FAQ
Q: Is this gasket set a direct fit for my Doosan D70S-7 forklift with a D34 engine? A: Yes, part number 4006dl03ohgk-4 is specifically designed for the Doosan Daewoo D34 engine family, which powers the D70S-7 forklift model. However, we always recommend verifying your engine serial number and comparing the gasket configurations (especially the head gasket bore size and thickness) against your original set to ensure a perfect match.
Q: What is included in this “Full Head Gasket Set”? A: This kit typically includes all gaskets required for a top-end overhaul: cylinder head gasket, intake and exhaust manifold gaskets, valve cover gasket, and various seals for the timing cover, water outlet, and fuel injection pump mounting. It does not include seals for the bottom end (crankshaft, oil pan). Please consult the included packing list for the exact contents.
Q: What installation precautions should I take with this gasket set? A: For optimal sealing, ensure the cylinder head and engine block surfaces are perfectly clean, flat, and free of any old gasket material or scoring. Follow the manufacturer’s specified torque sequence and angle-tightening procedure for the D34 engine. We recommend replacing the cylinder head bolts (not included) as they can stretch over time. Allow the engine to reach operating temperature, then re-torque the head bolts after the initial heat cycle if specified by your service manual.
