INSPECTION
1.
Perform turbocharger axial clearance check as follows:
a.
Loosen hose clamp screws and remove intake and exhaust pipes from turbocharger. Install dial depth gage as
shown and push rotor assembly away from gage.
b.
Set gage to zero.
c.
Push rotor assembly toward gage and record reading.
d.
Recorded reading must be 0.0015 to 0.0035 in. (0.038 to 0.089 mm). If axial clearance reading is not within speci-
fied range, replace turbocharger.
AXIAL CLEARANCE CHECK
2.
Perform turbocharger radial bearing clearance check as follows:
a.
Loosen hose clamp screws and remove intake and exhaust pipes from turbocharger.
b.
Push compressor wheel toward compressor housing. Measure clearance with gage and record reading.
c.
Push compressor wheel away from housing. Measure clearance, in same location, with gage and record reading.
d.
Subtract smaller clearance from larger clearance to obtain radial bearing clearance reading. Radial bearing clear-
ance must be 0.006 to 0.025 in. (0.152 to 0.635 mm). If reading is not within specified range, replace turbocharger.
