ENGINE FINAL PREPARATION
AND OPERATIONAL CHECK
Filter Element Installation
All filters and coolant conditioners must meet
MACK specifications. Prime oil filters before
installation using the correct specification engine
oil.
1. Install a new air filter in the air filter housing.
2. Install the applicable Centri-Max
®
(externally
drained) or Centri-Max
®
PLUS (internally
drained) filter assembly. Be sure to use a
new rotor element and O-ring.
There are different rotor assemblies for the
standard Centri-Max
®
(externally drained) and
Centri-Max
®
PLUS (internally drained) filter
assemblies. Take care to use the correct rotor for
the applicable configuration. While either of the
two rotors available for the externally drained
configuration will slide on the spindle of the
internally drained configuration, they will be loose
and not rotate, causing the unit to not function.
3. Using an appropriate filter wrench such as
J 29927, install the two full-flow oil filter
elements and coolant conditioner element.
Prime the fuel filter elements before installation.
Use only clean, MACK-specified, Grade 2D
diesel fuel.
4. Prime the PRIMARY fuel filter element (red)
by filling with clean No. 2 fuel oil. Do not fill
the filter through the center hole; it must be
filled using the outer holes. Lubricate the
gasket with oil and install the filter.
5. Prime the SECONDARY fuel filter element
(green) by filling with clean No. 2 fuel oil. Do
not fill the filter through the center hole; it
must be filled using the outer holes.
Lubricate the gasket with oil and install the
filter.
Engine Lubrication System
GENERAL INSTRUCTIONS
A lubricating oil film coats rotating parts and
bearings of an overhauled engine, but this may
not provide sufficient lubrication when the 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 a pressure tank applied at that
point.
PRIMING THE LUBRICATION SYSTEM
1. Fill the engine crankcase to the specified
capacity with the recommended MACK-
specified EO-M engine oil.
2. Fill a pressure prelubricator (J 39258-A) with
the recommended oil and connect the
pressure prelubricator to main oil gallery.
Prime the engine lubrication system with
sufficient oil.
3. Remove the oil level dipstick and check the
crankcase level. Add sufficient oil, if
necessary, to bring it to the FULL mark on
the dipstick. Do not overfill.
Turbocharger
1. Disconnect the turbocharger oil inlet line and
pour approximately one pint (473 ml) of
clean engine oil into the line. This ensures
that the bearings are properly lubricated for
initial start-up.
2. Reconnect the oil line.
