CYLINDER HEAD (i) DISASSEMBLY/ASSEMBLY





1. Disassemble in the order indicated in the table.
2. Assemble in the reverse order of disassembly.

Camshaft Pulley Disassembly Note

Camshaft Disassembly Note
1. Before removing the camshaft cap, measure the camshaft end play.





2. Loosen the camshaft cap bolts a few turns in the order shown.
3. Before removing the camshaft, measure the camshaft journal oil clearance.

Cylinder Head Disassembly Note





- Loosen the cylinder head bolts a few turns in the order shown.

Cylinder Head Assembly Note





1. Tighten the cylinder head bolts a few turns in the order shown.
Tightening torque 17.2 - 22.0 Nm (1.75 - 2.25 kgf-m, 12.7 - 16.2 ft. lbs.)
2. Make paint marks on the bolt heads, as shown.





3. With the paint marks as a reference point, tighten the cylinder head bolts another 85° - 95° in the tightening order.
4. Then tighten them once again 85° - 95° in the tightening order.

Seal Cap Assembly Note





- Apply silicone sealant to the seal cap as shown.
Thickness 3 - 4 mm (0.12 - 0.15 inch)

Camshaft Assembly Note

Caution: Because there Is little camshaft thrust clearance, the camshaft must be hold horizontally while it is Installed. Otherwise, excessive force will be applied to the thrust area, causing burr on the thrust receiving area of the cylinder head journal. To avoid this, the following procedure must be observed.





1. Assemble camshaft onto the cylinder head, facing the cam noses at No. 1 and No.3 cylinder as shown.





2. Apply silicone sealant as shown.
Thickness 1 mm (0.04 inch)
3. Hand tighten the camshaft cap bolts marked 2, 4, 5, and 7.

Camshaft Bearing Cap Tightening Sequence:

4. Install the camshaft cap bolts and tighten them a few turns in the order shown. Verify that the camshaft goes down horizontally while tightening the two camshaft cap installation bolts to the No.3 journal.
5. Apply clean engine oil to the new oil seal.
6. Push the oil seal slightly in by hand.





7. Tap the oil seal into the cylinder head using the SST and a hammer.

Camshaft Pulley Assembly Note





1. Install the camshaft pulleys, with the "I" mark (IN side) or "E" mark (EX side) straight up.





2. Hold the camshaft using a suitable wrench on the cast hexagon as shown.
