FAQ
Q1: Is this rocker arm a direct bolt-on replacement for my Cummins KTA19 engine? A: Yes, this part (3418858) is manufactured to OEM specifications and is designed as a direct replacement for the stock rocker arm on the KTA19 engine. However, we always recommend comparing the dimensions and part number with your original component to confirm compatibility, especially if your engine has undergone previous modifications.
Q2: What tools are required for installation? A: Installation typically requires standard hand tools, including a torque wrench, socket set, and feeler gauges for valve lash adjustment. You will need to remove the valve cover, rocker shaft, and existing rocker arms. We recommend consulting the official Cummins KTA19 service manual for exact torque specifications and adjustment procedures to ensure proper valve clearance.
Q3: How can I verify the quality of the rocker arm before installation? A: We provide a Machinery Test Report with each order, confirming critical dimensional checks. Additionally, we can offer video outgoing inspection footage upon request. Before installation, visually inspect the rocker arm for any surface defects, ensure the pivot bore is smooth, and confirm the pad surface that contacts the valve stem is free from wear or damage.
