FAQ

Q: How do I confirm this rocker arm assembly fits my Caterpillar 3306 engine?
A: Please check the casting number or part number on your existing rocker arm assembly. If it matches 8N4576, 2P6526, or 7N8026, this assembly is a direct replacement. Additionally, ensure your engine is a 3306 model (e.g., 3306B, 3306C, or NA/TA variants).

Q: Is this a complete assembly, or do I need to order other parts?
A: This is a complete rocker arm assembly, ready to install. However, during installation, we recommend inspecting the pushrods, valve bridges, and camshaft lobes for wear. Replacing the valve cover gasket is also a best practice.

Q: What is the recommended maintenance after installing this part?
A: After installation, perform a valve lash adjustment according to the Caterpillar 3306 service manual. Check the torque specifications for the rocker arm base bolts. We also recommend an initial oil change after the first 50 hours of operation to remove any break-in particles.
