What is the purpose of a wrist pin bushing?

The wrist pin bushing sits inside the small end of the connecting rod. It provides a smooth bearing surface for the piston's wrist pin to pivot within, allowing the piston to move freely while maintaining critical clearances.

What does 'Prop 65' mean for this part?

California's Proposition 65 requires businesses to provide warnings about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. This warning indicates the product contains a chemical that falls under that regulation.

Do I need any special tools to install this bushing?

Installing a wrist pin bushing typically requires specialized tools for pressing the old bushing out and the new one in without damaging the connecting rod. It's recommended to consult the manufacturer's installation instructions or a professional mechanic for proper installation.
