POWER TRAIN TMS800E SERVICE MANUAL
The superstructure cab foot throttle pedal and the increment/
decrement switch are active while in craning mode (the
superstructure key switch is in the ignition “RUN” position).
While in craning mode, the percent throttle will reflect which
ever superstructure cab device is requesting the most RPM
and the carrier cab foot pedal position is ignored.
The engine and its components are enclosed within a hood
assembly. The hood has openings in the front and rear to
allow for adequate air flow over the engine. A door on the top
left and right side of the hood may be opened to provide
easier access to the engine.
The air intake filter is located on the right side of the engine
on the fender. The exhaust system is located on the left side
behind the cab. It is mounted to the decking and boom rest
support.
To aid in starting the engine in cold weather, an automatic
cold weather starting aid injection system is provided. When
engine senses that the temperature is below 4°C (40°F), the
automatic cold start solenoid is activated when the engine is
started providing an injection of starting fluid to the engine.
The system consists of an engine temperature switch,
solenoid valve, starting aid container, and the necessary
connecting tubing. The solenoid and container are mounted
inside the hood on the left side. An immersion type engine
block heater is also provided.
MAINTENANCE
Removal
1. Fully extend and set the outriggers and position the
boom over the side to provide working clearance.
2. Disconnect the battery (Refer to Electric System, page
3-1).
3. Open the left and right hood access doors.
4. Disconnect and remove the air filter tubing from the
engine and air cleaner.
5. Drain the engine lubricating systems.
6. Drain the transmission systems.
7. Drain the engine coolant system.
8. Tag the starting aid (ether) tubing. Disconnect the tubing
from the injector nozzle on the engine intake manifold.
Cap or plug the openings of the tubing and the injector.
As needed, remove ether cylinder to prevent ether
discharge.
9. Disconnect the exhaust tubing at the engine and
aftertreatment assembly (DPF). Remove the tubing
clamp and exhaust bracket from the rear of the engine
and remove the tubing from the engine.
10. Unplug aftertreatment assembly wiring harness from
carrier harness and aftertreatment assembly. Unstrap
this harness from boom rest tie bars.
11. Remove support brace between aftertreatment stack
and boom rest weldment.
12. Remove the engine hood assembly, counterweight
stowage frame work and decking over transmission.
13. Tag and disconnect hoses from the No. 1 pump and cap
or plug all openings.
14. Unbolt the pump propeller shaft from the engine and
pump coupler. Disconnect clutch air line and electrical
harness (ISX engine only). Remove the No. 1 pump.
Pump and clutch weighs approximately 213 kg (470 lb)
(ISX engine). QSX pump installation weighs
approximately 168 kg (370 lb).
15. Attach adequate lifting device to the engine and
transmission sufficient to lift and support both the engine
and transmission.
NOTE: Boom rest weighs approximately 68 kg (150 lb).
Ensure lifting device is sufficient to lift the boom
rest.
16. Attach an adequate lifting device and remove the boom
rest.
17. Tag and disconnect the engine electrical connections
from the starter and the alternator, the starting aid valve
connector, and the battery cables.
18. Tag and disconnect the transmission oil lines to the
transmission filter and the transmission oil cooler.
19. Disconnect and remove the drive line from the
transmission. Refer to DRIVE TRAIN in this section.
