Guest roadmaster56 Posted September 28, 2012 Share Posted September 28, 2012 I'm replacing the clutch and various elements of the Fluid Drive unit in my 1948 Chrysler New Yorker 8 cylinder and I need some advice. History and questions:The carbon seal and the copper bellows (40-51 "1st style") are leaking and need to be replaced. The carbon is pitted and the bellows has a pinhole leak in it. I have been able to locate, but have not yet purchased, the "1st style" which I have heard is inferior to the "2nd style" (51 - ?). Will the "2nd style" fit my "1st style" Fluid Drive unit.Is the upgrade to the '2nd style" is worth the effort so far as reliability is concerned? I probably put about 2000 miles per year if even that.I was told that if I use the "2nd style" seal, I would have to get the large retaining coller nut, which on the "1st style", is soldered/glued to the accordian bellows assembly....is this correct? If so, does anyone have a source for BOTH the later carbon seal, sleeve AND the large retaning nut? Does anyone have a photo of the "2nd style" seal complete?Finally, how do I remove the front most bushing/bearing (the smaller one that supports the fluid coupling)? The chrysler manual shows an extraction tool, but I don't have one, and all other attempts have failed to remove it.ThanksDavid in Santa Cruz Link to comment Share on other sites More sharing options...
Ron42Dodge Posted October 22, 2012 Share Posted October 22, 2012 David,I tried to repair my fluid drive years ago. I found the correct seals but never got the fluid drive totally apart. I fell one step short.The only place that I found that could repair it (about 10 years ago) was Northwest Transmission Parts. They also had the seals in stock but they also allowed me to send mine in.I had to ship my fluid drive to them and they shipped it back a couple of weeks later. It has worked great since.I don't have their info in front of me so I searched on the web. I believe this is them.Northwest Transmission Parts. 13500 US Route 62 Winchester, Ohio 45697 Information Line: 937-442-2811 Fax Line: 937-442-6555. Good luck.Ronwww.northwesttransmissionparts.com<!-- google_ad_section_end --> Link to comment Share on other sites More sharing options...
