Thank you List,

Found excessive runout on the front driveshaft (engine-to-trans), this =
one is turning full-time whether the clutch is depressed or not.  Spent =
$30 at the machine shop and I am back in business.  Thanks to all who =
responded with real good comments.

Bill

When the clutch is depressed the rest of the drivetrain is out of the =
picture so everything points to the engine. =20

If one of the clutch cover bolts is missing the imbalance may be quite =
pronounced.  Let's hope it is something easy like that.

Subject: [TR] Strange Vibration

Not quite a TR but an older Morgan with the TR3A motor and Moss gearbox. =
 I have a vibration that I can feel all the time but really is strong at =
the 2500-3000rpm range.  With the clutch in it is still there, when =
driving it is worse.  Drive shaft is straight and balanced, makes no =
difference with the wheels removed.  Have pulled the front pulley and =
put a gauge on the crank end, no wobble.  Engine mounts are tight.

=20

Prior to installation I ran the motor without a driveline extensively =
just in the chassis and all was good, is it possible for a clutch plate =
to be off-balance so much as to cause a noticeable vibration?

=20

Just fishing for any suggestions before I pull the motor and recheck the =
flywheel/clutch assembly.

=20

Thanks,

Bill
