I plan on using the original stock type discs in my transmission. Last night in disassembling the transmission, I was very pleased to find the lug shoes (26/27 trans) in very good shape, no visible wear. The discs have some discoloring from oil deposits around the edges, and other than some very light scoring on some, look real good. Is there any reason not to clean them up, and reuse them, or should they all be replaced, as the car is disassembled now.
If they're not warped, burned, or cracked, run 'em!
You can see plenty of good clutch disks at swap meets that are perfectly good ones. They were usually replaced because some people just wanted 'new ones'.
I have a bucket full of good ones I picked for practically nothing just because they need a little clean up.
Maybe a very few were cracked or worn to any extent that I found.
I went back to the original discs after using good and bad turbo 400's, they are smoother in change from low to high and on a car that is approaching 89 - 107 years old, that's gotta be a kind thing to do.
The down side is when it's cold - hmmm the starter motor suffers - in my case its my arm.
Doug, like David, I am running original discs, and did nothing more that what you have done to clean them up and use. Like Brian above...run 'em !!! I have an aux tranny with neutral, and an elec starter, so starting is not a problem when cold...I used to jack the rear wheel when cold on my first resto a few years back.
Thanks for the encouragement. I just could not see dropping another $100 if I did not have to.
Doug, just clean up the plates and re-install them. I would use a new clutch spring.
I am lucking out. I paid $250 for the entire transmission, and so far it appears I will not need to do anything to it. I pulled it apart last night to confirm it was a good as I expected. I have not mic'd the bushings yet, but they feel real good. The drums are all great. And yes I planned on a new spring. It is already in my cart at Langs. As soon as I determine which ball cap I need I can pull the trigger and order
Doug, I would also sand blast the drums and carefully look for cracks which are very common.
Doug, usually the trans shaft will be worn at a taper where it goes through the ball cap, you will most likely have to have it trued up then determine what cap to order and have it bored to fit. KGB
