Sealing The Camshaft Housing Sealing Face
NOTE:
-
Use only Loctite 574 to seal
-
Loctite 574 hardens only when contact with metal is made and air ingress is prevented.
-
After having applied the sealant, bolt up the crankcase sections within approximately 10 minutes since the sealant bead applied directly to the
metal surface will otherwise start to cure.
