FAQ

Q: How can I confirm this C6121ZG19B con rod bush fits my engine?
A: This bushing is specifically designed for the Shang Chai C6121ZG19B diesel engine. To confirm fitment, please check your engine model plate or parts manual. If your engine is a different variant of the C6121 series (e.g., C6121ZG18B), please contact us with your engine serial number for cross-verification.

Q: What is the installation process for a con rod bush?
A: Installation requires precision. The old bushing must be pressed out and the new one pressed in using a suitable arbor press. After installation, the inner diameter must be honed or reamed to achieve the correct clearance with the piston pin (typically 0.03-0.08mm for diesel engines). We recommend professional installation by a qualified diesel mechanic.

Q: How do I maintain the con rod bush for long service life?
A: Proper lubrication is critical. Ensure your engine oil is changed at recommended intervals and use the correct oil grade. Avoid prolonged operation under extreme loads or overheating conditions. During major overhauls, always inspect the bushing for scoring, galling, or excessive wear, and replace it if the clearance exceeds the service limit specified in your engine manual.
