REPLACEMENT
Remove cylinder head cover sub-assy
9. SET No. 1 CYLINDER TO TDC/COMPRESSION
Set No. 1 Cylinder to TDC/compression
10. REMOVE CHAIN TENSIONER ASSY No.1
a. Remove the 2 nuts, tensioner and gasket.
NOTICE: Be sure not to revolve the crankshaft without the tensioner.
Remove chain tensioner assy No.1
11. REMOVE CAMSHAFT SUB−ASSY, No.2
a. Fix the camshaft with a wrench and then loosen the sprocket bolt.
NOTICE: Be careful not to damage the valve lifter.
b. Uniformly loosen and remove the No. 2 camshaft’s 10 bearing cap bolts in the sequence shown in the illustration.
Then remove the 5 bearing caps.
12. REMOVE 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
c. Using an air gun, apply about 150 kPA (1.5kgf/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 (counterclokΩise), the direction of the arrow in the illustration.
Standard: Must turn
HINT: The camshaft timing gear will turn to the advanced angle side without applying foce 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.

14. INSTALL CAMSHAFT TIMING GEAR ASSY
NOTICE: Be sure not to turn the camshaft timing gear to the retarded angle side (to the right direction).
Torque: 54 N·m (551 kgf·cm, 40 ft·lbf)
Install camshaft timing gear assy
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 sprocket.
b. Examine the front marks and unmbers 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 N·m (301 kgf·cm, 22 ft·lbf) for bearing cap No. 1 9.0 N·m (92 kgf·cm, 80 in.·lbf) 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. Raising the camshaft, temporarily tighten the sprocket bolt.
c. Examine the front marks and unmbers 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 N·m (301 kgf·cm, 22 ft·lbf) for bearing cap No. 2 9.0 N·m (92 kgf·cm, 80 in.·lbf) for bearing cap No. 3
d. Fix the camshaft with a wrench, and then tighten the sprocket bolt.
Torque: 54 N·m (551 kgf·cm, 40 ft·lbf)
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. Release 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 N·m (92 kgf·cm, 80 in.·lbf)
NOTICE: When installing the tensioner, set the hook again if the hook releases the plunger.
c. Turn the crankshaft counterclockΩise and check that the plunger knock pin is disconnected from the hook.
d. Turn the crankshaft clockΩise and check that the slipper is pushed by the plunger.
18. INSTALL CYLINDER HEAD COVER SUB−ASSY
Seal packing: Part No. 08826−00080 or equivalent
NOTICE:
c. Install the cylinder head cover with the 8 bolts and 2 nuts.
Torque: 11 N·m (110 kgf·cm, 8 ft·lbf)
