Maintenance & Replacement:
Gaskets should be replaced whenever components are removed for service or repair. Never reuse old gaskets as they compress and lose their sealing ability once installed. Always replace gaskets during routine maintenance, repairs, or component replacement to ensure proper sealing and prevent leaks.
Installation Tips:
Clean all mating surfaces thoroughly before installing the new gasket. Remove all traces of old gasket material and ensure surfaces are clean, dry, and free of oil. Install the gasket dry unless your service manual specifies otherwise. Torque bolts to manufacturer specifications in the proper sequence to ensure even compression and a leak-free seal.
Compatibility:
Verify this part number matches your engine's requirements before ordering. Consult your Yanmar engine manual or parts diagram for your specific model, or contact technical support if you need assistance confirming compatibility.
