[T3] motor vibration.

[Dave Hall]

Hi Ross,
The clutch components, and very likely the flywheel too, have balancing
holes or dimples drilled.  Where they exist (or there are paint marks) the
recommendation is that they are fitted opposite. 

It's also possible to get vibrations due to imbalanced carbs.  Once the
air-flow through the induction system is greater, this tends to disappear as
the balance hoses can cross-feed to some extent.

If it's a rattling noise rather than a vibration, check the cover plates and
muffler insulating plates are all firmly fixed. 

A long screwdriver or rod held to the ear may help narrow down where the
vibrations are coming from.

Subject: [T3] motor vibration.

Hello to all,

I have a 1966 type 3 fastback with twin carbs. Recently I replaced the heads
with new units. Once the motor was out I also replaced the clutch plate,
pressure plate, throw out bearing. I have now noticed a motor vibration when
the car reaches 1200 to 1500 RPM when the car is stationary. The vibration
does not seem to appear while driving. My gut feeling is a worn cooling fan
bush running out of true when revs are increased!  I am not experienced in
this cooling fan arrangement as I have only owned beetles and kombis before
I restored this fastback.

Can anyone suggest a probable cause of this vibration. Should it be the fan
are they easy to replace and does the motor have to be taken out of the car
to complete the replacement? Any advice would be helpful.

Regards,
