FAQ

Q1: How do I confirm these valves (1152368/1152367) fit my specific 3406B engine?

While these part numbers are the standard OEM specification for the 3406B engine, we recommend verifying your engine’s specific arrangement number (e.g., 5LG, 4CK, 7LG, 2YG) or Serial Number (S/N). Cross-referencing your old part number with our listing is the most reliable method to ensure a correct fit. If you are unsure, please contact our support team with your engine details.

Q2: What is the recommended installation procedure for these valves?

Installation should be performed by a qualified diesel mechanic. The process typically involves removing the cylinder head, cleaning the valve guides, applying assembly lube to the valve stems, and inserting the valves. It is critical to check and adjust the valve lash (clearance) according to the Caterpillar 3406B service manual after installation to prevent engine damage. Always use new valve stem seals during installation.

Q3: What is the typical lifespan of these aftermarket valves compared to OEM?

When installed correctly and with proper engine maintenance (clean fuel, good oil, and regular air filter changes), these valves can provide a service life comparable to OEM parts. The 6-month warranty covers manufacturing defects. The actual lifespan will depend on the engine’s operating conditions, load factors, and overall maintenance schedule. Regular inspection of the valve train is recommended for heavy-use applications.
