| vibration in 427 |
| By joe schepker - 08/28/2002 8:44:06 PM; IP 152.163.188.231 |
| well, to make a long story short, i have a 64 427 in a 66 GT fairlane with a 4 speed. it has about 1,000 miles on it. it developed a BAD vibration at about 2500rpm and goes away at about 3500. it was glass smooth until about a week ago. the clutch wasn't feeling quite right either(pedal is about an inch lower than it used to be and sometimes stayed down until i stomped on it). it was also getting harder to shift. it's a 12" replacement diafragm style that had hard use on the 390 that was previously in the car. i thought i'd start there and when i pulled the cover off, i found a silver streak in the cover about 3 inches long, like someone took a pencil and drew a line in the grease(or asbestos) that wasn't there 1,000 miles ago. (only in one side of the cover though.) i also noticed fine silvery particles in there. i turned it over while looking at it and also noticed that the throwout bearing was wobbling back and forth as the motor turned while it was against the pressureplate fingers . looking at the flywheel, i noticed that on one side only i could see about 1/16" to an 1/8" around the outside of the disc where it looks like it polished the flywheel. but NOT on the other side. seems to me that the disc is walking. would this small amount of clutch walk cause the vibe that i'm describing? would that indicate a bad bearing in the trans? it feels just like a 428 flywheel was there instead. the assembly was balanced and the vibe wasn't there before. it just showed. any ideas? the past week, the tranny did make some noise at the top of 1st when you nailed it(a growling sound) that it didn't before. thanks, joe |
