To remove the harmonic balancer on a 1990 3L D21, first disconnect the negative battery terminal and remove any accessories that may obstruct access, such as the fan and radiator shrouds. Use a crankshaft pulley holder tool to prevent the crankshaft from rotating, then remove the center bolt using a socket and breaker bar. After loosening the bolt, use a harmonic balancer puller to gently extract the balancer from the crankshaft. Make sure to clean the crankshaft and inspect for any damage before installing a new balancer.
