How to remove the Harmonic Balancer in the 2.0L four cylinder engine on BMW 330i?

Raise the front of the vehicle and support it securely on jackstands. Release the fasteners and remove the engine splash shield where installed. Remove the drivebelt(s). Prevent the crankshaft from turning using special tool# 11 8180 or 22 2 742 (or equivalent) that locks against the flywheel. Remove the six mounting bolts, and remove the harmonic balancer/pulley. Do not remove the crankshaft center bolt; if the center bolt is loosened or removed, the timing chain and oil pump sprockets will lose contact with the crankshaft, which will allow the intake and exhaust camshafts to turn independently of the crankshaft and severe engine damage will occur. Install the balancer mounting bolts and tighten the bolts to the torque. Again, hold the pulley if necessary when tightening the bolts. Install the drivebelt(s). Where applicable, install the engine splash shield.

BMW 330i Harmonic Balancer

The BMW 330i Harmonic Balancer prevents destructive crankshaft shake by absorbing torsional vibrations and keeping the inline six running smooth. Mounted at the crankshaft nose, the Harmonic Balancer sandwiches a rubber ring between a solid hub and an outer inertia ring. The rubber flexes so the outer mass moves out of phase with twisting forces and cancels them. Many versions for the BMW 330i carry V-grooves on their rim to drive belts, letting the Harmonic Balancer handle both damping and component rotation in one piece. Some units add small counterweights that partner with factory crankshaft weights, further balancing piston and rod mass during every power stroke. Over the years, BMW retained the same basic rubber bonded layout for each 330i generation, though later cars use tougher elastomer compounds to resist heat, oil, and road salt. When the rubber degrades, the Harmonic Balancer loses flexibility, vibration rises, and the crankshaft risks fatigue. Inspecting this Harmonic Balancer periodically keeps any BMW 330i running reliably.
