Default Hudson Wet Clutch Replaced With Dry Clutch

This's one of two Hudson questions I'm posting; originally on AACA, I was unable to get onto the HET Club forums...
Back in our jalopy days (early 1950s??) we had a 1936 6cyl 4dr, probably the cheapest model as it was painfully plain inside; not knowing it had a wet clutch, we may've let fluid leak out, and clutch went out...
An ex hot rodder ran a wrecking yard, where we bought all our parts; he refused to replace the wet clutch, but offered to try to fit a dry clutch, for no charge, if we would let him play with it...
He did, in fact, fit a dry clutch, I assume from his inventory, but swore he'd never do another; the clutch worked fine as long as the car ran...
QUESTION: Was this unusual for older jalopy Hudsons/Terrapieces?? At the time we assumed it was more or less normal...

I have had Hudson made cars for decades & have never seen a dry clutch conversion. Even today converting one would be pointless. The wet clutch actually is very smooth & positive in its operation. The original setup works very well but you must make sure the oil does not leak out. ATF will work if you cannot find the correct "Hudsonite" oil. The clutch disc has dozens of holes in it with a cork plug in each hole. If the oil is gone the cork will burn out.


You can reline the cork clutch plate yourself if you are careful. First you need to drink a lot of wine --------

We recently acquired a 46 Hudson, and this is an issue that we will have to look into before I try to run it. The motor is loose and nice and clean. May have been reconditioned before the car was retired in the 70s. Gonna take a bit of training for me to learn about the critter! Anyone have a picture of said clutch ? Trying to get an idea of how it looks.

As I remember standing in front looking at the flywheel housing , on the drivers side there is a access hole. turn the flywheel till you see the plug in the flywheel. this is the fill hole and oil level. The clutch bolts on the flywheel with gasket like the first GM torque converters did , through out bearing has seals to keep the oil in as it moves. In the mid 50's they changed to a dry clutch.

Here is a poor picture of a cork clutch. The cover & spring arrangement are sealed & there is a gasket between it & the flywheel.

Ive considered the replacement idea. Anything can be done if you are determined. but... The biggest problem nowadays is the throwout bearing which has a leather seal like a pump leather. If that's good, fill 'er up with atf and go. My Uncle used to use a mixture of mineral oil and kerosene. But I don't know the recipe.

Many thxx to all for replies...
All these years I'd assumed converting to a dry clutch wasn't unusual...whatever Ted used came out of his wrecking yard inventory.
The only specific thing I can recall him saying about it was that it was frustrating getting the washers just right for spacing, apparently requiring removing the assembly several times to add or remove washers
