  Note
t  The supercharger air system should not leak
t  The hose connections and the hoses for the charge air system must be free of oil and grease before the assembly.
t  Apply a silicon-free grease for rubber on the sealing surface and the oil seal. Any grease containing silicon or oil may not be used.
t  Replace damaged oil seals.
t  Insert the oil seal into the groove of the air charging hose and see that the groove is contact on the entire periphery, so that it is not damaged.
t  Secure all hose connections with the correct hose clips (same as original equipment) → Spare parts catalogue.
t  For a secure attachment of the charge air pipes to their connections, an anti-corrosive spray must be applied to the bolt thread in used clips before the assembly.
