20. IF NECESSARY, REMOVE SEMI-CIRCULAR PLUGS AND CAMSHAFT HOUSING PLUGS
21. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed.
Otherwise, excessive pressure is put on the cylinder head journal thrust, causing a burr on the journal and damage on the camshaft. To avoid this, follow the steps below.
(a) Check the crankshaft pulley position.
Check that the timing mark of the crankshaft pulley is aligned with the centers of the crankshaft pulley bolt and the idler pulley bolt.
NOTICE: Having the crankshaft pulley at the wrong angle can cause the piston head and the valve head to come into contact with each other when removing the camshaft, causing damage on them. So always set the crankshaft pulley at the correct angle.
(b) Remove the RH camshafts.
- Move a service bolt of the sub-gear upward by turning the hexagon shaped port of the exhaust camshaft with a wrench.
- Secure the sub-gear to the main gear with a service bolt.
Recommended service bolt:
HINT: When removing the camshafts, make sure that the torsional spring force of the sub-gear is eliminated by the above operation.
- Set the timing mark (1 dot mark) of the camshaft main gear at approx. 10 angle by turning the hexagon wrench head portion of the exhaust camshaft with a wrench.
- Uniformly loosen and remove the 22 bearing cap bolts a little at a time for several times in the sequence shown.
- Remove the oil feed pipe, 9 bearing caps, cam shaft timing oil control valve and camshafts.
(c) Remove the LH camshafts.
- Move a service bolt of the sub-gear upward by turning the hexagon shaped port of the exhaust camshaft with a wrench.
- Secure the sub-gear to the main gear with a service bolt.
Recommended service bolt:
HINT: When removing the camshaft, make sure that the torsional spring force of the sub-gear is eliminated by the above operation.
- Align the timing mark (2 dot marks) of the camshaft drive gear by turning the hexagon wrench head portion of the exhaust camshaft with a wrench.
- Evenly loosen and remove the 22 bearing cap bolts a little at a time for several times as in the sequence shown.
- Remove the oil feed pipe, 9 bearing caps, and camshafts.
HINT: Arrange the bearing caps in correct order for installation.
22. DISASSEMBLE EXHAUST CAMSHAFTS
(a) Mount the hexagon wrench head portion of the camshaft in a vise.
NOTICE: Be careful not to damage the camshaft.
(b) Using SST, turn the sub-gear clockwise, and remove the service bolt.
SST 09960-10010 (09962-01000, 09963-00500)
(c) Using snap ring pliers, remove the snap ring.
(d) Remove the wave washer.
(e) Remove the camshaft sub-gear.
(f) Remove the camshaft gear spring.
HINT: Arrange the camshaft sub-gears and gear spring (RH and LH sides).
NOTICE: Be careful not to damage the camshaft timing tube.
23. REMOVE OIL SEAL FROM INTAKE CAMSHAFT
24. REMOVE SPARK PLUGS
25. REMOVE CYLINDER HEAD AND EXHAUST MANIFOLD ASSEMBLIES
(a) Uniformly loosen the 10 cylinder head bolts on one side of each cylinder head in a little at a time for several times as in the sequence shown, then do the other side as shown. Remove the 20 cylinder head bolts and the plate washers.
NOTICE:
- Removing the bolts in incorrect order could cause a warp or cracks in the cylinder head.
- Do not drop the plate washer of the cylinder head bolt into A area in the illustration. It will fall down to the oil pan through the cylinder head and the cylinder block.
(b) Lift the cylinder head from the dowels on the cylinder block, and place the 2 cylinder heads on wooden blocks.
HINT: After lifting off the cylinder head, pry off the cylinder head and the cylinder block with a screwdriver.
NOTICE:
- Be careful not to damage the contact surfaces of the cylinder head and the cylinder block.
- The cylinder head should not be tilted so to secure the valve lifter. If the cylinder head is tilted, remove the valve lifter and check that the adjusting shim is set correctly.
26. REMOVE RH EXHAUST MANIFOLD FROM CYLINDER HEAD
(a) Remove the 4 bolts and the heat insulator.
(b) Remove the 8 nuts, the exhaust manifold and the gasket.
27. REMOVE LH EXHAUST MANIFOLD FROM CYLINDER HEAD
(a) Remove the 4 bolts and the heat insulator.
(b) Remove the 8 nuts, the exhaust manifold and the gasket.
