service TOYOTA CAMRY V20 1986 Service Information

.
(d) Insert a service bolt (A) into the service hole of the camshaft
sub±gear.
(e) Using a screwdriver, align the holes of the camshaft main
gear and sub±gear by turning camshaft sub±gear clock-
wise, and install a service bolt (B).
NOTICE: Be careful not damage the camshaft.
4. INSTALL CAMSHAFTS
HINT: Since the thrust clearance of the camshaft is small,
the camshaft must be held level while it is being installed.
If the camshaft is not kept level, the portion of the cylinder
head receiving the shaft thrust may crack or be damaged,
causing the camshaft to seize or break. To avoid this, the
following steps should be carried out.
A. Install intake camshaft
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Place the intake camshaft at 80° BTDC of camshaft angle
on the cylinder head. 2. INSTALL SPARK PLUG TUBES
(a) Clean the cylinder head tube holes of any residual adhesive, oil
foreign particles. Remove any oil with kerosene or gasoline.
(b) Screw the threads of the spark plug tube coated with adhesive
into the cylinder head.
(c) Install the spark plug tube nut and using a 30 mm socket
wrench, torque the nuts.
Torque: 400 kg±cm (29 ft±lb, 39 N±m)
3. ASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagonal wrench head portion of the camshaft
in a vice.
(b) Install the following parts:
(1) Camshaft gear spring
(2) Camshaft sub±gear
(3) Wave washer
(c) Using snap ring pliers, install the snap ring.

(b) Apply MP grease to the thrust portion of the camshaft.
(c) Engage the exhaust camshaft gear gear to the intake
camshaft gear by matching the timing marks on each
gear.
(d) Roll down the exhaust camshaft onto the bearing jour-
nals 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.
(e) Turn the intake camshaft clockwise or counterclock-
wise little by little until the exhaust camshaft sits in the
bearing journals evenly without rocking the camshaft
on the bearing journals.
NOTICE: This 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 location.
(g) Apply alight coat of engine oil on the threads and under
the heads of bearing cap bolts.
(h) Install and uniformly tighten the ten bearing cap bolts
in several passes in the sequence shown.
Torque: 190 kg±cm (14 ft±lb, 19 N±m)
(i) Remove the service bolt (8).
5. INSTALL CYLINDER HEAD COVER
(a) Apply seal packing to the cylinder head as shown in the fig-
ure.
Seal packing: Part No.08826±00080 or equivalent B. Install exhaust camshaft
(a) Set the knock pin of the intake camshaft at 100 BTDC of
camshaft angle.

(b) Secure the exhaust camshaft sub±gear to the driven
gear with a service bolt.
Recommended service bolt:
Thread diameter 6 mm
Thread pitch 1.0 mm
Bolt length 16 ± 20 mm (0.63 ± 0.79 in.)
HINT: When removing the camshaft, make certain that
the torsional spring force of the sub±gear has been
eliminated by the above operation. 32. REMOVE CYLINDER HEAD COVERS
Remove the six nuts, seal washers, cylinder head cover and
gasket. Remove the two cylinder head covers.
33. REMOVE SPARK PLUG TUBE GASKETS
Remove the six tube gaskets.
34. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the. camshaft is
small, the camshaft must be held level while it is being re-
moved. If the camshaft is not kept level, the portion of the
cylinder head receiving the shaft thrust may crack or be
damaged, causing the camshaft to seize or break. To avoid
this, the following steps should be carried out.
A. Remove exhaust camshaft of RH cylinder head
(a) Align the timing marks (two pointed marks) of the camshaft
drive and driven gears by turning the camshaft with a
wrench.
(c) Uniformly loosen and remove the eight bearing cap
bolts in several passes in the sequence shown.
(d) Remove the four bearing caps and exhaust camshaft.

(b) Secure the exhaust camshaft sub±gear to the driven
gear with a service bolt.
Recommended service bolt:
Thread diameter 6 mm
Thread pitch 1.0 mm
Bolt length 16 ± 20 mm (0.63 ± 0.79 in.)
HINT: When removing the camshaft, make certain that
the torsional spring force of the sub±gear has been
eliminated by the above operation.
D. Remove intake camshaft of LH cylinder head
(a) Uniformly loosen and remove the ten bearing cap
bolts in several passes in the sequence shown.
(b) Remove the five bearing caps, oil seal and intake camshaft.B. Remove intake camshaft of RH cylinder head
(a) Uniformly loosen and remove the ten bearing cap
bolts in several passes in the sequence shown.
(b) Remove the five bearing caps, oil seal and intake camshaft.
C. Remove exhaust camshaft of LH cylinder head
(a) Align the timing marks (one pointed mark) of the camshaft
drive and driven gears by turning the camshaft with a
wrench.
(c) Uniformly loosen and remove the eight bearing cap
bolts in several passes in the sequence shown.
(d) Remove the four bearing caps and exhaust camshaft.

(e) Remove the following parts:
(1) Wave washer
(2) Camshaft sub±gear
(3) Camshaft gear spring

springs (RH and LH). (b) Insert service bolt (A) into the service hole of the cam-
shaft sub±gear.
(c) Using a screwdriver, turn the sub±gear clockwise, and
