103 ENGINE2.2LDICOR turbochargers concerned must be returned even if turbo does not show any visible signs of damage to Honeywell so that the components can be checked, in particular the condition of actuator calibration, condition of flanges, etc., l During quality inspection, follow the instructions of handling. l After the inspection, replace the caps or other protect ive devices inorder to avoid the introduction of foreign objects. Preparation for assembly on engine l Ensure the conditions of handling and installation of turbocharger / manifold are such that there is no risk of shocks, dropping the turbocharger or damage to the sealing surfaces (turbine housing inlet and outlet surfaces, compressor inlet nad outlet , oil circuit), or damage to the actuator or flow adjusting rod and screw which might lead to the misalignment l Check, before connection, that the internal piping of the manifolds and / or upstream turbine piping and sealing surfaces are free of particles as well as the oil inlet piping on the turbocharger. It is recommended that the cleanliness standards for the internal surfaces of the turbine housing of turbo be applied to the exhaust manifolds inorder to limit the risks. l The tightening of the oil inlet piping and the connections must be done inline with the suppliers recommendations as indicated in the turbocharger drawing. Tightening torques not specified in the drawing must be in line with tightening standards relating to component definitions. l Before each connection is made, ensure that any protective caps have been removed. l Do not handle the engine unit using the turbocharger (the compressor outlet, the actuator, its support, housing, control rod, heat shield or the oil inlet or return pipes) as a handle l During transport of engine after assembly inside the plant, use protective caps for all open ends to ensure there are no foreign objects Preparation for engine tests l Ensure the engine is mounted very close that it will have on vehicle inorder to guarantee the oil supply and return. l Before the test, ensure any protective caps have been removed. l During the tests, the 'provisional' connections of turbo must be such that the stress imposed on the casings are negligible l General lubr icat ion precaut ions for the turbocharger (filtering, oil pressures on starting, time taken for the rise in pressure are followed as per turbocharger outline drawing) are followed. l Protect turbo against introduction of impurities when filling oil during engine start. Engine start / green engine l Protect turbo from introduction of impurities when filling oil l Before engine is started, it is preferable to fill few drops of oil at turbo l The starting of a green engine must be done with a progressive in the speed of the engine in order to allow the oil pressure to establish itself in the oil inlet piping and in the turbocharger's internal oil circuit. l A starting strategy which maintains a low turbocharger speed is recommended, to give the oil pressure time to establish itself before starting to rotate the turbo at high speeds. Please look at turbocharger outline drawing for minimum oil pressure requirement
