Peter, Paul and Balliol

Success! 3 days marinading in diesel and light lube oil (about 50:1) and all the shafts freed. Now all working sweetly.

Not so successful getting aluminium rope drum off main shaft; in spite of soaking, heating and pulling ( with puller), only succeeded in taking a bight out of the rim of the drum. But because of freeing the main shaft, I don't really need to remove the drum, and may just make a cosmetic repair since I intend to use the winch for chain.

Thank you all, for your tips - I shall keep the exotic additives (coconut oil and ATF) in reserve for serious cases!

Thanks Paul - diesel, coconut oil and a dash of ATF it is! Thanks all of your tips. I'll report back the outcome.

On USA vintage car forum I have seen recommendations for a mix of diesel and ATF ( automatic transmission fluid).

Thank you very much, Paul. I'll use diesel mixed with a bit of oil.

Can I suggest that you don't use any spirit based liquid, such as white spirit, or even WD40, a good oil based penetrating fluid, or diesel mixed with fine oil, or coconut oil will penetrate if given enough time to work, apply liberally, immersion if possible as Balliol suggested. Once free use a few drops of fine oil such as 3 in 1 for lubrication.

Thank you very much for your reply. I am trying to avoid a full strip down, but I will try the soak in diesel. It might free up the main bearing, even if it doesn't help with getting the drum off. Thanks a lot.

Not sure if you are intending to strip and rebuild the unit completely, but it is certainly worth trying to lubricate the bearings. I have never known Tufnol to swell measurably, and it is frequently used within oil bath gear cases, and/or otherwise lubricated. If intending to strip my inclination would be to marinate the whole thing upside down in a tub of diesel for a few days, then try the pullers again.

I have just obtained a rather elderly Seatiger, a two speed manual winch. All functioning, but the main bearing is very stiff- almost seized. The bearings are made of Tuffnol and I can only get to them if I can get the aluminium winch drum, off the steel shaft. This has defied all efforts with a puller and heat and WD40. So my questions are (a) any more ideas for removing the drum? and (b) if I cant remove the drum would lubricating the bearings with penetrating oil, or even white spirit, help, or would it cause the Tuffnol to swell up further and make the problem worse?

I would be very grateful for any suggestion.

PS I have attached the Seatiger instructions which contains a very good exploded view, showing the tuffnol bearings and the winch drum
