FAQ

Q1: Is this rocker arm assembly a direct replacement for the OEM part 65.04200-6027?
Yes, this assembly is manufactured to match the exact dimensions and specifications of the original Doosan part. It includes the rocker arm, shaft, bushings, and necessary hardware for a direct bolt-on installation.

Q2: What are the common symptoms of a failing rocker arm on a DE12 engine?
Common signs include a ticking or tapping noise from the valve cover, reduced engine power, rough idling, and in severe cases, a misfire. If you notice these symptoms, inspect the rocker arm for excessive wear, scoring on the roller, or loose adjustment.

Q3: Do you recommend replacing the rocker arm shaft and bolts as well?
Yes, we recommend replacing the rocker arm shaft and all related hardware (bolts, washers) when installing a new rocker arm. This ensures proper alignment and prevents premature wear. If your order does not include these, please contact us for a complete kit.
