200 ENGINE INSTALLATION & TESTING
5. Prime the SECONDARY fuel filter element
(green) by filling with clean No. 2 fuel oil. Do
not fill filter through center hole; it must be
filled using outer holes. Lubricate gasket
with oil and install filter.
FINAL PREPARATION
Lubrication
A lubricating oil film coats rotating parts and
bearings of an overhauled engine, but this may
not provide sufficient lubrication when engine is
started for the first time. The following briefly
describes the recommended procedure for
ensuring proper lubrication.
Do not mix brands or types of lubricants.
Chemical additives may be incompatible and may
contribute to the formation of sludge, acid or
hardening.
Usually there are various points on the engine
where a pressure line may be tapped into, but if
no other is apparent, the oil gauge line may be
disconnected and pressure tank applied at that
point.
ENGINE LUBRICATION SYSTEM (PRIMING)
1. Fill engine crankcase with EO-L engine oil.
MACK-specified EO-L engine lubricant is
recommended. E7 series engine capacity is
33.5 quarts (32 liters).
2. Fill a pressure prelubricator (J 39258-A) with
the recommended oil and connect pressure
prelubricator to main oil gallery. Prime
engine lubrication system with sufficient oil.
3. Remove oil level dipstick and check
crankcase level. Add sufficient oil, if
necessary, to bring it to the FULL mark on
dipstick. Do not overfill.
TURBOCHARGER
1. Disconnect turbocharger oil inlet line and
pour approximately one pint (473 ml) of
clean engine oil into line. This ensures that
bearings are properly lubricated for initial
start-up.
2. Reconnect oil line.
AIR INLET SYSTEM
1. Check the integrity of air inlet system.
2. Inspect all piping, connections and the air
cleaner element. Replace components as
required.
COOLING SYSTEM
1. Check cooling system. Make sure all plugs
are installed and tight. Make sure thermostat
is installed.
2. Fill system with recommended coolant.
To ensure that all air is purged from cooling
system, remove a plug from top (or end) of
coolant manifold during filling. This will eliminate
any air that was trapped as a result of rapid filling.
3. Install a new coolant conditioner and fill with
the recommended coolant mixture.
4. Check that all plugs and thermostat(s) are
installed.
FUEL INJECTION PUMP (MECHANICALLY
GOVERNED AND V-MAC ENGINES)
1. Remove the TEM sensor or the 12-mm plug
in the governor housing.
2. Fill pump housing with 12 ounces (355 ml) of
EO-L engine lubricant.
3. Reinstall TEM sensor or 12-mm plug.
Prelubing should be performed after new and
used injection pumps are installed on the engine.
