Does anybody know the torque specs for vibration dampener and rods and mains? 7fb 3406. I put new exhaust on it, and seemed loud this week. Not really exhaust loud, just generally loud. Seemed a little funny at certain rpms. It always had a few little shakes, nothing big, it is a 1986, not going to be like new. Anyway, was checking it over with the engine running, and sure enough dampener is wobbling. Looked at it, and yes the rubber is pushing out and the metal is shiny. So I turned down my load for Monday morning and as long as I'm doing the dampener, I'm going to drop the pan and check bearings. The guy I used to pull for had a manual, but he can't find it. I'm going to order one, but need one now.


Good catch!!
