FAQ

Q1: Will this eccentric bearing bush fit my Cummins NH220 engine directly?
A: Yes, this part (157870 / 6610-21-1040) is manufactured to OEM size specifications for the Cummins NH220 engine. It is designed as a direct replacement. We recommend comparing the dimensions and part number against your old component to confirm fitment before installation.

Q2: What is the function of this eccentric bearing bush in the engine?
A: This bush supports the eccentric shaft, which is often part of the fuel injection pump or camshaft drive mechanism. It allows the shaft to rotate smoothly while handling offset loads. A worn bush can lead to timing errors, noise, or reduced engine performance, making timely replacement critical.

Q3: How should I install this part?
A: Installation should be performed by a qualified diesel mechanic. The bush is typically pressed into its housing. Ensure the bore and shaft are clean and properly lubricated during assembly. Always check the clearance against the shaft diameter. If you are unsure about the fit, please consult your engine’s service manual or contact our technical support for guidance.
