Andersen sailing winches have a strong record for service and support. However, after 60 years of product evolution, it can sometimes be difficult to keep track of which of Andersen winch service kit is required for each of the winch models. In this blog we provide a comprehensive quick reference guide on identifying the correct spare parts for your Andersen winches.
Andersen Winch Service Kit Range
Andersen winch service kits are numbered 1, 2, 3, 4 ..... etc and there are approximately 30 different kits. They contain the crucial spare parts for regular maintenance, which is generally replacement pawls & springs, bearings, circlips and essential screws. However, the parts in each kit are specific to each type/size of winch and also vary depending on the age of the winch. Some sizes of Andersens winches have been remodelled 2-4 times and each version can require a different service kit. Therefore it is important to know which Andersen winch you have!
Identifying your sailing winch
Before buying any spare parts or winch service kit it is essential that you know the size/model, year of manufacture and version number. The winch size is clearly visible and stamped on the top of the winch e.g. 46 is size 46. Then it is important to know if you have either a Self-tailing or a Classic winch: If your size 46 winch has a self tailing arm, Andersen refers to this as a 46ST and all plain-top winches are referred to as the Classic range.
Self-Tailing Winch
Classic (Plain-Top) Winch
Andersen have consistently stamped the serial number information on the top side of the deck flange, between the mounting bolt holes, which is clearly visible when you lift off the polished stainless drum (N.B. on very old winches, a similar stamp was placed on the bottom side of the flange).
The format is always the same for serial numbers: Year, Month and version number (YY-MM-Vxx). For the Electric and Hydraulic motor units a serial number starting with “PS” is stamped on the top flange of the gearbox housing.
