• The front balancer shaft is a separate component.

• Timing and balancer-belt alignment must be set correctly during installation.

  

🔌 Function

  

The balancer shafts rotate in a timed relationship with the crankshaft to counteract vibration generated by the inline four-cylinder engine.

  

The gear case and spacer support and locate the balancer-drive components within the powerhead.

  

Common signs of balancer-system wear:

  

• Abnormal engine vibration

• Rumbling or knocking from the front of the powerhead

• Balancer belt or gear noise

• Excessive shaft movement

• Worn shaft journals

• Damaged bearing surfaces

• Oil leakage around the balancer case

• Cracked or corroded gear case

• Incorrect balancer timing

• Metal debris in the engine oil

  

Recommended checks before installation:

  

• Inspect shaft journals and bearing surfaces

• Measure shaft runout

• Check balancer gears and pulleys

• Inspect the case for cracks or corrosion

• Replace O-rings and gaskets

• Inspect the balancer belt and tensioner

• Align crankshaft and balancer timing marks

• Rotate the engine manually before starting

• Verify oil pressure and vibration after installation
