• Confirm which shafts, gears, case, spacer, bearings and pulleys are actually included.
• The front balancer shaft is a separate component.
• Timing and balancer-belt alignment must be set correctly during installation.

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.

• 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

🛠️ Service Notes

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
