NOTICE
• Check that the following conditions are met before using the
air supply (special tool). The following conditions are
essential for use of the air supply, as the specified air
pressure of 290 kPa (3.0 kgf/cm
at the gauge of the tool. Stop using the other air tools unless
the specified air pressure is maintained.
– Check whether the air compressor tank is under the
specified air pressure and the tank gauge shows the value
of the set pressure.
– Connect the air supply to the air intake port located close to
the compressor.
– Check as quickly as possible (within 6 seconds), or the air
pressure drops possibly marking it hard to switch the valve
timing to the high lift side.
• Check on each cylinder with the piston at the top dead center
of its compression stroke.
• Oil can spurt out when the air pressure is applied. Adjust the
air pressure with the regulator valve (special tool) and
increase the air pressure gradually.
4) Remove the 10 mm sealing bolt from the No.1 camshaft
holder and install the air stopper (special tool).
5) Remove the two mounting bolts of the No.2 and No.3
camshaft holders (intake side), and install the special tool
as shown.
TOOLS:
Air supply
VTEC air adapter
VTEC air stopper
Air joint adapter
NOTICE
Install the VTEC air adapter (special tool) and tighten it by
hand.
6) Apply the specified air pressure and check that the valve
timing switched to the high lift side.
Air pressure: 290 kPa (3.0 kgf/cm
7) Check that the three intake rocker arms are interconnected
by applying the specified amount of air pressure. Move the
secondary rocker arm up and down with a finger and check
that both the mid rocker arm and the primary rocker arm
move up and down, too.
8) If there is abnormality in the rocker arm movement, replace
the intake rocker arm as an assembly.
9) Remove the VTEC air adapter (special tool) and tighten the
camshaft holder mounting bolts to the specified torque.
TORQUE: 22 N . m (2.2 kgf . m, 16 lbf . ft)
10) Remove the air stopper (special tool) from the No.1
camshaft holder, and tighten the 10 mm sealing bolt to the
specified torque.
TORQUE: 20 N . m (2.0 kgf . m, 14 lbf . ft)
11) Install the cylinder head cover (P. 10-40).
12) Check that the MIL does not come ON.
