ENGINE LUBRICATION SYSTEM
ENGINE LUBRICATION
Refer to Group 0, Lubrication and Maintenance for
recommended oil to be used in various engine appli-
cation. System is full flow filtration, pressure feed
type. The oil pump is mounted in the front engine
cover and driven by the crankshaft. Pressurized oil is
then routed through the main oil gallery, running the
length of the cylinder block, supplying main and rodbearings with further routing. Rod bearing oil throw-
off lubricates the pistons from directed slots on the
side of the connecting rod assemblies. Camshaft and
valve mechanisms are lubricated from a full-length
cylinder head oil gallery supplied from the crankcase
main oil gallery.
PRESSURE LUBRICATION
Oil drawn up through the pickup tube is pressur-
ized by the pump and routed through the full flow fil-
ter to the main oil gallery running the length of the
cylinder block. A cylinder head restrictor, located in
the block, provides increased oil flow to the main oil
gallery (Fig. 2).
MAIN/ROD BEARINGS
A diagonal hole in each bulkhead feeds oil to each
main bearing. Drilled passages within the crankshaft
route oil from main bearing journals to connecting
rod journals.
CAMSHAFT/HYDRAULIC LASH ADJUSTERS
A vertical hole at the number five bulkhead routes
pressurized oil through a restrictor up into the cylin-
der head. The rocker shafts route oil to the rocker
arms/hydraulic lash adjuster assemblies.

SERVICE PROCEDURES
CYLINDER BORE AND PISTON SIZING
The cylinder walls should be checked for out-of-
round and taper with Tool C-119 (Fig. 3). The cylin-
der bore out-of-round is 0.050 mm (.002 inch)
maximum and cylinder bore taper is 0.051 mm (0.002
inch) maximum. If the cylinder walls are badly
scuffed or scored, the cylinder block should be
rebored and honed, and new pistons and rings fitted.
Whatever type of boring equipment is used, boring
and honing operation should be closely coordinated
with the fitting of pistons and rings in order that
specified clearances may be maintained.Refer to
Honing Cylinder Bores outlined in the Stan-
dard Service Procedures for specification and
procedures.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 3). Top measurement should be
10 mm (3/8 inch) down and bottom measurement
should be 10 mm (3/8 inch.) up from bottom of bore.
Refer to Cylinder Bore and Piston Specifications
Chart.
SIZING PISTONS
Piston and cylinder wall must be clean and dry.
Piston diameter should be measured 90 degrees to
piston pin about 17.5 mm (11/16 inch) from the bot-tom of the skirt as shown in (Fig. 4). Cylinder bores
should be measured halfway down the cylinder bore
and transverse to the engine crankshaft center line
shown in (Fig. 3). Refer to Cylinder Bore and Speci-
fications Table. Correct piston to bore clearance must
be established in order to assure quiet and economi-
cal operation.
Chrysler engines use pistons designed specifically
for each engine model. Clearance and sizing locations
vary with respect to engine model.
NOTE: Pistons and cylinder bores should be mea-
sured at normal room temperature, 21ÉC (70ÉF).
FITTING PISTON RINGS
(1) Wipe cylinder bore clean. Insert ring and push
down with piston to ensure it is square in bore. The
ring gap measurement must be made with the ring
positioning at least 12 mm (0.50 inch) from bottom of
cylinder bore. Check gap with feeler gauge (Fig. 5).
Refer to Piston Ring Specification Chart.

DESCRIPTION AND OPERATION
LUBRICATION SYSTEM
The pressurized system (Fig. 2) uses a rotary pump
(3) located in the front of the engine block, driven by
a gear which meshes directly with the crankshaft
gear. All the oil sent to every lubricated part is fil-
tered. The pump sends the oil through a pressure
relief valve (2) to the filter (7) and through galleries
in the crankcase to the crankshaft bearings (8), cam-
shaft bearings (11) and turbocharger (10). The piston
pins, connecting rod small ends and insides of the
pistons are lubricated and cooled by oil sprayed out
from jets (9) in the crankshaft mounting blocks. The
lubricating oil is sent to the rockers (12) through anexternal pipe (Fig. 3). A valve in the filter cartridge
enables the oil to be circulated even when the car-
tridge is clogged.

HOSES AND CLAMPS
Inspect all hose connections (clamps and quick con-
nect fittings) for completeness and leaks. Replace
cracked, scuffed, or swelled hoses. Replace hoses that
rub against other vehicle components or show sign of
wear.
Fuel injected vehicles use specially constructed
hoses. When replacing hoses, only use hoses marked
EFM/EFI.
When installing hoses, ensure that they are routed
away from contact with other vehicle components
that could rub against them and cause failure. Avoid
contact with clamps or other components that cause
abrasions or scuffing. Ensure that rubber hoses are
properly routed and avoid heat sources.
The hose clamps have rolled edges to prevent the
clamp from cutting into the hose. Only use clamps
that are original equipment or equivalent. Other
types of clamps may cut into the hoses and cause
high pressure fuel leaks. Tighten hose clamps to 1
N´m (10 in. lbs.) torque.

GENERAL INFORMATION
STEERING SYSTEM AND COMPONENT
DESCRIPTION
The power steering system consists of these four
major components. Power Steering Pump, Power
Steering Gear, Pressure Hose, and Return Line.
Turning of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth. Power assist steering is
provided by an open center, rotary type control valve.
It is used to direct oil from the pump to either side of
the integral steering rack piston.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As requiredsteering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston,
which, in turn, builds up hydraulic pressure and
assists in the turning effort.
Drive tangs on the power steering gear pinion
shaft, mate loosely with the shaft of the steering
gear. This is to allow manual steering control to be
maintained, if the drive belt on the power steering
pump should break. However, under these conditions,
steering effort will significantly increase.
