- 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.
ATENȚIE: NU folosiți raclete metalice sau pânză de smirghel deoarece acestea pot deteriora suprafețele de etanșare.
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.
AVERTISMENT: Îndepărtați întotdeauna toate urmele de etanșant vechi înainte de reasamblare. Folosiți raclete din plastic, solvenți specificați acolo unde sunt disponibili sau cârpă uscată, fără scame. NU folosiți raclete metalice sau pânză de smirghel deoarece acestea pot deteriora suprafețele de etanșare. Asigurați-vă că suprafețele de etanșare sunt lipsite de ulei sau grăsime, deoarece etanșanții nu vor adera în mod corespunzător la suprafețele contaminate.
Do not allow sealant to enter tapped holes or oilways.
