Joints and Joint Faces

Joints and Joint Faces
All gaskets should be fitted dry unless stated otherwise. Always fit new 'O' rings when reassembling components, always apply the specified lubricant to 'O' rings and fit 'O' rings using the fingers only.

Use gasket removal spray and/or plastic scrapers to remove traces of old gasket.

CAUTION: DO NOT use metal scrapers or emery cloth as these may damage the sealing surfaces.

Many joints use sealants instead of gaskets as the sealing medium. Where this is the case, the sealant together with its part number will be found listed in the relevant repair operation and also in the sealants table.

CAUTION: Always remove all traces of the old sealant prior to reassembly. Use plastic scrapers, specified solvents where available or dry, lint free cloth. DO NOT use metal scrapers or emery cloth as these may damage the sealing surfaces. Ensure that sealing surfaces are free from oil or grease as sealants will not adhere properly to contaminated surfaces.

Do not allow sealant to enter tapped holes or oilways.
