Multiquip 12251ZF6W00 Gasket Cylinder Head GX-390HC-3713005 - OEM Replacement Part

This cylinder head gasket creates a critical seal between the engine block and cylinder head on GX-390HC engines, preventing combustion gases, oil, and coolant from leaking while maintaining proper compression. A failing head gasket can cause difficult starting, loss of power, oil contamination, or engine overheating—all symptoms that require immediate replacement to prevent catastrophic engine damage.

This genuine OEM gasket is engineered specifically for the GX-390HC-3713005 engine used in Multiquip concrete and asphalt saws. Proper installation requires clean, flat mating surfaces and adherence to manufacturer torque specifications. The manual warns against tipping the engine to extreme angles during operation or transport, as oil can gravitate into the cylinder head area, potentially compromising gasket integrity and making the engine difficult to start. Regular inspection of this gasket during scheduled maintenance intervals helps ensure reliable performance in demanding cutting applications.

Compatible with the following Multiquip models:

• CD6CE13H18 Stow Cutter 1 CE Saw
• SP118
