REMOVAL
(1) Remove the timing belt (Refer to 9 - ENGINE/
VALVE TIMING/TIMING BELT AND SPROCKETS -
REMOVAL).
(2) Remove timing belt idler pulley (Fig. 124).
(3) Hold camshaft sprocket with Special Tool 6847
while removing bolt (Fig. 125). Remove both cam
sprockets.
(4) Remove rear timing belt cover fasteners and
remove cover from engine (Fig. 126).
(5) Remove lower bolt attaching timing belt ten-
sioner assembly to engine and remove tensioner as
an assembly (Fig. 127).
INSTALLATION
(1) Align timing belt tensioner assembly to engine
and install lower mounting bolt but do not tighten
(Fig. 127). To properly align tensioner assembly—in-
stall one of the engine bracket mounting bolts (M10)
5 to 7 turns into the tensioner’s upper mounting loca-
tion (Fig. 127).
(2) Torque the tensioner’s lower mounting bolt to
61 N·m (45 ft. lbs.). Remove the upper bolt used for
tensioner alignment.
(3) Install rear timing belt cover and fasteners.
Torque fasteners to values specified in (Fig. 126).

BALANCE SHAFTS AND
CARRIER ASSEMBLY
DESCRIPTION
The 2.4L engine is equipped with two nodular cast
iron balance shafts installed in a cast aluminum car-
rier attached to the lower cylinder block (Fig. 128).
OPERATION
The balance shafts are driven by the crankshaft
via a roller chain and sprockets. The balance shafts
are connected by helical gears. The dual counter
rotating shafts decrease second order vertical shak-
ing forces caused by component movement.
REMOVAL
BALANCE SHAFTS/CHAIN/SPROCKETS
NOTE: For service procedures requiring only tem-
porary relocation of carrier assembly refer to BAL-
ANCE SHAFT CARRIER procedure below.
(1) Drain engine oil.
(2) Remove the oil pan and pick-up tube (Refer to
9 - ENGINE/LUBRICATION/OIL PAN - REMOVAL).
(3) If replacing crankshaft sprocket, remove oil
pump (Refer to 9 - ENGINE/LUBRICATION/OIL
PUMP - REMOVAL).
(4) Remove chain cover, guide and tensioner. Dis-
card pivot screw and adjuster screw. (Fig. 129).
(5) Remove screw retaining balance shaft drive
sprocket (Fig. 130). Remove chain and sprocket.
(6) Using two wide pry bars, work the crankshaft
sprocket back and forth until it is off the crankshaft-
shaft.
(7) Remove gear cover retaining stud (double
ended to also retain chain guide). Remove cover and
balance shaft gears (Fig. 131).
(8) Remove rear cover and balance shafts (Fig.
132).
(9) Remove four carrier to crankcase attaching
bolts to separate carrier from engine bedplate.
BALANCE SHAFT CARRIER
The following components will remain intact dur-
ing carrier removal: Gear cover, gears, balance shafts
and the rear cover (Fig. 128).
(1) Drain engine oil.
(2) Remove the oil pan and pick-up tube (Refer to
9 - ENGINE/LUBRICATION/OIL PAN - REMOVAL).
(3) Remove chain cover, guide and tensioner (Fig.
129).
