the engine. See Figure 6. Note: No
gasket is used between the
turbocharger and manifold.
11.
Install a 3 ⁄ 8 " AN washer over the
six longer studs. Note: Due to casting
clearance, washers cannot be used on
the two shorter studs.
12.
Apply a small amount of anti-
seize onto the threads.
13.
Install a 3 ⁄
8
" collet-lock nut onto
each of the 8 studs with the round
collet side of the nut against the AN
washer and tighten to approximately
15 - 20 ft-lbs. Start the first nut on the
short stud of each turbo flange. Note:
This torque value is just for reference.
A torque wrench cannot be used to
tighten these studs due to the limited
clearance. The nuts must be tightened
with an end wrench. See
Figure 7.
14.
Loosen the six compressor and
six turbine housing bolts on each
turbocharger so the housing may be
rotated. Rotate the turbo center
sections so that each oil inlet flange
faces up. Note: The oil inlet port is
round and the oil drain port is square.
15.
Lay a straightedge on top of the
oil inlet flanges of the center sections.
16.
Rotate the center sections until
the top surface of each oil inlet flange
is flush with the straightedge. See
Figure 8.
17.
Tighten all six bolts that hold the
center section to the exhaust turbine
housing on each turbocharger to 12-15
ft-lbs. (For reference only, use an end
wrench)
18.
Bend over the lock tabs for each
of the bolts tightened. Note: Leave the
bolts that hold the compressor
housing to the center section loose
until later.
