FAQ

Q1: How do I know if this N14 Con Rod Bush will fit my engine?
A: This bushing is designed for the Cummins N14 engine platform. To confirm fitment, you should measure your original bushing’s inside diameter (ID) and outside diameter (OD) and compare them to OEM specifications. Alternatively, check your existing part number against the OEM cross-reference list. If you have the connecting rod part number, we can also verify compatibility.

Q2: What is the installation procedure for this con rod bushing?
A: Installation should be performed by a qualified diesel mechanic. The bushing is typically pressed into the connecting rod small end using a hydraulic press and a proper-sized mandrel. After installation, it is critical to hone or ream the bushing to achieve the correct piston pin clearance (typically 0.0015″ to 0.0035″ for N14 engines). Always follow the engine manufacturer’s service manual for torque specs and clearance values.

Q3: Is this part a direct OEM replacement, and does it include the piston pin?
A: This is a high-quality aftermarket replacement part, not an OEM Cummins part, but it is made to OEM dimensional standards. This listing is for the con rod bushing only. The piston pin and connecting rod are not included. You will need to purchase them separately if required for your rebuild.
