REMOVE CAMSHAFT TIMING GEAR OR SPROCKET

1. 

   Turn the crankshaft pulley, and align its groove with the "0" timing mark of the timing chain cover.

2. Check that the timing marks of the camshaft timing gear assembly and camshaft timing gear or sprocket are aligned with the timing marks of the No. 1 bearing cap as shown in the illustration.

   Table 2. Text in Illustration

   *a	Timing Mark
   *b	Groove

   Tip:

   If the timing marks do not align, rotate the crankshaft clockwise again and align the timing marks.

3. 

   Place paint marks on the timing chain, camshaft timing gear assembly and camshaft timing gear or sprocket.

   Table 3. Text in Illustration

   *a	Paint Mark
   *b	Timing Mark

4. 

   Hold the camshaft with a wrench and loosen the camshaft timing gear or sprocket bolt.

   Table 4. Text in Illustration

   *a	Hold
   *b	Loosen

   Note:

   Be careful not to damage the oil delivery pipe.

5. 

   Using a 10 mm socket hexagon wrench, remove the timing chain cover plug.

6. 

   Using a screwdriver, access the tensioner stopper plate through the chain tensioner service hole. Move the stopper plate upward to release the lock. Then hold the plate in that position as shown in the illustration.

   Table 5. Text in Illustration

   *a	Stopper Plate

   Tip:

   If the lock of the stopper plate is difficult to release, slightly rotate the hexagonal part of the camshaft to the left and right.

7. 

   With the lock of the stopper plate released, slightly rotate the camshaft clockwise and keep it in that position.

   Table 6. Text in Illustration

   *1

   Plunger

   Note:

   Be careful not to damage the oil delivery pipe.

   Tip:

   Rotating the camshaft clockwise will cause pressure to be applied to the tensioner plunger.

8. 

   Remove the screwdriver from the chain tensioner service hole. Move the stopper plate to the position shown in the illustration. Then insert a hexagon wrench into the hole.

   Table 7. Text in Illustration

   *a	Hexagon Wrench

   Tip:
   

   • If the wrench cannot fit into the hole, slightly rotate the camshaft counterclockwise, and then clockwise. Then insert the wrench.

   • To prevent the wrench from falling out, use tape to fix the wrench in place.

9. 

   Remove the camshaft timing gear or sprocket bolt and camshaft timing gear or sprocket from the No. 2 camshaft.

REMOVE CAMSHAFT

1. 

   Uniformly loosen the 21 bearing cap bolts in several passes in the sequence shown in the illustration.

2. Remove the 9 bearing caps, oil delivery pipe, O-ring and No. 2 camshaft.

   Note:
   

   • Uniformly loosen the bolts while keeping the camshafts level.

   • Do not pry the camshaft with a tool as an excessive amount of force may be applied to it.

3. 

   Remove the camshaft while holding the timing chain.

4. 

   Secure the timing chain with a string as shown in the illustration.

   Note:

   Be careful not to drop anything inside the timing chain cover.

REMOVE NO. 1 VALVE ROCKER ARM SUB-ASSEMBLY

1. Remove the 16 No. 1 valve rocker arm sub-assemblies from the cylinder head sub-assembly.

   Tip:

   Arrange the removed parts in the correct order.

REMOVE VALVE LASH ADJUSTER ASSEMBLY

1. Remove the 16 valve lash adjuster assemblies from the cylinder head sub-assembly.

   Tip:

   Arrange the removed parts in the correct order.

INSPECT CAMSHAFT TIMING GEAR ASSEMBLY

1. Check the lock of the camshaft timing gear assembly.

   
   

   1. Mount the camshaft in a vise and confirm that the camshaft timing gear assembly is locked.

      Note:

      Do not damage the camshaft.

2. Release the lock pin.

   
   

   1. Clean the camshaft journal with non-residue solvent.

   2. 

      Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.

      Table 8. Text in Illustration

      *a	Retard Side Path
      *b	Advance Side Path
      *c	Open
      *d	Close
      	Rubber Piece
      	Vinyl Tape

      Tip:

      2 advance side paths are provided in the groove of the camshaft. Plug one of the paths with a rubber piece.

   3. Break through the tape over the advance side path, and then break through the tape over the retard side path on the opposite side from the hole over the advance side path as shown in the illustration.

   4. 

      Apply compressed air at approximately 200 kPa (2.0 kgf/cm², 28 psi) to the two paths accessible through the holes in the tape.

      Table 9. Text in Illustration

      *a	Retard Side Path
      *b	Advance Side Path

      CAUTION:

      Some oil splashing will occur. Cover the paths with a piece of cloth.

   5. 

      Check that the camshaft timing gear assembly revolves in the advance direction when reducing the air pressure applied to the retard side path.

      OK
      Gear rotates in the advance direction.

      Table 10. Text in Illustration

      *a	Retard Side Path
      *b	Advance Side Path
      *c	Decompress
      *d	Hold Pressure

      Tip:

      This operation releases the lock pin which holds the timing gear in the most retarded position.

   6. When the camshaft timing gear assembly reaches the most advanced position, release the air pressure from the retard side path and advance side path in that order.

      Note:

      Do not release the air pressure from the advance side path first. The gear may abruptly shift in the retard direction and break the lock pin.

3. Check for smooth rotation.

   
   

   1. Rotate the camshaft timing gear assembly within its movable range several times, but do not turn it to the most retarded position. Check that the gear rotates smoothly.

      CAUTION:

      Do not use air pressure to perform the smooth operation check.

4. Check the lock in the most retarded position.

   
   

   1. Confirm that the camshaft timing gear assembly becomes locked at the most retarded position.

REMOVE CAMSHAFT TIMING GEAR ASSEMBLY

1. Check that the camshaft timing gear assembly does not turn by mounting the hexagon wrench head portion of the camshaft in a vise through aluminum metal cap and so on.

   Note:

   Be sure not to damage the camshaft.

2. 

   Remove the flange bolt and camshaft timing gear assembly.

   Table 11. Text in Illustration

   *1	Flange Bolt
   *2	Straight Pin
   *a	Do Not Remove

   Note:
   

   • Be sure not to remove the other 3 bolts.

   • If planning to reuse the gear, be sure to release the straight pin lock before installing the gear.
