Turbocharger Lubrication
1.
Beating
3. To Sump
2. From Pump
The oi I acts as a heat barrier between the hot turbin'
and the compressor, lubricates the bearings, and aids
the removal of excess heat.
The high speed at which the turbine wheel and com•
pressor wheel revolve, and the high temperature of the
exhaust gasses, require the turbocharger to receive an
adequate supply of clean quality oil, ade<µiate clean air,
and the full pressure of the exhaust gasses.
CAUTION: To
avoid personal
injury
and prevent flangt
warp, allow the exhaust manilold to coo/ sulfic:ientl,
after
the
tractor engine
has
been r~m before attemptin5
to service the turbocharger.

TURBOCHARGER OVERHAUL
A. Removal
1. Remove both hood side panels and the exhaust exten-
sion (muffler) from the tractor.
2. Remove the exhaust pipe by removing the four bolts
from the exhaust flange, Figure 3.
3. Remove the three bolts that secure the exhaust flange
to the manifold and remove the flange and seal ring.
4. Disconnect the air cleaner-to-turbocharger tube and
the turbocharger-to-fotake manifold tube, Figure 3,
from the compressor side of the turbocharger by
loosening the clamps securing the tubes to the turbo-
charger.
5. Remove the oi I supply tube and disconnect the oil
return tube from the cylinder block. Cap the ends of
the tubes and the openings to prevent foreign material
from entering the system.
IMPORTANT: Dirt or other foreign material that may
enter the
lubrication
system
will seriously damage
the
turbocharger and/or
engine components. Take
care to prevent
dirt entry into
the system ..
