Deglaze a clutch question

ken1962

Hi guys,

In a 1936 terraplane my clutch tends to shudder. I've been reading up that perhaps I could try deglazing before taking the next option of a rebuild - question what is a good mixture I could flush it or soak it for a day before putting in some Hudson fluid. I drained it 500 miles ago and the fluid was clear so no cork particles - if the deglazing fails I'm thinking the throw out may be at fault. Cheers ken

Ken, first thing I would check is if the amount of clutch fluid is right, 1/3rd pint Automatic transmission oil Dexron 3.

Good idea to drain and refill.           Do not use any made ford Ford cars.

Thanks guys for your advise. Used kerro to flush the clutch and refilled with dextron 3. The clutch is the smoothest action I've ever had with the car since getting it - drives as smooth as my modern car yeah :-)

Your welcome Ken, happy it worked for you.

I'm curious about the warning not to use ATF meant for Ford automatics. I have heard that before but I can't imagine that it would have any effect on the cork inserts, but I suppose the Type F (and later versions) could have some friction modifiers that might make the clutch misbehave. The only seals involved are either leather or neoprene, neither of which are affected by common lubricants.  Does anyone really know for sure?

I'm tempted to use the Ford version at the next fluid change as an experiment. How bad could it be??

G'day Frank.
Many years ago after fitting a new clutch assembly to my Hudson,I used some ATF which I had on the shelf that I used for my wife's Ford Fairlane. I went out for a days run,and on my return home I attempted to reverse up my drive,which is not steep at all, anyway the clutch slipped so much that the car would not reverse up the drive, I left it parked in the street and let it cool down,after it cooled,not a problem,worked as it should.I believe the oil boils at a much lower temperature than the Dexron ATF.I drained and refilled with Dexron, never had a problem in over 25 years.maybe oils have changed over the years, but, I prefer to use the tried and tested Dexron rather than someone calls me after I have rebuilt their clutch for them and say they have the slipping problem.I have rebuilt Hudson clutches here in Australia for over 55 years,we don't use corks anymore ,we have Kevlar bonded on to the plate and grooves cut across the Kevlar.We had Dexron tested many years ago and is as close to Hudsonite as you can get. This is only my experience with Ford oils over Dexron.

How does the clutch operation differ between cork and Kevlar and both disc rebuild price?

No noticeable difference between cork or Kevlar,price wise ,don't know as we don't do corks,but,would imagine not much difference.Have not done corks in over 25 years.

Does using Kevlar require any other changes to the mechanism? I presume the Kevlar sandwich ends up the same thickness as the ones done with corks. Is my presumption correct?

Yes, the Kevlar sheet is the exact thickness of the corks.No other changes are necessary.

Huddy,

Is that to say that you used the F in a cork clutch and experienced a problem? If so, I wonder if it would behave similarly with the Kevlar facing or act OK. Maybe I'm just beating this to death......

Frank , by memory it would possibly have been a Kevlar lining, but, cannot say for sure as it was many many moons ago.
