How to remove the Harmonic Balancer in the 2.0L four cylinder engine on BMW 325i?

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).

BMW 325i Harmonic Balancer

The BMW 325i Harmonic Balancer keeps the straight-six running smoothly by soaking up the crankshaft's torsional shakes before they can cause damage. Sitting on the BMW crank snout, this Harmonic Balancer combines a steel hub, a rubber sandwich layer, and a heavy inertia ring that twist against each other so the rubber flexes and cancels vibration. Many versions on the 325i line include machined V-grooves so one unit can also spin the auxiliary belt, proving it is more than a simple pulley. Earlier E30 and E36 cars applied a plain dampening ring, while later 325i editions added integrated counterweights, allowing the Harmonic Balancer to help offset piston and rod mass for even finer balance, the main distinction between the two styles. Regardless of year, heat, oil, or salt can harden or soften the rubber, and once the layer loses elasticity the Harmonic Balancer can no longer track the frequency range tuned by BMW engineers, leading to rough running and potential crankshaft failure. Therefore every BMW 325i relies on a healthy Harmonic Balancer for lasting reliability.

How to remove the Harmonic Balancer in the 2.0L four cylinder engine on BMW 325i?

A:
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.
