Andersen 52ST Self-Tailing Winch — Product Manual

Tools & Materials

• Allen keys 4 mm, 5 mm and 6 mm
• Ø8.5 mm (11/32") drill
• 6 × M8 (5/16") bolts and nuts
• 6 × large washers or a backing plate
• Ring spanner to match the nuts
• Bedding compound

Steps

1. Drill Ø8,5mm (11/32") bolt holes using the winch template; keep drilling dust away from the winch.
2. Remove screws (1), the self-tailing arm (2) and drum (4).
3. Apply a light coat of bedding compound so that each bolt hole is bedded; keep the drain grooves clear.
4. Fasten the lower base (21) with 6 M8 (5/16") bolts, large washers or a backing plate.
5. Assemble in reverse order.
6. Check: the drum turns smoothly clockwise by hand and will not turn anti-clockwise; turning the handle clockwise the drum turns slowly, anti-clockwise it turns fast.

The step text calls the lower base item (21); in the parts list item 21 is the deckplate – as printed.

Strip & Clean

• Tools: Allen keys 4 mm and 5 mm, small screwdriver, winch handle, ANDERSEN winch grease.

1. Remove screws (1), the self-tailing arm (2) and drum (4).
2. Remove screws (12) and the upper base (8); dismantle it in a safe, comfortable place.
3. Remove the drive shaft (5) with a finger or a winch handle.
4. Release the roller bearing (6) by gently inserting a small screwdriver between bearing and base plate (8).
5. Remove shafts (15.7, 16.7), then remove and dismantle the two gear units.
6. Clean all parts in benzine, including the gear teeth, roller bearing track and the bushing inside the drum (4).
7. Assemble in reverse order, lightly greasing gear teeth, drive shaft, roller bearing, shafts, pawls, springs and bushings with a small soft brush. Pawls get only a very thin film of ANDERSEN WINCH GREASE.

General Information

• Normal use: dismantle, clean and lubricate the winch once every second year. Extensive use (racing, charter, blue water sailing): lubricate once every year.
• Use ANDERSEN WINCH GREASE (a silicone/Teflon grease). Most other greases, including "marine grease", are not suitable for winches and can cause malfunction.
• Replace the pawl arm springs every second year; spare arm springs and other parts are in the Andersen Service Kit for your winch.
• Remove the winch handle when it is not in use but the winch is under load.
• Only use the recommended line sizes in the self-tailer. With mooring lines, do NOT use the self-tailing function and keep the line clear of the self-tailing arm.
• Place the winch according to the ideal line entry shown in the manual; the self-tailing arm can be placed in several positions after installation.

When assembling, push each pawl against its spring: it must move smoothly and return by itself to engage the teeth. If not, clean and lubricate pawls and gears and check again; if they still do not work, replace the springs and recheck. Malfunctioning pawls may lead to unexpected release of the winch force.
