4. Turbocharger
(See Figures 1 and 2.)
A. Removal
(1) Remove the engine cowling. (Refer to 71-10-00.)
(2) Remove the turbocharger by the following procedure:
(a) At the center section of the turbocharger, remove four (4) bolts and washers (2 each, top
and bottom) and disconnect the oil line (top) and oil drain tank (bottom). Remove bolt and
washers securing oil drain tank support bracket to turbine housing.
(b) Remove hose clamps and disconnect the air ducts from the compressor inlet and outlet.
(c) Remove four (4) bolts, nuts, and washers and disconnect the exhaust transition pipe from
the turbine inlet.
CA
UTION
: IF LOCKWIRE ON V-BAND COUPLING IS FOUND BROKEN, CLOSELY
INSPECT V-BAND T-BOLT FOR STRETCHING, CRACKING, OR OTHER
DAMAGE BEFORE REUSING THAT V-BAND COUPLING.
CA
UTION: WHEN REMOVING OR INSTALLING V-BAND COUPLINGS, SLIDE
COUPLING OVER THE END OF THE PIPE BEFORE ASSEMBLY/
DISASSEMBLY. EXCESSIVE SPREADING CAN LEAD TO PREMATURE
COUPLING FAILURE.
(d) Remove V-band coupling and disconnect the tailpipe at the turbine outlet.
(e) Remove two (2) bolts and washers that attach the turbine to the mounting bracket and
remove the turbocharger.
B. Installation
(1) Immediately prior to mounting the unit, prime the lubrication system as follows:
(a) Invert turbocharger and fill center housing with new clean oil through oil drain.
(b) Turn rotating assembly by hand to coat bearings and thrust washer with oil.
(c) Coat threads of attaching bolts or studs with high temperature thread lubricant.
NOTE: If the turbocharger is to be installed on a new or newly overhauled engine,
operate the engine with a separate oil filter in the oil supply line to the
turbocharger during the first hour of operation. This must be done to ensure that
no metal particles are carried from the engine into the turbocharger lubrication
system.
(2) Position the turbocharger in the mounting bracket and secure the mounting bracket to the
turbine housing with two (2) bolts and washers.
(3) Align transition pipe with the turbine inlet and secure with four (4) bolts, nuts, and washers.
(4) Position the tailpipe at the turbine outlet and secure with V-band coupling as follows:
CAUTION: IF LOCKWIRE ON V-BAND COUPLING IS FOUND BROKEN, CLOSELY
INSPECT V-BAND T-BOLT FOR STRETCHING, CRACKING, OR OTHER
DAMAGE BEFORE REUSING THAT V-BAND COUPLING.
CAUTION: WHEN REMOVING OR INSTALLING V-BAND COUPLINGS, SLIDE COUPLING
OVER THE END OF THE PIPE BEFORE ASSEMBLY/DISASSEMBLY.
EXCESSIVE SPREADING CAN LEAD TO PREMATURE COUPLING FAILURE.
Install V-band coupling and while tightening the coupling nut, gently tap around the periphery
of the coupling with a soft mallet while shaking the tailpipe. This will distribute the band
tensions evenly. Continue tightening the coupling nut until a torque of 40-50 inch pounds is
reached on the turbine to tailpipe coupling. Secure with lockwire (see Figure 4).
