Removing the Exhaust System (continued)
2. Block the wheels with chocks to prevent the machine from moving.
3. Unlatch the hood and raise it. Allow engine and exhaust system to cool
before doing any disassembly of exhaust system components.
4. Remove the exhaust system components as shown in Figure 31 and Figure
32 . Discard all gaskets that were removed (items 1 and 15 in Figure 31 ).
Note: The exhaust system DPF and DOC can be removed from the exhaust
system without removing the entire exhaust system from the engine. Refer to
the Yanmar Engine Service Manual for complete disassembly and assembly
procedures.
Installing the Exhaust System
Note: Ensure that all exhaust system flanges and sealing surfaces are free of
debris or damage that may prevent a tight seal.
1. Ensure to install new gaskets in place of all gaskets that were removed. Do
not use any type of gasket sealant on gasket or flange surfaces.
2. Assemble all exhaust system components that were removed ( Figure 31
and Figure 32 ).
A. If exhaust sensors (items 7 and 8 in Figure 31 ) were removed, torque the
sensors to 25 to 40 N∙m (19 to 29 ft-lb) .
B. If exhaust pressure pipes (items 26 and 28 in Figure 31 ) were removed,
replace the sensor gaskets on both sides of the pressure pipe fitting.
C. Adjust the muffler guard on frame so there is 9.5 mm (3/8 inch) clearance
between the exhaust tube and the guard in all directions. Ensure that
the rear cutting units and lift arms do not contact exhaust tube when
the cutting units are fully raised.
3. Lower the hood and secure it with the latches.
