Page: 96 / 662

General Information
This chapter gives information about specifications, troubleshooting, testing and
repair of the Kubota gasoline engine used in Reelmaster 5410-G and 5510-G
machines.
Most repairs and adjustments require tools which are commonly available in
many service shops. The use of some specialized test equipment is explained in
the engine service manual included at the end of this chapter. However, the cost
of the test equipment and the specialized nature of some repairs may dictate that
the work be done at an engine repair facility.
Service and repair parts for Kubota gasoline engines are supplied through your
local Toro Distributor. If a parts list is not available, be sure to provide your
distributor with the Toro model and serial number.
Traction Unit Operator’s Manual
The Traction Unit Operator’s Manual provides information regarding the
operation, general maintenance and maintenance intervals for the Kubota
gasoline engine that powers your Reelmaster machine. The
Kubota Operator’s
Manual includes information specific to the engine used in your Reelmaster.
Refer to these publications for additional information when servicing the machine.
Kubota Workshop and Diagnosis Manuals
The engine that powers your Reelmaster machine is a Kubota model
WG1605-G-E3. Both the Kubota Workshop Manual and Kubota Diagnosis
Manual are available for this engine. Ensure that the correct engine manuals are
used when servicing the engine on your Reelmaster.
Kubota Gasoline Engine
The engine used on your Reelmaster is a Kubota WG Series gasoline engine.
Engine features include an electronic control unit (ECU) that controls a common
rail fuel injection system with direct injection, electronic throttle body (ETB),
an electronic governor and a catalytic muffler exhaust system with 2 oxygen
sensors. Numerous engine sensors are used to allow the engine ECU to monitor
and control engine operation for optimum engine performance.
The engine electrical components (e.g., ECU, O2 sensor, throttle control, power
relay, and ETV relay) are identified and matched in the engine ECU program. If
engine electrical components are replaced on the engine, the Kubota electronic
tool must be used by your Toro distributor to update the ECU program which
will ensure correct engine operation.
During machine operation, if an engine fault occurs, the machine InfoCenter
display can be used to identify the fault. Also, the Kubota gasoline engine
service tool can be used by your Toro distributor to confirm the real-time engine
running status and to offer timely technical services.
Engine Electronic Control Unit (ECU)
The Kubota gasoline engine that powers your Reelmaster uses an electronic
control unit (ECU) for engine management. The engine ECU also communicates
with the machine Toro Electronic Controller (TEC) and the operator InfoCenter
display on the machine through the machine CAN-bus system. All wire harness
electrical connectors should be plugged into the engine ECU before the machine
key switch is moved from the O
FF
position to either the O
N
/R
UN
or S
TART
position.
