Installation Guide
Difficulty
Hard
Est. Time
2 hr 0 min
Tools Required
- bearing puller/installer
- torque wrench
- socket set
- crankshaft holding tool
- micrometer for measurement
Pro Tips
- Freeze the new bearing overnight and heat the case to 250°F for easy press fit
- Apply assembly lube to bearing surfaces
- Check crankshaft runout after installation
Common Mistakes to Avoid
- Not preheating case for bearing installation
- Installing bearing backwards
- Insufficient case cleaning leading to premature failure
Comparison vs Stock/OEM
Direct OEM replacement dimensions and quality equivalent to Honda/Kawasaki/Suzuki genuine parts
Improvements
- Often more affordable than OEM
- Same Japanese bearing quality
- Rubber seals provide better protection
Considerations
- Always OEM-equivalent - no performance upgrade over stock
Durability & Warranty
Expected Lifespan
Same as OEM - 100-300 hours depending on maintenance and riding conditions
Warranty
1 year manufacturer defect warranty
Maintenance
Inspect during every top-end service. Replace during bottom-end rebuild (every 100-200 hours hard riding)
