FAQ

Q: How do I confirm if this rocker arm (3069020) will fit my engine?
A: This part is designed specifically for the Cummins QSM11 engine model. Before purchasing, please verify your engine’s serial number and the existing rocker arm part number. While it is an OEM-size replacement, checking the physical dimensions and arm geometry against your old part is the best practice for fitment confirmation.

Q: What is the recommended installation procedure for this rocker arm?
A: Installation should be performed by a qualified diesel mechanic. The process generally involves removing the valve cover, loosening the rocker arm shaft bolts, and replacing the assembly. It is critical to follow the engine manufacturer’s service manual for the correct torque specifications and valve lash adjustment to prevent engine damage.

Q: Can this rocker arm be used as a single replacement, or should I replace the entire set?
A: While it is technically possible to replace a single rocker arm, it is often recommended to inspect the entire rocker arm shaft assembly and valve train components. For optimal performance and even wear, replacing the rocker arms in pairs or as a full set on the same shaft is advised. This helps maintain consistent valve timing and lift across all cylinders.
