Општи преглед компоненти (Дисцовери 3)

All components should be inspected for wear or damage before reassembling.

• Always ensure that component to be inspected is clean and free from oil or grease.
• When a component is to be checked dimensionally against design specified values, use the appropriate measuring equipment i.e. micrometers, verniers, surface plates, dial test indicators (DTI).
• Always ensure that all measuring equipment is correctly calibrated before use.
• Reject a component which is not within specified values/limits or if it appears to be damaged.
• A component may be refitted if dimensions obtained during checking are at the maximum tolerance limit and it is in an undamaged condition.
• Bearing journal clearances should be checked where necessary using Plastigage.

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.

ПАЖЊА: 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.

ПАЖЊА: 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.
