FAQ

Q: How do I verify if this bolt fits my specific excavator engine?
A: The most reliable method is to check the part number on your existing bolt. It should read 8973296180 or 8-97329618-0. Additionally, confirm your engine model (e.g., 4HK1, 6HK1). If you have a Hitachi excavator, the engine model is typically stamped on a data plate on the engine block or valve cover.

Q: What is the correct installation procedure for this oil check bolt?
A: Installation is straightforward. First, ensure the old bolt and sealing washer are removed. Clean the mounting surface thoroughly. Apply a small amount of clean engine oil to the new bolt’s threads. Install the new bolt with the included sealing washer and tighten to the manufacturer’s specified torque (typically 20-30 Nm for similar bolts). Do not over-tighten, as this can damage the threads or the sealing surface. After installation, start the engine and check for leaks.

Q: What is the function of this bolt, and what happens if it fails?
A: This bolt is not a standard drain plug; it is a specialized component with an internal passage that allows a controlled amount of oil to flow to the valve train components. If it becomes clogged or fails, the valve train may not receive adequate lubrication, leading to rapid wear of camshafts, followers, and rocker arms. A stripped thread or a damaged sealing surface can also cause a significant oil leak, leading to low oil pressure and potential engine damage.
