can cause sticking. For gears and bearings, apply a light coat of Harken winch grease, using only a minimal amount, as excess grease attracts dirt and debris.
What tools do I need to service a Harken winch?
Servicing a Harken winch requires flathead and Phillips screwdrivers, Allen wrenches for some models, winch grease, degreaser or mineral spirits, clean rags, paper towels, and a small brush such as an old toothbrush. Replacement pawls and springs should also be on hand if needed.
How should I clean Harken winch components during servicing?
Degreaser or mineral spirits are used to remove old grease and grime from winch parts. Scrub gears, pawls, and bearings thoroughly with a small brush, then rinse with clean water and dry all components completely before proceeding to inspection and lubrication steps.
What should I inspect for when servicing a Harken winch?
During servicing, gears and bearings must be checked for signs of wear or corrosion. Pawls and springs also require close inspection and should be replaced if they appear worn out. After reassembly, rotate the handle and listen for unusual noises to confirm smooth operation.
