PROCEDURE
INSTALL NO. 2 CAMSHAFT BEARING
INSTALL NO. 1 CAMSHAFT BEARING
INSPECT CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY
| *a | Knock Pin |
| *b | Knock Pin Hole |
Align and fit the knock pin of the No. 2 camshaft to the knock pin hole of the camshaft timing exhaust gear assembly.
| *a | Hexagonal Portion |
Using SST, grip the hexagonal portion, and then secure the SST and No. 2 camshaft in a vise as shown in the illustration and check that the camshaft timing exhaust gear assembly does not rotate.
Note
Do not damage the No. 2 camshaft.
Never grip areas other than the hexagonal portion, as this may cause damage.
| *1 | Camshaft Timing Exhaust Gear Assembly |
| *2 | Camshaft Flange |
| *a | Incorrect |
| *b | Correct |
| *c | Clearance |
| *d | No Clearance |
Check that there is no clearance between the camshaft timing exhaust gear assembly and camshaft flange.
While securely holding the No. 2 camshaft, install the bolt of the camshaft timing exhaust gear assembly by hand.
Note
Do not disassemble the camshaft timing exhaust gear assembly.
Tech Tips
Perform inspection after repair after replacing the camshaft timing exhaust gear assembly.
Check the lock of the camshaft timing exhaust gear assembly.
Make sure that the camshaft timing exhaust gear assembly is locked.
Note
Be careful not to damage the No. 2 camshaft.
Release the lock pin.
| *a | Retard Side Path | *b | Advance Side Path |
| *c | Open | *d | Close |
| *e | Rubber Piece | *f | Vinyl Tape |
| *g | Knock Pin | - | - |
Clean the camshaft journal with non-residue solvent.
Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.
Tech Tips
There are 4 oil paths in the grooves of the No. 2 camshaft. Plug 3 of the oil paths with rubber pieces.
Make a hole in the tape over the port (A) shown in the illustration.
While applying approximately 200 kPa (2.0 kgf/cm2, 29 psi) of air pressure to the oil path, forcibly turn the camshaft timing exhaust gear assembly in the advance direction (counterclockwise).
CAUTION:
Cover the oil paths with a piece of cloth when applying air pressure to prevent oil from spraying.
Note
Do not allow the camshaft timing exhaust gear assembly to lock. If it locks, release the lock pin again.
Tech Tips
Depending on the air pressure applied, the camshaft timing exhaust gear assembly may turn in the advance direction without assistance by hand.
If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.
Check for smooth rotation.
Turn the camshaft timing exhaust gear assembly within its movable range (26.5 to 28.5°) 2 or 3 times, but do not turn it to the most retarded position. Make sure that the camshaft timing exhaust gear assembly turns smoothly.
Note
Do not use air pressure to perform the smooth operation check.
Do not allow the camshaft timing exhaust gear assembly to lock. If it locks, release the lock pin again.
Remove the vinyl tape and rubber pieces from the No. 2 camshaft.
Remove the bolt and camshaft timing exhaust gear assembly.

Make sure that the No. 1 valve rocker arm sub-assemblies are installed as shown in the illustration.
Clean the camshaft journals.
Apply a light coat of engine oil to the camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.
| *a | Approximately 17° |
| *b | Knock Pin |
Install the camshaft to the camshaft housing sub-assembly as shown in the illustration.
INSTALL CAMSHAFT BEARING CAP
Confirm the marks and numbers on the No. 2 camshaft bearing cap and 3 No. 3 camshaft bearing caps and place them and the No. 1 camshaft bearing cap in their proper positions and directions.
Uniformly tighten the 10 bolts in several steps in the order shown in the illustration.
| *1 | No. 1 Camshaft Bearing Cap |
| *2 | No. 2 Camshaft Bearing Cap |
| *3 | No. 3 Camshaft Bearing Cap |
Uniformly tighten the 11 bolts in several steps in the order shown in the illustration.
Check the torque of each bolt again.
INSTALL CAMSHAFT TIMING GEAR ASSEMBLY
| *a | Advanced Position |
| *b | Retarded Position |
| *c | Knock Pin Hole |
| *d | Alignment Mark |
Check the camshaft timing gear assembly position.
Note
If the camshaft timing gear assembly is set to the advanced position, do not let the camshaft timing gear assembly rotate clockwise during installation.
If the camshaft timing gear assembly has rotated to the most retarded position, make sure to release the lock pin and set the camshaft timing gear assembly to the most advanced position before tightening the camshaft timing gear assembly.
| *a | Narrow |
| *b | Wide |
Install the camshaft timing gear assembly as shown in the illustration.
| *a | Narrow |
| *b | Wide |
Turn the camshaft timing gear assembly approximately 180° counterclockwise.

| *c | Gap |
| *d | No Gap |
Check that there is no clearance between the camshaft timing gear assembly and camshaft flange.
While securely holding the camshaft, install the bolt of the camshaft timing gear assembly by hand.
Note
Do not use any tools to install the bolt. If the bolt is installed using a tool, the lock pin will be damaged.
If the lock pin has not been released, release it.
| *a | Make a Hole |
| *b | Adhesive Tape Sealing Area |
After cleaning the intake side VVT oil hole of the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.
Note
Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.
Make a hole in the adhesive tape as shown in the illustration.
Apply approximately 200 kPa (2.0 kgf/cm2, 29 psi) of air pressure to the open hole to release the lock pin.
Note
If air leaks out, reattach the adhesive tape.
Cover the hole with a piece of cloth when applying air pressure to prevent oil from spraying.
Forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).
Tech Tips
Depending on the air pressure applied, the camshaft timing gear assembly may turn in the advance direction without assistance by hand.
If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.
Remove the adhesive tape from the No. 1 camshaft bearing cap.
Using a wrench to hold the hexagonal portion of the camshaft, install the bolt.
Note
Be careful not to damage the cylinder head sub-assembly or spark plug tube with the wrench.
