How to Remove the Harmonic Balancer in a VR6

A VR6 engine is a family of six-cylinder engines that Volkswagen developed in the late 1980s. It appears in a variety of Volkswagen cars, such as the 1992 Passat. The VR6 engine uses a harmonic balancer, also known as a vibration damper, on the crankshaft to minimize the vibrations that occur when the crankshaft turns rapidly. A central bolt attaches the vibration damper in this engine directly to the crankshaft. You will typically remove the vibration damper to gain access to the crankshaft seal.

Instructions

1

Record the security code for the radio so that you can connect the battery after removing the harmonic balancer. Disconnect the cable from the negative battery terminal with a socket wrench. This prevents you from inadvertently starting the engine, while removing the harmonic balancer.

2

Remove the splash shield for the front wheel wells with a socket wrench to gain access to the vibration damper. Some vehicles with a VR6 engine also require you to disconnect the lower engine shield to access the vibration damper.

3

Hold the crankshaft pulley in place with Tool No. 3273. Detach the accessory drive belt that the crankshaft drives.

4

Disconnect the central bolt on the crankshaft with a socket wrench. Remove the vibration damper from the crankshaft.
