Camshaft lock pin set 07AAB-RWCA120
NOTE: Keep the cam chain away from magnetic fields.
 Before doing this procedure, check that the variable valve timing control (VTC) actuator is locked by
turning the VTC actuator counterclockwise. If not
locked, turn the VTC actuator clockwise until it stops,
then recheck it. If it is still not locked, replace the VTC
actuator.
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
2. Set the camshafts to TDC. The punch mark (A) on the VTC actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. To hold the intake camshaft, insert a camshaft lock
pin (07AAB-RWCA120) (A) into the maintenance
hole in camshaft position (CMP) pulse plate A (B)
and through No. 5 rocker shaft holder (C).
4. To hold the exhaust camshaft, insert a camshaft lock pin (A) into the maintenance hole in CMP pulse
plate B (D) and through No. 5 rocker shaft holder
(C).
5. Install the cam chain on the crankshaft sprocket with the colored link plate (A) aligned with the mark
(B) on the crankshaft sprocket.

cam chain. Remove the pin from the auto-tensioner.
Turn the plate (A) counterclockwise, to release the
lock, then press the rod (B), and set the first cam (C)
to the first edge of the rack (D). Insert the 1.2 mm
(0.05 in.) diameter pin (E) into the holes (F).
NOTE: If the chain tensioner is not set up as
described, the tensioner will be damaged.

16. Clean, and dry the chain case mating surfaces.
17. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the engine
block mating surface of the chain case, and to the
inside edge of the threaded bolt holes. Install the
component within 5 minutes of applying the liquid
gasket.
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
 If too much time has passed after applying the liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket.
18. Apply liquid gasket to the engine block upper surface contact areas (A) on the chain case and
lower block upper surface contact areas (B) on the
chain case.
19. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the oil pan
mating surface of the chain case, and to the inside
edge of the threaded bolt holes. Install the
component within 5 minutes of applying the liquid
gasket.
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be install within 4 minutes.
 If too much time has passed after applying the liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket. 20. Install the new O-ring (A) on the chain case. Set the
edge of the chain case (B) to the edge of the oil pan
(C), then install the chain case on the engine block
(D). Wipe off the excess liquid gasket on the oil pan
and chain case mating surface.
NOTE: When installing the chain case, do not slide the bottom surface onto the oil pan mounting surface.
