ENGINE VIBRATION

[jreyes]

I HAVE A TROUBLE WITH MY 1972 FORD STRAIGHT SIX 240 ENGINE AND C4 TRANY.......IT SEEMS THAT TRUCK VIBRATES ONLY WHEN I AM IN A STOP LIGHT OR SIGN BECAUSE WHEN ITS RUNNING NO VIBRATION OCCUR.......SO I WAS WOUNDERING IF ANYONE HAS THIS TROUBLE OR HAD WILL LIKE TO HELP A FRIEND........

FOR THE RECORD THE TRUCK HAS NEW:
HARMONIC BALANCER
FUEL PUMP
STARTER
BELL HOUSING
DISTRIBUTOR
ENGINE MOUNTS
AND SOME EXTRA MORE THINGS........

maybe the balancer slipped off of the keyway. or the balancer is bad. when did this start happening? maybe its out of time just enought o make it shake. maybe it has a bad motor mount or its loose.

Uhm, you caps lock is stuck there.
How's the tune up? Pay money at a good shop to get a cylinder balance done, see if all the cylinders are even.

Do you have a vibration or a miss at idle? Could you explain in a little more detail what you mean by vibration? Many people use these two terms interchangeably, they are not the same.

Usually vibrations become worse as rpm increases. Vibrations are usually caused by mechanical failures. ( balancer, broken crankshaft, clutch out of balance) A miss although it could be mechanical is usually electrical in nature and except for an extreme miss will be more noticeable at low RPM's like when you are idling at a stop sign with your truck in gear.
