Precautions for refitting operations
l Tighten nuts and screws to the specified tightening torques. l When refitting flexible pipes and cables, take care not to twist or tangle them. l Always fit new seals, O-rings, split pins, and safety stop rings; make sure that the ends of the cotter pins are separated and bent back so that the pin cannot be withdrawn from the hole. l Ensure that circlips are correctly installed in their seatings. l When applying the thread-locking compound, first clean the part to remove all oil and grease, then cover the thread evenly applying a few drops of the compound.
l When applying sealant, first clean the surface removing all traces of oil and grease, and check for dirt or indentations, then apply the sealant evenly making sure that it forms a continuous film around any fixing holes. l Clean all parts, removing dirt, oxidization, carbon deposits, burrs, and indentations.
l Coat all moving parts with a thin film of engine oil. l When reconnecting electrical wiring connectors, first remove all traces of oil, dust, and water from the inside of the connector
and then push the two halves together firmly; connectors with locking tabs should be pushed together until the tab engages
the keeper. l Bolt down flanged fittings evenly, tightening the screws gradually in a crosswise pattern.
