4. Damper
6A1-22 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
2) Install tensioner (2) and tensioner plate (3):
Do not tighten tensioner bolt (1) with wrench yet. Hand tighten
only at this time.
Check to ensure that plate movement in arrow direction as
shown in figure causes tensioner to move in the same direction.
If no associated movement between plate and tensioner occurs,
remove tensioner and plate again and reinsert plate lug into ten-
sioner hole.
3) Check that timing mark (2) on camshaft timing belt pulley is
aligned with “V” mark (1) on cylinder head cover. If not, align two
marks by turning camshaft but be careful not to turn it more than
its allowable turning range which is described on previous page.
4) Check that timing mark (2) on crankshaft timing belt pulley is
aligned with arrow mark (1) on oil pump case. If not, align two
marks by turning crankshaft but be careful not to turn it more
than its allowable turning range which is described on previous
page.
5) Install timing belt and tensioner spring (2).
With two sets of marks aligned and tensioner plate pushed up,
install timing belt on two pulleys in such a way that drive side (1)
of belt is free from any slack.
And then install tensioner spring as shown in figure, and hand-
tighten tensioner stud (3).
NOTE:

When installing timing belt, match arrow mark (
) on
timing belt with rotating direction of crankshaft.

In this state, No. 4 piston is at top dead center of compres-
sion stroke.

4. Guide seal

7) Remove oil pump assembly (1) after removing bolts (2).
DISASSEMBLY
1) Remove oil level gauge guide bolt (3) and pull out guide (2) from
oil pump (1).
2) Remove rotor plate (1).
3) Remove outer rotor (1) and inner rotor (2).
INSPECTION

Check oil seal lip for fault or other damage. Replace as necessary.

6A1-30 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
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.

1. Oil pump
1. No. 1 bolts (short)
2. No. 2 bolts (long)
ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE) 6A1-31
4) Install rotor plate. Tighten 5 screw securely.
After installing plate, check to be sure that gears turn smoothly
by hand.
Tightening Torque
(a): 11 N
.m (1.1 kg-m, 8.0 lb-ft)
5) Apply engine oil to guide seal (3) and install guide seal and guide
(2).
INSTALLATION
1) Install two oil pump pins and oil pump gasket to cylinder block.
Use a new gasket.
2) To prevent oil seal lip from being damaged or upturned when
installing oil pump to crankshaft, fit special tool (Oil seal guide)
to crankshaft, and apply engine oil to special tool.
Special Tool
(A): 09926-18210
3) Install oil pump to cylinder block.
As there are 2 types of oil pump bolts, refer to figure for their cor-
rect use and tighten them to specified torque.
Tightening Torque
(a): 11 N
.m (1.1 kg-m, 8.0 lb-ft)
4) Install rubber seal between oil pump and water pump.

6A1-32 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
5) Install timing pulley key (2) and crank timing belt pulley (3) and
crankshaft pulley pin (1). Refer to figure for proper installation
of these parts.
With crankshaft locked using flat end rod or the like (5), tighten
crank timing belt pulley bolt (4) to specified torque.
Tightening Torque
(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.

12) After completing installation, check oil pressure by running en-
gine.

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.
