ENGINE
Description
The engine (1, Figure 7-1) is a Cummins B 6.7L diesel
engine. The engine (1) is equipped with a torque converter
(2). A drive shaft (4) connects the torque converter (2) and
transmission (3). The engine and torque converter are
considered one assembly. Four combinations of the engine
and torque converters are available:
• Stage V/Tier 4 Final Cummins B 6.7L with torque
converter with lockup.
• Stage V/Tier 4 Final Cummins B 6.7L with torque
converter without lockup.
• Non-certified Cummins B 6.7L with torque converter with
lockup.
• Non-certified Cummins B 6.7L with torque converter
without lockup.
For more details about the engine, torque converter, and
transmission, see List Of Specifications, page 1-3.
This Service Manual does not include detailed information
on the engine itself. A separate manual as prepared in detail
by the engine manufacturer, is supplied with this Service
Manual. However, a short description and maintenance of
certain components of the fuel system, air intake system,
and water cooling system is provided in this section.
The engine is electronically controlled by the Electronic
Control Module (ECM); it is the control center of the system.
It processes all of the inputs and sends commands to the fuel
systems as well as vehicle and engine control devices. On
Stage V/Tier 4 Final engines, the ECM also controls the
Diesel Exhaust Fluid (DEF) system.
The foot throttle pedal in the cab controls the engine speed.
It controls engine RPM which increases or decreases
proportionately with the amount of foot pressure applied to
the pedal. Engine speed is also controlled by the idle switch,
which is a three position rocker switch located on the upper
right control panel. The idle switch allows the operator to
infinitely vary and hold the engine speed between the
engine’s minimum and maximum idle settings (refer to
Section 3, Operating Controls and Procedures in the
Operator Manual for details on the operation of the idle
switch). The foot throttle pedal is electrically connected to the
superstructure control module which sends the signal to the
engine ECM via the J1939 data link.
The engine and its components are enclosed in a hood
assembly with a grill in the rear of the hood for adequate air
circulation. Access to the engine is gained through a door
assembly in the top of the hood that opens from both sides.
