ENGINE DATA PLATE
DESCRIPTION
The engine data plate contains specific information
that is helpful to servicing and obtaining parts for
the engine. The data plate can be found affixed to the
breather cover on the left side of the engine. Informa-
tion that can be found on the data plate includes:
²Date of Engine Manufacture
²Engine Serial Number
²Control Parts List (CPL)
²Engine Rated Horsepower
²Engine Firing Order
²Engine Displacement
²Valve Lash Reset Specifications
If the engine data plate is missing or not legible,
the engine serial number is used for engine identifi-
cation. The engine serial number is stamped on the
right side of the block, on top of the oil cooler cavity
(Fig. 5).
AIR CLEANER ELEMENT
REMOVAL
Testing Air Cleaner Element using Filter MinderŸ
Do not attempt to unnecessarily remove top
of air cleaner housing for air cleaner element
inspection on diesel engines.
The air cleaner (filter) housing is equipped with an
air Filter MinderŸ gauge (Fig. 6). This air flow
restriction gauge will determine when air cleaner ele-
ment is restricted and should be replaced.
The Filter MinderŸ consists of a diaphragm and
calibrated spring sealed inside of a plastic housing
(Fig. 7). A yellow colored disc attached to diaphragm
moves along a graduated scale on side of Filter
Minder. After the engine has been shut off, a ratch-
eting device located within Filter Minder will hold
yellow disc at highest restriction that air cleaner ele-
ment has experienced. A drop in air pressure due toan air cleaner element restriction moves diaphragm
and yellow disc will indicate size of air drop.
CAUTION: Certain engine degreasers or cleaners
may discolor or damage plastic housing of Filter
Minder. Cover and tape Filter Minder if any engine
degreasers or cleaners are to be used.
To test, turn engine off. If yellow disc (Fig. 7) has
reached red colored zone on graduated scale, air
cleaner element should be replaced. Refer to Removal
/ Installation.
Resetting Filter Minder:After air cleaner (filter)
element has been replaced, press rubber button on
top of Filter Minder (Fig. 7). This will allow yellow
colored disc to reset. After button has been pressed,
yellow disc should spring back to UP position.
If Filter Minder gauge has reached red colored
zone, and after an examination of air cleaner (filter)
element, element appears to be clean, high reading
may be due to a temporary condition such as snow
build-up at air intake. Temporary high restrictions
may also occur if air cleaner (filter) element has got-
ten wet such as during a heavy rain or snow. If this
occurs, allow element to dry out during normal
engine operation. Reset rubber button on top of Filter
Minder and retest after element has dried.

Filter Removal
(1) The housing cover is equipped with spring clips
(Fig. 6) and is hinged with plastic tabs. Unlatch clips
from top of air cleaner housing and tilt housing cover
up for cover removal.
(2) Remove air cleaner element from air cleaner
housing.
INSTALLATION
(1) Before installing new air cleaner element (fil-
ter), clean inside of air cleaner housing.
(2) Position air cleaner cover to tabs on front of air
cleaner housing. Latch spring clips to seal cover to
housing.
CYLINDER HEAD
DESCRIPTION
The cylinder head is constructed of cast iron and is
a one piece cross flow design with four valves per cyl-
inder. The arrangement of two intake and two
exhaust valves per cylinder allows for a centrally
located injector. The cylinder head also includes an
integral intake manifold, an integral thermostat
housing, and a longitudal fuel return rifle, which
exits at the rear of the head. The 24 valve design
also includes integrally cast valve guides and hard-
ened intake and exhaust valve seat inserts.
REMOVAL
(1) Disconnect battery negative cables.
(2) Raise vehicle on hoist.
(3) Drain engine coolant.
(4) Disconnect exhaust pipe from turbocharger
elbow.
(5) Disconnect turbocharger oil drain tube at rub-
ber hose connection. Cap off open ports to prevent
intrusion of dirt or foreign material.

COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).
(14) Remove cooling fan support from cylinder
block.
(15) Remove upper generator bolt, loosen lower
generator bolt, and rotate generator away from cylin-
der head.
(16) Disconnect radiator upper hose from the ther-
mostat housing.
(17) Disconnect the Intake Air Temperature/Mani-
fold Air Pressure, and Coolant Temperature sensor
connectors.
(18) Remove the engine harness to cylinder head
attaching bolts and P-clips at front of head.
(19) Remove the throttle linkage cover (Fig. 8).
(20) For automatic equipped vehicles only, remove
the six (6) accelerator pedal position sensor assem-
bly-to-cylinder head bracket bolts (Fig. 9) and secure
the entire assembly out of the way. Disconnect the
APPS connector (Fig. 10).It is not necessary to
disconnect the cables from the throttle control
assembly.
(21) Remove the intake air grid heater wires from
the grid heater.
