NOTE:
When installing oil seal (1), press-fit it till its end face is flush
with oil pump case (2) end face.

Check outer and inner rotors, rotor plate, and oil pump case for
excessive wear or damage.
MEASUREMENT

Radial clearance
Check radial clearance between outer rotor (1) and case, using
thickness gauge.
If clearance exceeds its limit, replace outer rotor or case.
Limit on radial clearance between outer rotor and case:
0.200 mm (0.079 in.)

Side clearance
Using straight edge and thickness gauge, measure side clear-
ance.
Limit on side clearance: 0.10 mm (0.0039 in.)
ASSEMBLY
1) Wash, clean and then dry all disassembled parts.
2) Apply thin coat of engine oil to inner (2) and outer rotors (1), oil
seal lip portion, and inside surfaces of oil pump case and plate.
3) Install outer and inner rotors to pump case.

(a): 130 N
.m (13.0 kg-m, 94.0 lb-ft)
6) Install timing belt, tensioner, oil pump strainer, oil pan and other
parts as previously outlined.
7) Check to ensure that all removed parts are back in place. Rein-
stall any necessary parts which have not been reinstalled.
8) Adjust water pump drive belt tension referring to Section 6B.
9) Adjust power steering pump belt tension or A / C compressor
belt tension, if equipped.
Refer to Section 0B.
10) Refill engine with engine oil referring to “ENGINE OIL
CHANGE” in Section 0B.
11) Connect negative cable at battery.
12) After completing installation, check oil pressure by running en-
gine.

REMOVAL
1) Disconnect negative cable at battery.
2) Remove timing belt as previously outlined and remove camshaft
timing belt pulley (1) by using special tool.

4) Disconnect CMP sensor coupler from CMP sensor.
5) Remove CMP sensor case (1) from cylinder head.
Place a container or rag under CMP sensor case, for a small
amount of oil flows out during removal of case.
6) After loosening all valve adjusting screw lock nuts (2), turn ad-
justing screws (1) back all the way to allow all rocker arms (3) to
move freely.
7) Remove camshaft housing and camshaft.
NOTE:
To remove camshaft housing bolts, loosen them in such or-
der as indicated in figure, a little at a time.
8) Remove timing belt inside cover (2).
9) Remove intake rocker arm (1) with clip (2) from rocker arm shaft
(3).
NOTE:
Do not bend clip when removing intake rocker arm.

10) Remove rocker arm shaft bolts (1).
11) Remove exhaust rocker arms (1) and rocker arm spring (2) by
pulling out rocker arm shaft to battery side after removing bat-
tery.
INSPECTION
Adjusting Screw and Rocker Arm
If tip of adjusting screw (1) is badly worn, replace it.
Rocker arm (2) must be replaced if its cam-riding face (3) is badly
worn.
Rocker Arm Shaft Runout
Using “V” blocks and dial gauge, check runout. If runout exceeds
its limit, replace rocker arm shaft.
Runout limit: 0.10 mm (0.004 in.)

Rocker Arm-to-Rocker Arm Shaft Clearance
Using a micrometer and a bore gauge, measure rocker shaft dia.
and rocker arm l.D.
Difference between two readings is arm-to-shaft clearance on
which a limit is specified.
If limit is exceeded, replace shaft or arm, or both.

Camshaft Journal Wear
Check camshaft journals and camshaft housings for pitting,
scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder head with
housing. Never replace cylinder head without replacing housing.

Check clearance by using gaging plastic.
The procedure is as follows.
1) Clean housing and camshaft journals.
2) Install camshaft to cylinder head.
3) Place a piece of gaging plastic the full width of journal of cam-
shaft (parallel to camshaft).
4) Install camshaft housing referring to “INSTALLATION” of the fol-
lowing page.
5) Tighten camshaft housing bolts in such order as indicated in fig-
ure a little at a time till they are tightened to specified torque.

NOTE:
Do not rotate camshaft while gaging plastic is installed.
6) Remove housing and using scale (2) on gaging plastic (1) enve-
lope, measure gaging plastic width at its widest point.

Replace camshaft or cylinder head assembly whichever the dif-
ference from specification is greater.
