Reelmaster 7000−DPage 3 − 12Yanmar Diesel Engine
Reelmaster 7000−D models that are powered by a dies-
el engine that complies with EPA Tier 4 emission regula-
tions are equipped with an exhaust system that includes
a diesel oxidation catalyst (DOC) and a diesel particu-
late filter (DPF). These exhaust components require
service or component replacement at intervals identified
in your Operator’s Manual. Additionally, the exhaust as-
sembly uses two (2) temperature sensors and a pres-
sure differential sensor which are used as inputs for the
engine ECU to monitor the operation of the exhaust sys-
tem.
The diesel particulate filter (DPF) is cleaned periodically
through a regenerative process that is controlled by the
engine ECU (see the General Information section of this
chapter). The InfoCenter display will identify the status
of DPF regeneration. At recommended intervals, DPF
reconditioning is necessary which will require exhaust
system disassembly, DPF removal and DPF recondi-
tioning by a company that has the necessary equip-
ment. Once the DPF has gone through the
reconditioning process, it can be re−installed in the ex-
haust system. Contact your Toro Distributor for informa-
tion on reconditioning the DPF.
The diesel oxidation catalyst (DOC) has a service life ex-
pectancy and requires replacement at recommended
intervals. Replacement of the DOC will require exhaust
system disassembly, removal of the existing DOC and
installation of the new DOC.
Additional information about the diesel particulate filter
(DPF) operation and maintenance can be found in the
Yanmar Service Manual and the Yanmar Troubleshoot-
ing Manual.
Removal (Figs. 6 and 7)
NOTE: The exhaust system DPF and DOC can be re-
moved from the exhaust system without removing the
entire exhaust from the engine. Certain engine service
procedures (e.g. rocker cover removal for valve clear-
ance adjustment) will require removal of the exhaust
system assembly.
CAUTION
The muffler and exhaust pipe may be hot. To
avoid possible burns, allow the engine and ex-
haust system to cool before working on the ex-
haust system.
1. Raise and support hood to gain access to exhaust
system. Allow engine and exhaust to cool before doing
any disassembly of exhaust system components.
2. Remove exhaust system components from the en-
gine as necessary. Discard all gaskets removed.
Installation (Figs. 6 and 7)
NOTE: Make sure that all exhaust system flanges and
sealing surfaces are free of debris or damage that may
prevent a tight seal.
1. Make sure to install new gaskets in place of all gas-
kets that were removed. Do not use any type of gasket
sealant on gasket or flange surfaces.
2. Assemble all removed exhaust system components.
A. If exhaust temperature sensors (Fig. 6 items 7
and 8) were removed, tighten sensors from 19 to 29
ft−lb (25 to 40 N−m).
B. If exhaust pressure pipes ( Fig. 6 items 26 and 28)
were removed, replace sensor gaskets (item 27) on
both sides of the pressure pipe fitting. Tighten pipe
fittings from 33 to 40 ft−lb (45 to 55 N−m).
C. If DPF stiffeners (Fig. 6 items 18, 19, 20 and 21)
were loosened or removed, tighten fasteners that se-
cure stiffeners before tightening fasteners that se-
cure exhaust system to DPF stays.
