FAQ

Q1: Will this rocker arm assembly fit my Doosan DE08 engine used in a Daewoo excavator?
A: Yes, this part number 65.04200-6025e is specifically designed for the Doosan DE08 engine platform, which is commonly used in Daewoo/Doosan excavators and loaders. However, we always recommend verifying your engine model number and comparing the physical part with the provided OEM dimensions to ensure a perfect match.

Q2: What is included in the “Rocker Arm Assembly”? Does it come with the shaft, bolts, or bushings?
A: The product is sold as an individual rocker arm assembly. It typically includes the rocker arm itself and may include the pivot ball or bushing pre-installed. It does not usually include the full rocker arm shaft, springs, or mounting bolts unless specified. Please refer to the product images or contact us for a detailed list of included components.

Q3: How should I install this rocker arm to ensure proper valve lash adjustment?
A: Installation requires mechanical expertise. After installing the rocker arm, you must adjust the valve clearance (lash) according to the Doosan D1146/DE08 service manual specifications. Always use a feeler gauge to set the correct clearance between the rocker arm tip and the valve stem. Incorrect adjustment can lead to poor engine performance or damage. We recommend consulting a certified diesel technician for installation.
