DIAGNOSIS AND TESTING (Continued)

BALANCE SHAFTS
Balance shaft lubrication is provided through an
oil passage from the number 1 main bearing cap
through the balance shaft carrier support leg. This
passage directly supplies oil to the front bearings and
internal machined passages in the shafts that routes
oil from front to rear shaft bearing journals
SPLASH LUBRICATION
Oil returning to the pan from pressurized compo-
nents supplies lubrication to the valve stems. Cylin-
der bores and wrist pins are splash lubricated from
directed slots on the connecting rod thrust collars.
ENGINE COMPONENTS
BALANCE SHAFTS:2.4L engines are equipped
with two balance shafts installed in a carrier
attached to the lower crankcase. The shafts intercon-
nect through gears to rotate in opposite directions.These gears are driven by a short chain from the
crankshaft, to rotate at two times crankshaft speed.
This counterbalances certain engine reciprocating
masses.
CYLINDER BLOCK AND BEDPLATE ASSEM-
B LY:A closed deck design is used for cooling and
weight reduction with water pump molded into the
block. Nominal wall thickness is 4.5 mm. The bed-
plate incorporates main bearing caps. Rear seal
retainer is integral with the block.
CRANKSHAFT:A nodular cast iron crankshaft is
used. The engine has 5 main bearings, with number
3 flanged to control thrust. The 60 mm diameter
main and 50 mm diameter crank pin journals (all)
have undercut fillets that are deep rolled for added
strength. To evenly distribute bearing loads and min-
imize internal stress, 8 counterweights are used.
Hydrodynamic seals provide end sealing, where the
crankshaft exits the block. Anaerobic gasket material
is used for parting line sealing in the block. A sin-
tered powder metal timing belt sprocket is mounted
on the crankshaft nose. This sprocket provides
motive power; via timing belt to the camshaft sprock-
ets (providing timed valve actuation) and to the
water pump.
PISTONS:There is provisions for free wheeling
valve train. Piston has a unique height. All engines
use pressed in piston pins to attach forged powder
metal connecting rods. Incorporate hex head cap
screw threaded into the connecting rod. Piston and
Rods are serviced as a assembly.
PISTONS RINGS:The piston rings include a
molybdenum faced top ring for reliable compression
