7.23 Model 6036 Legacy
Engine: Cummins 4BT3.9
7.9 ENGINE EXHAUST SYSTEM
The exhaust system is supported by the engine and the
vehicle frame to help minimize the transfer of noise and
vibration into the operator’s cab. The tailpipe directs
exhaust fumes to the right side of the vehicle, away from
the cab.
Annoying rattles and noise vibrations in the exhaust
system are usually caused by the misalignment of parts.
When aligning the system, leave all capscrews and nuts
slightly loose until all parts are properly aligned, then
tighten all fasteners working from the front of the system
to the rear.
When replacing the muffler, also replace the tail pipe.
Before assembling components, use exhaust system
sealer at all slip joint connections.
When installing exhaust system components, allow
sufficient clearance between the components and other
vehicle pipes, hoses and wiring that could be adversely
affected by excessive heat.
When installing an exhaust system, provide for parts
expansion when the system is hot.
Whenever performing service on the vehicle, check the
condition of the exhaust system. Check the entire exhaust
system for broken, damaged, missing or improperly
aligned parts, open seams, holes, loose connections and
other deterioration which could permit exhaust fumes to
seep into the operator’s cab. Correct any damaged areas
immediately.
7.9.1 Exhaust System Removal
1. Level the vehicle, ground the attachment, place the
travel select lever in NEUTRAL (N) and engage the
neutral lock lever. Engage the parking brake switch
and shut off the engine.
2. Remove the ignition key. Secure accident prevention
tags to the steering wheel and ignition switch. (Refer
to Section 1.5, “Accident Prevention Tag Usage.”)
3. Unlock, unlatch and open the engine covers. Allow
the engine to cool before proceeding.
4. Disconnect the negative (-) battery cable (Fig. 7 -2, 1).
5. Disconnect and remove the V-band clamp
(Fig. 7 -25, 1) from the exhaust pipe (2).
6. Disconnect and remove the 3" U-type clamp
(Fig. 7 -25, 3) from between the muffler (4) and
exhaust pipe (2).
7. Disconnect and remove the muffler to tail pipe
connector (Fig. 7-25, 5).
8. Disconnect and remove the 2.75" U-type clamp
(Fig. 7 -25, 6) from between the tail pipe (7) and tail
pipe support bracket (8).
9. Disconnect and remove the front band clamp
(Fig. 7 -25, 9) and rear band clamp (10).
10. Disconnect and remove the tail pipe support bracket
(Fig. 7 -25, 8) from the engine.
11. Remove the tail pipe (Fig. 7 -25, 7), muffler (4) and
exhaust pipe (2).
12. Remove the battery cable clamp (not shown) when
removing the muffler bracket (Fig. 7-25, 11) from the
engine.
Figure 7- 25 Exhaust System Components
WARNING:
Exhaust fumes contain
carbon monoxide, a colorless, odorless gas
which is fatal when inhaled in a confined area.
Avoid breathing exhaust fumes, and prevent
engine operation from becoming a cause of
toxic emissions. Exhaust system components
reach high temperatures and can cause
severe burns. DO NOT come into contact with
hot exhaust system components.
WARNING:
DO NOT attempt this
procedure when the engine is hot. Wait for the
engine, muffler and tailpipes to cool down
before proceeding. Failure to do so could result
in severe burns.
