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.

 

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?

 

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

 

Thanks,

Bill
