Land Rover Discovery: Joints and Joint Faces
All gaskets should be installed dry unless stated otherwise. Always apply the specified lubricant to O-rings and install 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. Make sure 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.
LOCKING DEVICES
Always replace locking devices with one of the same design and of the correct size.
TAB WASHERS
Always release locking tabs before loosening fixings, do not reuse tab washers.
LOCKNUTS
Always use a backing spanner when loosening and tightening locknuts, brake and fuel pipe unions.
ROLL PINS
Always install new roll pins of the correct size.
CIRCLIPS
Always install new circlips ensuring that they are of the correct size for the groove.
WOODRUFF KEYS
Woodruff keys may be reused provided there is no indication of wear or distortion.
Remove any burrs from edges of keyways using a fine file.
SPLIT PINS
Never attempt to straighten and reuse a split pin, always make sure that replacement pins are of the correct size for the hole in which they are to be installed.
