🔌 Function

The front balancer shaft carries an offset counterweight that produces an opposing vibration force as it rotates.

Working with the rear shaft, it reduces the second-order vibration naturally produced by an inline four-cylinder engine.

Common signs of wear or damage:

• Excessive engine vibration

• Rumbling or knocking noise

• Worn shaft journals

• Scored bearing surfaces

• Bent shaft

• Excessive end float

• Damaged driven pulley

• Balancer belt tracks incorrectly

• Metal particles in the oil

• Oil leakage around the balancer cover

Recommended checks before installation:

• Inspect every journal

• Measure shaft runout

• Check end float

• Inspect the pulley keyway and mounting surfaces

• Check the balancer belt and tensioner

• Inspect the case and bearing surfaces

• Replace associated seals and O-rings

• Align all balancer timing marks

• Rotate the engine manually before starting
