Balancer Unit Gear for Engine Balance Shaft Systems SKU: QT31171741

When a balancer shaft gear fails or wears excessively, your engine develops noticeable vibration at idle and throughout the RPM range, causing operator fatigue and potentially damaging other engine components. This precision-cut replacement gear restores proper counterbalance function, bringing your engine back to smooth, vibration-free operation.

Why This Component Matters

• Precision-engineered tooth profile maintains exact timing with the balance shaft system
• Heat-treated construction resists wear under constant high-RPM operation
• Exact specifications ensure proper mesh with drive components for long service life
• Critical component that prevents costly engine damage from excessive vibration

A worn balancer gear creates problems that only get worse with time—rough idle, vibration through the operator platform, and accelerated wear on engine mounts and related components. Trust S&H Parts for the precision replacement your engine needs, backed by our 55 years of technical expertise.
