(2) Rotor radial play
(3) If the measured axial and radial plays are beyond the limit of wear, replace or repair the
turbocharger.
3) Guide for disassembling/cleaning and checking the turbocharger
First, disassemble the turbocharger from the engine and clean/check it with the oil inlet and
outlet plugged with tape and so on.
4) Precautions for reassembling the tarbocharger onto the engine
For reassembly of the turbocharger or handling it after reassembly operation, be sure to
observe the following precautions:
Especially, exercise extreme care 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 lubricate 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.
