I had a similar problem when I first mated a T-96 to my 4.6L. The crank was from a 74 258 with auto trans. But mine wouldn't disengage! Turns out the pilot hole on the later engine isn't quite as deep as the one on the 63 196 the trans came from. I trimmed about 1/8" off the end of the input shaft with a cut-off wheel, tapered it with a grinder, and it worked great. I'm wondering if maybe the pilot hole in your crank is deep enough that the clutch will disengage, but shallow enough to put a bit of pressure on the end of the input shaft? I'd think there would be some signs of heat and/or rubbing on the end if that's the case though. Just a thought... ------------- Date: Mon, 08 Sep 2008 16:21:04 -0700 From: Tom Jennings <tomj@xxxxxxx>\ Nahh, it's a HARD failure. The clutch shaft has a taper on the inside end, to hold the friction ring, making a cone. That cone was peened over from rotating jammed against the mainshaft! The friction ring (the brass thing with 5-sided teeth that does the early synchro engagement) had to be pried off. I don't really understand the failure. The snapring was a bit loose, but come on, it wasn't THAT! loose! I'm not (that kind of) idiot! Short of dropping the trans on it's nose, I don't understand how the snapring came off in the first place, or if THAT was a symptom of some weird assembly error or component problem. I assume I screwed up somewhere -- this trans operated, and fit just fine, before I started. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
