EMI 2000
EMI 2000 is an extended maintenance interval
package. The EMI 2000 package consists of the
following key components:
•
EMI 2000-Hour Cyclonic Air Cleaner
Assembly and Air Cleaner Element
•
EMI 2000-Hour Fuel Filter (black with gold
lettering)
•
EMI 2000-Hour By-Pass Oil Filter (black with
gold lettering)
•
API Rating CI-4 Mineral Oil
•
Five Year or 12,000 Hour ELC (Extended Life
Coolant).
The EMI package allows standard maintenance
intervals to be extended to 2,000 hours, or 1 year,
whichever occurs first.
NOTE: Units equipped with the EMI 2000
package do require regular inspection in
accordance with Thermo King's maintenance
recommendations.
Engine Lubrication System
The engine has a pressure lubrication system. See
the appropriate Engine Overhaul Manual for a
detailed description of the engine lubrication
system.
Oil pressure is affected by oil temperature,
viscosity and engine speed. Subnormal oil
pressures usually may be traced to lack of oil,
faulty relief valve or worn bearings. The use of
improper viscosity oil will also produce low oil
pressure shutdowns.
Engine Oil Pressure Switch/Sensor
Engine oil pressure should rise immediately on
starting. If engine oil pressure drops below 10 ± 2
psig (69 ± 14 kPa), the switch/sensor signals the
microprocessor to stop the engine. See the
appropriate Microprocessor Diagnostic Manual
for diagnostic information.
Engine Oil Change
The engine oil should be changed according to the
“Maintenance Inspection Schedule”. Drain the oil
only when the engine is hot to ensure that all the
oil drains out. When changing oil, try to make
sure that the truck is not tipped away from the
direction that the oil is supposed to flow from the
oil pan. It is important to get as much of the
residual oil out as possible because most of the
dirt particles are in the last few quarts of oil to
drain out. Refill the pan with oil (see the
“Specifications” chapter) and check the dipstick
level. Run the unit, and then recheck the oil level.
NOTE: Fill the crankcase slowly so oil will not
run through the crankcase breather into intake
manifold and fill up an open cylinder. Leaving
the dipstick out while adding engine oil will vent
the crankcase.
Add oil as necessary to reach the full mark. See
the “Specifications” chapter of this manual for
correct type of oil.
