(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All vacuum lines properly connected
(e) SFI system wiring connectors fully plugged
(f) All operating accessories switched OFF
(g) Ignition timing check correctly

2. CONNECT TOYOTA HAND±HELD TESTER OR OBDII
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect a TOYOTA hand±held tester or OBDII scan tool
to the DLC3.
(c) Please refer to the TOYOTA hand±held tester or OBDII
scan tool operator's manual for further details.
3. INSPECT IDLE SPEED
(a) Race the engine at 2,500 rpm for approx. 90 seconds.
(b) Check the idle speed.
Idle speed (w/ Cooling fan OFF): 700 ± 50 rpm
If the idle speed is not as specified, check the IAC valve and air
intake system.
4. DISCONNECT TOYOTA HAND±HELD TESTER OR

ON±VEHICLE INSPECTION
1. REMOVE OIL PAN AND OIL STRAINER
(See page LU±7)
2. INSPECT BACKLASH OF CRANKSHAFT GEAR AND
NO.1 BALANCE SHAFT GEAR
NOTICE:
Backlash between the crankshaft gear and No.1 balance
shaft gear varies with the rotation of the balance shaft and
the deviation of the crankshaft gear. Accordingly, it is nec-
essary to measure the backlash at the 4 points shown in
the illustration on the left.
(a) Turn the crankshaft 2 or 3 times to settle the crankshaft
gear and No.1 balance shaft gear.
(b) When No.1 piston is at TDC, check that the punch marks
C shown in the illustration of the balance shafts are
aligned with the grooves of the No.2 housing.
(c) Check that punch marks A and B are at the positions on
the No.1 balance shaft indicated in the illustration.
(d) First turn the crankshaft clockwise, and align the groove
of the No.2 balance shaft housing with punch mark A of
the No.1 balance shaft.

(e) Set SST and a dial indicator as shown in the illustration.
SST 09224±74010
HINT:
Make sure that the stem of the dial indicator is perpendicular to
the SST and that it is placed in the middle of the 3rd indentation.
(f) Lightly turn the No.1 balance shaft by hand until resis-
tance is felt, and measure the backlash.
HINT:
Turn the No.1 balance shaft 4 or 5 times to provide a
steady backlash reading.
To prevent excessive backlash due to thrust clearance,
measure the backlash while pressing on the rear of the
No.1 balance shaft.
Standard backlash (at punch mark A):
0.025 ± 0.065 mm (0.0010 ± 0.0026 in.)
NOTICE:
Do not turn the No.1 balance shaft strongly.
(g) Remove the dial indicator and SST.
(h) Turn the crankshaft clockwise to align the groove of the
No.2 housing with punch mark B.
(i) Set the dial indicator. (See step (e))
(j) Measure the backlash. (See step (f))
Standard backlash (at punch mark B):
0.025 ± 0.085 mm (0.0010 ± 0.0033 in.)
(k) Remove the dial indicator.
(l) Turn the crankshaft clockwise again to align the groove
of the No.2 housing with punch mark A.
(m) Set the dial indicator. (See step (e))
(n) Measure the backlash. (See step (f))
Standard backlash (at punch mark A):
0.025 ± 0.065 mm (0.0010 ± 0.0026 in.)
(o) Remove the dial indicator.

(p) Turn the crankshaft clockwise again to align the groove
of the No.2 housing with punch mark B.
(q) Set the dial indicator. (See step (e))
(r) Measure the backlash. (See step (f))
Standard backlash (at punch mark B):
0.025 ± 0.085 mm (0.0010 ± 0.0033 in.)
(s) Remove the dial indicator.
If even one of the 4 points measured above exceeds the back-
lash specification, adjust the backlash with new spacers.
NOTICE:
Use the same size spacers for both the left and right sides.
HINT:
Varying the spacer thickness by 0.02 mm (0.0008 in.)
changes the backlash by about 0.014 mm (0.0006 in.).
If the backlash is greater than the permitted maximum,
select a thinner shim.
If the backlash is less than the specification, select a thick-
er shim.
3. REPLACE NEW SPACERS
(a) Uniformly loosen the 6 bolts in the sequence shown.
(b) Replace the spacers with new ones.
4. TIGHTEN BALANCE SHAFT ASSEMBLY
While pulling the center part of the engine balancer in the direc-
tion of the arrow, uniformly tighten the 6 bolts in several passes,
in the sequence shown.
