    So I’m told my 00’ is externally balanced by local auto part stores, I haven’t pulled the motor yet, but upon looking at my harmonic balancer and pulley it looks nothing like what it shows in store and online. Do I have a internally balanced motor? Also the car is a 5 speed don’t know if that info is pertinent.

    Any help appreciated

    Can't really tell with that picture. Take a look at the back side of that balancer. If it looks even all the way around with no obvious recessed section then it should be a neutral balance balancer meaning your motor is internally balanced.

    If there is an obvious recess in the balancer then your motor is externally balanced.

    I don't have pics on my phone but there are certainly pictures floating around of the difference I'm talking about.

    Much appreciated help guys, thanks. I’m safely guna say I have an internally balanced engine, I went to where I keep the car after work today (only have about 1 hr a day during the week to work, look at, clean the car) and grabbed this pic from under the car looking up.

    There are four balancers for the 2000.
    One is the externally balanced one, shown above.
    The other three three internally balanced ones, and I don't think it matters which one of those you use, as they all are balanced to zero counterweight.
    Just use the same casting or part number.
    1999 and early 2000 have the counterweight.
    Here is a list, with casting numbers...

    That first pic shows it is an aftermarket under-drive pullet.

    It looks long because the pulley is the same diameter as the balance ring!

    The very first post, is an externally balanced balancer, with a underdrive pulley.
    See how the pulley is the same diameter (+ or -) as the balancer.

    I get what you were saying but if it were externally balanced, would there not be a protruding weighted piece on the balancer? which there isn't.. its completely uniform on both sides.

    I never mentioned the length of it, as that has nothing to do with balancing.. When I said "biggest" I was referring to the width of the Pulleys Diameter.. I can already tell were guna be good friends going back and forth lol

    That is an externally balanced one.
    It has more material on one side than the other.
    The weight is on the balancer, not the pulley.
    Both balanced and unbalanced assemblies, have the same pulley.

    Like I said way earlier in the post I don't see the counterweight on my Harmonic balancer, so this kid has an underdrive pulley bolted to the oem balancer, which im safely saying is an internally balanced motor. Are we on the same page now, forgive my ignorance

    Use the number cast into the balancer.
    I posted the light blue chart above.

    Underdrive pulley has nothing to do with the balance.
    It is for making it easier for the motor to turn the accessories.
    The issue you brought up is this an externally balanced engine, which it Evidently is not.
    Use the chart I posted, and match the balancer to the old one.
    There is one external, and three internal.
    The last one is for a 4.6, as in the list of balancers available.

    Im curious as to which picture pete is looking at because the first picture edward posted it is impossible to discern what type of balancer it is.

    The second picture shows a better angle, not a great angle but youre able to see that its a neutral balance balancer.

    How is this still a discussion?
