1. Remove the cylinder head covers (see page 6-34).
2. Set the No. 1 piston at top dead center (TDC) (see
step 2 on page 6-15).
3. Move the intake secondary rocker arm (A) for the
No. 1 cylinder. The secondary rocker arm should
move independently of the primary rocker arm (B).
• If the intake secondary rocker arm does not move,
remove the primary and secondary intake rocker
arms as an assembly, and check that the piston
in the primary rocker arm moves smoothly.
If any rocker arm needs replacing, replace the
primary and secondary rocker arms as an
assembly, and retest.
• If the secondary rocker arm moves freely, go to
step 4.
4. Repeat step 3 on the remaining intake secondary
rocker arms with each piston at TDC. When all the
secondary rocker arms pass the test, go to step 5.
5. Check that the air pressure on the shop air
compressor gauge indicates over 690 kPa (7.0
kgf/cm , 100 psi).
6. Inspect the valve clearance (see page 6-15).
7. Remove the two end intake rocker shaft mounting
bolts, then install and connect the special tools as
shown.
8. Loosen the valve on the regulator and apply the
specified air pressure.
NOTE: If the synchronizing piston does not move
after applying air pressure; move the primary or
secondary rocker arm up and down manually by
rotating the crankshaft clockwise.
