Lewmar winches maintenance kits & maintenance accessories

Depending on the Lewmar series and winch size, there are standard service kits for regular maintenance (e.g., pawls & springs, seals/O-rings, stripper components) as well as repair/spare part packages for wear on bearings or mechanical components. For electric winches, additional components (e.g., motor/electrical parts) are included depending on the model. The key factor is always: a kit that matches the Lewmar winch series (not “just any universal part”).

Identify the manufacturer (Lewmar), size, and series—usually via the embossing or nameplate on the drum or base. A photo from above (drum/top) and a photo of the base, as well as a part number if available, are also helpful. This usually allows you to clearly identify the correct Lewmar kit. Tip: If the old part has already been removed, also document the dimensions and shape of the end piece (e.g., pawl).

Racing/training (high load cycles, frequent winching): regular quick checks during the season (smooth operation, pawl behavior) and a thorough maintenance at least once per season. Cruising: annual maintenance during winter storage or at the start of the season is usually sufficient. Professional use/charter: check and document more frequently depending on usage intensity. If any abnormalities are noticed (creaking, cleats not engaging properly, stiffness), always act promptly to prevent further damage.

The main items checked are pawl/springs (clean engagement), bearings (roughness/play), stripper components, seals, and gears for edge/pitting wear. Typical wear parts include pawls/springs, bearings, O-rings, and stripper rings. If these are replaced in a timely manner, the mechanism remains precise and the winch runs more smoothly—especially important on dinghies/catamarans with frequent maneuvering and on yachts under load.

Yes—many sailors maintain their Lewmar winches themselves if they follow a systematic approach. Document each step (with photos), lay out parts in order, and secure small parts to prevent loss. Use genuine Lewmar replacement parts and appropriate care/lubrication products. If you suspect damage to load-bearing components (gears, drum, housing) or if the winch is used in a safety-critical capacity in commercial shipping, it is advisable to have it serviced by a specialist.

The most common mistake is using too much grease—it attracts dirt and can cause the pawl to jam. Clean thoroughly, dry all parts, and then lubricate selectively: Never grease the pawls; instead, lightly oil them so they engage freely. Apply grease sparingly to bearing and gear areas. After reassembly, check that all parts move freely before the winch is loaded.

In most cases, repair is worthwhile because wear parts and many components can be replaced individually, and this is usually significantly cheaper than a new winch. A complete replacement makes more sense if load-bearing components are severely damaged (e.g., drum, main gears, housing) or if corrosion/material erosion compromises the structure.

A clean parts tray, brushes/cloths, a suitable cleaner, winch grease, and light oil for cleats, plus the appropriate tools (screwdrivers/circlip pliers depending on the model) have proven useful. For onboard maintenance, small spare kits (cleats/springs) are practical for quick repairs during regattas or on long voyages.
