[s-cars] Replaced heater blower fan - the new fan vibrates.....why?

[Fred Munro]

Chris;

If your new fan came with a black plastic sleeve over the motor, you
probably have a fan for the Type 44 cars. The UrS fan does not have a sleeve
over the motor and has a completely different fan wheel design. Check the
part number stamped on the new fan to make sure you have the right part.
Some fans have a balance clip, some don't depending on how far out of
balance the wheel is.

Well I am not too concerned about the plastic sleeve...I should have
tested mine before bolting everything backdown...bummer.

I beleive my fan is out of balance, you say yours had a balancing clip
on it? hmm mine didnt have any, makes me wonder.


I guess I'll find out after I swap the fans again.

Thanks
Chris
