Strip Down Anchor Winch - Externals

The first service on the winch was a bit daunting and the manuals don't really give a good account of how to go about this. After a bit of investigating, I came up with the following.

Periodically... (And there's a question in itself. I have heard once a year, once every 3 months, and once a month. I think I'll go quarterly.) Periodically, dismantle the above-deck parts, clean thoroughly and apply a small amount of Marine Grade teflon grease to all bearing surfaces and reassemble - thus says the manual.

The above-deck parts.

Drop a winch handle into the clutch-nut, turn anti-clockwise and remove.

With the clutch-nut out, the drum assembly (inc. washer) can be pulled off vertically.

Unscrew the chain stripper. As you can see, I had a bit of a problem with this. Some penetrating oil and a little urging with an impact driver solved that problem. On reassembly, I will replace the screws with new and smear some anti-seize grease around them.

Once the chain stripper is off, the gypsy and distance piece can be pulled off.

The gypsy pawl just pulls out. The gypsy carrier / main shaft assembly can be raised by about 2cm. To completely remove the gearbox needs to be dropped from inside the boat.


It should be possible to clean out below the gypsy carrier with a brush & solvent before smearing grease around the shaft. The other parts can be cleaned and grease as well. Assembly is the reverse of the sequence, above.
