14. While holding the drive gear (A), turn the gear shaft (B) counterclockwise. Check that the drive
gear comes out to the other end. If the drive gear
does not move smoothly, replace the gear cover
assembly.
15. While holding the drive gear, turn the gear shaft clockwise. The gear shaft should turn freely. If the
gear shaft does not turn freely, replace the gear
cover assembly.
16. If the drive gear is worn or damaged, replace the overrunning clutch assembly; the gear is not
available separately.
Check the condition of the flywheel ring gear (M/T
model), or the torque converter ring gear (A/T
model) to see if the starter drive gear teeth are
damaged. 17. Install the brush into the brush holder, and set the
armature (A) in the brush holder (B).
NOTE: To seat the new brushes, slip a strip of 500
or 600 sandpaper, with the grit side up, between
the commutator and each brush, and smoothly turn
the armature. The contact surface of the brushes
will be sanded to the same contour as the
commutator.
18. While squeezing a spring (C), insert it in the hole on the brush holder, and push it until it bottoms.
Repeat this for the other three springs (D, E, and F).
19. Install the armature and the brush holder assembly into the housing.
NOTE: Make sure the armature stays in the holder.

1. Start the engine, and let it run for 5 minutes, then turn the ignition switch to LOCK (0).
2. Remove the cylinder head cover (see page 6-36).
3. Set the No. 1 piston at top dead center (TDC) (see step 5 on page 6-18).
4. Move the intake primary rocker arm (A) for the No. 1 cylinder. The primary rocker arm should
move independently of the intake secondary rocker
arm (B).
 If the intake primary rocker arm moves freely, go to step 5.
 If the intake primary rocker arm do not move independently, remove the primary and
secondary rocker arms as an assembly and check
that the pistons in the secondary and primary
rocker arms move smoothly. If any rocker arm
needs replacing, replace the primary and
secondary rocker arms as an assembly, then
retest. 5. Repeat step 4 on the remaining intake primary
rockerarmswitheachpistonatTDC.Whenallthe
primary 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/cm , 57 psi).
7. Inspect the valve clearance (see page 6-12).
8. Remove the sealing bolt (A) from the relief hole, and install the VTEC air stopper (B).
9. Remove the No. 2 and No. 3 camshaft holder bolts, and install the VTEC air adapters (C) finger-tight.
10. Connect the air joint adapter (D) and the air pressure regulator (E).
11. Loosen the valve on the air pressure regulator, and apply the specified air pressure.
NOTE: If the rocker arm piston does not move after
applying air pressure, move the primary or
secondary rocker arm up and down manually by
rotating the crankshaft clockwise.

3. Remove the camshaft holder:  K20Z2 engine (see step 3 on page 6-43)
 K20Z3 engine (see step 3 on page 6-44)
4. Remove the intake camshaft.
5. Check that the variable valve timing control (VTC) actuator is locked by turning the VTC actuator
counterclockwise. If not locked, turn the VTC
actuator clockwise until it stops, then recheck it. If it
is still not locked, replace the VTC actuator.
6. Seal the advance holes (A) and the retard holes (B) in the No. 1 camshaft journal with tape.
7. Punch a hole in the tape over one of the advance holes.
8. Apply air to the advance hole to release the lock. 9. Check that the VTC actuator moves smoothly. If the
VTC actuator does not move smoothly, replace the
VTC actuator.
10. Remove the tape and adhesive residue from the No. 1 camshaft journal.
11. Make sure the punch marks on the VTC actuator and the exhaust camshaft sprocket are facing up,
then set the camshafts in the rocker shaft holder:
 K20Z2 engine (see step 6 on page 6-61)
 K20Z3 engine (see step 6 on page 6-62)
12. Set the camshaft holders and cam chain guide B in place:
 K20Z2 engine (see step 7 on page 6-61)
 K20Z3 engine (see step 7 on page 6-62)
13. Tighten the camshaft holder bolts to the specified torque:
 K20Z2 engine (see step 8 on page 6-61)
 K20Z3 engine (see step 8 on page 6-62)
14. Hold the camshaft, and turn the VTC actuator clockwise until you hear it click. Make sure to lock
the VTC actuator by turning it.
15. Install the cam chain (see page 6-21).
16. Adjust the valve clearance:  K20Z2 engine (see page 6-12)
 K20Z3 engine (see page 6-14)

NOTE: Connect the Honda Diagnostic System (HDS) to
the data link connector (DLC) (see step 2 on page 11-3),
and monitor the engine coolant temperature (ECT)
sensor 1 with the HDS. Adjust the valve clearance only
when the engine coolant temperature is less than 38 °C
(100 °F).
1. Remove the cylinder head cover (see page 6-36).
2. Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control
