CHAPTER 4
16. Place the clamp band over the flange on the turbine
housing. Position the core assembly in the turbine
housing aligning all reference marks.
IMPORTANT:
Make
sure
the mating
surfaces
are
clean and
free
of burrs
to
prevent possible misalign-
ment
and damaged blades.
17. Coat the threads of the clamp band bolt and the flat
face of the clamp band nut w Ith graphite grease.
Make sure the band Is properly positioned to catch
the flanges of both housings. Install the nut and
tighten it to a torque of 120 lbs. in. (1,380 kgm).
18. Apply graphite grease lightly around the machined
flange of the compressor cover to ease positioning
the cover when the turbocharger is completely
assembled.
IMPORTANT:
Make
sure the
mating
surfaces
are
free
of
burrs
to prevent possible blade damage,
19. Position the compressor cover on the bearing hous-
ing aligning the reference marks as shown in Figure
12.
20. Secure the compressor cover to the bearing housing
with the eight bolts, lock was he rs, and the four
c lall1) plates. Tighten the b o Its diagonally to a
torque of 60 lbs. In. (.990 kgm).
21. Spin the turbine wheel. The compressor wheel and
the turbine wheel should rotate freely. If a drag is
felt, remove the compressor cover arid the turbine
hous Ing to determine the problem area. If necessary,
completely disassemble the unit and inspect all parts
again. Reassemble and recheck.
E. Installation
Before installing the turbocharger on the tractor, the
following checks must be made and corrected if neces-
sary:
• Check the exhaust and air intake systems for leaks,
and remove any loose, foreign, or deteriorating
material.
• Clean the air cleaner element.
Foreign material can quickly damage the turbocharger
blades and destroy the precise balance of the rotating
components. Exhaust and air intake leaks or restrictions
will cause a reduction in the air supply to the engine and
result in high exhaust temperatures.
1. lnstal I the oi I return tube and gasket on the turbo-
charger.
2. Position a new gasket and the turbocharger on the
manifold, Figure 13, at the same time locating the
oil return tube on the cylinder block adapter. Secure
the turbocharger with the four nuts and lock washers
and tighten the nuts to a torque of 30-35 lbs. ft.
(4.15-4.84 kgm).
3. Add an ample supply of clean engine oil to the turbo-
charger through the oi I i n take
port
to thoroughly
lubricate the turbocharger.
