Kawasaki STX 160 Jet Ski Crank Bearing Kit

Crankshaft bearings support the rotating assembly and help maintain smooth, dependable engine operation. As mileage and operating hours increase, these bearings can wear and develop excessive clearance. This crank bearing kit fits 2020-2026 Kawasaki STX 160 Jet Ski models and provides the bearings commonly replaced during a lower-end rebuild.

Because bearing condition directly affects crankshaft performance, inspect each bearing carefully during teardown. If you find roughness, discoloration, or excessive play, replace the bearings before reassembly.

What This Kit Includes

• Crankshaft Main Bearings
• Crankshaft Center Bearings
• Crankshaft Outer Bearings

When Should You Replace Crankshaft Bearings?

Every lower-end rebuild should include a thorough bearing inspection. However, if any bearing shows signs of wear or damage, replacement is the safest approach before returning the engine to service.

• Main bearings feel rough during rotation.
• Center or outer bearings show excessive wear.
• Bearing surfaces display heat discoloration or pitting.
• The crankshaft has already been removed for rebuilding.
• You’re rebuilding the engine for long-term reliability.
