• Air regulator 07AAJ-PNAA100
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.

9. Move the intake secondary rocker arm (A) for the
No. 1 cylinder. The primary rocker arm (B) and
secondary rocker arm should move together.
If the intake primary 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.
10. Remove the tools.
11. Tighten the rocker shaft bolts to 24 N·m (2.4 kgf·m,
17 lbf·ft).
12. Install the cylinder head covers (see page 6-34).
1. Remove the cylinder head cover (see page 6-34).
2. Set the No. 1 piston at TDC (see step 2 on page 6-
15).
3. Push on the intake mid rocker arm (A) for the No. 1
cylinder. The mid rocker arm should move
independently of the primary rocker arm (B) and
secondary rocker arm (C).
• If the intake mid rocker arm does not move,
remove the mid, primary, and secondary intake
rocker arms as an assembly, and check that the
pistons in the mid and primary rocker arms move
smoothly.
If any rocker arm needs replacing, replace the
primary, mid and secondary rocker arms as an
assembly, and retest.
• If the mid rocker arm moves freely, go to step 4.
4. Repeat step 3 on the remaining intake mid rocker
arms with each piston at TDC. When all the mid
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 pistons A and B do not
move after applying air pressure, move the primary
or secondary rocker arm up and down manually.
9. Make sure that the intake primary rocker arm (A)
and intake secondary rocker arm (B) are
mechanically connected by the piston and that the
mid rocker arm (C) does not move when pushed
manually. If any intake mid rocker arm moves
independently of the primary and secondary rocker
arms, replace the rocker arms as a set.
10. Remove the tools.
11. Tighten the rocker shaft bolts to 24 N·m (2.4 kgf·m,
17 lbf·ft)
12. Install the cylinder head covers (see page 6-34).

1. Remove the cylinder head covers (see page 6-34).
2. Set the No. 1 piston at top dead center (TDC). Align
the pointer (A) on the front upper cover with the
No. 1 piston TDC mark (B) on the front camshaft
pulley.
3. Select the correct thickness feeler gauge for the
valves you’re going to check.
4. Insert the feeler gauge (A) between the adjusting
screw (B) and the end of the valve stem and slide it
back and forth; you should feel a slight amount of
drag.
5. If you feel too much or too little drag, loosen the
locknut (A), and turn the adjusting screw (B) until
the drag on the feeler gauge is correct.
6. Tighten the locknut and recheck the clearance.
Repeat the adjustment, if necessary.
