Why Replace the Balance Shaft Assembly?
The balance shaft helps offset engine vibration created by moving internal components. Over time, bearings and balance shaft components can wear, which may contribute to excessive vibration, noise, or reduced engine performance.
Therefore, replacing worn balance shaft parts during an engine rebuild can help restore smoother operation and protect other bottom-end components.
Completing a Bottom-End Rebuild?
Many Polaris 800 engine rebuilds also include crankshaft, bearing, seal, and gasket replacement. If you’re planning a larger project, review our Engine Rebuild Kit Guide for additional rebuild options.
