HINT:

If the marks are not aligned, turn the crankshaft again to align the marks.

Place paint marks on the timing marks and sprockets of each camshaft timing gear and on the links of the No. 1 chain.

HINT:

Be sure to place the paint marks on 2 links of the chain and on the sprockets of the camshaft timing gears at the locations of the timing marks of the camshaft timing gears.

Turn the crankshaft approximately 30° counterclockwise so that there is some slack in the chain.

HINT:

This prevents the valves and pistons from interfering with each other.

Remove the 2 bolts and chain tensioner.

NOTICE:

Do not drop the No. 1 chain tensioner assembly or bolts into the timing chain cover.

Turn the crankshaft clockwise until it is in the position shown in the illustration so that there is some slack in the chain between the banks.

CAUTION:

As the camshafts turn suddenly, do not touch the camshafts or camshaft timing gears.

NOTICE:

When turning the crankshaft, engine oil may spray out of the oil holes.

Turn the crankshaft clockwise until it is in the position shown in the illustration so that the chain can be removed easily.

NOTICE:

When turning the crankshaft, engine oil may spray out of the oil holes.

Remove the chain from the sprocket of the camshaft timing gear and set it on the gear.

CAUTION:

As the camshaft may turn suddenly and pinch your fingers when the chain is removed, pinch the chain and lift it upward to remove it from the sprocket.

Remove the bolts and bearing caps in the order shown in the illustration. Immediately after removing a bearing cap, install bolts and washers for temporary installation of the camshaft housing in the order shown in the illustration.

Torque:

10 N*m{102 kgf*cm, 7 ft.*lbf}

NOTICE:

1. Do not install the bearing caps when installing bolts and washers for temporary installation of the camshaft housing.
   
2. Be sure to follow the numerical order when performing this procedure.
   
3. Do not allow bolts and washers for temporary installation of the camshaft housing to contact the camshaft.
   
4. Do not drop bolts and washers for temporary installation of the camshaft housing into the cylinder head.
   

HINT:

1. Arrange the removed parts so that they can be reinstalled in their original locations.
   
2. Part number of bolt for temporary installation of camshaft housing: 91551-G0845 (quantity: 8)

Remove the bolt of the No. 2 chain tensioner assembly.

Remove the No. 2 chain tensioner assembly while lifting up the No. 2 camshaft.

While lifting up the No. 2 camshaft, pass it through the No. 2 chain and pull it out towards the front of the vehicle to remove it.

Lift up the rear of the camshaft so that it is at an angle.

Remove the chain from the camshaft timing gear and pull out the camshaft and No. 2 chain towards the rear of the vehicle to remove them.

NOTICE:
