^ Air pressure regulator 07AAJ-PNAA100
^ VTEC air adapter 07VAJ-P8A010A
1. Remove the engine cover.
2. Remove the cylinder head cover.
3. Set the No. 1 piston at top dead center (TDC).
4. Move the primary rocker arm (A) for No. 1 cylinder. The primary rocker arm should move independently of the secondary rocker arm (B).
^ If the primary rocker arm does not move, remove the primary and secondary rocker arms as an assembly, and check that the piston in the secondary rocker arm moves smoothly.
^ If any rocker arm needs replacing, replace the primary and secondary rocker arms as an assembly.
5. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4 kgf/cm2, 57 psi).
6. Inspect the valve clearance.
7. Remove a rocker shaft mounting bolt (A), then connect the VTEC air adapter (B) and the VTEC air pressure regulator (C) to the bolt hole.
8. Loosen the valve on the regulator, and apply the specified air pressure.
Specified Air Pressure: 250 kPa (2.5 kgf/cm2, 36 psi)
9. With the specified air pressure applied and the piston at TDC, move the primary rocker arm (A). The primary rocker arm and secondary rocker arm (B) should move together. If the primary and secondary rocker arms do not move together, replace the rocker arms as a set.
10. Remove the special tools.
