Winch Maintenance and id

I am needing to take apart the attached winch to do maintance but have no idea what type of winch it is or how to disassemble. Any sugestions how to get it appart and what I should do to get it back in ship shape. Starting to grind a bit like it is dry or may have grit in it.

Re: Winch Maintenance and id

On closer examination today I was able to raise a name on the winch. It is Marinum. SO I have an ID but no idea how to disassemble it to grease it.

Re: Winch Maintenance and id

The end of the flat bladed winch handle should fit perfectly that horizontal slot you see when looking down into the winch. Using it like a huge screwdriver, you should be able to unscrew. Then the outer body will lift off. The prawl pushers/springs are usually contained, but you want to go nice and slow and maybe drape some towels around to catch anything that does manage to ping off.

Great to Hear. I tried that Earlier but didn't move it and not knowing was afraid I might do Damage. Now that I know I'll go back down to the boat and try a little more "persuasion." Any suggestions on what type of grease to use?

Ditto above suggestions.

I would spray some AeroKroil or PBblaster into the top and allow to soak in before loosening. WD40 should work but I prefer the others.

I also tape a cardboard box with a slightly oversize hole in the bottom over the winch to keep all the parts in one place.

Lewmar and Harken both make (repackage) grease for winches but ounce for ounce they're valued above gold. I would think just about any synthetic grease should work.

Re: Winch Maintenance and id

Took a little work but I got all the winches off and they are now in my shop soaking. The old grease was dry and caked but the gears all look good so probably just a good cleaning and repack them. When I have done winches in the past I always just grabbed what ever grease was lying around the shop so will probably do the same now. Any sailing stuff like specific grease I have to order in as there is nothing available locally (or within 1000km) so I try to find easily available alternatives. Thanks for the advice.

I recommend white lithium grease - I currently have a cup of Gunk brand that is good. You can get it at auto parts stores in a cup like a chip dip cup.

By the way, marinium is the material the winch drums are made of, not the manufacturer.

Don't pack with grease, just cover all surfaces. A small disposable 1" brush is helpful. Clean with mineral spirits, doesn't take much soaking. Be sure to use waterproof grease if not using the right stuff.

Re: Winch Maintenance and id

i have similar winches on my boat. Possibly, i will repeat, possibly they are Wilcox and Crittenden. They also used to make marine heads. You can google them, I think someone else is making parts.
