Andersen 58ST & 62ST Self-Tailing Winches — Product Manual

Tools & Materials

• Allen keys 5 mm and 8 mm
• Ø10.5 mm (13/32") drill
• Bedding compound
• 6 × M10 (3/8") countersunk head screws and nuts
• 6 × large washers or a backing plate
• Ring spanner to match the nuts

Steps

1. Drill Ø10,5mm 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 (14) with 6 M10 (3/8") countersunk head screws, large washers or a backing plate.
5. Assemble in reverse order (note the curved spring "arm" when fitting the pawl springs).
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 quickly.

The tools list gives the drill as Ø10.5 mm (13/32") and step 1 as Ø10,5mm (3/8") – as printed.

Strip & Clean

• Tools: Allen keys 5 mm and 6 mm, small screwdriver, winch handle, ANDERSEN winch grease.

1. Remove screws (1), the self-tailing arm (2) and drum (4), then the drive shaft (5).
2. Clean the balls (8, 9) with a rag. Do NOT remove the balls or the small retaining ring (7) above them.
3. Remove screws (15), the upper base (10) and roller bearing (13).
4. Remove shafts (16), then remove and dismantle the two gear units (17), (18).
5. Clean all parts in white spirits / mineral spirits, including the gear teeth and the ball track inside the drum (4).
6. 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 rope entry shown in the manual, with the self-tailing arm within the shaded area.
• To identify the output drive gear: insert a winch handle and rotate in both directions; the drive gear only rotates clockwise, in a fast and a slow speed.

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.
