9. Connector (VTC Oil Control Solenoid Valve A) - Disconnect


1.
Disconnect the connector (A).

2.
Remove the harness clip (B).

11. Cam Chain Case - Remove


12. Cam Chain Auto-Tensioner - Remove


1.
Loosely install the crankshaft pulley.

2.
Turn the crankshaft counterclockwise to compress the cam chain auto-tensioner.






3.
Rotate the crankshaft counterclockwise to align the holes on the lock (A) and the cam chain auto-tensioner (B).

4.
Insert a 1.2 mm (3/64 in) diameter pin (C) into the holes.

5.
Turn the crankshaft clockwise to secure the pin.

NOTE: If the holes in the lock and the cam chain auto-tensioner do not align, continue to rotating the crankshaft counterclockwise until the holes align, then install the pin.






6.
Remove the cam chain auto-tensioner (A) and the cam chain auto-tensioner filter (B).

NOTE: Check the cam chain auto-tensioner filter for damage. If filter is damaged, replace it.

7.
Remove the crankshaft pulley.

13. Cam Chain Guide B - Remove


14. Cam Chain - Remove


1.
Remove the cam chain guide (A), the cam chain tensioner arm (B), and the cam chain tensioner sub arm (C).

2.
Remove the cam chain.


NOTE:
Keep the cam chain away from magnetic fields.

1. No. 1 Piston at Top Dead Center - Set (Crank Side)

1.
Set the crankshaft to top dead center (TDC). Align the TDC mark (punch mark) (A) on the cam chain drive sprocket with the pointer (B) on the oil pump.

2. No. 1 Piston at Top Dead Center - Set (Cam Side)

1.
Set the No. 1 piston at top dead center (TDC). The "UP" mark (C) on VTC actuator A should be at the top and align the TDC marks (D) on VTC actuator A and VTC actuator B.

3. Pin - Insert

1.
Insert the camshaft lock pin set to camshaft maintenance holes.

4. Cam Chain - Install

1.
Install the cam chain on the cam chain drive sprocket with the punch mark (A) aligned with the center of the colored link plates (B).





Intake

Exhaust
2.
Install the cam chain on VTC actuator A and VTC actuator B with the punch marks (C) aligned with the center of the colored link plates (D).

5. Cam Chain Tensioner Arm, Cam Chain Tensioner Sub Arm, and Cam Chain Guide - Install

1.
Install the cam chain guide (A), the cam chain tensioner arm (B), and the cam chain tensioner sub arm (C).

6. Cam Chain Guide B - Install


7. Pin - Remove

1.
Remove the camshaft lock pin set from the camshaft maintenance holes.

8. Cam Chain Auto-Tensioner - Install

1.
Compress the cam chain auto-tensioner when replacing the cam chain. Remove the pin (A) from the cam chain auto-tensioner that was installed during removal. Turn the plate (B) counterclockwise, to release the lock, then press the rod (C), and set the first cam (D) to the first edge of the rack (E). Insert the 1.2 mm (3/64 in) diameter pin back into the holes (F).

NOTE: If the cam chain auto-tensioner is not set up as described, the cam chain auto-tensioner will be damaged.





2.
Install the cam chain auto-tensioner filter (A) and the cam chain auto-tensioner (B).





3.
Remove the pin (A) from the cam chain auto-tensioner.

9. Cam Chain Case - Install



1.
Check the pulley end crankshaft oil seal for damage. If the oil seal is damaged, replace the pulley end crankshaft oil seal.

2.
Apply liquid gasket to the engine block, the cylinder head, and the oil pan mating surface of the cam chain case and to the inside edge of the threaded bolt holes.

3.
Set the edge of the cam chain case (A) to the edge of the oil pan (B), then install the cam chain case on the engine block (C). Wipe off the excess liquid gasket on the oil pan and the cam chain case mating area.

NOTE: When installing the cam chain case, do not slide the bottom surface onto the oil pan mounting surface.

11. Connector (VTC Oil Control Solenoid Valve A) - Connect


1.
Install the harness clip (A).

2.
Connect the connector (B).

4. Cam Chain - Inspect


1.
Measure the length of the cam chain auto-tensioner rod.

Cam Chain Auto-Tensioner Rod Length
Standard (New):
20.0 mm (0.787 in)
Service Limit:
23.9 mm (0.941 in)

2.
If the length is over the service limit, replace the cam chain. When replacing, check the teeth on the cam chain drive sprocket, VTC actuator A, and VTC actuator B for wear and damage. If any of them are worn or damaged, replace if necessary.

3.
Check the oil passage on the cam chain auto-tensioner for clogs. If the cam chain auto-tensioner is clogged, replace it.

5. All Removed Parts - Install

1.
Install the parts in the reverse order of removal.
