Removal

Removal

1. Timing chain/belt cover SUB-ASSY removal
2. Chain SUB-ASSY removal (bank 1 side)
(1) Attach the SST to the crankshaft.
SST 18252AA000





(2) Turn the crankshaft using the SST to align the alignment marks of crankshaft timing gear/sprocket, camshaft timing intake gear ASSY RH and camshaft timing exhaust gear ASSY RH.

NOTE:
At this time, the crankshaft timing gear key faces downward.





(3) Push down the chain tensioner slipper as shown in the figure and secure the plunger by inserting a 2.5 mm {0.098 in} dia. hex wrench into the holes of chain tensioner ASSY NO. 1 and stopper plate.





(4) Remove the two bolts and remove the chain tensioner ASSY NO. 1.
(5) Remove the chain tensioner slipper.





(6) Remove the bolt and remove the chain vibration damper NO. 1.
(7) Remove the chain SUB-ASSY.

CAUTION:
When the chain SUB-ASSY is removed, the valve heads contact each other and the valve stems may bend. Do not turn the intake camshaft RH and exhaust camshaft RH to the outside of the range of zero-lift (in range where they can be turned lightly by hand).

NOTE:
The removed parts must be organized by installation location.





3. Chain SUB-ASSY removal (bank 2 side)
(1) Attach the SST to the crankshaft.
SST 18252AA000
(2) Turn the crankshaft using the SST to align the alignment marks of crankshaft timing gear/sprocket, camshaft timing intake gear ASSY LH and camshaft timing exhaust gear ASSY LH.

(3) Push up the chain tensioner slipper as shown in the figure and secure the plunger by inserting a wire (with a diameter of approx. 1 mm {0.039 in}) into the holes of chain tensioner ASSY NO. 2 and stopper plate.





(4) Remove the two bolts and remove the chain tensioner ASSY NO. 2.
(5) Remove the chain tensioner slipper.





(6) Remove the O-ring from the cylinder block (bank 2 side).





(7) Remove the bolt and remove the chain vibration damper NO. 1.
(8) Remove the chain SUB-ASSY.

CAUTION:
^ When the chain SUB-ASSY is removed, the valve heads contact each other and the valve stems may bend. Do not turn the exhaust camshaft LH to the outside of the range of zero-lift (in range where they can be turned lightly by hand).
^ At this time, the No. 1 piston and No. 4 piston are located near the TDC of compression stroke. If the intake camshaft LH is turned, the valve and the piston may contact and valve stem may bend. Do not turn the intake camshaft LH.

NOTE:
The removed parts must be organized by installation location.

(9) Remove the SST from the crankshaft.
