Engine Maintenance
99
Thermo King recommends that any major
injection pump or nozzle repairs be done by a
quality diesel injection service specialty shop. The
investment in equipment and facilities to service
these components is quite high. Therefore, this
equipment is not found in most repair shops.
The following procedures can be done under field
conditions:
•
Bleeding air from the fuel system.
•
Maintenance involving the fuel tank and filter
system.
•
Speed and governor adjustments.
•
Electric transfer pump replacement or repair
(10 psig [69 kPa] pump with diesel filter).
•
Injection line replacement.
•
Pump timing.
•
Nozzle spray pattern testing and adjustment.
•
Minor rebuilding of nozzles.
Bleeding the Fuel System
The fuel system will have to have the air bled out
if the engine runs out of fuel, if repairs are made
to the fuel system, or air gets into the system for
any other reason.
NOTE: MAKE SURE to keep the fuel tank vent
open. If the vent becomes clogged, a partial
vacuum develops in the tank, and this increases
the tendency for air to enter the system.
Proceed as follows:
1. Loosen the bleeder screw on the inlet fuel
fitting of the injection pump.
2. Turn on the electric fuel pump. The electric
fuel pump is energized when the
O
N
key is
pushed. Tighten the bleeder screw on the
injection pump when clear flow of fuel
appears.
NOTE: At initial start-up, open the bleeder
screw at the injection pump and bleed fuel
until a clear flow is noted.
3. Loosen the injector lines on the injection
nozzles.
4. Crank the engine until fuel appears at the
nozzles. Tighten the injector lines, and start
the engine.
NOTE: Fuel will not appear at the nozzles by
merely running the electric pump. The
engine must be cranked.
