9. SET NO. 1 CYLINDER TO TDC/COMPRESSION





a) Turn the crankshaft pulley, and align its groove with the timing mark 0 of the timing chain cover.
b) Check that the timing marks of the camshaft timing gear and camshaft timing sprocket are aligned with the timing marks of the bearing caps as shown in the illustration.
c) Place paint marks on the timing chain.
10. REMOVE CHAIN TENSIONER ASSY NO.1





a) Remove the 2 nuts, tensioner and gasket.

NOTICE: Do not revolve the crankshaft without the tensioner.

11. REMOVE NO.2 CAMSHAFT





a) Fix the camshaft with a wrench, and then loosen the bolt.





b) Loosen and remove the bearing cap bolts on No. 2 camshaft in the sequence shown in the illustration in several passes, and remove the 5 bearing caps.





c) Raise the No. 2 camshaft and remove it. Then remove the sprocket bolt.
d) Disconnect the camshaft timing sprocket (with the timing chain) from the No. 2 camshaft.
e) Remove the camshaft timing sprocket from the timing chain.
12. REMOVE CAMSHAFT





a) Loosen the bearing cap bolts on camshaft in the sequence shown in the illustration in several passes, and remove the caps.
b) Remove the camshaft.





c) Tie the timing chain with a string.

NOTICE: Do not drop anything inside the timing chain cover.

13. REMOVE CAMSHAFT TIMING GEAR ASSY





a) Fix the No. 1 camshaft with a vise, and make sure that the camshaft timing gear does not rotate.
b) Cover all the paths with vinyl tape except the advanced side path shown in the illustration.





c) Using an air gun, apply about 150 kPa (1.5 kgf-cm, 21 psi) of air pressure to the port on the advanced angle side.

CAUTION: Some oil spraying will occur. Contain the spray with a shop rag.

HINT: This operation releases the lock pin for the extreme retarded angle lock.

d) Under the condition above, check that the camshaft timing gear can be turned by hand to the advanced angle side (counterclockwise), the direction of the arrow in the illustration.
Standard: Can be turned

HINT: The camshaft timing gear will turn to the advanced angle side without applying force by hand depending on the force of the air pressure applied. Also, if applying pressure to the oil path is difficult as a result of air leakage from the port, the lock pin may be difficult to release.





e) Remove the fringe bolt from the camshaft timing gear.

NOTICE:
^ Be sure not to remove the other 4 bolts.
^ If planning to reuse the camshaft timing gear assembly, release the straight pin lock first, and then install the gear.

14. INSTALL CAMSHAFT TIMING GEAR ASSY





a) Put the camshaft timing gear against the camshaft .
b) Turn the camshaft timing gear (in the direction shown in the illustration) while pushing it lightly against the camshaft. Push further at the position where the pin gets into the groove.

NOTICE: Be sure not to turn the camshaft timing gear to the retarded angle side (to the right direction).

c) Check that there is no clearance between the gear's fringe and the camshaft.
d) Tighten the fringe bolt with the camshaft timing gear fixed.
Torque: 54 Nm (551 kgf-cm, 40 ft. lbs.)
e) Check that the camshaft timing gear can move to the retarded angle side (to the right direction) and is locked at the extreme retarded angle.
15. INSTALL CAMSHAFT





a) Install the timing chain on the camshaft timing gear, with the painted mark of the link aligned with the timing marks of the camshaft timing gear.





b) Examine the front marks and numbers of the 5 bearing caps and install them. Then install the 10 bearing cap bolts. Uniformly tighten the bolts in the sequence shown in the illustration.
Torque: 30 Nm (301 kgf-cm, 22 ft. lbs.) for bearing cap No. 1
9.0 Nm (92 kgf-cm, 80 inch lbs.) for bearing cap No. 3
16. INSTALL NO.2 CAMSHAFT





a) Put the camshaft on the cylinder head with the painted mark of the link of chain aligned with the timing mark of the camshaft timing sprocket.





b) Raise the camshaft and temporarily tighten the sprocket bolt.





c) Examine the front marks and numbers of the 5 bearing caps and install them. Then install the 10 bearing cap bolts. Uniformly tighten the bolts in the sequence shown in the illustration.
Torque: 30 Nm (301 kgf-cm, 22 ft. lbs.) for bearing cap No. 2
9.0 Nm (92 kgf-cm, 80 inch lbs.) for bearing cap No. 3





d) Fix the camshaft with a wrench, and then tighten the sprocket bolt.
Torque: 54 Nm (551 kgf-cm, 40 ft. lbs.)

NOTICE: Be careful not to damage the valve lifter.





e) As shown in the illustration, check the paint marks of the timing chain, camshaft timing gear and camshaft timing sprocket and the alignment of the pulley groove with timing mark of the chain cover.
17. INSTALL CHAIN TENSIONER ASSY NO.1





a) Raise the ratchet pawl, fully push in the plunger and apply the hook to the pin so that the plunger cannot spring out.





b) Install a new gasket and the chain tensioner with the 2 nuts.
Torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)

NOTICE: When installing the tensioner, set the hook again if the hook releases the plunger.





c) Turn the crankshaft counterclockwise and check that the plunger knock pin is disconnected from the hook.





d) Turn the crankshaft clockwise and check that the slipper is pushed by the plunger.
18. INSTALL CYLINDER HEAD COVER SUB-ASSY





a) Remove any old packing (FIPG) material.
b) Apply seal packing to 2 locations as shown in the illustration.
