Adding Fluid - Monaco DIPLOMAT 2004 Owner's Manual

Occasionally, while the jacks are fully extended, wipe dirt from the jack
rod. This will help lengthen the life of the jacks. This can vary from the
amount and type of usage of the jacks. Dexron III will serve as a solvent as
well as a lubricant. Occasional oil or grease on the extended jack ram is
normal and aids in the lubrication of the ram. It helps to learn the sound of
the normal pumping and gurgling sounds of the pump when it is low
on fluid.

Adding Fluid:

1. Use Dexron III® automatic transmission fluid.
2. Extend any jack six inches from the full retracted position. All other
jacks should be fully retracted.
3. Unscrew the reservoir cap from the top of the pump.
4. Turn the ignition switch to the ON position. Turn the rocker switch to
ON. Open the window so the bong alarm is audible from outside the
motorhome. Slowly fill the reservoir with fluid until the bong alarm
stops sounding.
5. Replace the reservoir cap.
6. Turn the ignition switch and the remote panel OFF.
The diesel engine operates differently from the conventional gasoline
engine. Gasoline engines control engine speed using a butterfly throttle plate
controlling air/fuel mixture inlet flow. As the throttle plate opens, vacuum
created by the piston velocity draws the metered fuel/air charge into the
combustion chamber, then ignites from a controlled electric ignition source.
Closing the throttle plate limits the fuel/air supply, slowing engine speed,
increasing intake manifold vacuum.
The diesel engine in the motorhome controls engine speed by varying fuel
supply only. No throttle plates are used. An exhaust driven turbine system
(turbocharger) compresses the fresh air supply into the engine. The fuel is
injected under pressure into the combustion chamber. Ignition of fuel/air
charge occurs from heat generated by rapid high compression. The turbo
boost gauge registers amount of intake manifold pressure measured in
lbs./in². Therefore, no intake manifold vacuum exists.
Diesel engine RPM (revolutions per minute) operating speeds are
generally much lower than that of the gasoline engine. Peak torque and
horsepower output values occur at much lower engine speeds. Idle speeds
between the two engine types are similar, however maximum engine
speeds are quite different. The gasoline engine generally is not regulated
to a maximum engine speed. The maximum engine speed on a diesel
engine is controlled by an engine speed governor set by the engine
manufacturer.
