3) Precautions for reassembling the turbocharger onto the engine
For re-assembly of the turbocharger or handling it after re-assembly operation, be sure to observe the fol-
lowing precautions :
Especially, pay attention to prevent foreign matters from entering the inside of the turbocharger.
(1)
Lubricating system
●
Before reassembling the turbocharger onto the engine, inject new oil in the oil inlet port and lubri-
cate the journal and thrust bearings by rotating them with hand.
●
Clean not only the pipes installed between the engine and oil inlet port but also the oil outlet pipe
and check them for damage or foreign matters.
●
Assemble each joint on oil pipes securely to prevent oil leaks.
(2) Intake system
●
Check the inside of the intake system for foreign matters.
●
Assemble each joint on the intake duct and air cleaner securely to prevent air leaks.
(3) Exhaust system
●
Check the inside of the exhaust system for foreign matters.
●
Be sure to use heat resisting steel bolts and nuts. Do not interchange them with ordinary steel bolts
and nuts when performing re-assembly operation. Apply anti-seizure coating to the bolts and nuts.
