Part 2

29. REMOVE NO.3 TIMING BELT COVER
Remove the four bolts and timing belt cover.






NOTICE:
- Support the timing belt. so the meshing of the crankshaft timing pulley and timing belt does not shift.
- Be careful not to drop anything inside the timing belt cover.
- Do not allow the belt to come into contact with oil. water or dust.






30. REMOVE ENGINE HANGERS
Remove the bolt and engine hanger. Remove the two engine hangers. Remove the ground strap.
31. REMOVE ALTERNATOR BRACKET
Remove the three bolts and alternator bracket.
32. REMOVE OIL PRESSURE SWITCH






33. REMOVE CYLINDER HEAD COVER

Remove the four nuts, grommets, head cover and gasket.






HINT: Arrange the grommets in correct order, so that they can be reinstalled into their original positions. This minimizes any possibility of oil leakage due to reuse of grommets.






34. REMOVE HIGH-TENSION CORD CLAMP AND PCV VALVE FROM CYLINDER HEAD COVER
35. REMOVE CAMSHAFTS

NOTICE: Since the thrust clearance of the camshaft is small. the camshaft must be kept level while it is being removed. 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
(a) Set the knock pin of the intake camshaft at 10 - 45° BTDC of camshaft angle.

HINT: The above angle allows No.2 and No.4 cylinder cam lobes of the exhaust camshaft to push their valve lifters evenly.






(b) Secure the exhaust camshaft sub-gear to drive 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 sure that the torsional spring force of the sub-gear has been eliminated by the above operation.






(c) Remove the two bolts and rear bearing cap.






(d) Uniformly loosen and remove the six bolts on the No.1, No.2 and No.4 bearing caps in several passes in the sequence shown.

NOTICE: Do not remove the No.3 bearing cap bolts at this stage.

(e) Remove the No.1, No.2 and No.4 bearing caps.






(f) Alternately loosen and remove the two bolts on the No.3 bearing cap.

HINT:
- As the two No.3 bearing cap bolts are loosened, make sure that the camshaft is lifted out straight and level.
- If the camshaft is not being lifted out straight and level, retighten the two No.3 bearing cap bolts. Then reverse the order of above steps from (f) to (a) and reset the knock pin of the intake camshaft at 10 - 45° BTDC, and repeat steps from (b) to (f) once again.

NOTICE: Do not pry on or attempt to force the camshaft with a tool or other object.

(g) Remove the No.3 bearing cap and exhaust camshaft.






B. Remove intake camshaft
(a) Set the knock pin of the intake camshaft at 80 - 115° BTDC of camshaft angle.

HINT: The above angle allows the No.1 and No.3 cylinder cam lobes of intake camshaft to push their valve lifters evenly.






(b) Remove the two bolts, front bearing cap and oil seal.






(c) Uniformly loosen and remove the bolts on the No.1, No.3 and No.4 bearing caps in several passes in the sequence shown.

NOTICE: Do not remove the No.2 bearing cap bolts at this stage.

(d) Remove the No.1, No.3 and No.4 bearing caps.






(e) Alternately loosen and remove the two bolts on the No.2 bearing cap.

HINT:
- As the two No.2 bearing cap bolts are loosened, make sure that the camshaft is lifted out straight and level, after breaking adhesion on the front bearing cap.
- If the camshaft is not being lifted out straight and level, retighten the two No.2 bearing cap bolts. Reverse the order of above steps from (e) to (a) and reset the knock pin of the intake camshaft at 80 - 115° BTDC, and repeat steps from (b) to (e) once again.

NOTICE: Do not pry on or attempt to force the camshaft with a t6oI or other object.

(f) Remove the No.2 bearing cap and camshaft.






36. DISASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the camshaft in a vise.

NOTICE: Be careful not to damage the camshaft.






(b) Insert a service bolt (A) into the service hole of the camshaft sub-gear.
(c) Using a screwdriver, turn the sub-gear clockwise, and remove the service bolt (B).

NOTICE: Be careful not to damage the camshaft.






(d) Using snap ring pliers, remove the snap ring.






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






37. REMOVE CYLINDER HEAD
(a) passes in the sequence shown.

NOTICE: Cylinder head warpage or cracking could result from removing bolts in incorrect order.

(b) Remove the ten plate washers.






(c) The cylinder head on wooden blocks on a bench.

HINT: If the cylinder head is off, pry between the cylinder head and cylinder block with a screwdriver.

NOTICE: Be careful not to damage the contact surfaces of the cylinder head and cylinder block.
