3.Rotate the crankshaft clockwise, and visually check all the primary rocker arms and secondary rocker arms moves freely.

  • If the primary rocker arm and secondary rocker arm moves together, remove the primary and secondary rocker arms as an assembly, and check that the pistons in the primary and secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the primary and secondary rocker arms as an assembly, and test.
  • If all the primary rocker arms and secondary rocker arms moves freely, go to 4.

4.Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4 kgf/cm2, 57 psi).

5.Inspect the valve clearance.

6.Remove the No. 3 rocker shaft mounting bolt, then install the VTEC air adapter (A) with a washer (thickness about 1.5 mm (0.06 in. )).

8.Install the VTEC adapter (C) to the VTEC air adapter, then connect the valve inspection set (D).

9.Loosen the valve on the regulator, and apply the specified air pressure.

Specified Air Pressure:
340 kPa (3.5 kgf/m2, 50 psi) 

10.With the specified air pressure applied, rotate the crankshaft clockwise, and visually check all the primary rocker arms and secondary rocker arms should move together.

  • If the primary rocker arm and secondary rocker arm moves freely, remove the primary and secondary rocker arms as an assembly, and check that the pistons in the primary and secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the primary and secondary rocker arms as an assembly, and test.

11.Remove the special tools.
