MAINTENANCE OF THE M88A1 - OD1672 - LESSON 2/TASK 1
Step 5.
Install a serviceable horizontal air intake hose in the reverse
order of removal of the unserviceable hose.
Step 6. Reinstall the air intake duct on the right side of the engine in
the reverse order of removal.
Step 7.
Coordinate with the supporting IDS unit, arranging for them to
reinstall the APU in the vehicle.
e. Exhaust System. Listed below is an example of the correct procedure
unit
maintenance
personnel
would
follow
for
the
troubleshooting,
maintenance, adjustment, and repair of this system, specifically: SMOKE
BEING BLOWN OUT OF THE ENGINE COMPARTMENT BY THE COOLING FANS.
(1) Troubleshooting.
During this troubleshooting process, unit
maintenance personnel would open the exhaust deflector doors (11 through 15)
(figure 9 on page 28) and inside deck doors to inspect the exhaust outlets
and exhaust pipes for damage or restrictions.
As a result of this
inspection, unit maintenance personnel find that the left exhaust pipe is
badly punctured, permitting the exhaust gases to be pulled into the engine
compartment by the cooling fans.
This exhaust pipe will have to be
replaced.
The following maintenance, adjustment, and repair procedures
describe the replacement of this exhaust pipe.
It is assumed that the
engine deck has been removed. This procedure, therefore, will describe only
the removal of the defective pipe and installation of a serviceable exhaust
pipe.
(2) Maintenance, Adjustment, and Repair.
Step 1. To permit access for the removal of the damaged left exhaust pipe,
the transmission breather (figure 27, view A, on the following page) and
crankcase breather tubes (figure 27, view B) must be removed.
Steps 2
through 4 describe the removal of these two tubes.
Step 2.
To provide access, the powerplant (engine and transmission) must
first be removed. Here, it is assumed that the powerplant has been removed
and only the removal of the transmission breather tube will be discussed.
Before removing the transmission breather tube, remove two bolts, two nuts,
and two cotter pins from the throttle rod (figure 27, view A), and then
remove the throttle rod itself.
