Service Kits Simple service kits are available to permit routine maintenance of Harken® winches. Kits are available with drum screws, pawls, and springs. Harken® winch grease is a non-aging, high-adhesive synthetic lubricant. It is resistant to both salt and fresh water and protects metal gears, roller bearings, and all moving winch parts from corrosion and wear. Note: Do not grease pawls, plastic rollers, or balls. Installation manuals and parts lists are available online at www.harken.com. To download, select the winch product category and scroll down to the “Service” section.
