If you get a Hz reading of say 134, you know the vibration is occuring at 8000RPM or twice every crank rotation if your are revving the motor to 4000RPM and holding it there. Generally, if it happens in the first order, look at your rotating assembly (flywheel, crank, pistons/rods and balancer). If it happens at the half order (or less) look at your valvetrain. If it happens at the second order good luck, it can be a ton of things. Read up on vibration analysis in machinery for more on this. Hope that helps! |
yeah that defiantly gives me something to try. thanks.
are you 100% you ruled out the motor by putting on the sr bell housing? it sound like your tests of clutch in/out dont point towards the trans. Just trying to make sure you dont overlook anything.
just wondering: how high does your mount system hold the trans? I heard they hang below the frame rail with kits on the market
