Installation and maintenance tips

• Clean sealing surfaces: Before installation, make sure that the sealing surfaces on the cylinder base and the engine case are completely clean, grease-free, and free of old gasket residues.

• No additional sealing compound needed: Aluminum gaskets already provide excellent fit. The use of additional sealing compounds is usually not necessary and can narrow the transfer ports.

• Even tightening: Tighten the cylinder head nuts diagonally with the recommended torque to avoid warping or uneven pressing of the gasket.
