Rare problem with my 48 DeSoto clutch.

[MarcDeSoto]

The other day, I told my handy man to help me remove the clutch in my 48 Desoto.  He misunderstood what bolts I wanted him to remove, so he started to wrench on the three clutch release lever nuts.  I read the manual which says that to adjust the clutch release levers, you need to use Fixture C-585-A, which I don't have.  Since incorrect lever adjustment can cause a dragging clutch, I want to fix this problem before I install the clutch.  Is there a way to make sure the levers are set correctly without the fixture, or should I take the clutch to a clutch shop?

He sure messed up that clutch cover.

It will either have to set up by a clutch builder or get another one to make sure it is right.

I can get a new clutch cover and pressure plate assembly from Bernbaum for $128 if I send him my core.  Or I can call a transmission shop and see if they can do it.  I wonder if there's a way to hook it up and try to adjust it with it on the car?  Maybe I could get the engine running and see if the clutch release works well when i push the clutch pedal down?  This would be without the trans installed.

You could try adjusting those adjusting nuts....but many road tests later...a big hassle I would think.

Or send it out to......Tennessee clutch..

Or to a local clutch rebuilder.

Any way to tell from rust buildup in the threads where they were before?

these are set up on a jig...and usually with known true ground surface on the plate....if you had your fly wheel off and surfaced and the cover plate was also truly flat...one could use the assembly with a fabricated plate properly centered and preloaded to adjust the clearance.  That will be a lot of IFs to contend with...and if you do not get it right...you will not be happy, chatter will more than not be the results of misaligned unit and early disc failure.  Suggest as others....get a newly built clutch and cover and while you at it, get the flywheel dressed....be sure it is ground and not turned.  Turning will not remove the hot spots...

I never thought of getting the flywheel dressed.  I have a 48 DeSoto with fluid drive, so it doesn't have a flywheel.  Just a FD driving plate.  Can you tell just by looking at it whether it needs dressing?  

I called AAMCO and they said they don't repair clutches, but referred me to Southland Clutch in National City.  I called them and they said they could adjust the release lever nuts for $35.  Then the name Southland Clutch rang a bell.  That's where I bought this clutch back in the early 1980s!  I think I just brought them my old clutch and they sold me a rebuilt one.  That sure is better than buying a new clutch housing for $128 plus shipping and tax.  Marc.

while it is basically the cart before the horse....the driving place is serving as the traditional fly wheel in regard to disc and pressure plate.....and as with any flywheel, check for out of round, hazing (cracks) on the surface and blue/black hot spots that is usually indicative of a high point.  As these are now heated (color change) these spots are hardened and not cleaned/clear if just turned as a resurface measure...they need be ground...

[MarcDeSoto]

I think my driving plate is fine.  No burn marks or cracks and they can't dress it anyway.  They only surface flywheels.

I took my clutch to Southland Clutch today in National City (San Diego).  They were very nice and adjusted the clutch release nuts in just ten minutes.  I bought this clutch there 40 years ago!  Nice to see that they are still in business!

I used to go to those guys when I was stationed in San Diego.
