Reliable engine performance starts with precision-engineered small parts. If you are maintaining a heavy-duty fleet, the 140330 (also known as 140-330) bushing is a critical component for ensuring the longevity of your Caterpillar 3306 or 3304 series engines. As a professional supplier, we provide OEM-standard replacements that meet the rigorous demands of construction and industrial applications.
This Part Number 140330 is specifically designed for the small end of the connecting rod, providing the necessary bearing surface for the piston pin. Accurate fitment prevents premature wear and engine knocking.
