How to Adjust Valves on a 12 Valve Cummins: A Step-by-Step Guide

Adjusting the valves on a 12 valve Cummins engine is a relatively simple process that can be completed in a few steps. It is important to note that this process should only be done when the engine is cold.

Step 1: Remove the valve cover. To do this, use a socket wrench to remove the bolts that hold the valve cover in place. Once the bolts are removed, carefully lift the valve cover off the engine.

Step 2: Locate the valves. The valves are located on the top of the engine and are easily identifiable by their shape.

Step 3: Adjust the valves. Using a feeler gauge, measure the gap between the valve stem and the rocker arm. If the gap is too large, use a wrench to turn the adjusting screw until the gap is within the manufacturer’s specifications.

Step 4: Reinstall the valve cover. Once the valves have been adjusted, replace the valve cover and secure it with the bolts.

Step 5: Start the engine. After the valve cover has been reinstalled, start the engine and check for any leaks. If there are no leaks, the valves have been successfully adjusted.

Adjusting the valves on a 12 valve Cummins engine is a relatively simple process that can be completed in a few steps. Following these steps will ensure that the valves are adjusted correctly and that the engine runs smoothly.
