Rocker Arm Assembly: Testing and Inspection
VTEC Rocker Arm Test
VTEC Rocker Arm Test
Special Tools Required
Air pressure regulator 07AAJ-PNAA100
1. Start the engine, and let it run for 5 minutes, then turn OFF the ignition switch.
2. Remove the cylinder head cover.
3. Set the No. 1 piston at top dead center (TDC).
4. Move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A should move independently of the secondary rocker
arm B.
^
If the intake secondary rocker arm A moves freely, go to step 5.
^
If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, then check that the pistons in the
secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, and retest.
5. Repeat step 4 on the remaining intake secondary rocker arms with each piston at TDC. When all the secondary rocker arms pass the test, go to step
6.
6. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4 kgf/cm2, 57 psi).
7. Inspect the valve clearance.
8. Install a 10 x 1.0 mm adapter to the inspection hole, then connect the air pressure regulator.
9. Loosen the valve on the regulator, and apply the specified air pressure.
Specified Air Pressure: 290 kPa (3.0 kgf/cm2, 42 psi)
