2000 TOYOTA CAMRY Camshaft

B. Install exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10±455
BTDC of camshaft angle.
HINT: The above angle allows the No.2 and No.4
cylinder cam lobes of the exhaust camshaft to push
their valve lifters evenly.(e) Apply a light coat of engine oil on the threads and
under the heads of the bearing cap bolts.
(f) Install and uniformly tighten the 10 bearing cap bolts
in several passes, in the sequence shown.
Torque: 19 N±m (190 kgf±cm, 14 ft±lbf)
(h) Using SST, tap in the oil seal.
SST 09223±4601 1 (d) Install the bearing caps in their proper locations.
(g) Apply MP grease to a new oil seal lip.
± 5S±FE ENGINEENGINE MECHANICALEG1±70

(b) Apply MP grease to the thrust portion of the cam±
shaft.
(c) Engage the exhaust camshaft gear to the intake cam±
shaft gear by matching the timing marks on each gear.
(d) Roll down the exhaust camshaft onto the bearing
journals while engaging gears with each other.
NOTICE: There are also assembly reference marks on
each gear as shown in the Illustration. Do not use these
marks.
5. CHECK AND ADJUST VALVE CLEARANCE
(See page EG1±12)
Turn the camshaft and position the cam lobe upward,
and check and adjust the valve clearance.
Valve clearance (Cold):
Intake
0.19 ± 0.29 mm (0.007 ± 0.011 In.)
Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 In.)(e) Turn the intake camshaft clockwise or counterclockwise little
by little until the exhaust camshaft sits in
the bearing journals evenly without rocking the cam±
shaft on the bearing journals.
NOTICE: It is very important to replace the camshaft in
the bearing journals evenly while tightening bearing caps
in the subsequent steps.
(f) Install the bearing caps in their proper locations.
(g) Apply a light coat of engine oil on the threads and
under the heads of the bearing cap bolts.
(h) Install and uniformly tighten the 10 bearing cap bolts
in several passes, in the sequence shown.
Torque: 19 N±m (190 kgf±cm, 14 ft±lbf)
(i) Remove the service bolt (B).

13. TEMPORARILY INSTALL NO.1 IDLER PULLEY AND
TENSION SPRING
(a) Install the pulley with the bolt. Do not tighten the bolt
yet.
HINT: Use bolt 42 mm (1.65 in.) in length.
(b) Install the tension spring.
(c) Pry the pulley toward the left as far as it will go and
tighten the bolt.
(d) Check that the idler pulley moves smoothly.
14. INSTALL CAMSHAFT TIMING PULLEY AND
TIMING BELT
(See page EG1±33)
15. INSTALL INJECTORS AND DELIVERY PIPE
(a) California:
Install new insulator and grommet to each injector.
(b) Except California:
Install a new grommet to each injector.
(c) California:
Apply a light coat of gasoline to 2 new 0±rings, and
install them to each injector.
(d) Except California:
Apply a light coat of gasoline to a new 0±ring, and
install it to each injector.
(e) While turning the injector left and right, install it to the
delivery pipes. Install the 4 injectors.

Camshaft Position Sensor
The camshaft position sensor is mounted onto the
cylinder head. Using the protusion that is provided
on the timing pulley, the sensor generates 1 signal
for every revolution. This signal is then sent to the
ECM as a cranskshaft angle system.
