Reassembly Grease all removable parts when reassembling them . Position the circlips in the bearing housing so that the openings in them are facing towards the oil outlet . Mount the packing ring on the turbine shaft . Turn the opening in the ring so that it is facing towards the oil intake . Position the heat shield on the bearing casing, and then place the turbine axle in the bearing housing . Mount the bushing on the turbine shaft . Grease in the compresor bearing with engine oil, and mount it on the bearing casing, using new screws and washers to fasten it . The torque should be 1 .3 Nm±0 .1 .
Tighten the screws to the above torque, then loosen them a quarter turn before tightening them up to the correct torque again . Position the two packing rings on the oil deflector . NOTE : The opening in the inner ring should be facing the oil outlet, that in the outer ring should be facing the oil intake . Position the oil deflector in the cover . Smear the edges of the bearing housing which come in touch with the cover, using Permatex for the purpose . Bearing Housing Check the housing for corrosion or cracks . Check The thickness of the sealant should be about 0 .1-0 .2 mm . Fitthe cover on the bearing housing, and fasten itwith new screws and washers . The torque should be 1 .3 Nm±0 .1 .
