Is there anyone there who can tell me >Why a Sonata 2000 2.4lts .When
repacing the timing belt the instruction included on the Hyundai Web Site
mention that the oil pump Sprocket to be also timed.Thanks

 

The oil pump sprocket is attached via gear drive to a balance shaft. If
it
isn't timed properly, you'll get an engine vibration.

 

Thanks a lot for the answer.Harstat

 

So if it happens to be a few teeth off and you have an engine vibration, any
harm done to the engine? (speaking hypothetically here)

Probably not, but it'll be very annoying when you drive the car. By the
same token, the vibration will be felt in the entire car. I'd suppose
that some items attached to the engine could experience vibration fatigue.
